For those that disagree with root trimming... I get it.. totally understand.. but my 1st hand experience is that, trimming 1/3 of the root mass (which really only turns out to be the long wispys) helps in a couple different ways.. 1st is that it help keep my RDWC clean and unclogged. 2 is that it promotes more uniform root growth.. and 3.. well shit I really got nothing else lol I'm fried right now . All I can say is everytime I trim up the roots these ladies go ape shit and shoot up 3 inches over night
