Heat query

Hi
My flowering shed is at a steady 20 degrees Celsius/68 degrees Fahrenheit during the light on period is this ok. it drops a little from this during the lights of period. It's hard to get the temp any higher, at the same ensuring there is good air flow.

Is this temp ok? my humidity is sitting around 50%

What kind of light do you have? Cool tube/some sort of air vented hood?

400 hps with acool tube and electronic controller which controls the in and out air flow.

You need that heat in your growroom. I've got my vent fan plugged into a thermostatic outlet for winter temps...

my grow room is usually at 70-75 f. 68 isn't too cold. certainly, a few more degrees would be beneficial. Humidity is just fine... anything over 60-65, start getting a bit concerned.

I envy you.

Does this have a negative effect on the plants if the vent fan goes off, and then no new air is introduced until the temps pick up and fan kicks on again/
