Really struggling with heat this week as the country goes through a heatwave.. finally got extraction set up so was able to close the door and change to 20 hours. But it’s so warm, temps in the tent are getting too high for my comfort unless I turn the power of the light to around 50-60%! I’ve seen slightly slower growth than I hoped for, probably due to poor ventilation in early stages and slightly shorter days (16 hours) but over all I’m happy with results so far.
