Are these dying or getting ready for harvest?

[Olive Drab Green]

lol not gonna even waste my time. you obviously dont have experience on what real heat stress looks like so I just hope OP takes the advice given to him with a grain of salt.

SO much misinformation on these forums.

Alright. Show me statistics if I'm wrong.

 

[Olive Drab Green]

I can understand disinformation and misinformation pissing you off. So educate me.

Most strains can't handle that. Guaranteed. Maybe in your case, it worked out. I'd bet more often than not, your results would not be replicated.

What is the difference between a California grow outdoors in 90F plus heat and my closet with good air flow and the same temp?

You seem like a pretty knowledgeable grower but heat isn't as huge as a factor as everyone makes it out to be. Check @RM3 he's admitted to his temperatures, specifically canopy temperatures, to be 90F almost the whole grow and his buds are frosty and fantastic. I hate I have to keep referencing one user but he pretty much provides substantial evidence that these plants aren't as weak or complicated as we make them out to be.

Edit: Going to add on to this. While 75F might be the optimal temperature to grow at no plant or grow is ever going to experience optimal conditions 100% throughout unless it's a really well thought out and dialed in grow. You can find many users who still manage to produce fantastic herb while dealing with heat, nutrient, and other stress factors that many would think would just ruin a plant.

Edit 2: Don't forget why we call it weed, lol.

No need for statistics the proof is in the pudding. Look at the OPs original post and you will clearly see a MJ plant that is suffering from a nutrient lockout, probably from PH or to much of something, ive never used AN and for good reason. Heat stress doesnt cause the plant to eat away at itself like that.

My first thought was root rot if heat had anything to do with it, but I see no pythium in OPs roots.

 

[Olive Drab Green]

I'll see what RM3 has to say about it.

 

[Olive Drab Green]

I was under the impression an open air outdoor grow and the heat confined to a small grow space made a huge difference. I'll clearly have to do more research on that part.

 

[Olive Drab Green]

I believe you guys, though. If there's evidence of it, I'm down to investigate what I may not know.

It's air flow I think. Even though the temps are the same both grows are constantly getting airflow. I have a 400CFM fan bringing in fresh air to my tent and the negative pressure turns my passive intake into a mini wind tunnel. Although my temperatures read 90-95F according to my thermometer the air itself feels nothing like it. Feels like a balmy breezy summer day inside my tent imo and that would replicate the outdoors of my area actually, living in a tropical climate and all.

While I'm not entirely positive what the cause and effect is I do know even though I have hit 100f on my tent I've never had taco leaves and I believe it's simply the fresh air flow. Sounds like we both have a little something to investigate. I mean I know whatever I am doing is working...I just don't know WHY it works. lol. Story of my fucking life...

Truth be told, I dunno. I have a few heady bagseeds from a dealer bag. Maybe I'll experiment.

Hello friends, I really appreciate all of your input. I think the heat thing goes strain by strain. I can tell you that my indica dominant plant i had growing next to the pineapple sativa dominant girl did much better and didn't seem to have a problem with the heat. I believe that my issues began when my ph meter broke. So yes, I believe it was a nute lockout couple with just warm ass water that made them wilt. They've been doing better. The temperture gauge in my room broke lol but its alot cooler. Unfortunately it seems the universe wants me to finish early so i will be harvesting pineapple girl asap since the place i had em growing is no longer viable. I was wondering how bad would it be if i harvested my pyramid auto purple? shes not even turning purple? oh well, i have to move them again so we will see.


As for saving the pineapple, she is doing much better her leaves started drooping less when i flushed and got more airflow in the room. stale air deff bad.

if i harvested purp girl would she even smoke?

 

[heliophant]

Trich shots :3?

So I'm seeing two different color of pails, the healthy roots were in white pails. Are the roots in the black pails the same white healthy ones as the white pails? I would have said you have root rot given the look of the plant from top to bottom. Still say it's rot but the white pail roots look fine, you got any pics of the roots in the black pails?

This is true stuff. Think of it like a HEAT INDEX or a "Feels like"
Most people will just hop on here and try to blast people for giving "Wrong" advice and in reality you wouldn't be on this forum if you were seeking one individuals advice. Some people ::Cough:: just think they are always right and have small little pea brains Truth be told resin production is at its peak during the fall temperatures and this is a scientific fact. That means that 100+ temps are not optimal for budding. Could this be causing your plants to die, Maybe. I think it more pertains to you getting close to the end of flower and your plant was lacking in some nutrient departments. Make sure your res is always PH'd and you are feeding properly. Best of luck!

Are you talking to me? I don't use a res, not a hydro grower nor am I OP of this thread. None of my plants have died but it's obvious that OP's plants did not die from heat.

Also just pointing out that while definitely 100+ isn't optimal for budding in nature and outdoor grows the plants are exposed to day time temperatures reaching upwards to that limit and possibly higher. Think about it, California growers have to deal with high temps outdoor year round but you never hear anything about how their outdoor grows aren't budding optimally. Heat can be stress on your plant but I'm beginning to thinks it can also be your friend as long as you have the proper mitigating factors in place i.e. airflow.

Just to clarify I'm not advocating for high temperatures when growing indoors just trying to get across to the new growers like myself that it seems getting the heat in your tent down is nice it's not entirely necessary so long as the conditions surrounding your plant are good. I try to keep my tent well circulated and I believe my plants are happier for it despite the high temperatures.

Case in point below my last grow I did. I'm still rather new and these plants suffered a little more than they had to due to me fucking with the nutrients too much as well keeping them in what I now think was too small of a container. But my temperatures did not stop any of these girls from becoming quite large or budding up. I pulled between 4-5 O's between these three plants that I considered well well well fucked up but my temperatures were 95F at the canopy on average. But they still grew and budded wonderfully!

I always thought resin production was tied to UV but yup resin does sure seem to increase at the end of life as opposed to the beginning, food for thought . My plants are in 100 f right now and the only side effect is I work my ass off watering them. And the auto's are in peak production .

Metabolic energy is usually governed by environment values, we all know that different cannabis species can thrive in different environments however, it's a highly adaptable plant in veg so you can usually get away with alot of shit untill you hit a runt/sensitive pheno.

Outdoor plants can handle higher temps BECAUSE THE ROOT ZONE IS KEPT COOLER from lower ambient temps and shaded pots or grounded roots coupled with constant fresh air from all directions and it will be much much more forgiving on a plant with high foliage temps.
