Acclimating Your Clones

All of Root 66 Farms, our clones are acclimated or “hardened” meaning they have been exposed to higher light levels and lower temperatures than are used to in the greenhouse. This will maximize transplanting success and reduce plant shock. .

It’s recommended that you perform a similar acclimation on your farm if possible. For a period of several days, Root 66 Farms recommends placing clones outside soon after sunrise on your farm where they can get accustomed to the wind, light and humidity levels. Make sure to move to a shaded area before peak sun. If placed inside, adequate lighting to maintain vegetative photo-period is necessary. They should be placed back into full sun around 4pm for the last part of the day.

To ensure the health of your clones (and CBD yields), it’s all about acclimation to your farm’s environment – soil, sunlight, wind and humidity.


Root 66 Farms recommends planting approximately 2000 clones per acre with late May/ early June planting. Two options are available for transplanting:

Option 1: The first option is to plant clones directly into the field. It is recommended to use a dibble/auger to make a hole one and a quarter times as wide and as deep as the size of the plug. Next, place the clone plug into the hole, ensuring that top surface of the plug is at least a quarter inch below the field soil line. Fill any space around or on top of the clone plug with soil from field. Make sure not to compact the soil – you want good air flow and no soil compaction.

Option 2: The second option is to transplant clones into a container with a larger soil volume. 4” or 6” standard pot size for the first transplant is what we recommend. Use a similar technique described in Option 1 for the container transplant. Note that the root mass is initially contained to the soil volume of the plug. This means that until the clone has rooted into the field or into its new container’s soil, one must irrigate focusing on saturating the actual plug mass.

We recommend on monitoring soil moisture content around the root mass several times daily until roots are actively established, checking and irrigating when necessary.

Irrigation and Fertilization

It is very important that the clone be irrigated in a fashion that allows for an adequate wet to dry cycle. When it is time to irrigate, it is suggested that the clone plug be fully saturated. To accomplish this, one should apply a volume of water great enough to prime the soil. Minutes later, this priming should be followed by a volume of water great enough to fully saturate all the soil so that if one squeezes the clone plug, water will vigorously drip from the bottom.

Hemp does not do well when its “feet stay wet”. Over-saturation can allow for a host of unwanted things including root rot. Conversely, never let the plugs dry to the point of plant wilt. A good rule of thumb for making irrigation decisions is that if the clone plug is not cool to the touch and has a light brown to beige color, it is time to irrigate to full saturation. If one chooses to fertilize the clones before transplanting or directly after transplanting, we recommend using the lowest labeled rate of fertilizer on the product of your choosing. We also encourage using drip irrigation whenever possible (Netafim).
