The EZ‑CLONE® Aeroponic Cloning System does not require a humidity dome.

In fact, we have collected data for over 20 years on using the systems in environments with humidity levels as low as 40% RH. Aeroponic cloning systems accommodate much higher transpiration rates than traditional methods; thus, wilting does not occur as it does in other mediums that cannot provide the amount of water needed to keep a plant from wilting. Additionally, a humidity dome increases the potential for powdery mildew, pest infestation, prevents the cuttings from transpiring naturally, and can resultantly delay rooting times.

Somewhere that is sturdy or stable enough to set the system fully filled. A sturdy table, the floor, or heavy-duty wire racks are all good options. Keep in mind, to keep your water temps. between 70-75°F, it is best to locate the system where the ambient air is less than 75°F.

We recommend reservoir temperatures be maintained between 70-75°F. The optimum temperature is around 72-73°F. Although it is not recommended, 75-80°F can be achieved with the regular & recommended usage of Clear Rez; however, there is a higher probability of pathogenic activity.

We operate all of our testing units in a 70-75°F controlled grow room. We strongly recommend maintaining an ambient air temperature between 68 and 75°F.

T12, T8, or T5 fluorescent bulbs with a Kelvin temp. of 4000K to 6500K work great with a range in canopy PAR value from 50-80 mmols/m2/s. A two-foot dual bulb fixture works well over the 16 and 32 site systems while two foot four bulb fixture works well over the 64 and a four foot four bulb fixture works well for the 128 site system.

LED bulbs work great as well with a Kelvin temp. of 4000K to 6500K and with a range in canopy PAR value from 30-50 mmols/m2/s. Given the specific light output in nanometer wavelength, LEDs tend to be more efficient at delivering higher concentrations of plant usable light; therefore, the desired plant response is generally observed at a lower concentrated PPFD.

18 – 24 hours a day. It’s usually the grower’s preference.

This will generally depend on the intensity of the bulbs, their spacing from one another, and the reflector that it’s housed in. 18-34 inches is generally the distance that most fluorescent will provide the aforementioned PAR values while some LEDs panels may need to be placed at a greater distance. If you observe light-driven chlorosis within the canopy, the light is likely too close and needs to be placed at a further distance from the canopy.

If the exact volume of water is not required for determining the proper ratio for additives, fill your system to the bottom of the manifold.

Generally, tap water is fine; however, if you are in an area with poor quality tap water, RO water (reverse osmosis water) or distilled water is recommended. When using RO water, it can be difficult to stabilize pH due to the lack of pH buffers. If you are experiencing large swings in pH using pure RO with nutrient additives, a 75% RO water to 25% tap water ratio will add pH buffers back into the water which will help the pH stabilization. It is not recommended to run pure RO water, distilled water, or DI water without adding mineral salts back to the water before starting your cloning cycle.

Anywhere between 5.8-6.5. The initial pH set point is recommended at 5.8. These levels are likely to rise daily, so be sure to monitor & readjust to 5.8 accordingly. Once you begin seeing roots, the acceptable pH range is 6.0-6.5 with 6.2 being a sweet spot.

Running your water pump continuously is recommended if your water temperatures are within the desired range. A cycle time of 1 min. on / 4 min. off is suggested if you’re combating heating issues. It is always recommended that your cloning system is in a temperature-controlled environment for the most optimal results possible.

Rooting times vary greatly depending on environmental conditions, species, and the health of the donor plant. Usually, roots will begin to develop around 7-10 days for many herbaceous and softwood cuttings. Hardwood cuttings may take a little longer.

Depending on the medium you are transplanting into, your cuttings are ready to be transplanted when roots are at least 2” long. Typically, longer, more developed roots have a higher success rate. Remember, if roots get too long, they can be trimmed with sterile scissors during transplanting.

Yes, if you’re using the fully sterilizable and reusable EZ‑CLONE®Infinity CollarsTM. We also have our compostable seedling/cloning EZ‑CLONE® Propagation ProTM Collars.

We strongly recommend using improved EZ‑CLONE® Classic Collars each time for the best results. Look at it as a 50 cent per cutting insurance policy to help eliminate the potential for bacterial infection. 50 cents is definitely not worth losing a plant.
