I understand what you are saying, but easier said than done. Have a lot of expenses coming up. And hps is the best that I can afford at the moment. I just have to except that I will be buying.more down the road, and that is ok. We are talking 2-300 vs $70. As far as heat. Being winter and I have my tent in a corner next to a window that gets very cold, I could actually use the extra heat, heat is not an issue. Also I plan on Scroging my next grow, so will only be using about 3 ft of grow height anyway.
