If you can the best way to do it is to pickup a variable watt digital balast like the Galaxy so that you can vary the wattage depending on ventilation and heat issues. During the winter I use a 1000 watt, but during the summer I step down to a 400 watt because of heat issues. Not much change in finished product other than the 400 takes about 2 weeks longer to finish than when under the 1000.
killerweed420 Reviewed by killerweed420 on . 4X4 room, I was told I need 800 watts? Is that right. I've been doing some browsing online and found some websites that suggest that my room (4X4X8) would require a minimum of 800 watts HPS/MH lighting setup. Do you think thats right? I can get a lighting system that includes everything for $250.00. Is that price, high or low... Any help is greatly appreciated. Rating: 5
