Scandinavia

@BunnyBud, Thanks for the tips, i will diffently try that cold damp towel method! And I have same problem with the temps, but thank God it will soon get way colder outside especially where im at :D I will be following you too and for sure learn!

@Scandinavia, great job man! :ok_hand: I’m testing some “low-tech” tricks myself: I use an ultrasonic humidifier which already drops the temp by about 1–2°C just by pushing out that cool mist. On top of that, I placed a folded, really damp towel inside the box near the pot — it helps me keep humidity more stable (so I can run the humidifier at low or half power even on the worst days), and it also adds some evaporative cooling that brings temps down a bit more. Right now I keep the windows open, and temps outside are around 28°C, sometimes hitting 30. I’ve turned off all the AC units because I wanted to see how far I could go just with these methods. So far I’m managing to keep my box at around 27.5–28°C, while my room itself stays between 26–27°C. With good air exchange you can really do a lot, and of course a bigger grow space makes heat dissipation way easier. I’m starting to “read” the parameters day by day — I can already tell how the box will react depending on the weather outside, and that helps me keep things as stable as possible. When winter comes it’ll be a whole different story: heat won’t be the issue anymore, but humidity control will become the main challenge. That said, I’m really glad I found someone like you here. Hope we can share tips and become good grow buddies! :seedling::fire:
