I'd say that mostly depends on heat issues. What size is your cab? 800W might be a lot for a small cab.
canuck grower Reviewed by canuck grower on . Which one should I choose? I found a light system that has a 400watt HPS and 400watt MH together. Now should I buy this system or buy a 600W Hps for my flowering cab? For the money it cost the same as buying the 600 watter.:S5: Rating: 5
