High temps in flower

Grow So High

Well-Known Member
Been experiencing higher than normal temps where I live and in return I’m sitting at 80-86 degree days with lights on in flower and about 75-82 light off. Growing with COB LEDs. Plants don’t seem to be stressed but are drinking a little more than usual as expected. I’m wondering is it possible to grow dense/frosty buds in this kinda heat? A lot of the threads I read all say expect slow growth, airy buds, fox tailing.

That extra drinking can lead to over feeding if you aren't careful. I think your temps are borderline manageable. My worst crop of the year is in the heat of the summer. I just try to run extra fans. I turned off a fan one day a month ago and forgot to turn it back on and had foxtails starting the next day.

2nd borderline manageable.
Keep them healthy if they drinking alot lower ppms on your feed and water more often
Try to up your ventilation and get some good air moving around.

This one is just sitting in a room with no climate control. The last week it’s been mid 80s at night and 90-100 daytime and around 30% rh. Little curling on the leaves but it’s doing way better than I expected.

People grow outdoor here and it’s average of 107 with 3-15% rh for July-August so they seem to be able to take some extreme conditions if you ease into it.

when you say your worst crop of the year is in the summer what qualities end up making it the worst? And what temps are we talking about

I’m in the same boat-I have 2 hygrometers in my tent, lower canopy is around 82°, top of the tent is around 85°, been that way most of my flower cycle so far. I turned my exhaust all the way up, added an extra clip fan or two, and have tried putting ice by my intake. So far no heat related issues that I can tell are going on.
Let’s just hope we don’t get too many heatwaves, I only have about a month left to go
