highangle you're making me blush.
Thanks for the lighting input, I was incorrect in thinking fluorescent ran the coolest.
CO2 would be great but currently this space is just too warm, unsealed. If I sealed it it would be much worse obviously. And I type this about 15 feet away from a 20 lb tank of CO2 I have for a planted aquarium. The temptation is certainly there but not in this current space.
Yes VPD will be on my radar as I add more circulation and eventually AC.
Happy Friday all
