thats a good price TC,
cheapest Ive seen @HD is $46

they have many uses too...
along with checkin canopy temps I plan using it when i fire up the grill and make sure i'm locked on sear temps when the steaks go on

I am confused, I didnt read all the posts but are you running co2 at night?

Why are you getting a RH spike only at night?

Probably because during the day the ac runs thus taking humidity out of the air.

at lites out, plants dump the excess/unused Co2
so the Rh goes up and as Tc said with the ac not cooling as it does with lites on
Rh builds

it should have the efficiency of a walkin cooler, R-39.5 ceiling and R-40 walls
