oh and i've never done a strict test, but i've never really seen any difference using it for clones....but if you're not already using a something w/ B1 when transplanting, it def ought to help a lil
i use technaflora's thrive alive b-1 red and/or green when transplanting, its a 1-1-1 general purpose plus its got plenty of b1 to help w/ stress so its perfect for that purpose, as well as presoaking clone plugs or rockwool or whatever....it'll cost a lil more but i think it a much wiser investment than SuperT after i read that
