You can now find in your trusted online Growshop, the Cultilene Rock Wool Block with a size of 75 x 75 x 65 mm. These tacos will be useful, when you have already rooted your plant in a smaller rock wool block, and then later you transplant to this larger one, adding a root additive, to increase the growth of the roots, using a good amount of water.
When you have finished the process, you will be able to transplant from this rock wool block to a pot with clay balls, or any other hydroponic cultivation system that you are using.
It is very important to bear in mind that before using the rock wool, you must regulate its PH allowing it to soak in water for 24-48 hours.
Buy the rock wool taco from Cultilene, in PevGrow, and increase the root growth of your cannabis plants, to achieve greater growth and therefore a greater collection of buds.
