Pure Thai Sativas

[justabluez]

I just bought a pack of SnowHigh Dragon Fire (Lemon Thai X Burmese X Angola Red X Meao Thai X Purple Thai). Does anyone have any info on how long they think this cross would take to finish flowering? Maybe 12-16 weeks?

 

[Mustafunk]

Why does the strength and quality of the high from many tropical sativas improve dramatically after several months correct storage compared to smoking the same plant just a week or two after harvest? And of course all strains show improvement, from my experience most indica or wide leaved drug cultivators seem to be only slightly better after 3 months compared to trying it after just 2 or 3 weeks while long flowering thin leaved tropical landraces definitely get several times better.

Strength raises because of the cannabinoid decarboxylation occurred when curing them. THCA converts into active THC and so on. In the same way, many terpenes get lost in the process and others remain, thus the change in smell and flavor. Generally monoterpenes are more volatile and dissapear soon while the woody/spicy sesquiterpenes remain more intact.

The reason why tropicals seem to improve more than hashplants with a long curing I can't really figure out why, as the processes should be the same in both, isn't it?

The reason might be that the tropical narrow leaf, long flowering strains's trichomes are different from wide leaf short flowering strains?..perhaps the release or change in the terpenes is due to a thicker trichome outer membrane? Maybe sativas were selected (by the environment and human selection) and these selections (for eg potency) had a thicker or stronger trichome membrane to survive the 2 or 3 extra months of sun, wind and rain and this is why they require months of curing and storage to attain their peak high?

or is it simply that the terpenes in tropical strains are different from 55 day cultivators and they release/change at a slower rate?

 

[biologic]

I never cure.

 

[misterD]

Sativa are like good red wine,.. like my mom said, they need time to enhanced the better out of her!

If i can score a nice oaxacan, i'm gonna be able to trade back my "Red Thai"

 

[waveguide]

haven't met a strain that wasn't profoundly improved by ..say 2 months. save some biologic.

Hey Musta

Wouldn't putting a flame to THCA cause it to lose its carboxyl group immediately?

Abstract
Sequence variants of THCA- and CBDA-synthases were isolated from different Cannabis sativa L. strains expressing various wild-type and mutant chemical phenotypes (chemotypes). Expressed and complete sequences were obtained from mature inflorescences. Each strain was shown to have a different specificity and/or ability to convert the precursor CBGA into CBDA and/or THCA type products. The comparison of the expressed sequences led to the identification of different mutations, all of them due to SNPs. These SNPs were found to relate to the cannabinoid composition of the inflorescence at maturity and are therefore proposed to have a functional significance. The amount of variation was found to be higher within the CBDAS sequence family than in the THCAS family, suggesting a more recent evolution of THCA-forming enzymes from the CBDAS group. We therefore consider CBDAS as the ancestral type of these synthases.
-----------

One thought I have is that in NLD types, the remaining CBGA and CBDAS in the resin may be converted to THCA throughout the course of the curing process. This may be part of why the plant stops curing when dried too far--enzymatic process halts. I also agree part of it is monoterpene degradation, as you do.

One more thought with less foundation to it (probably wrong but an interesting thought, I bet Sam already knows)--what if during curing, delta9-THC is converted to 11-Hydroxy-THC in NLD types? This already happens naturally in our livers when we consume edibles, leading to what most agree is a very strong high. Or perhaps some NLD types are already naturally high in 11-Hydroxy, don't know but would like to find out...

Nice one numide, content de voir que tout roule!

I just wonder, did you managed to save a clone of your mango thai? I find the way too save one of my "red thai" in my case!

Samson,
I got 4 Thai sticks in the late 70's that had 2 seed. Very trippy. I grew both and I know what you mean by never finish. They went 10 months, then hermed.

Tropical sativas need more than 12/12 darkness. More like 11/13 or even 10/14. It seems to load them up with more flowering hormone.

Thailand is not exactly on the equator, where daylight is exactly 12/12. It is between 6 and 18 degrees of northern latitude. According to Climatetemps, in Bangkok:

The longest day of the year is 12:49 long and the shortest day is 11:10 long.
The longest day is 1:38 longer than the shortest day.
At midday the sun is on average 72.6° above the horizon at Bangkok/ Don Muang.

There are some plants in this line with the most beautiful thin leaf profile. Others more mid wide leaf.

For your viewing pleasure....Chiang Mai Tai.

i have done all my tropicals 11/13, since i did some 12/12 and preflower did last around 2 months. also found that under 11/13 they don´t veg proper(under leds), so more veg before switching to 11/13. 10/14 could be good when plants are finishing?

Beautiful Beautiful Beautiful. I have a few seeds of this line. When I get around to it I hope they look as nice.

Hola Sampson4, she has greatness in her bloodline. I've worked different Thais, and the ones you have show more the classic thin leaf profile.

I didn't want to keep all my Thai confined to my journal. Why not share it with all you Thai lovers here too!

 

[Huesos]

I love how those poddies form late in maturation

 

[Lester Beans]

167 days, wow. Going to need a smoke report on that long in the tooth gal!

Dave,

how much did it stretch?
