I've absolutely no idea... why not ask someone who's grown using hydro? This is my first ever grow using soil and my first choice was shiva seeds... i may try others later but for now it seemed to fit my conditions perfectly. I would advise reading up on what seeds suit the conditions you're growing in, other than that I can't advise you on something I know nothing about... sorry!I am about to start growing hydro for the first time what straind should i use, i have about 13 diffrent brands 3 or which have no names. which schould i start out w/? Skunk Red Hair, Auraura Indica, Skunk#1, White Rhino femanized, White Widow, Purple Haze femanized, Ice, Cyrstal, Shiva Skunk
