Hi
I am looking for these varieties place of origin and more specifically what there optimum and maximum growing Temperature tolerances are.
(Round about)
It would be good if I could get some feedback from the breeders but also your experience maybe helpful to me.
For example our loca Sativa grows fine in constant periods of 40 Degree C, even tolerates 45 Degrees C.
This can not be said for many commercially breed varieties even from my limited experience.
So I guess you could give different plants a rough rating system of 0 to 10.
0 being good tolerance at 30 Degrees C
10 being good tolerance at 40 Degrees C
On this scale our sativa would be a 10.
?Sound Interesting.
Hope to get a few Breeders interested and some feedback for my specific varieties.
C99 and Sensi Star.
Cheers (back when I can, please feel free to start without me )
Some generalized information and thoughts on temperature to contribute to the post.
Experimentally some South African plants were found to have the highest level of THC when grown at constant 75 F / 24 C.
There are many factors including temperature that can determine THC and yields in the uncontrolled natural environment.
Lifting soil temperature a few degrees C above air temperature can increase growth rates for moderate temperature ranges.
Peak rate of growth for some cooler region plants is about 80F or 26.6C Ambient, other strains near the equator peak at about 90F or 32.2C yet there are a lot of much hotter environments growing healthy cannabis.
The Plants ability to acclimatize, with no doubt extends the upper range of temperatures for some varieties and individuals.
There may be no growth once a plant species reaches its maximum tolerance.
A Plants temperature tolerance before going into survival mode depend on variety but could be in the region of about 105 F or 40 C , some varieties may continue growing even at above these temperatures.
Plant yield can suffer at these temperatures.
Potency can be high for some varieties grown in a hot environment which brings in the question of how other outside environmental aspects affect the plant.
There is one distinct difference between the inside and outside?
That of light: differences in spectrum, intensity and in the type and level of UV.
High light intensity and temperature may alter the plants upper limits, were lowering the light intensity can reduce the plants metabolism and temperature tolerance.
High natural UV could also play a role; UV in nature would likely not result in a 24 hour damage and heal cycle for the plant but a built tolerance along with some chemistry changes.
A good soil temperature to germinating warm climate cannabis seeds could be 80°F or higher, this is equal to 26.6 or higher in Celsius.
Knowledge in plant tolerances can be invaluable for determining the best planting time and maturity for the environment or to alter the environment to better suit the plant.
I look forward to learning specifically about the flagship varieties such as C99 and Sensi Star.
