whats your ph??? and whats your rez temp? i hope like 65 degrees and it never gets higher then 75

well i lost the test strips for some reason but its normally always at 6.5 with no additives in it. my res shouldnt get that warm i mean the grow area doesnt even get much hotter that that.

so what is your rez temp?

ok so i extracted one because it turned male on me. now it is in a bubbleponics system how do i get the dead roots out that are all notted up with the other plants with out damageing them

hahahaa has best has you can....

well the roots were too intangled with the other so i found were tthe problem and just cout out a few inches off of the healthy one but i think it will be better off than root rot
