You need to introduce your clones to sunlight (after transplant) in a gradual, slow manner. Starting with partial shade and indirect sunlight will be beneficial for the first few days. The partial sun will get them invigorated to grow and the shade will ensure the heat is not so strong that they are overwhelmed and go into shock.
Cannabis clones go through two cycles in their lifetime: the vegetative cycle and the flowering cycle. During the vegetative cycle, a plant is doing the majority of its root and foliage growth and should be receiving roughly 18 hours of light and 6 hours of darkness each day. If clones are not kept in the vegetative grow state long enough this can cause something called pre-flowering. Cannabis plants are photosensitive, meaning they will flower if they receive too much darkness, which can also cause a plant to stress (hermaphrodite: produce seeds). It is important to keep a close eye on the plants in this early stage of life and to watch for signs of heat stress such as drooping or curling leaves. If they do show signs of stress give them a break and move them back to the shade. It is wise to continue to give supplemental lighting through the dark cycle of the day ensuring they do not receive more than 10 hours of darkness.

Finally, thoroughly water your clone. Thorough initial watering helps ensure there are no air pockets or dry spots in your media so that the cube comes into good contact with the water.
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.
Fill to 1 inch from the tip of pot and gently tamp soil by pressing it down with your hand. This helps ensure that air pockets do not develop; these can dry out your roots and will negatively affect plant health. After tamping, you should have 1 ½ to 2 inches of space between the lip of the pot and the media. This space is important so that you do not overflow the pot while watering.

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.

Adding water over the top of stems now will make it take longer for clones to root. Do not add water to the tops of your pellets!
Next, we soak the Jiffy 7 compressed peat pellets in the warm water, which makes the pellets expand in size, as pictured below.
If the Rockwool or Peat Pellets are dry to the touch we will add half a liter (
This way the fan leaves will still remain and speed up the growth of the new cannabis clone.
This photo shows the difference between a small cannabis clone vs a big clone. You will get faster growing and more vibrant plants by choosing big clones!
Remove the clear plastic dome from the cloning tray and spray the clones and inside of the dome with water.
Remove the dome on the cloning tray today to allow clones a chance to adjust to normal humidity. Clones may be transplanted to dirt or Rockwool anytime when you see roots.
The next step is to spray the clones with water before moving the clones under the light.
