"THE SEALED ROOM" 3lbs A LIGHT

[Tranoble]

I use polly cause the shaders I use dont shine any light on the walls only on the growing surface.

The Co2 does make up for the external air. I have no air coming in from outside and I have no air going outside from my room. This is why I have to use Co2 and I can get the best production out of my plants.

I use only HPS. I managed the biggest hydroponic store in Canada for about 6 years and thats the first time I have ever heard HPS bulbs making your buds long and fluffy. My buds are long and rock hard. I allso drop my temps as cold as I can in the last 2 weeks that helps to harden my buds.

I love yr set up its really really nice.

Why did you choose just the polly rather than some mylar ontop?

Does the CO2 make up for an external air source?

Why not 2 1 ratio MH to HPS, HPS alone has tendancy to make long fluffy buds?
