They’ll be okay? High temperatures

rfzhrstarted grow question 5 years ago

I have little problem with temperature in my growroom. My ladies are on the end of 6 week. One is a lot bigger than other. But they both are Think Different. Temp is on 32*C and sometimes they have even more temperatures. Humidity 42-50%. Can’t fit in ac. They’ll be okay

When I struggled last year with my high temps. I bought an evaporative cooler and had it outside the tent blowing through the mesh screen on one side. Really helped 👌👍🌱but any higher than 32c is going to cause troubles with most strains.

Thanks Fruitgrower for answer. This evaporative cooler doesn’t need to have cooler water all the time to function properly?

I forgot to mention. Once they’ve had temp over 45*C! After that they’ve showed that burned tips of flowers and they looked a bit shocked for some time. It was about week ago and now they look healed up and used to this extremal temperatures but it’s my 1’st grow and i don’t have enough experience to confirm that
