I have always grown outside, in very hot weather, sometimes 90s and above. My plants did very well in those temps. I am now doing my 1st indoor grow. Here is a pic of one@ 8 days. I havent had any problems but I bought a Digital Temp&Hum. thingy, set it in my growbox( small Fridge) and just checked,,, temps at 91, Hum at 34. Is that about normal. I coulda swore I read that temps should be at 80 or below.And of course it didnt make since to me because of my outdoor grows being fine with those temps. They seem to be very healthy.
