I have two plants that I have sprouted and grown for about a month, they are very healthy, very bushy, very nice root system and about 4" tall. They are in 2" rockwool in a 2" net cup. The hydro system they are in is aeroponic and DWC. They hang out with the clones so they have been on about 3% grow nutes and humboldt roots since birth. I am giving them to a friend who has the room to make them into permanent mothers. He keeps his mothers in Soil. Somehow he is a great grower but is mostly clueless about things he has never done, and while I read a lot, I am learning. So neither of us know the best way to transplant the girls to a soil medium for long term mother keeping. I do not know the details of his soil... but I imagine a trip to the hydro store wouldnt be a big deal. Thanks.
