Are you going hydro or soil, i havent heard of a hempy box... Though im kinda new compared to these other guys. what i would do if you never grown before, is grow some plants traditionally then probably half way through, figure out how everything is going and get the basics down, then start that hempy box thing. also you really only need 2 bottles n pull it off Grow Big and Bloom, I wouldnt mix nutes, some have other chemicals in it that will cancel on another out, stick with one brand before you start buy a series of brands, get a successful grow or two under your belt before you go about doing the more advance stuff. also more pictures go along ways, the more pics you put up the more hits you'll get, people love pictures on this site. Message me back let me know whats up after reading this
