Dude your shit looks great. If you can keep it between 5.8 and 6.0 your in there don't change what your doing. Hydro PH is on the low side soil is up about 7.5 . Rockwool sucks don't need it don't use it, causes rot but some like it and have good luck with it. There's a nute chart in the faq's that shows what nutes are picked up at what PH level.
LOC NAR1958 Reviewed by LOC NAR1958 on . aeroponic ph question i use an aeroflo36 that can be seen here... http://gallery.cannabis.com/index.php?cat=45139 what should the ph of the resevoir be in an aeroponic system. it seems to me that since the roots arent encased in rockwool but rather are suspended and misted that 5.8 is a bit low. i currently keep it at 6.0 since im unsure. any help would be sweet....thx friends Rating: 5
