what kind of nuts are you using?

I'm new to hydro and just received a couple of clone in rock-wool and have them in a bucketeer dwc system. they seem to be growing great with some superthrive and kelp, but i was wondering what others use.

the pics attached are the roots when i first got them and the second are the roots after a couple of days of just super thrive.

also, please tell me where you got them(if you don't mind)

Them some nice roots there..I've got 3- 12" bubblegum clones going.I use GH Flora series, seems foolproof, little odor, not much salt buildup.I get them from discount hydro.com..best to you..

thanks. good luck to you to
