Pick a heat hearty stain. No Indicas and if hybrid go sativa heavy. Run your lights when it's night time and keep a fan on them their whole life. Just remember that weed is called weed because it's a weed lol the shit literally grows anywhere. Just watch your humidity in flower and you'll be okay. A few summers ago I ran some girls in my closet at around 97-108F every single day for 2 months then transplanted outside to 100+F every day through flower. One plant got a lil mold but other than that I pulled some damn good bud. Best in my area and sold it as such. I recommend sleestack skunk by seedman.

When it's hot, a plant transpires moisture to cool itself down. When your humidity is high, the plant doesn't have to transpire as much water, letting it deal with the heat much better. Therefore you should lower your nutrient strength, because your plant will be using more water than nutes.

Thanks for your response. Not sure I follow so I need to have a high humidity with the high temp? That's Probably what I've got its tropical weather.

Definitely not in flowering though, you will get fucked over with mold. I wouldn't even keep it high in veg, plants uptake most water through roots. Just don't let the pots dry out.

Vapor pressure deficit. Look it up.

I love when people talk about somethin they have no knowledge on.

Thanks bro. Where are you? I feel like the plants can take more heat in veg but not sure about flowering. Think I'm gonna get a dehumidifier too

If your growing in hear humidity isn't horrible and co2 and silica is Ur best bet to make it thru it with ehh results lol and if it's at 88 unless you have like 500 cfm running thru tube it'll still put off heat and put u mid 90's

No Indica's? So a landrace indica that's used to being growing in 90 degree weather or hotter would be bad......just a thought

I'm going to have to disagree on the indica part. It not uncommon for it to be in the 90's here during flower.

I've had many a indica and hybrids take it. Of course it is humid here to, so that may help.

I have had pure bred 16-20 week Sativa's handle several frost down in the 20's.

Not gonna happen without an a/c indoor. 90f isnt too bad with the lights on but 90f with the lights off is ridiculously hot indoor. Either run a sealed room setup or go outdoor with pheno's that can take the heat/humidity

Agreed my landrace Indica's always did better in the heat compared to Sativa's didn't like it as much and got way more stretchy than they should

Its weird. I can take a plant at 90+ indoor and it stress out. Same plant outdoors will be fine. I think if they are in the ground it cools the roots. I was thinking that in my basement, with pots on the cool concrete that the temps could be run a little higher.

It would also be effected by what type seed you were growing. Ibls or f7+, yea they are stable but not as resistant to pest, heat, cold, drought, etc.

F1's will have hybrid vigor and handle higher amounts of stress.
