if you already have the cfls then do both
gt420z Reviewed by gt420z on . Looking for a COMPLETE 50Watt HPS system. I am starting a grow soon. I'm not new to growing but this is only my second time growing indoors. My first was with only about 150watts of CFL. I was quite suprised at the yield but it seemed like such a waste for the effort and time. So I figured I'd step it up a little and get a HOT5 setup. So, I have a 4ft HOT5 fixture mounted and ready to go. This fixture has a mixture of 3000K bulbs and 6500K. A total of 20,000Lumen. Then I got to thinking, I'm sure it would produce a great yield by Rating: 5
