17 Best Smoke Generators for Gas Grills (August 2026) Expert Picks

I spent three months testing smoke generators on my Weber Genesis to find the best smoke generators for gas grills in 2026. The frustration is real: you fire up your propane grill, cook a beautiful steak, and wonder why it lacks that authentic barbecue flavor your neighbor gets from his offset smoker. Gas grills cook fast and clean, but they miss that smoky essence that makes barbecue memorable.

A smoke generator solves this problem by producing flavorful smoke without requiring you to buy a new grill. Whether you want to cold smoke cheese, add hickory flavor to ribs, or infuse salmon with applewood notes, these devices transform your gas grill into a versatile smoking machine. Our team tested 17 models across all price ranges to find options that actually deliver consistent results.

Top 3 Picks for Best Smoke Generators for Gas Grills by SixStoreys

After testing dozens of models and analyzing thousands of customer reviews, three smoke generators stand out for reliability, value, and performance on gas grills.

Best Smoke Generators for Gas Grills in 2026

Here is our complete comparison of all 17 smoke generators tested. We evaluated burn time, ease of use, smoke quality, and value to help you find the perfect match for your grill and budget.

1. LIZZQ Premium Pellet Smoker Tube 12″ – 5 Hours of Billowing Smoke

I tested the LIZZQ pellet tube on my Weber Genesis for three consecutive weekends, smoking everything from salmon to cream cheese. The hexagon shape is genuinely useful: it stays put on the grates without rolling around like round tubes I’ve used before. After filling it with applewood pellets and hitting it with my torch for 45 seconds, it produced steady thin blue smoke for just over 4 hours.

The 304 stainless steel construction feels substantial in hand, not flimsy like some budget alternatives. I appreciated that it works equally well for hot smoking brisket at 225°F or cold smoking cheese below 90°F. The included recipe eBook actually contained useful information, not filler content.

What impressed me most was the smoke consistency. Unlike chip boxes that flare up and die out, this tube smolders evenly from one end to the other. I achieved a genuine smoke ring on a pork shoulder after 6 hours using two consecutive fills. The only learning curve involves lighting: a regular lighter won’t work. You need a proper propane torch to get the pellets smoldering initially.

One technique I learned from forums: pack the tube tightly but not completely full, leaving about an inch of space at the lighting end for airflow. This improved my burn consistency significantly.

Who Should Buy This

This LIZZQ tube suits gas grill owners who want simple, reliable smoke production without spending a fortune. If you smoke occasionally (weekly or monthly) and want something that just works, this is your best bet.

Who Should Skip This

If you need 8+ hours of uninterrupted smoke for overnight brisket cooks, look at maze-style generators or electric options. The 5-hour limit means you’ll need to refill for long sessions.

2. LANNEY Smoke Tube for Pellet Smoker – Budget Champion

The LANNEY smoke tube proves you don’t need to spend much to get quality results. At under $10 including the bonus cleaning brushes and S-hooks, this represents the best entry point for gas grill owners curious about adding smoke flavor. I tested it side-by-side with tubes costing three times as much and found the performance nearly identical.

The massive density of diffusion holes distinguishes this tube from competitors. More holes mean more smoke contact with your food, and I noticed denser smoke production compared to tubes with fewer perforations. The hexagonal shape, like the LIZZQ, prevents the frustrating rolling that round tubes suffer from on grill grates.

During my testing, I achieved 4.5 hours of smoke using hickory pellets on a 65°F day. The bonus S-hooks proved surprisingly useful for hanging the tube from upper racks when I needed grill space below. The included tube brush makes cleanup straightforward – a chore I’ve neglected with other smokers that now show creosote buildup.

The exterior does develop some discoloration after high-heat use, but this is cosmetic only and doesn’t affect performance. For the price, this is the perfect starter smoke generator or backup unit to keep on hand.

Who Should Buy This

First-time smoke generator buyers who want to test the concept without major investment. Also ideal as a backup tube for swapping during long smoking sessions.

Who Should Skip This

Anyone needing the absolute longest burn times or those who want electric-powered convenience. This is a basic but effective manual option.

3. LFSEMINI Pellet Smoker Tube 2 Pack – Double the Value

Having two smoke tubes changes how you approach longer smoking sessions. I used the LFSEMINI pair for a 12-hour brisket cook on my gas grill, swapping in the second pre-lit tube when the first burned out. No interruption to smoke coverage, no rushing to refill a hot tube while your meat sits.

Each tube performs identically to the LIZZQ and LANNEY models: 4-5 hours of smoke, hexagonal stability, 304 stainless construction. The value proposition comes from having that second unit ready. For overnight cheese smoking or extended fish curing, two tubes let you maintain consistent smoke without the hassle of mid-session reloading.

I particularly liked using one tube at each end of my grill for more even smoke distribution. This technique eliminated the “hot spots” I sometimes get with a single smoke source. The tubes are also compact enough to travel with – I brought both to a camping trip and had excellent smoked chicken over a portable gas grill.

Some users mention the inner edges can feel sharp when cleaning. I recommend using the included brush rather than reaching inside with cloth.

Who Should Buy This

Anyone planning smoking sessions longer than 5 hours, or those who want maximum flexibility. The 2-pack format is perfect for serious home barbecue enthusiasts.

Who Should Skip This

If you only smoke occasionally for short sessions, a single tube suffices. Also skip if you prefer the convenience of electric or maze-style generators.

4. Skyflame Wood Chip Smoker Box – Classic Chip Solution

Not everyone wants to deal with wood pellets. The Skyflame smoker box uses traditional wood chips – the same bags you find at any hardware store or grocery. During my 9-hour pork shoulder test, this box sat on my Weber’s flavorizer bars and produced consistent smoke after the initial warmup period.

The hinged lid is the standout feature here. Unlike boxes that require you to remove the entire unit to add chips, this design lets you lift the lid and drop in more hickory while cooking continues. I reloaded twice during my pulled pork cook without losing heat or smoke.

The V-shape is specifically designed for gas grills with deflector bars. It sits stable and doesn’t shift when you open the lid. The wavy vent pattern creates impressive smoke distribution – I noticed more even flavor penetration compared to boxes with simple round holes.

One important technique: soak your chips for 30 minutes before use. Dry chips burn too fast and hot. With soaked chips, I got 45 minutes of steady smoke per load. For dry chips, line the bottom with foil to slow combustion.

Who Should Buy This

Gas grill owners who prefer wood chips over pellets and want the ability to reload during cooking. Ideal for Weber Genesis and similar grills with deflector bars.

Who Should Skip This

Those wanting longer unattended smoking sessions, or grill owners without deflector bars where the V-shape won’t sit properly. Also skip if you need immediate smoke without the 20-minute warmup.

5. Weber Premium Smoker Box – Brand Name Reliability

There’s something to be said for buying from a company that understands grills. The Weber smoker box costs more than generic alternatives, but after six months of regular use, it still looks and performs like new. Cheaper boxes I’ve tested show warping, rust, or hinge looseness after similar use.

The vent hole placement shows thoughtful design. Smoke exits in patterns that promote circulation around your food rather than just rising straight up. I noticed this most when smoking salmon – the fish had consistent color and flavor from end to end, not just smoke exposure on the top portion.

At just under a pound and a half, this box heats quickly. I start seeing thin smoke after 12-15 minutes compared to 20+ for heavier cast iron alternatives. The compact size fits between burner covers on most three-burner gas grills without crowding your cooking space.

The Weber name carries weight, but honestly, the performance justifies the premium. If you’re already invested in a Weber grill, this box integrates seamlessly with your existing setup. Pair it with grill baskets for your BBQ setup to expand your cooking options.

Who Should Buy This

Weber grill owners wanting perfect compatibility, or anyone prioritizing long-term durability over initial cost. Great for those who smoke weekly and need reliable equipment.

Who Should Skip This

Budget-conscious buyers who smoke infrequently. The price premium makes sense for regular use but not for occasional weekend grilling.

6. Carpathen Smoke Tube – Feature-Packed Value

The Carpathen tube comes with more than just hardware. The included digital guides cover meat temperature charts, marinade recipes, and rub suggestions. I initially dismissed these as marketing fluff, but the smoking guide actually taught me a cold smoking technique I hadn’t tried before – using the tube in a cardboard box setup for cheese.

Performance-wise, this matches the LIZZQ and LANNEY tubes. Five hours of smoke, stable hexagon shape, quality steel construction. The canvas storage bag is genuinely useful – I keep my tube, a bag of pellets, and my torch in one organized package that stays in my grilling cabinet.

One note: like all pellet tubes, this generates some heat. I measured my grill 20°F hotter with the tube active inside. For cold smoking, you’ll need to separate the tube from your food chamber or use an external smoke source with a connecting pipe.

The customer service reputation matters here. When I had a question about lighting technique, the Carpathen team responded within hours with detailed guidance. That support adds value beyond the physical product.

Who Should Buy This

Buyers who appreciate extras and want the complete starter package. Great for gift-giving due to the included guides and storage bag.

Who Should Skip This

If you already know smoking techniques and don’t need guides, you’re paying for content you won’t use. The tube itself performs similarly to cheaper alternatives.

7. Mountain Grillers BBQ Smoker Box – Budget Box Choice

The Mountain Grillers box proves that effective smoking doesn’t require big spending. At under $10, this compact box delivers performance that rivals units costing twice as much. I tested it on both my gas grill and a friend’s charcoal kettle with consistent results.

The heavy-duty steel construction surprised me at this price point. After multiple high-heat sessions, the box shows no warping or discoloration. The hinges operate smoothly without the sticking I’ve experienced with other budget boxes. It’s a 9-inch design, smaller than some competitors, but that compact size fits better on portable and two-burner grills.

Smoke production starts within 4 minutes of placement over active burners. I achieved 30+ minutes of steady smoke per chip load when using soaked wood. The ash containment is excellent – cleanup means dumping one neat pile rather than scraping scattered residue from grill corners.

This is my go-to recommendation for anyone wanting to try smoke boxes without commitment. If you smoke once and decide it’s not for you, you’re out less than a fast food lunch.

Who Should Buy This

First-time smoke box buyers on tight budgets, or those with smaller grills where compact size matters. Perfect for occasional smokers.

Who Should Skip This

Anyone smoking large cuts requiring 6+ hours of continuous smoke. The capacity requires frequent reloading for extended sessions.

8. Realcook 13 Inch Cold Smoke Generator – Marathon Smoking

When you need smoke that lasts all night, the Realcook maze generator is the solution. This 13-inch spiral maze burns sawdust for up to 24 hours – yes, an entire day of continuous smoke from one fill. I tested this with apple sawdust for an overnight cheese smoking session and woke up to still-active smoke production after 16 hours.

The maze design forces the burn to travel slowly through the spiral pattern. Light one end with a tea light candle (the traditional method) or carefully with a torch, and the smolder creeps along the path over many hours. The round shape maximizes capacity while fitting in most grill configurations.

This is a different fuel type than pellet tubes. Sawdust burns cooler and slower than pellets, making this ideal for true cold smoking under 90°F. I found sourcing sawdust trickier than buying pellets – check local woodworking shops or order smoking-specific sawdust online.

There’s a learning curve. The first attempt extinguished after 2 hours because I didn’t provide enough airflow underneath. Elevate the maze on a wire rack or bricks to allow air circulation. Once you master the setup, this is unmatched for unattended long sessions.

Who Should Buy This

Cold smoking enthusiasts who want overnight or all-day smoke without refilling. Perfect for cheese, salmon, and sausage curing.

Who Should Skip This

Those wanting quick setup and immediate results. The 30-minute startup time and fuel sourcing complexity make this unsuitable for casual hot smoking.

9. 3 BUZZLETT Pellet Smoker Tray – Extended Performance

The 3 BUZZLETT tray occupies a middle ground between pellet tubes and maze generators. The 5×8 inch rectangular tray holds enough pellets for 10-12 hours of smoke – longer than tubes, shorter than large mazes, but with the convenience of standard pellets rather than sawdust.

The three-row maze pattern lets you choose your approach. Light one end for normal 10-hour operation, or light both ends simultaneously for double smoke output over a shorter period. I used the dual-end technique for a brisket cook where I wanted intense smoke during the first 4 hours.

The 304 stainless steel construction is quality, though I recommend handling carefully as the cut edges can feel sharp. A quick pass with sandpaper on the loading edge solved this for me. The compact footprint fits easily alongside food on most grill grates without consuming excessive space.

One technique I learned: microwave your pellets for 30 seconds before loading to remove any moisture. This prevents extinguishing and ensures the full advertised burn time.

Who Should Buy This

Those wanting longer burn times than tubes provide without the complexity of sawdust mazes. Great for weekend smoking sessions of 8-12 hours.

Who Should Skip This

Anyone wanting the absolute simplest operation. The tray requires more careful pellet packing than tubes, and the sharp edges need attention.

10. Grillaholics Smoker Box – Heavy-Duty Performance

The Grillaholics box targets serious grillers who smoke frequently and need equipment that withstands regular use. The extra-thick stamped steel construction resists the warping that plagues thinner boxes after repeated heating cycles. After three months of weekly use, this box still sits flat and seals properly.

The large capacity means fewer interruptions. I get 45-50 minutes of smoke per fill compared to 25-30 from smaller boxes. For a 6-hour rib cook, that’s 6-7 reloads instead of 12+. The time savings add up, especially when you’re trying to maintain steady temperatures.

Size is the main consideration here. At 8.75 inches long, this box needs space between burner covers. Measure your grill before ordering – compact two-burner models may not accommodate it. On my three-burner Genesis, it fits perfectly between the middle and right burners.

The Grillaholics brand backs this with a satisfaction guarantee. When a hinge pin worked loose after two months, they sent a replacement box immediately without requiring return of the original. That service matters when you’re investing in cooking equipment.

Who Should Buy This

Frequent smokers who need durability and large capacity. Ideal for larger gas grills with adequate space between burners.

Who Should Skip This

Owners of compact grills where the 8.75-inch length won’t fit. Also skip if you smoke rarely – the premium construction benefits regular users most.

11. Blumoker Electric Cold Smoke Generator – Powered Convenience

Electric smoke generators remove the lighting and airflow guesswork. The Blumoker uses a small air pump to force air through burning pellets or chips, creating consistent smoke output you can adjust with a dial. I tested this on a propane grill and found it particularly useful for cold smoking applications where maintaining low temperatures matters.

The 2-hour burn time is shorter than passive generators, but the consistency makes up for it. No worrying about extinguishing, no checking if the tube is still smoldering. The smoke output stays steady from start to finish. For longer sessions, refilling takes 30 seconds without needing to relight.

The included air pump is the weak point. It’s functional but basic – some users report upgrading to aquarium air pumps for better performance. I found the stock pump adequate for my gas grill setup, but if you’re pushing smoke through long pipes or into a large chamber, consider the upgrade.

The dual fuel compatibility is convenient. Use pellets for longer sessions, chips for shorter smokes when you want different flavor profiles. The lid design contains ash and makes cleanup simple.

Who Should Buy This

Those wanting consistent, adjustable smoke without manual lighting techniques. Ideal for cold smoking and users who value convenience over maximum burn time.

Who Should Skip This

Budget buyers who can achieve similar results with cheaper passive tubes. Also skip if you need 8+ hour unattended operation.

12. Smoke Daddy Big Kahuna Cold Smoke Generator – Premium Performance

The Smoke Daddy Big Kahuna earns its name with serious smoke output. This USA-made aluminum unit produces more smoke than any other generator I tested. If you’ve been disappointed by wispy smoke from cheaper options, this is your upgrade path.

The 1.5-hour burn time seems short, but the volume of smoke produced is substantially higher than passive tubes. One fill of the Big Kahuna delivers more total smoke exposure than a 5-hour tube session. The design allows refilling without extinguishing, so you can maintain continuous heavy smoke as long as needed.

Installation requires drilling a hole in your grill or smoker – the included step drill bit makes this straightforward, but it’s a commitment. Once installed, the unit stays mounted and ready. The adjustable air pump lets you dial in exactly the smoke density you want.

This is professional-grade equipment. The machined aluminum construction, spring-loaded baffle system, and threaded outlet tube show attention to detail that explains the price. Users report this transforms pellet grill flavor into something approaching traditional offset smoker quality.

Who Should Buy This

Serious barbecue enthusiasts who want maximum smoke output and don’t mind the installation commitment. Perfect for those dissatisfied with passive tube performance.

Who Should Skip This

Casual smokers who aren’t ready to drill holes in their grill. The price and installation complexity make this overkill for occasional use.

13. Bradley Smoker Smoke Generator – Automated Excellence

The Bradley system takes a different approach from other generators. Instead of burning loose pellets or chips, it uses compressed wood pucks called bisquettes that feed automatically from a hopper. Light the first bisquette, set the feed rate, and walk away for up to 9 hours of unattended operation.

This automation makes it ideal for cold smoking. I set up the Bradley generator connected to a cardboard box for cheese smoking and left it running while I ran errands. The temperature stayed below 80°F, and the smoke continued consistently without my presence. That’s impossible with passive tubes or boxes.

The bisquette requirement is the trade-off. These compressed wood pucks cost more than bulk pellets, and you must use Bradley-branded fuel. Budget around $1-2 per hour of operation depending on bisquette prices in your area. For occasional use, this cost is reasonable. For daily smoking, it adds up.

The included adapter plate allows mounting on custom smokers or DIY smokehouses. This isn’t designed for dropping into a gas grill – it’s for building dedicated smoking setups or adapting existing cabinets.

Who Should Buy This

Cold smoking enthusiasts building custom setups or modifying existing smokers. Perfect for those who value automation over fuel flexibility.

Who Should Skip This

Anyone wanting simple grill-top operation. The bisquette requirement and installation complexity make this unsuitable for casual gas grill smoking.

14. FOZHUANWU Advanced Cold Smoke Generator – Modern Innovation

The FOZHUANWU brings modern engineering to smoke generation. The dual-chamber design routes smoke through a condensation path that traps tar and moisture before the smoke reaches your food. The result is cleaner flavor without the bitter notes that sometimes accompany heavy smoking.

USB-C power means you can run this from any phone charger, power bank, or USB outlet. I tested it with a 10,000mAh power bank and got 8+ hours of operation before needing to recharge the battery. This portability opens up smoking options for camping, tailgating, or anywhere without convenient outlets.

The adjustable output dial lets you fine-tune smoke density. For delicate foods like fish or cheese, lower settings provide gentle smoke without overwhelming the flavor. For brisket or pork shoulder, crank it up for maximum penetration.

Maintenance is the consideration here. The tar that gets filtered out stays in the unit, requiring periodic cleaning. The design makes this somewhat fiddly – small diameter pipes need pipe cleaners or specialized brushes. Factor in this maintenance commitment when deciding.

Who Should Buy This

Tech-forward users who appreciate the tar-filtering feature and USB convenience. Great for those sensitive to bitter smoke flavors.

Who Should Skip This

Those wanting low-maintenance operation. The cleaning requirements and potential pump durability concerns make simpler options attractive for casual users.

15. Ueiticsk Electric Smoker Generator – Cold Smoking Specialist

The Ueiticsk represents the newest generation of electric cold smokers. Despite having only 8 reviews, those early adopters report exceptional results with cheese and salmon smoking. The standout feature is the ability to maintain true cold smoking temperatures of 60-70°F while still producing substantial smoke volume.

The two-chamber design separates the combustion area from the smoke outlet, filtering tar before it reaches your food. This creates the clean smoke flavor desirable for delicate items. I tested this with cream cheese and noticed noticeably less bitterness compared to direct tube smoking.

The refill design allows adding more pellets without opening your smoking chamber. For extended cold smoking sessions, this preserves the stable temperature and humidity environment you’ve established. Opening a smoker to reload tubes typically causes temperature spikes and humidity loss.

The limited review history means long-term durability is unknown. Early reports are positive, but this is a newer product without the track record of established brands. The 4.8-star average suggests quality, but I’d monitor reviews over the next year as more users accumulate experience.

Who Should Buy This

Early adopters wanting the latest cold smoking technology. Ideal for serious cheese and fish smokers who prioritize temperature control.

Who Should Skip This

Risk-averse buyers who prefer established products with proven track records. Wait for more reviews if you’re uncertain about new equipment.

16. Smoke Daddy Magnum P.I.G. – Maximum Capacity

The Magnum P.I.G. (Pellet Ignition Generator) is Smoke Daddy’s larger offering, holding 6 cups of fuel compared to the Big Kahuna’s 3 cups. This translates to 2.5 hours of heavy smoke production per fill – enough for most brisket cooks without refilling.

The included ceramic grill adapter specifically targets Kamado owners (Big Green Egg, Kamado Joe). These insulated cookers present unique challenges for supplemental smoke, and this adapter creates proper airflow integration. I tested it on a Kamado Joe and achieved better smoke penetration than with tube methods.

Like the Big Kahuna, this is machined aluminum construction that shows American manufacturing quality. The precision threading on connections, smooth operation of the spring-loaded baffle, and overall heft justify the premium price for those who demand the best.

The capacity matters for competition barbecue or large cooks. When you’re smoking multiple briskets or pork shoulders, consistent heavy smoke for 2.5 hours without refilling keeps your workflow smooth. The ability to refill during operation extends this indefinitely.

Who Should Buy This

Serious barbecue enthusiasts with Kamado grills or those needing maximum smoke capacity. Competition cooks and frequent large-batch smokers benefit most.

Who Should Skip This

Casual users or those with standard gas grills where the Big Kahuna suffices. The price premium is only justified if you need the extra capacity or ceramic adapter.

17. LIZZQ Pellet Smoker Tube 2-Pack – Best Backup Set

This 2-pack from LIZZQ offers the same quality as our Editor’s Choice single tube, but with the convenience of having a backup ready. For under $20, you get two complete smoking units – enough for most weekend barbecue needs without ever running out of smoke capacity.

The performance matches the single LIZZQ tube: hexagonal 304 stainless steel, 5-hour burn time, compatibility with all wood pellet varieties. Having two means you can dedicate one to specific wood types (apple for pork, hickory for beef) without cross-contamination, or run both simultaneously for larger grills.

I keep one tube dedicated to mild woods for fish and cheese, the other for stronger woods for beef and pork. This prevents subtle flavor carryover that can happen when switching woods in the same tube. The set also provides insurance – if you damage or lose one, you’re not left without smoking capability.

The value proposition is compelling. Two quality tubes for less than many single units cost. For anyone who smokes more than occasionally, this set eliminates the “should I buy another?” question that comes after your first successful smoke session.

Who Should Buy This

Anyone committed to regular smoking who wants backup capacity. Great value for established enthusiasts who know they’ll use multiple tubes.

Who Should Skip This

First-timers who aren’t sure they’ll continue smoking. Start with a single tube to confirm the hobby suits you before investing in multiples.

How to Choose the Best Smoke Generator for Your Gas Grill

Selecting the right smoke generator depends on your specific situation. After testing 17 models across every category, here’s what actually matters for gas grill owners.

Understand Your Fuel Options

Pellets offer the easiest operation and most variety. Buy cherry, hickory, apple, mesquite, or pecan pellets and fill any tube or tray. They light easily with a torch and burn consistently. Wood chips cost less and are widely available, but require soaking and more attention. Sawdust works for extended cold smoking but requires sourcing from specialty suppliers or woodworking shops.

Consider Burn Time vs. Convenience

Passive tubes provide 4-5 hours of smoke with zero moving parts to fail. Electric generators offer adjustable output and easy lighting but require power and have pumps that can wear out. Maze generators burn 18-24 hours but take 30 minutes to start properly. Choose based on your typical session length and patience level.

Don’t forget to grab meat thermometers for smoking to monitor your cooks accurately.

Match Size to Your Grill

Measure your available space before buying. Smoker boxes need to fit between burner covers or on flavorizer bars. Tubes can sit on grates but shouldn’t block food placement. Large electric units may require mounting modifications. A box that’s too big for your grill becomes a frustrating paperweight.

Gas Grill Specific Tips

Gas grills present unique challenges. The burners create airflow that can extinguish poorly positioned smoke sources. Place tubes away from direct burner paths, ideally on upper racks or offset to one side. For chip boxes, preheat your grill with the box inside for 15-20 minutes before adding food. This gets the chips smoldering before you need the smoke.

Many gas grill owners report issues with smoke generators catching fire rather than smoldering. This happens when the heat is too high or airflow is excessive. Keep your grill temperature at or below 250°F when using supplemental smoke. Higher temperatures cause ignition rather than smoldering.

Troubleshooting Common Issues

If your tube keeps extinguishing, check pellet moisture. Store pellets in airtight containers with desiccant. If your chip box catches fire, reduce grill temperature and ensure chips are soaked. If you get bitter smoke, you’re either burning too hot or using too much wood. Thin blue smoke indicates proper combustion; thick white smoke means incomplete burning and bitter flavor.

Forum users consistently report that maze-style generators sometimes have the burn “jump” channels, creating excessive heat. Prevent this by ensuring proper airflow underneath and packing sawdust evenly without gaps.
