I am setting up for a first grow and have some concerns over lighting. I was going to grow in a 2x2 space using CFL lights. After a ton of reading here I am not sure. I am not sure CFL is the best way to go. Will HTGSupply 150 watt High Pressure Sodium Grow Light handle the full 2x2 area. If so, will it produce as much yield as 16 24w cfl in the same area. It would be 1/2 the actual watts at the 16 bulbs. Since watts measure heat, it would be cooler and penitrate deeper. I am just not sure best way to go. I dont want to jump to a 250w HID yet.
