@Shuggz they will want more water, the bigger they get. So there’s that.
They like a higher humidity while in Veg and lower in flower but 40 is a bit low, but if thats all you can get, then short of adding a humidifier…
25-27 degrees is optimal but 22 is ok I would think. I usually try to run my tent at 24
And you’re welcome and same to you!
