really GT?
i think it is a bad idea to use powder products in an aero system.
I wouldnt advise using any powder thru a sprayer nozzle even if you dilute it with warm water or whatever, it would work to root the clones, yes, but if you do it, be sure to check the nozzles every day to see if they are clogged shut.
Just my thoughts, I actually use aero and DWC, found that all that paranah stuff and etc is not good in powder form and will cause problems somewhere down the road unless you are OCD about cleaning but then I don't know how good cleaning products are on your plants roots, and if you are going to but cleaning products you mite as well order the liquid clonex online.
Also, Asprin has a lot of the active ingredients as the cloning powders, it is dirived from the willow tree. PM me, I could scan u a good artice from a mag i have if you want to know more.
