thanks for the updates! The fungus gnats are something you're likely to continually battle. I find them in almost all potting mix I've tried, from Miracle Grow, to organic, to more premium Fox Farm stuff. I'm sure there's some premium mix out there that is less likely to have it, but I've not encountered it yet.
As for the cold - for what it's worth, I didn't heat my garage this winter, as it's only half-insulated and the power bill last year was a bit crazy - and while the plants I have growing are definitely affected - they are still growing, fruiting, and producing. While I don't have a thermometer out there right now, I'd say it's been down to ~35-40 degrees at night when the lights are off. I just pulled a 195g tomato off one of the plants!
Obviously, if you are growing for production, you want ideal temps/humidity - but if you're growing to move a line along and get the next generation, I would say it's not as important. Temps can affect pollination of course, but I'm getting decent pollination even with the low temps. That's just my opinion anyhow.
