Our premium clones are grown in 1.5 inch rockwool cubes. Rockwool is an ideal media for  because it has an excellent water-to-air content ratio that promotes  strong root growth. It is also an easy media to transplant into any  other media (soil, coco, rockwool slab, clay pellets, etc).


Your new clones should be planted as soon as you bring them home. However, in  some cases this is not practical. If you do need to store them  temporarily before transplanting we suggest the following.

Water  your clones with a dilute nutrient solution (400 to 600 ppm) and place  them under a low intensity  fluorescent fixture; T8 or T12 bulbs are  idea for this purpose, T5 bulbs are more intense and can cause plants to  begin “stretching” before you are ready. Be sure to keep the cubes  moist, but don’t allow standing water to accumulate in the tray. This  step will cause the rate of growth to slow, keeping them a manageable  size, and ensuring that some clones aren’t dwarfed because they are  shaded out by larger ones.

As your clones do begin to stretch be  sure to rearrange them to prevent some clones from being “shaded out”  and transplant them as soon as possible.


First Prepare your media. Some types of media 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.

Next,  Fill your pots with your chosen media. Fill to 1 inch from lip of pot  and gently tamp soil by pressing it down with your hand. By gently  tamping you help ensure that air pockets have not developed in the pot;  air pockets can dry out your roots and will negatively affect plant  health. After tamping you should have 1 1/2 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.


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


First, Dig a small well in the media about twice the size of the cube  (3 to 4 inches square). Place the clone  in well. The top of the cube  should be level with the media. If the rockwool cube is exposed to too  much air 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 enough rooted that  this will not be an issue.

Finally, thoroughly water in in your  newly transplanted clone. Thorough initial watering helps ensure there  are no air pockets or try spots in your media, and that the cube comes  into good contact with it.

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 irrigation  water onto the cube itself. Within two weeks the plant will develop a  stronger root system, and this will not be an issue.
