Maximum temp

Hello all,

What is the maximum temp that cannabis can grow? I know that ideal is about 80 degree's, but what is the maximum temp that it can still grow? For instances if you only had a choice of growing in a spot that during the day times will some times reach 95- 100 degree's....... Is it still possible? (i searched first)

Thank you everyone.......

Its possible, i would stick to Sativa strains, they originated near the equator and are more heat resistant.

A humidity and temperature gauge are essential in any growroom. Daytime conditions should be 70-80 degrees without co2, 80-90 degrees with co2 until the last two weeks when daytime temps should be kept between 70-80 and co2 can be reduced to adjust for the lower metabolism. Night temperatures should be kept above 60 degrees to prevent stress. It is preferrable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation.

anyone else?

Did you specifically mean outdoors?

if is it a grow room you got a little stress source there but if you are outdoors you just have to watch to get a strain that can take a bit more heat, sativa heavy strains usually like a bit more and don't heat up as much as the bushy indica strains

If it's outdoors you can use shade/shade clothe to help. This alone will make a huge difference because it it cutting the direct light off and only allowing indirect light.

It's indoors, the only place that i can find to grow is a area that during the day will reach 90's to possibly 100's, during the night time i can get it down to 80 degree's tho. I know that this isn't the ideal climate to grow, im just asking if it is possible at all?

Thanks for the response's

Indoors way too hot.

AC units are now crazy cheap. $100 for small areas. $250 for huge areas. and that's for new units.

marijuana is a weed and is a very resistant plant. I know it can grow in 100 F although it is not the ideal temperature for it. All it needs are the basics. Sun water nutrients and it will thrive!

Its possible definately but I wouldnt let a room get that hot.
