For Hydro? I went to the nursery and this is what they showed me.. In a rush, I didn't notice it says "organic soil rejuvenator" It does have to be diluted in water... =[
i would say, soil and hydro are too different, but dont take that with a grain of salt hopefully someone will chime in... whats the NPK?
I thought that too.. and yea. i'm going to a bigger nursery right now to get actual hydro nutes. bastard at the smaller one basicaly just sold me some soil renewer or something
