Cannabis Science " Community Thread"

[SouthFloridaGenetics]

Greetings,

Thank you for being part of my life, I appreciate everyone. This thread is a place to share science about cannabis. There have been many milestones reached due to our relationship with cannabis. In my life I have had many friends, many jobs, many relationships, many hobbies, and many activities and I can say with confidence that the inclusion of cannabis in my life has made life wholesome and complete for me. I am a nerd also, went to college and got a degree in mathematics, physics, chemistry, and biology. It kinds resulted in me being a scientist. At any rate, I have an interesting background and have loved living my life. I am a real Kush Master also. With my experience and education I wanted to have a place we could all meet to share the science behind some of the things with cannabis.

My first contribution is a study conducted by some scientists on cannabis sex reversal. Enjoy the material and let us know if you have any experience with this.

I love you people!

Things I would like to see in cannabis technology.
Open source grow room tech for condition modification and tracking
Growsensor looks great but lets push it. HD cameras to detect leaf curl and color changes. Make the led par maps integrate with the sensor making adjustments to energy levels. Basically every leaf is in the top of the canopy.
3 zone atmosphere control. Pots and buckets in one setting veg in another and canopy another.
More and more intrusive warning sensors when things are out of range. Currently the app I am using puts a tiny red light on the opening page. I want it to sound a train horn.

This white paper discusses "Total production achieved with F1 hybrid seeds can add up to 1.23 lb/ft2 per year."

There is a lot of focus on feminized seeds! The pressure is on. And everything gets better! The yield, the quality, and the THC% all improve with feminized plants. This is definitely going to get the market even hotter! We are alive during this time! Man that's great.

Here is the abstract:

Cannabis sativa is a widely studied species and is currently accepted worldwide due to its medicinal properties, especially those conferred to the CBD phytocannabinoid, which is synthesized mainly in the globular trichomes of female flowers. Males are undesirable and rare in commercial plantations;
however, they are necessary for breeding programs. This research aimed to evaluate sexual reversion methods in female cannabis plants as a preliminary stage of a plant breeding program. A completely randomized design with eight treatments and four repetitions was used. The treatments
consisted of protocols for the sexual reversion of female plants through drip application and foliar spraying of Silver Thiosulfate (STS), Aminoethoxy-vinyl-glycine (AVG), 1-Methylcyclopropene (1-MCP), and Gibberellic acid (AG3), plus a control treatment without application. Male flower production was evaluated in female cannabis plants, and pollen viability in male flowers was determined. The AVG treatments applied to the apex by dripping, and the AG3 applied to the foliage in the form of a spray influenced the sexual reversion of female plants and produced a total of 132 and 32 male flowers, respectively, without difference between them (P=0.08383). For AVG dripping, only male flowers were observed at the apex, where the application was made directly. Moreover, STS and 1-MCP did not induce the production of male flowers. The pollen from male
plants treated with AG3 in spray, and AVG dripping showed high viability (>50%), contrary to the low viability observed in plants treated with AGC applied in spray. The plants treated with AG3 (spray) were higher due to the elongation of the internodes. The AVG and AG3 compounds are effective in the sexual reversion of female cannabis and generate male flowers with viable pollen.
