Hey all. Realize this thread is a bit old, but I read older posts as I'm sure others do, and I just had to chime in and let people know that CNS17 grow hydro and yes, it is white and creamy, like melted ice cream, but it mixes JUST FINE in water, GROWS GREAT, is economical (that's probably why they have a prob-AN has people believing you have to spend a fortune to get good results!), and it's from Botanicare, which speaks volumes in reputation. So, if white turns you off or you just hate having extra $$, then go on and buy the expensive stuff. Myself, I'm spending my extra cash on upgrades!
