Some of the newest LEDs are totally modular, and their University tests are pretty impressive as well. When you think about the fact that the average HPS last about 18 months max before replacement, burns 3x the wattage for near equal "PAR" value, produces a lot of waste heat, penetration is a good thing but not so absolutlely required in a SOG set up. Just put those 3W 60 degree LEDs right on top of em and watch em grow. Just my opinion, everybody's got one. Good Luck
williboy Reviewed by williboy on . Several LED'S vs. MH + HPS Together? Alright, so I plan on building a decent sized grow room. Planning on spending around $15k for lights, CO2, air conditioner, etc. One of the biggest things I keep researching and going over in my head is the types of lights to use. I first thought of just using a couple 1,000w HPS's, then I thought of mixing a 1,000w MH with mayyybe 2 1,000w HPS's. Now I'm reading more about LED's and they seem to have a lot going for them as well. A few things will possibly factor into helping with my Rating: 5
