Im sure somewhere this has been asked...but I cant seem to put the right words together to bring up an answer. Just a quick question...is there any harm in growing 2 different strains in the same rez in DWC? Can the roots from 2 different strains coexist side by side? Any harm if they (the roots) intertwine a little or do i need to create some kind of partition in the middle of the rez? Strains = Pineapple Express and Vanilla Kush, 8 gallon reservoir (14 gallon tub)
