ranger that is how I am going to re-design things. I'm running 18/6 in the veg room so I'll push it to 24 and maybe that will help. When I rebuild I will put both rooms inside the same larger room, and each one is going to be sheetrocked and sealed. Then I can set up air and heat systems and be able to control things better. Right now the flower room pulls air from the veg room, which is actually in an adjacent room of my basement, and the air leaks in via spaces around central heating ductwork along the ceiling. The adjacent room where the veg is set up is actually my laundry room, and because of it's orientation in the house plan, receives little heat from the rest of the building. Definitely not ideal. But at the moment it's what I have to work with. Once theses two batches of flowers are done, I'm dismantling everything and re-building properly. When I move the current batch in veg to the flower room, I can shut down the MH in the veg room, so the flower room will be pulling cooler air. Also I may let the plants sit under the HPS for a couple of weeks to help put on some healthier growth.
