How much big bud
Could someone tell me how much big bud to use with a twenty gal reservoir its my friends first time and he not sure thanks.
I dont go by how much per gallon. I use as much big bud powder to raise my ppm by 250. I always add it last. If i am shooting say for a target 1600 for the week i would mix my main nutes to 1350 then add my big bud to bring it to my target of 1600ppm. hope this helps.
If you are still in doubt, read the instructions on the jar...
You absolutely NEED a proper EC meter to dial in a hydroponics grow, especially running a regime that includes supplements!
