I'm about two months into my third indoor grow.
#1 was in my moms basement (no shit) in 1984. My biggest baby was bushy as crazy, I was all about the FIM, a couple others I did some weird training to. She nabbed me LOL and shipped my ass off to the Army.
#2 was maybe 10-11 years ago in our semi-finished basement. 2x "streetlights" from lowes, screwed to a 10" x 50"(?) plank, with a radiused & flat whited piece of 3' long 6" stove pipe. Crude but servicible, and got compromised in mid-flower by wifes 13yo daughter... so I shut it down and unloaded any trace of anything, just a white-painted 6' x 5.5' block-wall room.
#3 I "broke ground" in March 2012, with intent to refit that one room with new & better kit... But then I started doing numbers, and decided to build another small room adjacent. So now we have a 6' x 3.5' grow room and a 6' x 5.5' bloom room, both with 1000w Lumatek dimmable ballasts, sealed/air-cooled lamps, CO2 & digital timers, dehumidifiers, and large 6" carbon filters. Here's my build-out thread if anyone cares:

The girls are into their 9th week from seed (4th week of flower) now... all looking good to my pretty newbie eyes. I'm using this one as a refresher course... nearly killed them all in wk 2 with some whacky-harsh homebrew soilless mix
I recovered and they are standing in 7 gallons of Promix BX and seem happy with Fox Farms Tiger Bloom & Big Bloom feedings.
