For a step by step on how to ease your clones into direct sunlight, read our Hardening Off blog post.
Most clones are kept under 24 hours of light in nurseries, whether you are buying from a dispensary or direct from Dark Heart they are likely used to 24 hours of light, but most often the clones are kept under fluorescent or LED lighting and are not yet used to strong or powerful light/heat given off from the sun. Most clones are stored under 24 hours of artificial light in nurseries and dispensaries. When a clone is moved from 24 hours of artificial light directly into intense sunlight, it can experience shock.

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.
Next, fill your pots with your chosen media. Since it is essential that you have a developed rootball before transplanting into a larger pot, planter box, or direct ground space, it is recommended to first transplant into a 1-gallon pot. After a couple weeks your rootball should be developed, allowing to transplant her into a large vessel.
- 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.

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.
Pro Tip: Some growers reduce “transplant shock” to their clones by soaking them in a vitamin and hormone solution such as Super Thrive. Super Thrive and similar products contain vitamins and hormones that are reported to minimize stress on growing plants. Prepare a batch by mixing one gallon of water with ¼ teaspoon of concentrate. Soak clones for 15 minutes before transplanting.

Keep the room temperature slightly warm, above 20 Degrees Celsius (68 degrees Fahrenheit).
Continue spraying clones twice a day.
We have closed the dome vents again on Day 6 because we want extreme humidity now that clone roots are starting to show. Trapping the water in the tray with vents closed creates the best environment for roots to grow rapidly.
Using a new razor blade, cut the branch of the mother plant at a 45-degree angle. This “branch” will be your new clone!
2 small plastic buckets (or large mixing bowls – to be filled with water)
Place the dome back on the tray when done. It is best if you spray the clones in this way at least 2 times per day.
- Cloning Tray (with ridges at the bottom, no holes) & 7” Vented Dome
- Razor Blade or Exacto Knife & Scissors
- Cloning Gel and Cloning Powder
Note: Any brand rooting powder and gel will work for cloning
- 2 small plastic buckets (or large mixing bowls – to be filled with water)
- Spray Bottle/Mister
- “Jiffy 7” Compressed Peat Pellets(Recommended)
Note: Rockwool Cubes and Rapid Rooters can be substituted
- Grow Lights: Fluorescent Lights or Metal Halide lights (250w, 400w or 600w) seem to work best for cloning, however any quality grow light can be used.
Spray clones once in morning and once at night.
