Till now I've made a totally beginner grow with 8 CFL lights and without any grow box and it was a successful grow. Now I'd like to upgrade things a little bit and actually make a grow box and also use HID (HPS/MH) light. I plan on growing 2-3 plants and I thought of creating a box using these measurments: Width 4' x depth 2' x height 5'. I'd use 250 Watt HPS/MH lamp. What do you think of it? Would you change anything?
Would work, the one i built is 60h 24w and 20d and i can do 2 dwc in there easy, With MH/HID make sure you have efficient exhaust mine has LED in it and top of the box still gets around 80
