36 hours darkness before harvest...truth or fiction?

[highonfire420]

Well I have done the extended darkness period and have to say that I did notice an increase in resin. Now I am not saying that was the reason. Could have been a good grow and strain that pushed it out.

I have read many write ups on this. Some dispute, some swear by it. I guess I am looking for some people who can add into this theory.

Turning your lights out 36 hours prior to cutting the babes down.......tried it? Don't think it works? What are some of the thoughts floating around on this. Maybe no thoughts on this issue. Just felt like throwing it out to you.

Will be doing it on this grow right now.

[dredank]

Dont know if it will work, but ill try it sometime:D
:peace:

[CB]

try 96 hours sometime :eek:

[highonfire420]

96 hours :eek: indeed. You do this Cheap? I am wondering if it helps in the breakdown of wanted shit before harvest at all.

dre, if you do let me know. This really intrigues me even more after hearing 96.

I am going to leave 2 in the room for an extra 36 hours darkness before I harvest them and see if they have a noticable diff to them. Not sure I could handle the 96 hour period :D .


Keep it green.

try 96 hours sometime :eek:


I would be worried about mold if I left them in the dark that long.. be very careful if you try this..;)

Maybe if you keep a fan on them you reduce your chances of molding:D

[CB]

yes I have done this but not all the time

cel has allso done this except i think he went a bit more than 96 hours....

will see if i can get him in here to share his outcome :D

never had a problem with mold myself

[Bender]

never had a problem with mold myself



I am the mold king..:o

But I'm not going to hijack this thread.. I just wanted to point out that if you have problems with mold like I do, that 96 hours in the dark may not be the way to go..;)

5 days of total darkness for me, on a shiva shanti grow,
didnt water them during that period,
all the hairs were red and 99% of the buds had matured with atleast 30% more trichs.
Mind you, i did 5 days of darkness out of necessity, because i wasnt home at time, but yes, CB advised me, and i reaped the rewards ;)

Thanx bro

This much I know the glycogen (sugars) are broken down and produced durng the dark phase.

If you have no plans for the plant after the longer dark.. all it will do is break down those sugars colected during it's last light phase. As long as you harvest after the extended dark phase (btw which is what jar curing is to an extent) it should "sticky up" the buds real nice. I would be concerned if I had to re intiate the plant to a light cycle.. that wouldsend a very weird message to the survival genes of the plant. (can you say hermie)

Will the plant die?

By the end of flowering my plants wanted to be watered like everyday, or they would get really dry.

What kind of health effects does doing this have on a plant? Physical effects?

[bald1]

Hey Gorilla,

All that would mean is the plant would start to dry out like you want it to anyways ;)

I have tried the 48hrs darkness and didn't notice any difference in a side by side test with a strain I have grown for many years. One went into my other shed for the extra dark period, and the other I chopped and put it in my bud box to dry.

After both plants were ready, I couldn't tell any decernable difference between em, they both had me on my ass :p

peace,
bald1.

say G-mang,

what size pot ya use'n that ya have to water everyday in the end of flower?

[gorilla]

what size pot ya use'n that ya have to water everyday in the end of flower?

Hey pal. I had nearly 4 foot tall plants in 1 gallon pots.

[CB]

Hey pal. I had nearly 4 foot tall plants in 1 gallon pots.

cool same size i had last grow but temps where a bit low so got away with every 3 days :p

gonna use 5 gallon this time as temp's are on the rize here :(

like bald1 says it's gonna start drying out... no harm done ;)

tiss what we want in the end :share:

[gorilla]

True, okay. So a plant is technically still alive, even after days and days in the dark with no water. - Pretty impressive.

I also hear that a slow cure/dry in a dark place produces the best smoke. Do you think this extended dark period is really just the same idea? Or is it really making the bud more potent and/or more well done?

[ice#1]

this was taken from the nirvana boards and they grow a few of the white strains
You will probably read or hear from some where that you can do certain thing's to your plants , to increase THC , example : like giving them an extented dark cycle ,,,


Untrue. This is another myth perpetuated by the notion that cannabinoids flow within the plant. They don't. They're produced at the site of the resin gland. A plant's life cycle is measured in months.

Any significant changes in the plant occur over time. A 24-hour dark period just before harvest will have no affect at all. It's another in a long line of myths about increasing THC production just before harvest with some special technique.

Others include hanging the entire plant, root ball and all, upside down to let the THC flow into the buds, or boiling the root ball for the same reason. The best way to produce maximum resin is to provide the best growing environment possible, and to practice good harvesting, curing, and storage techniques.

11 dark /13 light , for the last 2 or 3 weeks of flowering stimulates better & tighter bud growth & is highly reccomended , but that is as far as it goes ,,, from there on it's genetic's ,,,

you will probably also read somewhere that when growing white .widow or white strains , the lights should be cut down to 8 hours 1 week before harvest so that the plant gives up every last drop of THC they say ,,,

this is also a big sack of bullshit & these people that say these thing's should be whipped with a cannabis stem 2 inches thick ,,,

There is the method of putting your plant's in 48 hour darkness right before chop down to increase resin production & to speed up maturity ,, this is true , and grower's should try it ...

peace & happy growing
it's kind of double talk but he states it won't work in the first post then states in the second that it does work so who knows

[rangerdanger]

I've seen people recommend everything from 24 hrs. to 2 weeks[B] total darkness before harvest. I saw pics where someone had taken that 2 weeks advice and the plants were a [B]MESS.
The advice that stated that cultivation of pot takes months is spot on. For that reason, I think those agruments about exactly when to harvest--start of light cycle/end of light cycle--are meaningless. The difference would be so miniscule it would make no difference.

[vernonsupreme]

i believe he was stating that the point isn't to increase thc but to increase maturity rates and resin production.

I have done dark periods from 1 day up to 2 weeks and noticed a decline in vigor after one week from the lack of photosynthesis taking place. especially in white strains the 3-7 day dark period really makes the buds crystal up.

[rolanterroy]

Certain strains this can have an AWESOME effect on, not THC as far as I know but in the Bag Appeal dept. and I ain't kiddin' around here either man! :p Some of the real olden White Widow, Durban Poison, Oasis are a few that come to mind. A 7 day dark cycle just before harvesting; a key factor here is that temps and humidity must remain the same and only water, or a SUPER mellow nute mix (like 1/4 teaspoon per 20 gallons mellow) in the case of hydro should be used. You just need the slightest amount of nutes available to the plant for this effect to really kick ass. In soilmixes in straight up darkness they can go easy 7 days on a good watering with lights out.

It's also very important NOT to inturrrupt this darkness cycle for ANY REASON or hermies could rear their ugly heads.

The final product of the right genetics done this way is nothing short of astonishing fellas. Looks like buds from Pluto or something I shit you not.

I never bother with this anymore, but back in my cashcropping days indoors we would do this often and it would command ASTOUNDING street prices heh heh.

[billo]

ive read about this at another site
atm im trialling the 72 hour theory
and have 1 plant in a cupboard for the last 36hrs
i flushed her thoroughly for a week
then give her 1/2 a flush prior to putting her in cupboard
not really the beast plant to try this on as its very leafy
but i accidently interupted her this morning
peace

This is what I've come to believe as well. I tried the darkness thing and didn't really notice any benefit to it. With my current set up it would be a really big hassle to try and do this unless I bagged them. I just chop when they're ready, no darkness anymore.. No problems this way..

There is no glycogen in plants just in animals... It is amylose and amylopectin. The dark cycle is the time when these are broken down and utilized though.

[suougibma]

I use to do a 3 day dark cycle and swore there was some improvement in resin production but since splitting my crop in two halves i don't want to give the 2nd set that much dark in the middle of their cycle...
