YOUR flower room temps..

Title says it all. Post up your flower room temps! I find it hard to believe that plants cannot handle 90+ degree temps...i mean they grow pretty well outside in 90+ degree temps - what's the difference between outdoor and indoor?

They difference is the amount of airflow. Even growing outside with high temps paired with high humidity, problems can occur. Obviously you can run high temps inside too with proper care.
My flowering room.temp changes throughout the year.
Winter On /off
72-75/55-60(that would be the low after not running for almost 12 hours)
Summer on/off
80-85/70-75

If I added air conditioning i could control my temperature to approximately where I wanted it.

Lights on 70, lights off 64-66. Growing in tent in a cold basement.

Your temps are way more stable than mine.
Im guessing my soil stays warm enough that it doesnt hurt too much. Keeping humidity dialed in is another story.

84/85 day
75/76 night

1300ppm CO2

78-79f lights on

69-70f lights off

keeping rh at 55% on/off but will begin lowering rh slowly over next few weeks.

Also in basement

I run in a cool bacement with COBs. I set it at 80f. I see temps up to 83f when the wood stove gets going. But never a issues. Nice dence buds. When I ran MH/hps I would see high 80s and sometimes low 90s. Had airy bud and heat stress problems.

I find if I get below 75f my growth rate slows a fair bit

72-75 on 68-70 off

Lights on 79 f lights off 71 f
sealed room 3 open reflectors

82f on, 76f off, I'm keeping my night temps up because the floor gets pretty cold.

A mass of soil that barely fluctuates outdoors compared to an indoor pot that rises and cools far too quickly.

Way more ir radiation outdoors makes for more robust transpiration system, adaptation.

Outdoors is plesant indoors most seem to have created wind tunnels.

There is no bottom of the pot outdoors, larger root mass better transpiration from exponetial growth.

Grow strains from hot countries, most are using hybrids for yeild not environment.

I guess theres a few reasons we off outdoor capabilities.

Still outdoors comes with bugs storms rain mold etc etc so theres always a trade off.

26C on, 16C off.

Saw a 34C (93,2F) yesterday and will see 35C or higher today.

In the same situation as yourself same winter temps. First time growing in the winter. What are you results like with those temps?

78-84 lights on. 65-70 lights off.

Are you using co2? Any heat related growth issues?
