oxyCLONE PRO Series 20 Site Cloning System

The oxyCLONE PRO Series 20 Site Cloning System is a compact, recirculating aeroponic cloner designed for propagating cuttings from a wide variety of plants. It holds 20 stem cuttings at once and uses a combination of a submersible water pump and a dedicated air pump to maintain continuous dissolved oxygen at the root zone — the key mechanism behind oxyCLONE’s approach to cloning. Powered by Active Aqua’s BPA-free AAPW160 submersible pump and AAPA3.2L single-outlet air pump.

Why Choose the oxyCLONE PRO Series 20

The oxyCLONE PRO Series 20 is built around a dual-aeration approach that distinguishes it from passive or mist-only cloning systems. Here is what makes it worth considering over alternatives in the same price range.

• Dual-source dissolved oxygen delivery: The submersible AAPW160 water pump creates constant turbulence in the reservoir while a Venturi valve draws in ambient air at the pump intake — this passive air injection happens alongside the dedicated 4-inch circular air diffuser driven by the AAPA3.2L air pump. Both mechanisms run simultaneously, keeping dissolved oxygen levels high throughout the reservoir at all times.
• Evaporative cooling built in: The open-top design around each cloning site allows water to evaporate at the stem collar, which dissipates heat from the reservoir. This passive cooling effect helps prevent the temperature spikes that slow root development in enclosed systems.
• No leak or clog design: The reservoir lid and collar system is engineered to avoid the overflow and spray-nozzle clogging issues common in aeroponic misting cloners. The recirculating flow stays below the collar level, keeping the stem-to-water interface consistent without periodic nozzle maintenance.
• BPA-free pump components: Both the water pump and air pump are Active Aqua units manufactured without BPA in the wetted plastic parts. This matters for clones that will eventually enter a food or medicinal harvest cycle.
• Compact footprint: At just over 5 lb, the system is sized for propagation benches, shelving, or dedicated clone tents where space is limited. Twenty sites is enough for a steady rotation through a medium-sized grow operation without requiring a dedicated propagation room.

Best Uses for the oxyCLONE PRO Series 20

This cloning system is suited to growers who take cuttings on a regular basis and want a reliable aeroponic setup without a large equipment investment.

• Perpetual garden propagation cycles: The 20-site capacity is well matched to perpetual harvest schedules where a grower stages new clones every 1–2 weeks. Taking cuttings in batches of 10–20 keeps the clone tent or propagation area continuously occupied without waiting for a larger unit to fill.
• Vegetative cuttings from a variety of species: The system is designed for soft-wood stem cuttings from a broad range of plant types. Growers working with herbs, tomatoes, peppers, cannabis, and similar plants with semi-succulent stems typically see consistent results with aeroponic oxygenation.
• Situations where clogged mist nozzles are a recurring problem: Growers who have dealt with blocked spray heads in traditional aeroponic cloners often switch to the recirculating reservoir approach for its lower-maintenance operation. The oxyCLONE design eliminates the spray nozzle entirely, removing that failure point.
• Compact propagation setups: If your propagation area is a 2×2 or 2×4 tent, the OX20SYS fits easily with room for humidity domes and clone lighting. It pairs naturally with 3-gallon fabric pots in the next stage of vegetative growth after transplant.
• Growers using 5-gallon buckets for mixing nutrient water: The reservoir fill process is straightforward, and growers who already use gamma seal lids on mixing buckets can maintain a clean, dedicated clone-water mixing container alongside the cloner.

oxyCLONE PRO Series 20 vs Similar Cloning Systems

The most common comparison for the OX20SYS is against other recirculating or aeroponic cloners in the 16–24 site range. The key differentiating factors are aeration method, pump quality, and maintenance requirements.

Many entry-level cloners in this site count use only a submersible pump with spray manifold nozzles to wet the stem bases. Over time, mineral deposits from tap or hard water partially block those nozzles, reducing spray coverage unevenly across the tray. The oxyCLONE design removes the spray nozzle entirely and instead uses a reservoir-level turbulence plus diffuser approach, which is inherently less susceptible to mineral clog buildup.

Compared to larger 30–50 site systems, the 20-site OX20SYS trades raw capacity for a smaller physical footprint and lower upfront cost. For a grower who does not need 30+ clones per cycle, the smaller unit is easier to maintain and requires less water per fill. Growers who eventually need more capacity can run two OX20SYS units side by side rather than stepping up to a single larger system, which gives some redundancy if one unit needs cleaning.

The inclusion of Active Aqua brand pumps (rather than generic no-name OEM pumps) is a practical consideration: replacement parts and compatible tubing for Active Aqua pumps are widely stocked at hydroponics retailers, which simplifies maintenance over the life of the system.

Compatibility

The oxyCLONE PRO Series 20 is a self-contained system that includes all components needed for operation. The following notes apply to integration with common propagation room setups.

• Electrical: Both Active Aqua pumps (AAPW160 and AAPA3.2L) are designed for standard North American 120V outlets. A single power strip with two outlets is sufficient. No special voltage or amperage requirements are noted in manufacturer documentation.
• Clone collars / neoprene inserts: The system uses standard 2-inch neoprene clone collars. Replacement collars and compatible aftermarket inserts (including oxyCLONE’s own oxyCERTS) are widely available and fit the 20 molded collar seats in the lid.
• Water type: The system works with RO water, tap water conditioned to remove chlorine and chloramine, or light-nutrient clone solution. Growers using hard tap water should plan more frequent reservoir cleaning to prevent mineral scale on the pump impeller.
• Clone tents and propagation rooms: The unit’s footprint fits within a 2×2 tent with space to spare. For environmental humidity control, a dome or humidity tent placed over the cloning lid is compatible with the standard lid profile.
• Growing media for transplant: After clones root, they transplant into any standard growing media. Growers using 20-gallon fabric pots for vegetative and flowering stages will find the rooted clone size from the OX20SYS appropriate for direct transplant into a smaller nursery pot first.

Usage Guidelines

The following guidelines cover day-to-day operation of the oxyCLONE PRO Series 20 once the system is set up and running with cuttings in place.

• Reservoir water level: Fill the reservoir so the water level reaches the base of the neoprene collars but does not submerge the stem above the collar. Maintain this level by topping off with plain pH-adjusted water as evaporation occurs. Check daily during the first week.
• pH range: Most cuttings root most reliably in the pH 5.5–6.5 range. Check reservoir pH every 2–3 days and adjust as needed with pH Up/Down solutions. Avoid pH swings greater than 0.5 in a 24-hour period while roots are initiating.
• Nutrient solution: Plain RO water or very light clone-specific nutrient solution (EC 0.3–0.6 mS/cm) is typical for the first 7–10 days. Heavier nutrient concentrations can stress the cutting before roots are established.
• Light and temperature: Keep the reservoir water temperature between 68–75°F (20–24°C). Ambient air temperature in the propagation area should remain in the 70–80°F range. Low-intensity fluorescent or LED clone lighting (18/6 or 24/0 photoperiod) is appropriate; avoid high-intensity fixture heat directly above the cloner.
• Pump operation: Run both pumps continuously (24 hours). Interrupting pump operation reduces dissolved oxygen and can allow anaerobic conditions to develop in the reservoir, which promotes root rot.
• Reservoir cleaning: Drain and clean the reservoir every 7–10 days or whenever the water becomes visibly cloudy or develops odor. Rinse with a dilute hydrogen peroxide solution (3 mL of 3% H2O2 per liter of water), then flush with plain water before refilling.

How to Set Up the oxyCLONE PRO Series 20

Initial setup takes approximately 15–20 minutes. Have pH-adjusted water, clone collars, and rooting gel or powder ready before beginning.

1. Inspect the unit: Remove all components from packaging and verify the reservoir tray, lid, submersible pump (AAPW160), air pump (AAPA3.2L), tubing, and 4-inch air diffuser are present. Check for any visible damage before filling.
2. Position the air diffuser: Place the circular 4-inch air diffuser in the bottom of the reservoir tray. Connect it to the AAPA3.2L air pump via the supplied tubing, routing the tubing over the rim of the tray and to the air pump placed outside and above the reservoir (to prevent back-siphon).
3. Install the submersible pump: Place the Active Aqua AAPW160 pump in the reservoir tray alongside the air diffuser. Connect the Venturi valve attachment per the pump instructions — this is the fitting that draws ambient air into the water stream. Route the pump power cord over the reservoir rim.
4. Fill the reservoir: Add pH-adjusted water (pH 5.8–6.2) until the level is just below the collar seats in the lid. Do not overfill. Place the lid on the reservoir tray.
5. Install clone collars: Press neoprene clone collars into each of the 20 collar seats you plan to use. Unused sites can be left capped or covered to limit evaporation and light entry into the reservoir.
6. Power on and test: Plug in the submersible pump and air pump. Confirm water is circulating and that the air diffuser is producing visible bubbles. Check that the Venturi valve is drawing air (you should hear a faint hiss near the pump body). Verify no leaks around the lid seal.
7. Insert cuttings: Take cuttings at a 45-degree angle with a clean, sharp blade. Apply rooting gel or powder to the cut end, then push the stem gently through the neoprene collar until the cut end is 1–1.5 inches below the collar. The stem should be held snugly without crushing the collar.
8. Cover and monitor: If humidity domes are used, place them over the cuttings to maintain high relative humidity (80–90%) during the first 5–7 days while stomata are closing. Check for root emergence at the 7–10 day mark by lifting a collar and inspecting the stem.
