Is this plant heat sensitive? Hightest temps it can take without making problems.

[the gnome]

Ive run 2 GS hybrids in the last 2 months and temps ahve hit mid 80s with no probs, currently have 4 gs x gsbx2 @39 days and no probs with those at mid 80s

I'd say that your fine up to 85 for sure.... Also, a plants threshold for heat is directly related to co2 levels and moreover photosynthesis rates.. As long as your rh is steady a plant can do ok in higher than average temps provided hightend co2 levels...

This has always been my understanding of it at least, anyone else know of this?
Remember to keep your temp gauge at the canopy, as it's usually away hotter than the stem. Good luck with them! You'll love

I forgot to add,
I'm not saying mid 80s is ok temps for the plants but they will tolerate it but
your plants probably will give you a a less than optimal fruits than if they were
grown in more ideal temps like the mid 70s

Hey gnome, I have always wondered bout the optimal temp ranges for trichome heads. My understanding is high temps(mid 80s) is usually justified by growers by the increased yield(slight).
Would you say this is at the expense of tric concentration/density?

I've also wondered what role heat plays in the taco effect seen in sugary leaves... Seems as though they remain at the top, perhaps too hot.
Any imput is greatly appreciated, as the path to mmj enlightenment is never ending, and I have much to learn

take into account Ive only been growing indoors for 2 years.
and from what ive have read my understanding is higher temps in flowering can cause the flowers to be less dense and cooler mid 70s would aid in denser budz, I think trich/resin factors are largely geneticly influenced...
thats the quick answer

the longer reply if you care to read on is this:
Ive thought about this since the 70s
as far as 10 degree temp differences contributing to trich concentration/density
I think its a catch 22 type of situation.
if you look at indicas/kush's that grow at hi altitudes that are subjected to much more intense UV exposure were seeing some of the best hash plants in the world and hashplants have lots of trichs so I'm thinking a higher UV exposure is directly related to trich density to deal with the UV.
but then I also have to take into account the fine hash that also comes from the low laying places like the bekka valley in lebanon or from india and an they also produce an outstanding hash product also with much lower UV exposure....
and to complicate that theory even more you toss in the extremely potent equatorial sativa's
thats the catch 22 imo
seems for every notion no matter how well thought out and makes perfect sense thing we come up with, another well thought out perfect sense notion seems to cancel out the other??
A catch 22.

after thinking about this for some time I think strain/pheno's genetics have the biggest influence in how that plant will perform.

I'm still very new, 2 years to indoor growing and its different from the outdoor scene which I did for 8+yrs.

and even in the outdoor scene we/I grappled with the same issues with how to get the plant to produce more trichs/resin.
back in the 70s it was thought the drier climate would induce the plant to produce more trichs and resin to protect it from the low humidity, but then again looking at the fine humid lowland columbian punta roja *redbud* did the same thing to the dry humidity more resin theory as the hi uv hi altitude more resin theory thats countered by equally good lowland grown hash plants

catch 22 again and again.

my take on it now is its down to the genetics, all the types of landrace plants adapted to thier particular enviroment over thousands of years and made the most of it as do animals and people.

what we have now is so many different hybrids derived from differing landrace strains thats still have in thier genetic make up the conditions that the plants adapted to generations ago.
and it looks like now were at the point with these hybrids that we can manipulate the qualities to our benefit just as the enviroment shaped the hybrids ancestors way down the line.
monsanto and other big agricultural companies have been doing this for many years and now have drought resistant, fast maturing, heavy fruited, disease resistant corn and other food crops.
and with the coming of legal pot in less than 10 years you better believe this big agri giants are already working on geneticly breeding/modifying the perfect canabis plant, one for this and one for that.

have I baffled you with bullshit yet mr smith? LOL
bottom line I still think it comes down the genetics of the strain/pheno preferences thats have the overall biggest factor in whats going to determine tric concentration/density

as for your other Q
**I've also wondered what role heat plays in the taco effect seen in sugary leaves... Seems as though they remain at the top, perhaps too hot. **

I haven't done enough indoor growing to give/formulate a solid answer, but going back to my outdoor grows I never experienced the taco leaf thing no matter how hot it got,
the leaves just drooped in the heat of the day90+degrees or mor at times
so us as growers trying to simulate the outdoor enviroment indoors seems to play a role.
I think heat is a factor combined with, again ...genetics.
Ive seen leaves taco'ing on one strain/pheno when it was pretty warm and not others,
plant age may also be a factor combined with heat or Ph/nutrients etc etc.

ok so i thought i posted a reply to this a few days ago but apparently not....hmmm

gnome i really appreciate your input here....
i really liked what you said .....especially taking the fact that all strains were developed, or adapted so to speak on a particular continent with a specific set of conditions....
these are the traits we see that define specific parameters of preference like temps, feed, and lighting.... i think too often we forget that only in the last 100 years have we plucked most of these landraces from thier homes and brought indoors. '
for instance i let all my bubba xs get bone dry before watering.... because they hate wet feet...... hindu kush region of afghanistan gets hot! ....little rain.... little food....
no wonder they hate nutes in veg, and react badly to overwatering....

Also, i have done some more thinking/research on the taco thing.... i kno that there are other strains ive seen that taco in mid 70s all the way down the plant. one that ill mention is the tiny bomb from tga subcool seeds..... this strain is extemely resinous and its leaves are almost not visible from the top due to the massive taco effect
if anyone wants to see some beautiful concentrates.....check out subcools beachsand bubble from his tiny bomb cut....really nice

my initial response was a bit more thought out.... my comp is down any im on a kinda jerry rigged system so im gonna post this before i lose it again

Exactly danksmith!

I think you wrote in one sentence what took me 20minutes to say
