Cannabis plants are very sensitive in the early stages. Special care is needed to ensure that your cannabis clone grows into a beautiful and healthy flower. Our clones are guaranteed to be pest and disease free, but to ensure you are successful with the plants you choose, here are some tips on how to care for them. Please inspect your clones before leaving any retail location and if you see any issues, please report them immediately to the retail staff.
The flowering cycle is the point at which the plant is receiving roughly 12 hours of light and 12 hours of darkness. In an outdoor garden, the plant is naturally triggered to flip to its flowering cycle around the time of the Summer Solstice, which falls between June 20-22nd each year.
- Water your clones with a diluted nutrient solution (400-600 parts per million or ppm) and place them under a low-intensity fluorescent fixture; T8 or T12 bulbs are ideal for this purpose, T5 bulbs are can cause plants to begin “stretching” before you are ready.
- Be sure to keep the cubes moist, but be careful not to allow standing water to accumulate in the tray. This will cause the rate of growth to slow, keeping them a manageable size and ensuring that some clones are not dwarfed by larger ones.
- As your clones begin to stretch, be sure to rearrange them to prevent some clones from being “shaded out,” and transplant them as soon as possible.
For the first week or two, be sure to check the moisture of the actual rockwool cube. In some cases, it is possible for the potting media to wick moisture away from the cube. In these cases, the potting media would be moist, but the cube may be too dry to support the plant. If this happens, pour about 1 cup of water onto the cube itself. Within two weeks the plant will develop a stronger root system, and this will not be an issue.
First, dig a small hole in the media about the size of the 1-gallon pot. Place the clone in the hole. The top of the cube should be level with the media. If the rockwool cube is exposed too much, it will dry out easily. If the media level is above the cube, it may come into contact with the stem. This can cause fungal disease. The stem of the clone should be as vertical as possible. Sometimes this means that the rockwool cube will need to be planted crooked. We find that having a vertical stem leads to superior growing results.
Next, fill in media around the clone’s cube. Be sure that the bottom and sides of the cube are in good contact with the media. The rockwool cube should be planted so that just the very top of the cube is exposed. If the cube becomes exposed through watering, gently pack some soil back around it. After several weeks, the clone will be well-rooted, and this will not be an issue.

The first step is to prepare the media you are planting the clone into. Some media may require soaking, conditioning, or some other form of preparation. Coco coir blocks, for example, need to be soaked and then broken up. Pre-mixed coco coir substrates are easy to work with and can be forgiving. Popular amendments include organic or synthetic fertilizer, oyster shell meal (for pH buffering), and various substances to improve soil structure.

Once you’ve successfully made all of your cuttings, dip them in your rooting gel and gently place them into a medium. If you’re using a rockwool cube, do not put the clone into the hole. Instead, use the cutting to pierce the cube. Doing so will ensure that no light hits the roots, and that the cutting gets maximum coverage.
Also pay close attention to a dispensary clone’s roots, size, and color. Clones should have visible roots on the surface of the medium. They should be no less than 4 inches, or 10.16 cm, in height, and preferably 6 to 8 inches, or 15.24 to 20.32 cm, with thick stems. They should also be bright or dark green with minimal yellow spots.

The only major downside to purchasing clones is the risk of incurring pests or molds. Most dispensaries carefully examine the clones they bring in for powdery mildew, as well as insects such as spider mites and root aphids, but it’s difficult to catch all of them. If you purchase clones from a dispensary, practice due diligence and double-check for pests before you bring the plants home. Be on the lookout for spider mites, as they’re increasingly resistant to organic pesticides.
For best results, put the clone in a wet paper towel, place in a resealable bag, and close the bag with some air left inside. Place the bag carefully in your fridge and replace the air inside the bag at least once a week. Do not put bags in the freezer. Placing cuttings in temperatures below 40°F means running the risk of bursting plant cell walls.
Prior to producing roots, clones require a high level of humidity. Place the cutting into a cloning dome and keep the humidity between 75-90% until their roots are capable of intaking water.
Dispensaries are typically the best place to purchase clones. Over time, dispensaries will become more sophisticated at identifying cultivars and ensuring plant legitimacy. Buying a clone from a dispensary usually means you’re going to get the plant you paid for, especially if you go to a source you already know and trust.
When you remove cuttings from the fridge, put the stems in water for about 30 minutes to warm them up. If your cuttings have been refrigerated for an extended period, they may take longer to root. To speed up the process, cut a half-inch, or 1.27 cm, off the stem, and dip the raw end in rooting gel when possible.
A cannabis clone is a prime example of asexual propagation — replicating a single parent plant outside the means of sexual reproduction. Cannabis clones typically start by taking a cutting of a stable mother plant, then providing the necessary conditions for the cutting to grow into a genetically identical plant.
