Beautiful work @LKABudMan, frosty as!
Droughting and its medicinal effects in cannabis
- Thread starter Krissi Carbone
- Start date
Hi there fellow droughters! Today is the 19th day that I have been employing cycles of wilting and rescue drinks on my Mango Sherbert. She's looking pretty beaten up but I am not growing her for her leaves! I will look at harvesting her close to 2 weeks time I'm guessing. So far further fine and dry weather is forecast ahead. I put an update here just to show how she is getting on.
This is a pic of her yesterday morning, looking quite wilted and hanging out for a drink - that was her 18th day since stopped watering her, and keeping her in that state by giving her 'rescue' amounts of water only.
And here she is this morning on her 19th day after yesterday's 2L (half gallon) rescue drink
She first displayed a similar look to yesterday's on her 7th day of no water, and since then, I have just been giving her enough water to keep her going, and then letting her wilt again.
Here are some close up pics of her trichomes as she is at this point in her drought.
Cheers.

To you as well @Stunger that mango sherbert is coated!

Well, I made it to page 21. Anyone know which page contains the droughting technique? Or is the technique to stop all watering for 9-11 days, based on leaf angle, around d week 7/8 of flowering?
I may be opening a can of worms with this post, but, this is speculation on my part. Please only take it as such.
Growing in the Kratky method teaches you a lot about roots, and how a plant can alter its root system to suit its environment. As the plant consumes the nutrients, root mass gets converted to air roots (probably the wrong terminology) to let the plant breathe.
When you retop a Kratky system, you have to be careful not to drown the plant by submerging those air roots.
Now....how long does such a conversion take place, or if that would even be a factor in a prolonged drought is beyond me. But I thought it would be something to mention and discuss.
Might be nothing at all, or it might be an important factor....I dunno.
I'm obviously very open to having a conversation on these speculations.

Hi Rexer,
The opening of a can of worms is how a lot gets done.

Hi Tim. Is it indoor or out? Also what is your flowering period?

Indoor soil and breder says 9 weeks flower....but that never seems to hold for me ha

Then I would think you are on the money for right now. Good luck and may the buds be frosty! 
Here's a couple of bud shots I took of my Mango Sherbert today. It is her 20th day that I have been denying her water and letting her wilt, then rescuing her with a small drink to let her wilt again and so on. Just for the record!

I have a serious craving for some Mango Sherbert ice cream. Not sure if there is such a flavor, but I want some.
Fabulous flowers.

Is the GRN triggered by all, or most, stress situations in addition to droughting?
If so, does it always react the same, resulting in increased oil and trichome production?

Yes, the GRN will react to all abiotic stressors, but not equally. The application of drought has a special direct correlation with ABA wherein most times the phytohormones must act in concert. For example, with an insect infestation the GRN will need reset the homeostasis for ABA and a blend of hormones to trigger the essential oil production, but in a drought the low moisture reported from the root zone sensory cells is directly translated into increased ABA synthesis in the roots by the GRN.
I do think there are many ways to accomplish applications of stress, but the drought/ABA relationship is hard to overlook. I use alternatives like MeJA and GA, but that is not for this thread.
Is there a minimum amount of "low moisture" time needed to trigger increased ABA synthesis? Is increased oil production immediate, does it accelerate over the duration of "low moisture" conditions? Is there a limit to the number of times it can be triggered?
I know, a lot of questions. I'm about a week or two from attempting this in hydro.

I will help if I can but @Rexer is my reference for bubbler droughts. I am in peat & perlite.
I am not sure how long before the low moisture equates to increased ABA.
As the folks in labs coats will tell you "This has yet to be elucidated".
That means "we don't know" in scientific jargon.
this is a good question, and to relate to a soil drought, it would equate to where some residual moisture is in the soil. But anything beyond that is not something ive looked into.
It was/has been postured that duration of the drought impacts the plant's producing resin (with an increase), vs a quicker one. The conversion would be further back in this thread.
I think @Maritimer might be best to answer this question. I've never done more than the once. I'll be doing another this summer.
All good brother. With a water medium, i dont know if its been done yet.
I think for myself, and my style of growing, targeting the LWA will continue to be my preferred method, vs targeting a longer drought.I will help if I can but @Rexer is my reference for bubbler droughts. I am in peat & perlite.

The LWA just seems to have a more measurable way of determining the state of the plant.

Doctor Caplan using statistical data from adequate specimens has proven that repeated droughts has adverse effects. During the same set of studies he determined that using LWA and applying drought, when a delta of 50% indicated wilt has been attained the cultivar has been stressed enough to have engaged enhanced oil production.
Rexer has even found an app that helps better see the target wilt. Best way to go until you get the feel for droughting. Truth be told I have not used my angle finder in a long time.
But for new droughters, LWA is the way.
@Maritimer , @Rexer ,
Thanks for the responses. Having spent some decades in one of those lab coats, and bunny suits (semiconductors), I'm familiar with the " as yet to be quantified" or other I don't know responses. That is what drives science.
So to recap, my best plan would be to remove all solution from the "DWC" reservoir and observe the LWA until the poor thing can take no more (I've read the entire thread and am familiar with the proposed 50% change in LWA and how to measure it). Put the solution back in and let her recover before harvesting.
It sounds as though repeating these steps could be counterproductive?
Do you think it might be possible to provide enough solution to the roots to maintain the 50% delta, once it is achieved, and keep it from wilting further for an extended period of time? Perhaps a 10% res level?
I've already harvested the top of this plant so I am open to experimentation without reservations.

Ahoy @Hafta,
I must first discuss the matter with @StoneOtter but it my impression you will make a fine science officer, and a welcome member of the crew. "To bravely go where no hobbit has gone". We will give you the immeasurable support a cannabis pioneer deserves. Plus, the pay is tops in the private sector. kidding
Sir, unless I got it wrong from Rex, it is you who will be answering your own questions as you head into unknown waters. We will be your studious comrades.
Press on @ your leisure Commodore.
