Droughting and its medicinal effects in cannabis

[Maritimer]

the way i read it tells me the technique , for plants in soil at least, is very simple

first one needs to know their plants a bit,, knowing when 11 , or 12 perhaps, days from harvest, one stops watering

that's it,, under optimum conditions,, done

one watering after 11 days, or adjusted for ones own conditions, and a harvest the next day


that is straight from the study

of course, ones conditions, situation, expertise, experience, attention to details, fortune, and karma will need to be factored into everything,,

simple indeed

btw,, the study is not a big read and actually quite easy to understand,, sorta

Increasing Inflorescence Dry Weight and Cannabinoid Content in Medical Cannabis Using Controlled Drought Stress

Controlled application of drought can increase secondary metabolite concentrations in some essential oil-producing crops. To evaluate the effects of drought on cannabis (Cannabis sativa L.) inflorescence dry weight and cannabinoid content, drought stress was applied to container-grown cannabis...

btw again,, how to properly organize these threads for ease of use and study has been an ongoing issue for 420mag for years,, still not fixed, or else not used properly,, there is things in place for this but not used much,, so is forgotten

Ahoy there @Maritimer !

I had a private message concerning a specific environmental issue regarding drought. He/She wanted to remain unknown so I trimmed around some words..

I said that I was unfamiliar with this type of condition and would ask for your opinion. My guess was a simple 3/4 days but I didn't want to give the incorrect response

 

[Krissi Carbone]

Understood.

But, eventually, maybe soon, this idea will become common practice among some growers, kind of like bud washing has become. Not for everyone, but for many.

Maybe one of the other practitioners can start a new how-to thread and you can keep yours to more of the science and theory of it all.

Kind of like the 'quadlining' thread, or the threads on making concentrated oils or others like them. They start with a how-to for those that already know they want to do it but are looking for the details from those that have already worked it out. The threads then go on to explore the use of the technique with questions and answers from the growing list of those growers using it and the community fleshes it out over time.

I get that you want to do it like you have. It's your thread. But I think having the actual steps to accomplish this buried deep in the thread won't prove as useful down the line as having it upfront and easily accessible for those looking to dive in and don't have the time to wade through all of the preamble to get to the info they need. Kind of like the grower that was 8 weeks in and needed an answer quickly.

I'm not trying to tell you how to run your thread. I'm just throwing out what would be more useful to me and future growers like me down the road. And having the info upfront and the science behind it could make this thread the go-to standard for the technique. To put it in newspaper language, it kind of feels like you're "burying the lead."

I would say, unlike some, I'm more just casually interested in the science, but strongly interested in the technique, given the success @StoneOtter @Maritimer @Rexer and others have experienced. I'll still follow along for the science, but I guess I'm looking more for a concise write-up as a jumping off point.

Kind of like my car. I'm kinda interested in how it works, but to start, I just want to know how to turn on the ignition and where the gas and brake pedals are. Then, over time, I can educate myself on the why and how's. But I really don't need any of that to get started and enjoy the benefits of the transportation.

WooooW what you started @Krissi1982
Just caught up , im firm believer of each to there own.
And NEVER discount information that could benefit you.
That being said still never got my questions answered.
Also think to stop the sceptics like myself.
As already said here or on another thread.
A Start to finish soil/coco/hemp/dwc detailed would be nice.
As already said i would think EVEN if it works the time scales would be different.
And im still lurking

Happy New Year from the skunksta one and all..............

Hey Skunk...I will certainly take your advice and my next droughted lady I will doc start to finish....happy lurking this new year buddy

For some, I imagine it is very straight forward a concept to understand. There will always be variables unfortunately. Not everything is black and white...room for some level of discretion in all things growing

Well that makes me sad. Reminds me a lot of this generation and how we operate. Need to have things now and no one really wants to do the work leading up to it or have the patience to wait and take things in. Seems as if some people just want to ride the car as you said, knowing that there's a bunch of crap under the hood that makes it work...I sit in my cat and wonder how and why. I guess I'm a dreamer. Guess I just like the hunt more than the kill. It's the getting there in life that makes when you get where you're going worthwhile...imo....

Ahoy @Skunksta
Another very cool screen name. How in the world I got stuck with the name Maritimer is beyond me.

Very appreciative of your announced skepticisms.
I felt the same way as you, until it came together in my head.
This is why Krissi is trying to get everyone up to speed together.

I feel like I'm looking out for the better of thr community this way

Around the world we have testimony from gardeners that have confirmed our protocol.
That should appease your suspicion of failures.
but aye, to each their own

Oh Skunk...he's a curious kitten lol

the young doctor Kaplan has (like many of us) gained a great deal of experience since the original study was published. if he were to write his thesis over (hehe) a lot more information would have been published. he is nowadays getting 30% improvements to cannabinoid profiles compared with his controls. I get stuck around 25% I think. either way we both are better than when he applied for his doctoral certification.

nivek get the original study by doc Kap

Thank you yet again for your information and direction

The first I was exposed to cannabis droughting was around 1980 and it was being conducted outdoors by Apache Indians living across the border. One night as a rare rainstorm was approaching the Indians got out huge poles and tarps to cover patches of cannabis. When I asked why the only two words I got for the answer was "Stronger Medicine".

The plan is not fool proof, but I believe positive results are probable albeit the shorter duration in days to get the desired wilt. Probably around 5 to 6 days will have you plenty wilted but recoverable.

I think it's more differences in how people learn. And you probably drove your first car long before you knew enough to rebuild the engine. Some learn best hands on, others listening to lectures, others by taking notes and rote learning, and still others by teaching. The fact that I learn best by doing and then trial and error to improve things doesn't make that a more or less valid way to your method of trying to learn as much up front and then applying what you have learned to your project.

Different strokes, and all that. I respect your intellectual approach. But I'm also suggesting your audience doesn't all share that style.

I'll go and read the study in detail and apply it to my plants. But first I'll probably go dig thru @Rexer 's and @Maritimer 's threads to find their posts on the subject. I should have bookmarked it when I followed Rexer's grow, but it didn't click for me at that time and I didn't have a plant anywhere near ready to try it myself.

Hey Az! Happy new year brother!
Thank you for the tags.
Here is the link for my drought, at day 1.

Rex's Sponsored Test Of The ViparSpectra P4000 In A 4x4
I have the breakdown in there, and I'm more then willing to copy a "how I did it " over here, if Krissi would like. I don't have the capacity to understand everything in the science aspect, but the nugs from that plant are rock hard, have incredible smell/taste and loaded with trichomes. The LWA was used to determine the progress of the drought, as its easily measurable method of determining the wilting (PS- that app made it a cinch to do).

interesting note,, upon further research,, mr kaplan happens to live in my city,, i know of his companies research,, might give him a call,,ha

The point I was trying to make is that there should be a thread on this that you can just search for the word "drought" and you get right to the ToDo part, in the first post. So, in the future you don't have to go sifting through lots of text to find the basics.

Not that your thread wasn't a great follow! I did enjoy following along. But I'm also super appreciative that you posted the link to go right to it. Thanks, brother. And Happy New Year to you.

Nahhh I'm a positive person! Always laughing finding a new reason to live and learn!

No difference at all and I hope you weren't under an assumption or that I came across like my way is the right way because I will never say that. I am the first person to say to each his own and I know everyone is different and am not discriminatory on any avenue of life and learning

Different strokes, and all that. I respect your intellectual approach. But I'm also suggesting your audience doesn't all share that style.

I hear that and I understand that goes both ways...but hey, at least we're talking about something we weren't before. That's rad.

Honestly, idk if that was a knocking sarcasm but I am going to hope it wasn't cause I like that idea better

Hey Azi,

Thanks and no worries!!!

I get what youre saying- kinda like the low and slow fridge dry. The info is there, but has to be dug out.
Here's why I'm hesitant to step forward to be the one.
1) I don't know enough (and have retention problems) on the science and there will be questions.

2) I'm terrible when it comes to missing alerts, despite my best attempts. I don't know why, but it seems to happen often. And that would be a major disservice to the mission of bringing this information to light.

3) I did it in 100% hydroton. While I personally love growing in hydroton, its not a popular medium. The studies were done based upon soil- that right there would throw some people off.

I will do a how I did it post. I'll try to do the best I can, and will try to have it done in the next few days. And the app I used is called ImageMeter I'm in the middle of building a new system for a winter grow, and those beans need popping soon.

Thank you for investing your time to do that, Rex. I know that many will be grateful for the meticulous manner in which you documented your drought.

I'm sure if you posted your stuff to get it started, others would jump in to answer the science questions. There are plenty of threads around here still going strong long after the original poster has gone away.

I suspect there is still a lot to learn on this newly emerging idea. Your thoughts on various mediums is just one of the factors. I'm sure climate, and indoor/outdoor grows, not to mention different strains will all affect the variables.

Ha! Better get on it. Those beans are not going to pop themselves.

 

[kahoona]

do you start at week 7 with all strains ? if a plant finishes at 8 weeks then where do you start ? count back 11 days and start there or more than 11 days ? do you want them to finish while in drought or just start feeding them again till they finish ? this is very interesting.

 

[Krissi Carbone]

Post in thread 'Come on folks let's see some eye candy! Here's some for ya' Come on folks let's see some eye candy! Here's some for ya

The fruits of our droughted labors.....enjoy your extra dose of trichomes

I'm sure if you posted your stuff to get it started, others would jump in to answer the science questions. There are plenty of threads around here still going strong long after the original poster has gone away.

You are right. We are working on getting some people on board to dedicate some time into a Journaling of droughting in different mediums. It was a suggestion from Rexer and I think it sounds wonderful.

I suspect there is still a lot to learn on this newly emerging idea. Your thoughts on various mediums is just one of the factors. I'm sure climate, and indoor/outdoor grows, not to mention different strains will all affect the variables.

Absolutely. We will all learn from eachother! Especially with having Rex post his medium and I will be doing one for soil for my next plant in a couple weeks; trying to see if we can get others on board for coco and perlite as well...we are all so very grateful for your interest and again, I apologize that it was not set out in a manner in which you would have liked. We are in the midst of working to accommodate the needs of all growers as was the thought initially when creating this thread

do you start at week 7 with all strains ? if a plant finishes at 8 weeks then where do you start ? count back 11 days and start there or more than 11 days ? do you want them to finish while in drought or just start feeding them again till they finish ? this is very interesting.

There are many variables in the length of time and start time for the drought, so I would not lean towards saying there is a level playing field out there for all strains regarding this procedure. Environmental factors play just as much a role in assessing a proper droughting schedule as I would also imagine a faster finishing strain. I generally have about a week or 2 left after a drought. Sometimes less, again not everything goes to the T every time. If I were handling an 8 week finisher, I would probably drought at 6 weeks. Ideally, you would be fertigating the cultivar again and then finishing out however much longer she has. Do you currently have an I week finisher...if so what is it cause I never go under 10 lol...

i have some bruce banner and gorilla glue that finishes in 66 days. with about 10% ambers. i have never grown a pure sativa yet.

 

[Krissi Carbone]

i have some bruce banner and gorilla glue that finishes in 66 days. with about 10% ambers.

Right on. Strong gened plant, the BB....I think under her time constraints she would still do just fine with a little tweak. It is a controlled drought, you know, no need to fret. You can fertigate at any time you feel uncomfortable even with the LWA measurements. Absolutely the medicinal and aesthetic results are phenomenal.

i have never grown a pure sativa yet.

Any reason why? I have a soft spot for them lol
