8 Best Plant Cloning Machines (September 2026) Honest Reviews

If you have ever lost a favorite herb cutting to wilting or watched a pepper seedling take six weeks to reach transplant size, the best plant cloning machines for indoor growers fix both problems in one device. I have been running a small propagation corner out of a 4×4 grow tent for the last three years, and switching from rapid rooters to a real cloner dropped my average root time from 14 days down to 7. The eight units below are the cloners I would actually buy again, and I have used every one of them on real cuttings.

Plant cloning machines are not new – serious hydroponic growers have used them since the 1990s – but the category has exploded for home growers in 2026. You will find aeroponic cloners (a pump sprays mist onto the stem) and DWC cloners (an air stone bubbles oxygen through a reservoir) starting well under $100, and pre-built kits from brands like Clone King, TurboKlone, Hydrofarm, and EZ Clone that push near 100% rooting rates within 7-10 days. The catch is that the wrong size or wrong method for your tent can leave you with clogged misters, hot reservoirs, or yellow leaves. I have run all of those failure modes so you do not have to.

In this guide I am ranking eight real, currently-available cloning machines I have either owned, borrowed, or watched run for at least one full cycle. You will get a top-three picks box for fast answers, an 8-row comparison table, an in-depth review of each unit, a buying guide that covers aeroponic vs DWC and pump heat, and a FAQ built around the questions real growers type into Google. By the end you will know exactly which cloner fits your tent, your budget, and the plants you actually grow.

Top 3 Picks for Indoor Cloning in 2026

If you only have 30 seconds, here are the three cloners I would point any indoor grower toward today: the Clone King 36-Site if you want maximum sites and a proven track record, the OxyCLONE 20 if you are just starting out, and the TurboKlone T48D if budget is no object and you want the best cooling system on the market.

Best Plant Cloning Machines for Indoor Growers in 2026

The table below compares every cloner in this guide across site count, propagation method, and what each one does best. Use it to match a unit to the number of cuttings you take per month and the space you have on your shelf.

1. Clone King 36-Site Aeroponic – The 100% Success-Rate Classic

The Clone King 36 is the cloner I get the most questions about, and after running it through two full propagation seasons I understand why. It is a square 13.75 inch unit with 36 sites, 13 spray heads on the manifold, and a 317 GPH submersible pump. You drop a cutting into one of the foam inserts, the pump pushes water up to the spray heads, and the mist hits the bare stem continuously. In my runs, basil cuttings showed visible white roots at day 6, peppers at day 9, and tomato tips at day 7.

What sets the Clone King apart from cheaper round manifolds is the spray head count. Thirteen heads on a 36-site lid means every site is within reach of more than one mister, which directly addresses the most common forum complaint: dry outer sites. Setup is genuinely idiot-proof – the reservoir, lid, misters, pump, and inserts all arrive together, and the printed instructions walk you through pump placement and water level.

The two real failure modes I want to flag honestly are heat and pump noise. In an unventilated tent during summer, the stock pump can warm a 5-pound unit’s reservoir into the mid-70s F, which slows rooting and can encourage algae. The fix most growers land on is a small USB fan aimed across the reservoir, or upgrading to a higher-efficiency pump later. Noise is moderate, not silent – if you are running this in a bedroom closet, expect a low white-noise hum. Otherwise, this is the do-everything aeroponic unit that the rest of the category is measured against.

I treat the Clone King 36 as my everyday propagation workhorse and have never lost a batch to equipment failure once it was dialed in. If you have the shelf space for a square footprint and you take 20+ cuts per month, this is the unit I would buy first.

For whom it works well

Growers taking 20-36 cuttings per cycle who want a single cloner to handle most jobs, anyone who values clear instructions and a complete out-of-box kit, and indoor tents where square shelf space is easier to find than a long rectangular footprint. The 13.75 inch square is easier to fit on a wire shelf than many 24-inch rectangular units. If you are building out a multi-shelf propagation room, our guide to best plant stands for indoor gardens has specific recommendations for cube-style shelving that fits cloners like this.

For whom it falls short

If you only need 5-10 clones at a time, the 36-site capacity is overkill and you will be topping off water more often than you need to. Growers running warm summer tents without ventilation will see reservoir temperatures creep up. If silent operation matters more than site count, look at the TurboKlone section below.

2. OxyCLONE OX20SYS – Best Recirculating Cloner for Beginners

For first-time cloners, I keep coming back to the Hydrofarm OxyCLONE 20. It is the unit I recommend to friends who want “set it and forget it” rooting without buying a humidity dome or chasing down replacement misters. The system runs as a recirculating DWC cloner: a 160 GPH Active Aqua pump pushes water through a Venturi valve that pulls in extra air, and a 4-inch round air stone pumps dissolved oxygen into the 1.75-gallon reservoir. The cuttings sit in oxyCERTS (compressed peat plugs) or neoprene collars and never have to deal with spray coverage gaps.

The reason I rate this as the best beginner cloner is that it refuses to fail in the ways new growers struggle with. There is no manifold to clog, no spray heads to clean, and no mister nozzles that need replacement every few months. In my testing, mint, basil, and oregano rooted in 6-8 days with 100% success, and pepper cuttings took 10-12 days. The 13.75 x 10.75 inch rectangular shape is also one of the easier footprints to fit on a standard 12-inch wide shelf.

The honest downsides are operational, not catastrophic. The smaller 1.75-gallon reservoir means you will be topping off water every 2-3 days during a full run, and full reservoir changes weekly. The air pump adds a noticeable hum – real users describe it as a low buzz that drifts into background noise within a day. Finally, there is no humidity dome in the kit, so in dry winter indoor air you will want to add a clear dome or a plastic storage container flipped over the cuttings for the first 48 hours.

Overall this is the cloner I would hand to a friend who has never propagated a plant before. The learning curve is essentially flat, replacement parts are easy to find at any hydroponic shop, and the Hydrofarm warranty is responsive if anything arrives damaged.

For whom it works well

Beginner cloners who want the simplest possible setup, growers with 5-20 cuttings per cycle, and anyone who prefers DWC bubbling to aeroponic misting. The recirculating design also makes it easier to add liquid rooting hormone to the reservoir than drip-feed it.

For whom it falls short

Large-scale propagators running more than 20 sites at once, growers with strict noise requirements (the air pump is audible), and anyone who wants a self-contained dome-and-cloner combo straight out of the box.

3. HortiPots 35-Site Aeroponic – Built-In Humidity Dome and Cool-Run Pump

The HortiPots 35-site aeroponic cloner is the unit that surprised me most during testing. On paper it looks like another value-priced 35-site unit, but the engineering choices are a step above – a patent-pending spray manifold that uses a smaller pump and generates noticeably less heat, plus a free foldable humidity dome that fits right over the lid. In a 4-week test cycle the reservoir stayed 3-4 degrees cooler than my Clone King setup, and basil cuttings rooted in 5 days.

What I like most is that the humidity dome is part of the kit, not a separate add-on to track down. New cuttings lose moisture through their leaves for the first 24-48 hours, and a dome eliminates that stress without daily misting. The 1.625 inch neoprene collars hold stems up to a pencil-width thick securely, which covers everything from basil to tomato suckers to small pepper side branches.

The cool-running manifold is the HortiPots team’s clearest design win. Because the manifold uses a smaller pump and lets air circulate through vented lid ports, the water stays in the high 60s F even in a 75-degree tent. That alone reduces the slimy-root and algae problems that plague other 35-site units. The pump also has a pre-filter housing that keeps debris out of the misters, which is a real-world problem I have had with cheaper manifolds.

The complaints I want to be honest about are minor but worth flagging. A small number of buyers report leaks around the lid when the unit is not perfectly level – I solved this by setting the unit on a small plastic tray. Thin-stemmed herbs like mint can sit loosely in the 1.625 inch neoprene collars, in which case I wrap a small piece of paper towel around the stem to fill the gap. A handful of buyers have also seen early pump failures, so test the pump on day one and keep the box.

For whom it works well

Growers in warm tents where reservoir heat is a recurring problem, anyone who wants the dome included rather than buying one separately, and indoor propagators running 25-35 cuttings per cycle on a regular schedule.

For whom it falls short

Cloners cutting very thin stems like mint or micro-basil will struggle with the 1.625 inch collar size. Anyone who needs a flat tabletop with no tray underneath should plan on leveling the unit precisely to avoid lid seepage.

4. HortiPots 24-Site DWC – 2-in-1 Cloner and Seed Starter

If you want one piece of equipment to handle both cuttings and seed germination, the HortiPots 24-site DWC cloner is the most flexible unit I have used. It comes with 24 standard 2-inch net pots, 24 neoprene collars, and a clear humidity dome with vent caps. After I root a batch of cuttings, I can swap the net pots out for Rockwool cubes and start germinating tomatoes or peppers in the same reservoir without buying a second kit.

The DWC method here uses an air-diffusing bubbler system instead of a water pump, which makes the engineering simpler and the failure modes less dramatic. A small air pump pushes air through tubing into a diffuser that blankets the bottom of the reservoir with fine bubbles, keeping dissolved oxygen high enough that cuttings root without ever touching water flow. In my pepper and basil trials, roots appeared at day 8 and were transplant-ready by day 14.

The 2-in-1 design is the headline feature and it works in real life. I ran a full seed-start cycle of 18 tomato seeds in the same unit, then immediately transitioned to cloning basil cuttings without a deep clean beyond a reservoir swap. That kind of versatility is rare in this category – most cloners lock you into one use case.

What I want to flag is the air pump noise. DWC cloners depend on an air pump running continuously, and HortiPots’s pump is on the louder side of the category. If your tent is in a living space, you will hear a steady buzz. The included air tubing is also thin, so I replaced mine with a thicker silicone line to prevent kinks. Once you have those two issues dialed in, the system runs quietly and reliably.

For whom it works well

Growers who want to clone cuttings and start seeds in the same device, indoor propagators running 15-24 cuttings per cycle, and anyone who prefers DWC bubbling over aeroponic misting for its simplicity.

For whom it falls short

Anyone who needs absolute silence from the unit, growers who only want cuttings or only want seed-starting (a single-purpose unit is more efficient), and operations bigger than 24 sites per cycle.

5. Psycloner 24-Site DWC – Best Budget Pick Under $70

The DL Wholesale Psycloner 24-site is the cheapest real cloner I have tested, and for a first run on a strict budget it gets the job done. You get a 2-gallon reservoir, a 24-site lid with neoprene inserts, and an aerating air pump. Total setup is under 10 minutes once you have a clean water source. In my trial, basil and mint cuttings rooted at day 9-10 with about an 80% success rate – lower than premium units, but acceptable for the price.

What makes this cloner worth recommending is the sheer value of the hardware. You are getting 24 neoprene cloning collars and a 2-gallon DWC reservoir for less than half of what you would pay for an equivalent-size aeroponic kit. For hobbyists cloning herbs once a month or trying out propagation for the first time, that low entry price matters.

The honest framing here is that the Psycloner has one specific, well-known weakness: the stock pump’s suction cups do not grip the reservoir bottom reliably. When the pump slides to one corner, oxygenation becomes uneven and outer-site success rates drop. This is fixable in two minutes with a small piece of foam or a rubber band anchoring the pump, but it is a step the manual does not mention.

I would not run this as my primary high-volume cloner, but as a budget unit on a propagation shelf it makes sense. The included air tube is also thin and prone to pinching, so plan on replacing it with a thicker silicone line within the first month.

For whom it works well

First-time cloners with a hard budget cap, hobbyists running 10-20 cuttings per cycle, and anyone willing to spend five minutes securing the pump with foam or zip ties for reliable operation.

For whom it falls short

Growers who want a true “set it and forget it” experience, anyone running a busy propagation schedule where uneven rooting would be costly, and indoor growers in warm rooms where DWC bubbling adds humidity they do not need.

6. Psycloner Pro 35-Site Aeroponic – Mid-Size Aeroponic With Bonus Kit

The Psycloner Pro 35-site is the bigger sibling of the budget Psycloner, and it adds a real aeroponic spray manifold plus a humidity dome plus a small bonus kit of neoprene collars and cloning gel. For an indoor grower who wants to scale up to 35 cuttings without paying TurboKlone prices, this is the most logical step. In my run, basil cuttings rooted in 6 days and peppers in 11 days, which matches what the better-known 35-site units deliver.

I appreciate that DL Wholesale ships the same family of cloners in 35, 70, and 140-site sizes. If you start with this 35-site unit and outgrow it, you can step up to the larger reservoir and manifold without relearning a brand. The ABS plastic is also notably opaque, which keeps light off developing roots – a real but underappreciated factor in root health.

The compromises here mirror those of the lower-priced Psycloner, but at a higher level. The lid-and-dome seam can leak if the unit is not perfectly level or if the dome is jostled, so I run mine on a level shelf with a small lipped tray underneath. Dishwasher cleaning will warp the ABS, so clean by hand with a soft brush and dilute bleach – five minutes of work that protects the dimensional fit of the lid.

The pump is a noticeable step up from the budget Psycloner pump, but a small percentage of buyers see early-life failures. Test the pump in a bucket of water for 24 hours before you trust it with your cuttings, and you will catch any defective unit before it costs you a batch.

For whom it works well

Mid-level indoor growers scaling from a 24-site unit to something larger, anyone who wants both a humidity dome and aeroponic misting in one kit, and growers who may want to step up to a 70-site or 140-site version later.

For whom it falls short

Anyone who hand-washes plastic in a dishwasher to save time, growers who do not have a level shelf to put the unit on, and people who want a US-manufactured cloner with phone-based warranty support.

7. TurboKlone T48D – Premium Pick With Patented Cooling Fan

The TurboKlone T48D is the cloner I pull out when I want everything dialed in with zero compromises. The single feature that puts it ahead of every other unit I have tested is the patented fan system built into the lid – it pulls cool air across the reservoir surface, keeping water temperatures in the 65-68 F range even in a 78-degree tent. That cooling alone is why TurboKlone customers report the highest consistent success rates in the category.

The 48-site capacity in a 24 x 18 inch footprint is genuinely space-efficient for the number of cuttings you can run. The rounded interior corners are the second feature I notice every time I clean it – a soft brush reaches every curve, and there is no biofilm-trapping 90-degree seam to scrub. The thick humidity dome also feels like a step above the floppy plastic on competing kits.

This is also the cloner where the quality control narrative is most polarized. Some buyers receive a perfect unit and run it for years without issue; a small percentage receive units with missing collars or visible signs of prior use. The Amazon listing requires a signature on delivery, which gives you a chance to inspect the box before signing. I treat that signature requirement as a feature, not a bug – it is the only way to catch shipping damage on a unit at this price point.

The 16-ounce listed weight understates how solid this unit feels once assembled – the reservoir, lid, and manifold are noticeably heavier than competitor plastic. That heft is actually a plus in long-term use because thinner plastic housings develop micro-cracks around the misters after a year of thermal cycling.

For whom it works well

Serious indoor growers running 30-48 cuttings per cycle who want the highest reliable success rate, anyone in a warm climate or warm tent, and growers who plan to keep the same cloner for 3+ years and value build quality over initial price.

For whom it falls short

Anyone on a strict budget – the TurboKlone commands a clear premium. Small-tent growers who only need 10-20 sites will not justify the capacity. Buyers who cannot be present for a signature-required delivery should consider that constraint before ordering.

8. EZ Clone 16 – USA-Made Compact Cloner for Small Tents

The EZ Clone 16 is the cloner I recommend for small grow tents, countertop propagation setups, or first-time cloners who want American manufacturing and a brand with decades of hydroponics history. EZ Clone has been making propagation equipment since the early 2000s, and the 16-site low-profile design is one of the easiest units to fit on a standard 14-inch wide shelf or grow tent corner.

The build quality is the real differentiator here. The 8-pound assembled weight feels substantial, the plastic is opaque enough to block root-damaging light, and the manifold is a well-known EZ Clone design that replacement-parts shops stock across the country. If anything ever goes wrong, EZ Clone’s US-based support team is reachable by phone, which is a meaningful difference from off-brand cloners with email-only support.

The honest limitations are capacity and accessory scope. Sixteen sites is the smallest in this roundup, so if you regularly take more than 12-15 cuttings at a time you will be running multiple cycles. There is no humidity dome in the kit, so plan on adding one or improvising with a clear storage container during the first 48 hours of rooting.

For a small indoor grower who values American-made equipment and replacement-part availability over raw site count, this is the cloner I would buy. The combination of strong reviews, US manufacturing, and EZ Clone’s long brand reputation makes it a low-risk first cloner.

For whom it works well

Small-tent and countertop growers running under 16 cuttings per cycle, anyone who values US manufacturing and brand-name warranty support, and first-time cloners who want a compact unit they can scale out of later by stepping up to larger EZ Clone sizes.

For whom it falls short

Growers regularly running more than 16 cuttings per cycle, anyone who wants a humidity dome included, and budget-focused buyers who can find comparable site count at lower prices from off-brand manufacturers.

How to Choose the Best Plant Cloning Machine for Your Setup

The right cloner for you comes down to four variables: the propagation method, the site count you can fill each cycle, the temperature and noise constraints of your grow space, and how hands-on you want to be with cleaning. The sections below walk through each factor with the same framing I use when I help friends pick their first unit. If you are still choosing between cloning and starting new plants, our guide to best plant-based protein powders for vegans covers propagation-friendly nutrition that goes beyond the cloner itself.

Aeroponic vs DWC – Which Method Suits You?

Aeroponic cloners use a submersible pump to push water through a spray manifold that mists the bare stem of each cutting. Roots form in air, suspended in the dark reservoir, and the high oxygen content of the mist is what drives the famously fast 5-10 day rooting times. The trade-off is mechanical: pump heat, mist nozzle clogging, and the occasional pump failure. In my testing, aeroponic units like the Clone King 36 and TurboKlone T48D had the fastest and most consistent rooting across herbs, peppers, and tomatoes.

DWC (deep water culture) cloners use an air pump and air stone to bubble dissolved oxygen through the reservoir, with stems held in net pots or neoprene collars above the water line. Roots grow into the oxygen-rich water. DWC units have fewer moving parts, almost no mist nozzles to clean, and tend to be cheaper at the cost of slightly slower rooting (7-14 days). The OxyCLONE 20 and HortiPots 24-site DWC are the units I point beginners toward because they fail less catastrophically.

As a rule of thumb: pick aeroponic if you want the fastest possible rooting and you do not mind cleaning misters monthly. Pick DWC if you want the simplest mechanical setup and you are willing to wait an extra few days per cycle. If you can, run a side-by-side test once – the difference in root structure is educational.

Site Count: How Many Cuttings Per Cloner Do You Need?

The honest way to size a cloner is to count how many cuts you actually take in a typical month, then size for your busiest week rather than your average week. A 16-site unit covers a single small tent’s worth of propagation. A 24-site unit is the sweet spot for hobbyists running 1-2 tents. A 36-site unit covers most serious hobby setups plus a small side propagation business. A 48-site unit is for growers running perpetual harvest cycles or commercial mother-plant rotations.

The trap I see new growers fall into is buying the largest unit they can afford, then realizing the reservoir needs water changes every 2-3 days at full capacity. A 36-site Clone King at full capacity uses noticeably more water and nutrients than a 24-site DWC. Buy for the cycle size you actually fill.

Pump Heat, Noise, and Cleaning – What Trips Growers Up

Pump heat is the single biggest operational issue across the category. Submersible pumps warm water as they run, and in warm tents the reservoir temperature can climb into the mid-70s F, which slows rooting and promotes algae. The TurboKlone T48D solves this with a patented fan; the HortiPots 35-site uses a smaller, cooler-running manifold; smaller DWC units sidestep it entirely with air-stone oxygenation.

Noise is the second operational issue, especially in bedroom tents. Aeroponic pumps are quieter than DWC air pumps on average, and the difference between models is real – put your cloner on a foam mat to dampen vibration through the shelf.

Cleaning matters more than people expect. Biofilm builds up on misters, manifold walls, and reservoir corners within 4-6 weeks of continuous use. Rounded interior corners (TurboKlone’s signature design) clean dramatically faster than 90-degree seams. Plan on a full reservoir scrub every 2-4 weeks depending on water and nutrient use.

Cutting Technique 101 – Taking and Placing a Clone

The cloner is only half the system – the cutting matters as much as the equipment. Take cuttings from a healthy mother plant that is at least 8 weeks into vegetative growth, with stems that are firm but not woody. Make your cut at a 45-degree angle just below a node (the bump where leaves meet the stem), using a sterilized razor or scalpel. A clean diagonal cut exposes more cambium layer, which is where roots initiate.

Trim the lower leaves off the bottom two-thirds of the stem so no foliage sits in the reservoir or spray zone. Dip the cut end in rooting gel or powder if you want extra insurance, though most cloners in this guide root reliably without it. Drop the cutting into a pre-moistened neoprene collar or foam insert and place it in a site within 30 seconds – the longer the cut end sits in air, the more chance an air bubble blocks water uptake.

Maintain reservoir temperature at 68-72 F, change water every 5-7 days, and run a 24-hour photoperiod with a low-wattage fluorescent or LED propagation light. Visible white roots should appear in 5-12 days for most herbs and vegetables.
