anyone dealing with unusual heat?

How are everyone's plants handling the heat sofar? I saw the heat wave isn't supposed to break until Sunday night. Keeping my fingers that your ladies make it through!

Anyone noticing any strains which handle the heat better than others? Back in my indoor days the only strain I could run in the summer without AC was satori. She loved the heat

This is where growing outdoors (and farming, for that matter) has always been a challenge, but with climate change it's even more so. Normally I'm hunting for strains that are mold and PM resistant, now I'm searching for strains that are heat resistant. What are the odds one strain would be both? This is why I grow so many strains at once, the hope is that some will thrive in whatever that summer turns out to be. It fits (at least partly) with the criteria for ecological resilience: diversity, modularity, redundancy.

@Humanrob maybe more than you think. I've grown Autos outdoor from -2C to 50C +..they are generally hardy beasts.....

Look at the climates where marijuana grows wild- Afghanistan, India, SE Asia, Siberia. Everywhere from desert to steaming jungle. In June several years ago I traveled by car along the Mississippi and Missouri rivers from Louisiana to the Dakotas. I saw a lot of ditch weed growing various places. Some was ten feet tall.

Cannabis is naturally rugged and Hardy for sure. But most of the modern drug strains are so far detached from their native ancestors that they're almost a seperate species at this point.

Survival is the selection pressure and the process of nature. But its been many generations since most of our cultivated varieties have been selected primarily based off hardiness and resilience.

Mossys dragons are very resilient, but her breeding program and selection pressures are alot different than what most modern Autoflower breeders are doing. Alot of this stuff that's been bred and babied indoors really doesnt respond well to extreme environmental stressors in my experience.

Add to that that alot of people grow in above ground containers and greenhouses, which makes an extreme heat event like this even harder on the plants. It's hard to imagine there won't be some casualties

Probably also worth mentioning, that while strains (and landraces) of cannabis can survive all over the world, I doubt any one strain can survive in all of those circumstances, meaning we are still choosing for characteristics that best meet our region. With everything becoming more volatile, finding the right match becomes more of a challenge. Adding to that, akin to @North Forge 's good points, the countless strains being bred currently seem to be looking for potency and frostiness (noble quests), but not necessarily resilience.

But to argue in circles, @armanidog 's underlying point is also valid, that cannabis by nature can be a tough adaptable plant. So far mine have surprised me and survived circumstances that I thought were beyond their capacity.

My two week old seedlings survived 115* over two days. Mix of genetics... In ground appears to be the way to go. I just put some buckets next to them to create shade.

But Oi Im gonna start them inside with the no stress cup next year. I lost so many seeds due to cold ground temp, I wasnt aware of that being a problem. First in ground grow... Oops. Live and learn.

Live and learn is how it goes.

Seasons always varied year to year, but with that becoming more pronounced, I'm thinking next year I might stagger my sprouting more. That way if the beginning or end of the season are not conducive to growing, only some will be effected, but hopefully the whole crop won't go one way or the other.

This is a huge and underrated benefit to autos. With a staggered planting you're less vulnerable to a bad stretch of weather in early veg or late flower. It is a great way to hedge your bets against the weather.

Do some research. Look for breeders who live in your area. Look for seeds that say they can handle hot temps, look into a shade cloth. Look into sativas, and more topical strains. Just need to put in the time and research it.

All my strains are selected for handling low temps, and they did just fine.

I've done plenty of Research on strains, and have a pretty extensive collection. Heat tolerance isn't one of the criteria I select for, it's unnecessary in my location.

The reason for the question was because it's on theme with the thread and can provide useful info for people who are researching heat tolerance now or in the future

Anyone have any plants which really couldn't handle the heat?
