HEyo, i need a new light because cfls are not working for me. My space is a fridge a normal single fridge. so its like (0.5x0.4x0.8)m i have and extraction fan thats pretty strong 350m cubed. the room temp is usually 15-20c. I'm looking at a 250w hps or a 400w for £5 more and its getting the frugal fuck in me confused. more light = better yields right. but more heat = worse yields. i reckon i could make a cooled hood. but i am really tied between the two. i currently have 4 150w photography cfls (a moronic thing to do if anyone is thing of doing it) and they heat up the fridge to around 26 - 30c depending on the room temp. What should I do?
