Total dark before harvest?

Hi New grower here. My 2nd harvest is almost ready and wanted to get opinions on leaving plants in total dark last 48 hours prior to harvest. Looking to harvest on Saturday so should I leave lights off starting thursday or leave them on normal timer. Currently running lights 10/14.

Here is an updated Timelapse of flowering. Explosive growth around week 4 and buds starting to lean over from weight at the end.

It's not the lack of light. When the lights are off the temp drops which in turn makes the humidity drop making the air dryer. The leaves sense the air drying and will increase resin/trichs and that is why people do it. Frankly though, if you're not satisfied with the output of resin, two days in the dryer air is not going to make a huge difference when compared to growing it right through out it's life.

Yea and no to that answer in my opinion. I would always have lights of for 36-48 hours but still leave all you fans running full blast, All the old growers and new alike use this practice, It helps to finish the plants off, slightly increasing calyx and flowers density.. try it. no harm.

I have a dehumidifier and already dropped RH to 45% about a week ago also raised temps a little. Fans always run day and night.

You could leave your fans on full blast and that will further lower humidity which is why it works. What he said ^^ it's more about growing it without issues through flower. That is going to give you better results than trying to make up for it in the end.i tried it once and I didn't see an improvement.
 
it seems to make a better tasting bud when i do this to pure indica strains that have only flowered 7 or 8 weeks.plants that flower past 9 weeks didnt seem to be as affected when it comes to flavor.

I'm sure someone will chime in with a bit more science to the question, but who knows :)

Don't bother with a dark period before chopping its complete and utter bollocks imo

Wrong...

For one, plants send all their starches (food) to their roots during the night. As soon as light is introduced those starches are brought back to the above ground portion of the plant.

Do you want to be smoking that?
:tiphat:


I seem to remember seeing a similar thread in the "harvesting & processing" forum. ;)

The 48 hour dark period only works if also have the required naked maidens dancing among your plants to the beat of a marimba band. Get your bro science straight or get out of the profession :tiphat:

If i am wrong you can obviously prove it by posting some peer reviewed studies to back your claims up ? Personally i think you are talking out of your :moon:

Please don't start a Pissing contest.

MJPassion I think you were confused. This thread is not about harvesting before the lights come on. I already know I need to do that. It is about whether a total dark period for 48 hours prior to harvest helps or not.

Thanks for all the replies

Not my intention to start a pissing contest.

However,
I'm not about to spoon feed somebody just to appease them. Especially when they can in no way substantiate their claim.

As far as your original question,
You will prob get mixed opinions due to the rather non scientific nature of the way folks measure things.
I'm not sure that the answer you are looking for has been tested in a lab, therefore, answers will be subjective at best.

Hope that helps.

If you've got two plants of the same cultivar put one in the dark & judge to the best of your senses.

Spoon feed :moon: lol people saying that a longer dark period before the chop will increase resin production are the ones making the claim so they and you saying as you agree and said i am wrong are the ones who have the onus on them to post evidence to back up their claims not me :laughing: and given you have just admitted the scientific evidence does not exist i don't know how you can tell me i am wrong . so its quit clear who is talking out of their arse AGAIN :tiphat:

I hav done a dark period many times, now w a perpetual I jst shut down half the lights. So it's not a total dark sort of thing any more.

I picked it up reading along w Bog's grows n it seemed to make some sence.
What I figured is that a bunch of things could b happening but I'm no scientist so I only have anacdotal evidence.
My grow runs in the low 80's during lights on, n I fig it's good to let the terpenes reacumate in cooler lo stress conditions befor the chop.
I do think it makes for better tasting and easier buring buds.
And I belive it makes a diff w starches too.
If I go a day long n they sit for a third day of harvesting, the plants feel noticably softer and not awesomely dense like usual. So I highly recamend agents this!
I hav not done comparisons but I'd bet that they weigh less if given too much dark.
 
i do a perpetual harvest so i take my plant when its ready to harvest and go move it over a few rooms to a clean dark closet an leave it there for 48 hr.i can fit 2 big plants in the closet at the same time which helps because sometimes i harvest 2 at a time
 
ive done bud side by side 1 kept in dark 1 not of the same strain white widow,and the 1 that sat in the dark def tasted better.
