Droughting and its medicinal effects in cannabis

[nivek]

wow @Krissi1982 ,, impressive indeed,, that is a job swell done,,

i have started a bit of a project to learn a bit more about how long my plants in their hempy state can actually go without water at the stage they are at now.

the plant was planted nov 08 but that is not a true representation of it's age because it sat in a solo cup for near six weeks before it sexed itself,, so,, i will just say the plant is about maximum veg state for me,,

i fully fertigated it today at 12 noon precisely,, and the pic was taken four hours later

the black line gives me a fine vantage point to watch and measure the affect

it shall now sit neglected until leaf wilt becomes apparent

the black circle just circles my branch marker

also,, if one wants to see a classic example of nitrogen claw,, there it is in blue

these sativas take so little fert it's easy to over do it,, and using mega crop,, i have no adjustments available,, tho i added a bit of cal/mag to a slightly diluted mix today

will update in 3.67 days,, karma sent

I'll be waiting to the 33rd percent! And thank you love my girls!!

Cheers to good droughting Nivek, these were the flower tent girls just now. They like your positive vibes

Trich shots post drought, G...
Short on time tonight but wanted wanted get these out here friends

@Maritimer

 

[Krissi Carbone]

You saw mine now let me show you some of my mentor's....

2X batch of drought affected trich shots for you guys today! Luuuuucky!

Wow! Those are much more dense than I'm used to seeing when I look through my loop.

I may have to try this.

Thanx Marcus Give me a few more years when I finally retire and I'll have more time. I started at week 8 and went 8 days drought but got scared ! Pretty sure I could've gone 10 to 11 days tho . Thats how we learn tho

You will get more comfortable as time goes on friend! No worries! Looked fantastic

out of curiosity when are you measuring this leaf angle ?

i ask as a plant in flower should get a dramatic droop daily if it's lit proper. i'm trying to figure out what you're actually looking at. i'm assuming you're looking for a lack of lift rather than a droop, so no praying hands in the morning.

 

[bluter]

also wk 7 is the wk you normally get the bud swell and an increase in trich production if you are growing correctly. i'm not sure you can attribute the effect to the abuse.

As often as I can throughout thr drought, about 3x a day I check because it can drop really fast. Not nearly as subtle a wilt as your typical sleeping plant these are dead looking wilts.

Yes it does fall into late flower timeline with bud swelling and increase but this takes it to a completely different level. The study has the proof in the pudding but for those of us who have used this process, our buds have no comparison to the buds we harvested without droughting. Crazy medicinal effects

you sure it has nothing to do with the fact you've been upgrading and getting better as a grower over the last 3 grows ?

i changed lights in the jungle room a couple grows back and tripled my output. i know that's what did it as it was the only factor changed.


edit : also i don't see how this can be accomplished in any media other than a soil. hydro implicitly means water present at all times. you can suspend feeding in passive, but not active hydro, and stuff goes downhill fast in passive if you do.

Not sure if you mean soil specifically or not because the study was done with plants in a mix of peat/coco/perlite.

yeah i kinda did. mostly as the water retention in those three are less. peat and coco will retain, perlite will wick but not retain.

which also calls media in to question. does the drought need a specific mix, or can it be accomplished in other mixes and media ?

 

[nivek]

does the drought need a specific mix, or can it be accomplished in other mixes and media ?

well now there is the question is it not?

let me suggest this,, instead of looking at the differences between soil and other substrates

look at the similarities instead

edit,, heya friend,, not sure if you have read the study, or want to,, but this is scientific proof that this works,, no pseudo science here,, the real deal

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...

being a hempy fella as you are,, and with a wee bit of experience under your belt,, perhaps you can help us figure out how to faithfully replicate this study in mediums other than those used in the study

well it kinda calls for suspending feeding right at the 2 wk bud swell. i'm not sure it's worth risking in hempy.

once a root system dries out far enough it won't come back in a media as exposed to air as hempy is. also i'm running root locked through most of flower. it becomes almost a shoot to root system.


edit : this isn't to say there is no validity in droughting. i've seen something similar but outdoor. i'm not sure it equates.

How about using less water per fertigation, or adding an extra day between waterings if you don't water every day? The study seems to suggest it is not only the amount of draught but the length of time it occurred over.

 

[Emeraldo]

But I counter that study with literally thousands of years of studies all showing hugely negatively effected plants and trees from drought. You can even see a drought year on tree rings because the tree grows less. It doesn't suddenly get stronger because of the drought.

It has been established that the famed violinmaker Stradivarius made his violins after a severe drought in the 17th century. The annual rings in the wood in those violins are very close together, giving the wood a resonance and strength that produces a rich, voluminous sound unsurpassed in quality. It's directly caused by the lack of water.

I don't know if there is a similar benefit to droughting in cannabis plants, but if there is, it ought to be measurable as a matter of objective fact.

It's a worthy topic. Am looking forward to hearing more.
