Hey everyone im about ready to start my first grow its in a space of about 2 foot by 2 foot by 6 foot high, would i be best using 250 watts of hid lighting or cfl? the reason being that ventilation is a problem i have ducting but it runs from my wardrobe into my room and heat just tends to keep building up. Do 250 watt hps/mh throw out much heat? any ideas?
