Hey I have a 600 watt hps n a closet grow whole closet is 4x4x7 but my flower area is only 4x2x5 the 600 watt is in my flower area right now I run it at 75 percent which would be 450 watt iv had it for a couple weeks and my plants are showing signs of light bleeching so I moved the light as high as it could go next week I'm getting a carbon filter and i want to completley seal off my light from my grow room taking cool air in from outside the room threw the light and then threw the carbon filter out of the room and then have the room sealed and start using a co2 bag called exhale I have a couple questions question 1 will having a co2 bag in the room help stop the light bleeching? I want to run my light at 100 percent and question 2 will having my carbon filter hooked up to my light even work if its sealed off from the room? It will still be in the general closet any input will be much appreciated
