I have access once a week, occasionally twice a week. All plants are now in flower time, some way ahead of others.
I am not familiar with Caplan’s work, so depending on pot size one can assume evaporation + plant uptake of water can be faster? I have small pots for the clones, the moms have 30gal pots.
Thanks Mel
I’m just looking at a avg timeframe people that have already tried saw results. 7 days without watering already sounds like a lot, enough to make drastic changes.I have several plants from same mothers but slightly different setup, I have around 9 clones 5 of them are in pots and the pots have different sizes, I also have 4 same clones in the ground. All have been watered heavy (6 gals divided equally) once a week for the past month at least, during August we had several weeks with out any rain and high temperatures and very low RH, the 6day “drought” effect has been on going. I have stress them as much as possible without killing them. I guess I’m wanting to know if droughting only count for the last week of flowering or is it something that can be done all thru flowering.
August drought
Today
May I add this became a breeding experiment since one of them is a male.

Thanks Lerugged! If you smell some really sweet fruit, that's the Purple Urkle.
Sure is something, just not sure what!
Here is the link. It's not all that long for a research paper:
Increasing Inflorescence Dry Weight & Cannabinoid Content In Medical Cannabis Using Controlled Drought Stress
Because linking to pdf files is currently prohibited, research articles and scientific publications cannot be directly accessed by folks visiting this site. Therefore, I've decided to post the research paper titled above by Caplan et al. as images in this thread. I will be requesting that this...
www.420magazine.com
Since the only actual science we have is Caplan's methodology, that's all we really know for certain. I don't think that depriving a plant of water while it's trying to produce flowers would be helpful in increasing THC, as it hasn't even created much in the way of trichomes yet. Seems to me that the reason for the late drought is that everything is already in place development-wise to allow the plant to focus on the protective response of increasing THCa. Pure conjecture on my part though, and what you did was all you could do for your plants.

Thanks on the paper I am already on it reading.
The Flowr company I know the company from the Canadian stock market, Im surprised to read Caplan worked with them at the time of this research.
It’s said controlled water stress does not affect yield but it doesn’t add specifics.
“Drought Stress
Let your plants wilt slightly in late flower especially around week 7 to increase cannabinoids and terpenoids. You might worry that cutting back on the water would limit your plant’s growth, But Dr. Caplan found that a little water stress during the flowering stage doesn’t affect your overall yield when you harvest. Water stress also goes by drought stress and is a slight water deprivation that can improve overall potency of cannabis buds. Do not let your plants dry out and die though! There is a difference between allowing the substrate to dry out and letting the plant dry out. Each strain will deal with different levels of drought stress differently.”
It’s hard to replicate Caplans exact experiment but it’s good to know that there is a measurable increase of canabinoides and terpenes.
I can’t wait to see yer smoke report it will be interesting to see how much of a difference that it has. Happy growing CL

I can tell you one thing, they all look different already. I can’t wait to smoke them all and see differences or not lolI can’t wait to see yer smoke report it will be interesting to see how much of a difference that it has. Happy growing CL
We're all in agreement that during the last few weeks the buds do a final swell and put on weight.
It would seem like that's the time where they need water the most.
I'm not saying droughting doesn't work, I know it does.
But it's a bit contrary to the above given most strains finish in 8-9 weeks.
Perhaps we're trading a bit of weight for THC production? JM2C.
Sorry for just barging in, Shed lol. Back to lurking in the shadows.

Let me know if ya need any help smoking them.lol
Dani, I found this before we started looking at Kaplans work. At 1:52 the twins get to talking drought. Lose the () after you copy and paste. Just something to add to the party.

Just saw that, so they do it right before chopping 3-4 days with minimal water. Interesting. It seems very experimental listening from them, Caplans work is a little more detailed but feel they still holding on information.
Seems like most of the information doesn’t say how long does it take for a trichome head to fully develop and swell to eventually burst. It makes sense to do it a week before harvest so the risk of losing the whole crop to drought is very minimal.
Thank you for sharing Stone
Looking beautiful Shed! A few of those pics up close were spectacularly gorgeous
Question for you and everyone.
I'm looking for the best recipe for a topical salve, specifically to help with extremely severe Arthritis (for a family member). Poor guy's hands swell up like no tomorrow. If anyone has a good one, that they can vouch helps, I'd be grateful.
Thanks!

They might be being cagey on the subject since Caplan may not have wanted the info out there before he published? And his findings really are not "a little water stress" so I'm not sure they even read the paper.
One thing you will find out is that you won't know anything about the difference drought stress makes.
That's the anecdote part, and plants from seed (even from the same pack) can be very different.His finding was that there was no statistical difference in harvest weight from control to droughted.
Anytime Regrowth, post away!
Thanks Rex.
I can help there as I used to make loads of topical pain meds. Here's what I can tell you:
CBD and THC are not absorbed into the bloodstream using our standard oil-making methods.
Because of that, pain deep inside a muscle (like hip arthritis) won't be touched by topical oils. Of course massage always feels nice!
Best place for topical oils are hands (like your fam), toes, elbows, and other place just below the skin.
The other best place for them is the spot where your spine meets your cervical vertabrae, called the Medial Dorsal Rami (MDR) explained in my post here. From a video on the Green Flower Network, that is an area where the never ending move from the spine to the neck and are close to the skin. Additionally, it's an area where those nerve connections are unmyelinated, meaning they don't have a covering on them and may be more susceptible to the effects of the oil.
Applying oil to the MDR can deaden pain signals from anywhere below that spot.
The most effective strength for oil is at least 15mg/ml (calculated roughly using OldBear's spreadsheet...PM me for a link and instructions), and in my house it seems to work best when applied 10 minutes after a CBD topical at similar strength.
Variety doesn't seem to matter, only cannabinoid content, though I haven't seen any research on what role terpenes might play in topicals.
In terms of the oil to use, don't use coconut or olive for pain topicals as they sit on top of the skin and don't allow the cannabinoids to penetrate at all. Use something easily absorbed like grapeseed. And ideally, just use flowers and oil with no additives like shea butter, waxes, etc. as those will also tend to keep the oil above the skin.
If the smell is a problem, essential oils can help with that.
Let me know if you need instructions on how to actually do the infusing if you don't have a Magical Butter machine.
In terms of inflammation generally, CBD oil taken internally will begin to decrease inflammation after about two weeks. My wife takes Candida capsules 3x/day for a total of 30mg CBD for the arthritis in her big toes.
[Note: all flowers are decarbed before making oil for internal or external use]
Wow, your really up on that. CoolThey might be being cagey on the subject since Caplan may not have wanted the info out there before he published? And his findings really are not "a little water stress" so I'm not sure they even read the paper.

This is all very good information and I didn't even know about some of it. Thanks for sharing, Shed.@Rexer - You can check out Magnus' Topical Thread too for more in-depth information.

I'm there with you, I got several there with deficiency and/or nutrient lock out, they probably have root bound stress and drought stress too. They are somewhat neglected intentionally as I am trying different things in terms of phenotype structure and hoping to make some seeds now that I have a male.

Monday update, leading off with some trichome shots from Friday just for fun!
Both plants were on flip day 59 then, and here is the Trainwreck from @Weed Seeds Express:
And dig the purple trichome stems in the next two pics...never had that before!
Here is the Purple Urkle:
Zooming out a bit, there seem to be quite a few spotless ladybugs on the plants noshing on the aphids I haven't sprayed for, though mostly on the Purple Urkle (btw the brown and burned leaves on the plants are from the heat wave we had in the beginning of September - no cause for alarm):
One is on the Trainwreck though:
Speaking of the Trainwreck, remember I mentioned that it had supercropped itself from the weight of the tops? Here are pics of the bends (pardon the blur on the second one):
It's been a while since I pointed this out, but here's a good way to see if your browning leaves might be budrot. This isn't:
How do we know? The leaves are brown from the tips in and not the inside out:
Both plants have slowed down their water intake but still not ready to come down. I'd say one will get the chop this weekend, though I'm not sure which yet.
I hope you had a great first fall weekend and your preferred football team came away with an moral victory if not an actual one!
Stay safe out there, and a happy new year to those who celebrate.

Thanks mumps! I usually top above the 8th node, and both of these were. And if you're trying to count from the bottom up, the first two nodes have been removed and maybe even the third. The lower nodes make the plant too wide to fit through door every morning/night.
Free seeds are a great bonus.
