Yup. My understanding is that anything over 85 degrees (F) in terms of your leaf temperature and the plant becomes unable to breath and process properly. I don't run CO2, so 85 degrees is my cut off no matter how warm I want it in a particular stage. When I open the tent and once in a while the AC went out overnight or whatever and the girls are at 88 degrees and the arrow on the gauge is pointing up, I always freak. Lmao.
That said, there's a caveat to that. As we all know and see every year, there are many summer days when it's hotter than 85 outside for multiple days in a row, and often the plants don't seem to mind at all. If it's 90 for a week straight you can bet the leaf temps are all way over 85. The plant was given to us in a very resilient state of being, and they'll handle a ton more than we would ever give them voluntarily. I think maybe the question is not so much one of "can they take it?" as it is "how long can they take it before we start to run into problems?"
Tropics where plant is from hotter than that summer time it's like 100 in Columbia
I keep mine around 75 to 88 all the time. 75 at night and 82 during day. Which I seen 88 many times on the temp
I know, see my next post about that. I think this temp thing is much more important in a tent grow. We would never let our plants get into the 90s in a tent. You know? But outdoors they don't seem to mind at all most of the time.
I'll let mine get above 85 a little bit if I have a ton of air flow and I want a warmer veg. I wasn't suggesting it's a set in stone thing, just what my understanding was. I thought if you wanted to run hotter than 85 you had to use CO2. In a tent/indoor grow.
I don't. Just got fan in the tent no ac at all. Not going to. I try to keep it like natural way I can humidity high like Columbia.. it's hot as hell and humid as hell there.. so idk what therapy is but that's way I think. Most places like that has the plants grow wild there.. sure don't grow anywhere else naturally
Today was about 27C, the next 10 days is forecast to drop down to 23C. Around mid April when I will harvest the Mango Sherbert I expect the day time temps to be around 20C. But the 3 sativa I am thinking I will harvest more likely early May or possible mid May when the temps will surely be cooler and below 20C. Yes there is something to be said for cooler climes, it can bring the colours out, and my capsicum plants which have struggled with the heat of summer are now suddenly throwing out lotsof capsicums. My main wish here, is that the weather remains supportive of my grow, we haven't had rain for 20 days, and I don't want loads of it now.
Thanks Tim!
A little while back I actually measured the temperature of the stone tiles of the balcony which absorb and radiate back the sun's heat, the thermometer topped out at 50.5C or 122.9F. Of course now with their canopies covering there is little sun hitting the stone tiles.
For sure, plants can be under stress when various environmental factors have departed from optimum, but cannabis is a very hardy and adaptable plant. Some of those stresses like drought, can cause the plant to increase it's THC and general oil/resin content, just like some culinary herbs like rosemary can do the same. So the stress of a shortage of water can be used to our advantage, stone tiles too! But it is best done during late flowering. Just for shits and giggles, here's somw pics of a couple of balcony plants where dehydration occurred, when they were left without water in the heat of summer for a week, you can see there is a lot of the paving stones exposed and I have no doubt the temperature of the paving would have also reached a similar, 50C/122F in the heat of the days with no water. They look pretty crook there, close to being terminal, but they did recover on being watered, and went on to give me close to 20oz from memory. So they can take a lot, but everything has a kryptonite point, I was lucky that time in avoiding it!
Well that made me laugh. As an outdoor grower, the first 3 pictures show one of those times when I did actually mind! It was my worst fears when I saw them, but they recovered, so thankfully our favourite plant is a hardy plant!
HOLY CRAP!!! What a recovery that was! Wow, I really didn't know they would come back from THAT. Wow. I thought I knew resilient. Damn. Thanks, Stunger. Excellent examples and explanation.

Speaking of terpenes evaporating, 2 years ago we had a hot spell after I'd harvested and the concentrated smell of terpenes that seemed to be spilling out from under the door was intense. If I can manage to bring the sativas safely to harvest at least the temps will be cooler when their time comes.
Thanks Tim!

This is them near harvest time

And your plants are doing a great job of hiding that balcony...
Cheers Carcass! As you know, it's all just trying to avoid stuff ups at this stage.
Thanks Tang! The Mango Sherbert will be ready in 4 weeks, so once I get her off the balcony there will be more room for the 3 sativas. I haven't grown pure sativas before, and so far, the Malawi/Ethiopian & Hon/Pan, both look quite fine to me, and they are in the same soil as the Mulanje, and they appear to be getting their needs met from that soil.
Up potting would have made it even bigger ha ha these things are huge bushes if you dont use some control on them.
