@vostok @Cold$moke I think it was one you you that posted this video once upon a time. Have you guys ever seen other people trying this? Think you would have to treat or clean the batting before using it on the plants? Also maybe it could be used as a cover layer on top to prevent moisture loss and mold/bugs? I have clones rooting and IL be doing a 3 way experiment with run to waste coco in 2 gal plastic square pots, and 2 gal fabric pots and then the polyfill root layer. All with plastic over the trays. What do you think? And do you have any suggestions to do this experiment better?
