So the strains I'm growing are white rhino and purple haze. Now I'm gonna be growing in a cardboard box with 6 23 watts cfls. A 6 inch online fan taking my air out and I have 2 vent holes at the bottom to bring in fresh air. Now my mesurements of the box for now are 17 5/8 inches long x 26 1/2 inches tall x 13 inches wide. Now I have done a semi box grow before but this is going to be out of the reach of my dog and it's gonna be placed in my boiler room. Now were my concerns are is I know purple haze grows tall but I want to try it in my box. Now I know I'm going to have to mod my box a bit as the life cycle goes on in the plants life cycle. So were I'm stuck at is can I keep the plant short by L.S.T. To make it more bushy then tall? Also if anyone has grown P.h. Indoors what was the hieght that you grew in to. Also a thought about scrog for it inside the box would that work to keep the hieght down while I also double my yeild? I will post picks soon. Thanks for the info from one green thumb to the other.
