I just have a couple questions. First, I always see people switching grow boxes from veg. to flowering. Can't I just have a large growbox for both stages and elevate the plant during veg to get closer to the light? another question is lights, I want to grow about 2 maybe 3 plants at once each getting to about 3-4 feet. How many watts should i use. CFL lights. I also hear people talking about actual watts. When i look on a package i only see equivalent. Last but not least, smell. This is a BIG factor for me. Any tips. And what is a good starter strain with a low smell? Thank you.
