Highya Krissi,
Love the lights on drought pics! So, do you drought them, then harvest? I've seen StoneOtter do this, but didn't seem as much trichome increase as you have. I'm impressed. It seems that growing cannabis is a super-talent. your skills are getting more interesting! Happy Smokin'
Thank you!! I've got much to learn!
Well Bode, I couldn't drought them after harvest
Just kidding! I know what you mean, at least I think I do!
You should be droughting at week 7. A longer flowering strain you could do week 8. Honestly the study was a great study but the only one, so all of the droughting we are doing is based off of that 1 study, what we have heard from others and know about droughting in vegetable crops along with a lot of trial and error, seeing what works, what works best and what doesn't work.
It's different for all mediums as the study was done in soil. So I can tell you it is a controlled drought for up to 11 days. We pick the weeks we do to drought because that is when the GRN (genetic regulatory network) in the plants starts telling them to crank up and finish off. But in their head, they just think there are seeds in the flower that are getting ready so they do everything they can to protect them.
OK so basically...
In a drought, when we drought, the GRN sends these "O fuck" signals out to all the protein receptors in the plant.
Different proteins are responsible for different things. ABA, absicic acid, is the main component or driving factor in a drought. It is this protein that tells the plant to increase resin and trichome production. During this time, all those other proteins that are responsible for things like THC CBD also amp up.
The only thing the plant cares about it saving the seeds they think are in the flower. So that GRN system tells the plant to take care of the flower and screw the leaves. That is why you would use a LWA (leaf wilt angle) to measure the extent of the drought. The leaves are what will tell us primarily, when the plant has had enough.
Now, with all that science said, I have droughted a bunch now-every plant since Ammy basically back in October. I have found that not all plants show the distress in the leaves, some show it in the flower. I have found that what works best for droughters is to get fed and spend a few days back under the light for maximum effectiveness rather than just drought to harvest directly. Idk they like turn back on into overdrive just taking in everything like they are afraid to lose it again and they go ham in those final few days.
