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
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.
thx....yeah, i found that chart to be very interesting. so much so in fact that i printed it out and have it on the wall for easy reference :thumbsup:
I run my hydro 5.4-5.9 and my soil at 6.5-7.0...No higher than 7.0...that is the high side...above 7.0 and the ph level won't allow uptake of key nutes n-p-k...but also as LOCNAR stated...if they look good, leave them alone...It is good that you ask and don't take info for granted. I sometimes raise/lower ph in order to have plant uptake a particular nutrient; as slight changes in ph create optimum conditions for each nutrient...latewood

people - this guy latewood is SMART... sometimes you gotta break the ph rules to get adequate nuts to your ladies..
Garden ,latewood, Zandor. I would like to know half of what you all have forgotten. I'm learning. Maybe you guy's can get together for a book. But then you being here is worth way more. Thanks all you guy's.
thx fellas....its soooo nice to be in control of "the elements" rather than at the mercy of them. ive been growing outside since i was a kid
If you are worried about Ph then check out the chart of Ph availability in the FAQ.
Ph should very with the cycle from 5.2 up to 6.2 depending on how the plant responds.
