Debunking the recommended temperature range: Don't plants withstand high summer temp?

[theblues88]

It is recommended that the temperature of the grow room should not exceed 85F, but if we consider the temperatures they support in summer heat, which can easily exceed 110F, what is the validity of this recommendation?

[UrbZ]

There is abundant co2 in nature. Grow rooms with co2 systems can grow plants at much higher temps because of the co2. Most normal grows people dont add extra co2, so the plant stops growing because of high temps in the normal grow room without co2 implementation.

1 full day in a tent at those temps could kill a plant. One day fine the next completely on the soil.

Co2 can increase the maximum temperature but indoor grows sustain the same ambient co2 levels as outdoors. Only if there is insufficient airflow would levels drop below outside ambient.

[GreenDragonRon]

They might survive but they don't thrive and won't produce a large yield. I've never had an issue with high heat but if I did, I would certainly try and keep it within the recommended range.

The idea is plenty of air movement around the plants top and bottom not counting tune abundance of co2 outside u can't recreate these conditions inside because there are too many problems that would arise.

[Jr83]

Y would u try to debunk a fact of indoor growing i say do a side by side comparison if u need to that'll prove top i whatever it is urc trying to do

Currently the temperature inside my tent is 92F

[UrbZ]

Do you have fans/ventilation.. are your side flaps open?

also could add this or some similar product.

Have a 160cfm exhaust. Two passive intake vents are fully opened. Today was a very hot day here. Temps were around 90F

Plants survive a multitude of things that prevent them from doing their genetic best.

If you can't get the temperature where they need to be ,you can't expect much of a harvest. Especially when flowering.

Last summer my tent would get to 90 95 and for a few hrs in the middle of lights on with the low temps in the 80s I still flowered and got a real good yield but I had lots of root problems i grow in dwc. I move lots of air inside the tent also.

[DrPhoton]

I grew in constant 90°F and often got to 95°F. However this was in veg which is more acceptable. I wouldnt want those temps during flower though. I came out with 2 pound plants. Outdoor greenhouse of course.

[DrPhoton]

Temperature is directly related to the efficiency and functionality of enzymes and photosynthesis. As temperatures drops below the ideal, enzymes which carry out important tasks for photosynthesis, begins to slow down. As a result, photosynthesis also slows down. When temperatures rise above the ideal, enzymes become deformed and dysfunctional and presents the same problem as low temperature.

Plants take a very long time to mature outside. One reason for this is that nature does not supply ideal conditions. I've read this thread and its full of confirmation biases. Sometimes it snows in July, that doesn't mean you should subject your indoor cannabis to adverse conditions. At night your plants will benefit from temps from 60 to 69 at night more like 70 to 79. This is wisdom. Don't let charlatan's cloud your mind. We grow weed easy around here. Break legs!

In July?

[LaughingBuddha]

There is abundant co2 in nature

No, just no.

[UrbZ]

Co2 is the is fifth on the list of gases that make up air you're a tool now you're just trolling.. You need to actually read some scientific stuff in your regiment because when you speak you just sound stupid.

Co2 is more abundant indoors than out but that doesn't matter. Only if all other conditions are optimized is co2 viable. Adding co2 to compensate for inadequate cooling is anecdotal at best.

Now just a minute,I’ve grown mex. weed that could withstand higher temps because of genetics.
and I’ve grown indoor weed that could never do what the mex. can outside in the heat ! I beleave genetics
play the biggest role. Lol

[RosettaStoned]

I would say that being in soil outside has a little to do with it too. There's an incredible amount of soil the plant is in. It would take an extreme amount of heat to raise the soil temp, maybe the first couple inches. Also the average temp for the ground is 55 to 60 degrees, so that helps as well

I'm actually somewhat skeptical of the claim that cannabis thrives in areas that routinely reach 110 in the summer. Even in desert areas like Afghanistan and the Riff Valley of Morocco, cannabis is primarily found in mountain environments. One of the reasons I've moved to autoflowering plants is because in the state where I live and guerrilla grow, I have a tough time keeping them alive and thriving during the sweltering hot summer even with plenty of water. Being able to harvest in early July means that my girls don't spend 3 months burning up in the Tejas summer sun.

[LaughingBuddha]

You should be skeptical because it doesn't thrive as a flowing female in this contitions. If it did though. Indoor growing should b be about optimizing conditions not anecdotal solutions to simple problems. Remember folks it's supposed to be easy.
