sweet. get that shit up and running bob. The Better homes and garden software is pretty sweet, it looks complicated, but if you watch the tutorial video, you see its not that tough. It is ment for building design ,so it makes it easy to do actual wall thickness and plan out your power and otherwiring and will even give a cost estimate on the job. you can easily find and download it from torrent sites. Just did a huge bud porn update on my log, you should swing by and check it out. Good luck on this build bob.
Lol, that shit sounds way above my skill level, but I appreciate the thought.
Below is a status update; sorry for the long-windedness and lack of pics.
As far as where we stand today (have pics but can't find the cord for my camera) - pretty impressed with the amount of progress I've made; the garage is pretty well all broken down (save for the veg tent), now just need to sell some of this shit to get it outta here (tents, ballasts, reflectors, trays, etc.).
Gonna run 4 600s stacked vertically around an El Blastido octagon, but with two more levels than he had.
Room is gonna be 12x8 and ~8' tall, +/- a few inches on all counts (housing both veg and flower areas).
Gonna crawl down into my crawlspace tomorrow and put a thermometer down there to get a temp check - been 90F+ for the last few weeks here, and I'm really, really set on being able to use airflow for cooling and dehumidification (as well as "heat" during the winter, when the garage can get down to 20F), as I'm not really looking to arouse any suspicion from the electric company and the AC, dehumidifier, and heater would burn about as much juice as the lights would, which isn't very efficient, in my eyes.
Hoping for a reading of ~65ish, which would just be fucking lovely, but realistically I could "manage" with a reading up to ~75 (I think).
Planning on having a 435CFM fan pulling from the crawlspace and then a 750CFM fan for exhaust from the 12x8 "enclosure" - gonna insulate THE FUCK outta the enclosure, and that fact coupled with the fact that I'll be exhausting air from the enclosure into the garage (hopefully bringing ambient garage temps down to around 85-90ish) should (again, hopefully) allow me to keep the enclosure <=80F during the day (lights off) and <=85F at night (lights on).
Of course, this depends on how cool the crawlspace can stay with me constantly pulling air from it, but there's a really isolated corner which I think would hold it's temp pretty well down there, so I've got my fingers crossed.
Worst comes to worse I'll just have to either 1) deal with temps higher than "optimal" for a few months a year, or 2) just not run during the summer.
BTW, I've searched the Internet far and wide and watched youtube construction videos for hours on end, and still don't have much of a clue as to how I'm gonna construct this insulated room - if anyone had a link or some good advice, I'm all ears.
