I can't figure this out and I'm forced to start my first grow op later next week. How much nut should i buy to get me through on grow season and which do you recommend?
 
dont really know man, how often are you going to change out? I would get a gallon of grow, a gallon of flower,bottle of flora nectar, quart of cal-mag, GH compost tea, ph up and down, and superthrive.
