90 degrees to hot for a plant?

No, but I wouldn't let it get much higher. Outdoor temps commonly hit above 90 and plants thrive, not a big deal but again, I'd take care to not let it get much higher.

ive read on the internet that if temps get about 85 that it will effect the density of your final product. not sure if its true just throwin it out there

i agree that 90° is too hot. in the summer, on real hot days, my grow room gets up 93° and some plants start to curl and claw pretty bad. ive also had lighter, airy buds with temps that high.

90 degrees is fine, not ideal, but fine. frmrboi is a terrible troll.

Make sure when running at high heats to provide propper quantities of fresh air and plenty of air movement.

opinions are like assholes everyones got one, most of them stink.
guess what this guys opinion does ?
Photosynthesis stops above 85 degrees... Really?

Stoma open at 85 degrees... Persperation increases... Can cause molding if not well vented and limbs tend to be more flacid as the hydrostatic balance is temporarily off kilter...

Photosynthesis does not stop, thats just sillyness. Lack of water and extreme low temps can cause stoma to close which impedes the rate of photosynthesis but you cant tell me that plants don't grow around the equator.

If possible add c02 and your plants will actually benefit from the increase in heat. Metabolic funtions will greatly increase in speed.

Nutrients are all preference. I grow organically - i can offer some info on that (you will see diminished yield growing organically and it is a bit more work). Farmers use cheap generics and think about it, all they care about is profit so they go with whatever is most cost effective. If you want to get all crazy and spend alot more go hit up a hydro store and they will load you up with an entire line for a few hundred dollars.

If you want to keep it cheap go to your local garden store, walmart, homedepot... and find some cheap high nitrogen chemical fertilizer for veg and some high phosphorous with alil potasium fert for flowering.

Over 90 F is DEFINITELY a problem indoors!!!
I bet you almost anything that in about ten days you'll start finding BANANAS and inner-sexed flowers coming out the sides of your bud.
It effects the plant almost like a light leak would.
Not good.

Why would heat indoors effect differ from heat outdoors? Sudden heat fluctuations is one thing but if its always hot its always hot. I grew in a closet that averaged above 100 for at least a month and had no herming. My greenhouse veggies grow faster in 90 degree temps than my outdoor veggies at 75 as well.

Again - not saying to aim for high but 85-90 really isn't much to worry about as long as it isn't going to climb.

don't waste your time, the dudes got a man crush on the 'tanker.

Years of trolling and I have yet to see a single plant you have raised.


I don't know enough about your situation to talk aboutpropper lighting. Small area with high temps? Go with floros. CFLs work wonders. 23w are cheap and the 68 throw far enough to not require daily adjustments. 2700 for flowering and 5500-6200 for veg.
