Low/mid 50's on far side of room, 62F at the plant table and using an I/R gauge creatively gets me around 70 at the plant. Dirt is 63-75 across all my plants depending on location under the light. No exhaust fan running at all but intake still on. Lights out is 12pm - 6pm. These are just good guesses of what I saw this morning and middle of night I don't have my logs here.

I think a lot of my problem is the size of the room. I should have paid attention and boxed it up to begin with.
LAmike Reviewed by LAmike on . Growing in Southern Cali, pointers from locals? I am having a hard time balancing temps still. I don't like drastic temp changes. What are others doing to maintain temp in the Southland? It is easier with the 1000w HPS bulb. Room 12'x16' (Will enclose smaller after harvest) Cooltube (Duct to attic is completely off right now to maintain temp) 1000W MH conversion bulb for HPS socket. (Runs really cool) Box Fan in window with an A/C vent to block the light. Minimal actual pull from box fan maybe 200CFM makes it through. House Central Rating: 5
