I started off with 5 plants and vegetated for about 5 weeks. 4 became males. So this one female got a whole 12 gallons of dirt to herself. I started my plants under T12 fluorescent lights, then moved to a 400-watt HPS system about a week before I switched to 12/12.

It's in my attic, and temperatures are typically around 90 degrees. I have a 50 cfm bathroom fan providing ventilation, hooked up to a thermostat that's set to turn it on if the temperature hits 90 degrees. I walled off part of the attic and insulated the ceiling there, which helps keep the temperature from shooting up too much during the middle of the day. I'm sure it'll come in useful during the winter too.

I have a whole bunch of fungus gnats and thrips. Garden-Safe spray doesn't seem to do much, but maybe it'd be a lot worse if I didn't use it. I have my lights on at night, which has the unfortunate effect of attracting bugs through my vent. Still, they don't seem to have had too much of an effect on my plant.

I did top the plant during flowering, and the side shoots grew out very well. I only have 68 inches of space in my attic, so I need my plant to be nice and bushy. There's like 20 heads on this thing!
