if its just for flowering i would use the extra watts used in the mh for more hps.
JackdaWack Reviewed by JackdaWack 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
