and even if you do the home vert with 3k vs 1k you will get a much better return on investment yield wise.. and if you own your home you only gotta build a good vert one time
ya he is the godfather of vert.. that setup is gonna do some WICKED numbers.. i am going to do a spinoff of that setup, but with an extra row or 2, a few more plants, and run 2k in it.. do another one right next to it and run em 4 weeks apart... sickness
