I just do this grow for fun on the side. I don't have much space and I'm very limited in floor space and height. The base area of the DIY box is 50 x 60 cm and it is exactly 90 cm high. I would like to try to grow 4 Amnesia Haze Automatics in this box using cheap technology and without much effort. Because 90 cm is very little height, I try to keep the 4 plants small with the help of tiny pots and a scrog net and still get the maximum out of the 150 watt light from the Mars Hydro lamp. You can now see whether I succeed in this grow over the next few weeks. Have lots of fun with it!
