MY Shed-Log!

[NorCal Grown]

Thanks in advance for reading my log & all your input!!! If you checked out my other thread (Growroom Setup) I was planing on a wood 10'X14' shed, but I ended up building a 10'x8' metal shed. Built a OSB roof with the metal roof on top of that. The intire inside of the shed is rigid foam board with a R-value of 7.5/inch. So a total of 18.5 R-value. On the left hand side of the room is the main grow area, and on the left there is a table for cloning/seedlings and random stuff. Lighting is provided by a 1000w HPS/MH switchable with a 18" cooltube. Venting is a "Can-Fan" 6" Inline Fan going through a carbon filter before exiting the shed. I have all the little stuff, 16" wall mount oscillating fan, ph meter, temp/humid gauge, timers, sprayer. I'm debating to put up panda film or mylar, I have both but the mylar seems like a pain in the butt to work with. Any input? I tried to take pics of the room but my camera SUCKS, so sorry for the low quality pics.

So far I've sprouted Big Bud and White Rhino. I'm just doing a small grow this time to test the room out. There is 12 right now in 4"x4" pots, one BB is looking pretty sad, all others seem to be doing pretty good. They sprouted on July 10th and are under 4' fluorescent. How long before it's safe to put them under the 1000w MH? Planing on trying SOG next time, thats why I picked up the 1000w light.
