Okay.

Any light's gonna be better than nothing.

But a "veg spectrum" is whatcha want, if possible.

5500-6500K (bluish-white) color temp: daylight, bright white, cool white, etc. etc.

You want a nasty, harsh looking glare on dem plants right now. (The soft, golden "warm whites" are better for flower.)

I'd get as many lights as I could on the plants, even for a day.

I would NOT heat an 80 deg F res. Lotta the anti-crud formulations tell you to up the dose in a res that's over ~74 degrees, as if that's a magic number for increased bacterial growth. Lotsa folks run 'em real cold. S'posta have lotsa problems if you don't.

Maybe someone here can give you ideal temps for your exact system. IDK, sorry. Hermie
