Temperature at night!

Me again lol.... Can anyone tell me what the best temperature is to have a grow room I have built in my shed.... I currently have a small oil rad on at night and goes of when the lights come on in the morning, the rad is around 20©...at night and around 25 in the day on the lights and fans.... Ps I'm just in budding stage.... Cheers

Depends on where (height wise) your metering it at..

Around 80F at canopy
75 at mid plant and high 60's for pot temps.

The trick is setting the thermostat height to hold that range.
OR
You fool with the temp settings at normal thermostat height to get the desired results

I find my best results, with the thermo at 72F and placed at normal thermo height.

In the fall/winter/spring. I bypass all cooling units and simply pull in the cold outside air (hepa filtered) by employing a greenhouse themo switch...
Electrical costs drop by about 72-75 %..

Night time temps should drop by 10 degree's F.... 15 if your promoting more coloring.

I gotta turn on the central and minisplits......ouch!

Used to use portables for backing up the central unit.....TOO COSTLY! Went right to minisplits and self installed. If you get interested in a Minisplit. Be sure you go with an inverter pump unit.

I’m in a shed also. 55f is what I’m keeping it at. It’s my outdoor grow, I waited to long to flower it so now I hooped. Next week is below zero C.
