i am close to the end of my first indoor grow, a massive crop of one plant that unfortunatly went hermi. today is day 55 of flower. about 30-40%hairs are brown/red, others are white or amber. my question is should i do the 48 hour of dark before chop thing. ive seen some people do it on here. lookin for some oppinons. if i understand right, it thinks its gonna die and goes into a bit of a fury and finishes realy strong. thanks for any help

pics if needed are in my grow journal, hit the signature

I was wondering about this too? If it really has an effect or if its just a "weed legend"? I heard 24-36h though...

Been wonderin' about this myself. Would love to see some verified data.

Dark period before harvest
by Ed Rosenthal Should I switch to solid darkness just before harvest?





What do you think about giving plants 24-48 hours of darkness just prior to harvest? People claim this increases THC or makes the plants more "frosty".

In the 1970s, Dr Carleton Turner at the University of Mississippi found that there was a variation in the amount of THC in a sample, depending upon the time that the plant was taken. The most potent point was just before dawn after nighttime darkness.

Then, in 2000, Dr Paul Mahlberg of Indiana University showed that THC was produced extracellularly, on the inside of the glandular membrane, which would allow for its daily recycling.

The idea of using a dark period to increase THC before harvest warrants some investigation. An extended dark period right before harvest might very well increase THC content.

------------

That doesn't really answer the question to most of our satisfaction though, does it? It does howerver imply there is some merit to the "harvest during a dark period before lights-on" theory. Anyone else have any articles, links or quotes on this topic? I'm still curious to know more.

Thats interesting, i have never heard this before and since i am at around this stage myself i figure i'll give it a go myself, at least it will be better for the power bill

i think its worth the old college try, being that you don't have to do anything, except keep the lights off. im going to let my ladies bask in darkness for 36 hours before the chop.


BTW - welcome azrael

I am gonna do 36 hours of darkness just like i did before i put them into flower, and i had a great success with that dark period...

And have only heard good things about both periods of darkness.

I was just looking at a thread from some grower in Amsterdam and he says 24 is alright but 48 can promote moldy buds...so it's your choice...your environment bro....whatever you feel comfortable with
