Whats the ideal temperature?

22C is a nice temperature, like middle of spring or the beginning of summer, plants thrive in that time of the year! You should also consider to check humidity, it’s important as temperature itself. 75% when the plant is young, 55% when flowering. This is a generalization but it will work in your case! Cheers

Vapor pressure deficit chart

You need a VPD chart. There is one i nmy main gd profile. look down near bottom in comments section. it is an image hosted on growdiaries, so no offsite. What is optimal is relative to temp and humidity (pressure too, but we can assume 1 atm give or take a small a mount) The phase it is in matters too... Check the chart out or google it for one.. believe it is from Perfect Grower. You can find many and they should all give the same values relative to any rounding errors invovled.

Hey that’s a good temp. After 3 weeks I try and get the night temps a little cooler around 18/19 and then day time temps 23/25. Good job Happy growing
