Yes, I used Earth Juice Rootstock at 2 tbls per 1/2 gallon. Pre Mix and apply to rockwool, soaking it. Then hold it up and let it drop while holding it to shake out excess water. Most of the time I use just straight H2O
Thanks for dropping in and asking. I'm not doing as well as I could, I'm sort of feeling hopeless at this point due to the problem of not having a local Co-Op dispensary within 150 miles of my home. All of the somewhat local Co-Ops closed their doors in 2007 because of DEA raids but I recently heard that there may be a couple of places opening soon but thats stll a 210 mile round trip for me. I hope all is well with you and thanks again my friend.
