hmmmm for that size of a space why not grow with a 400watt, not as hot and is suitable for the amout of space. also, getting greater yeilds depends on ventilation, so adding a bigger light might contribute to a harder yeild........my 2 cents, good luck
keeko Reviewed by keeko on . 600W in a C-22??? A good friend grows in the model C-22 closets (2x4 ft) using 400W MH & HPS. Realizing that more wattage equals greater yields he wants to go to 600W systems all around. But, he says that he will not be able to control the heat. I say that he will be able to do so with proper cooling and venting. What do you guys think? Can a C-22 support a 600W system? What other factors must be considered? Rating: 5
