I have my small space loaded trying to get everything tuned in before plants go in, I will say if you have the cheap digital hygrometer/thermometer like an acurite or something don't sit it directly in the light or you will pull your hair out thinkin your room is wayyyy to hot, in general those seem to reed a few degrees higher, I recommend the aquarium style thermometers in conjunction with a good ol' analog hung somewhere in the shade and a digital one in the shade/out of direct light as well,
Here's the aquarium style ones, I highly recommend these, I use them in all my Rezs and also it's very accurate for canopy as its not effected by the direct light, I just hang mine over my ducting for my air cooled lights
Yeah I mainly just use those aquarium style ones for my res temps or root chamber just because I don't need to lift any lids or anything but every time I step in my room I act like I'm shooting my plants that's where the "more fun than anything" came from lol, but it's cool to see what each plant is comfortably sitting at,
Ps fun trick, not sure if you have tried this but one night after you smoke one get it and go outside and point it at the moon lol, it reads in the negatives it's funny
