You're right leadmagnet and I've been thinking of grabbing one of those potentiometres (cool name) ever since I got setup. The one they sell at the hydro store is only around $15 but the problem is it's designed to be attached ti the fan, and mine is in the attic! Consequently I have to run it 20 feet, but even at this distance the space gets a little too cold when the temps are really low outside. I understand that big gaps in temp make plants really stretch, which is an issue in my setup. Definitely gonna consider these thermostats when I get around to tweaking things.

truepunk87 Looking awesome MCnasty. Ill be starting chronic around the middle of February. This has been great insight. Just a few questions. First, how would u rate the odor legal? And second, how long did u veg before u flowered?
thank you.
Odor: minimal. That being said I am running a very powerful fan. With that fan going I can't smell much. Once you open the closet door though a light smell does permeate the room, but once again it's not very noticeable and goes away quickly if I shut the closet door. It's only when I tamper with the plants that a sweet aroma eminates from the plants. I would definitely describe it as sweet and not skunky at all.

veg time: it wouldn't be accurate if I gave you a time because I ran into some issues during cloning which delayed plant growth. I think my rooting medium (AN Jump Start) is expired and doesn't seem to work very well so I experienced yellowing leaves that often withered away. I base my decision on the LENGTH of the roots. Once the roots reach a length of about 6-8" then they are ready. From the time I take the cuts this usually takes about 3 weeks. Or to describe it differently, once I see initial roots firming, I give it another 10-14 days. I bet if I got another bottle of jumpstart I could reduce this time by a week. I'll take pictures of my new clones when they are ready to go to give you a visual. They should be ready in about 7-10 days.

Some other notes: I'm going to be lowering EC levels for the remainder of the run. The range will be 1.6-1.8 instead of the 1.8-2.0 I've been doing. My gut says those dark leaves and curling are the result of over feeding.

More pics coming soon...
