Hi guys,
My first RIU post hereIve been tralling the forum for some time doing research on growing(ahem,,for a friend of a friend ofcourse
),I have come across this 48 hour darkness thing a few times with a few different reasons to why peoople do it/don't do it.I saw on someones video(cant remember which one)but they claimed they put it into 48 hours darkness to fool the plant into thinking it was dying,and therefore it would produce some sort of chemical to help it to survive?.Like I say I dont know anything from experience here,just bits and bobs that I have been learning on the web for the last month.I will do a project oneday(errrr,,,I mean my friend will,,,,possibly
)as I/he has a perfect stealth closet that is just asking to be pimped out with mylar
.
Anyhow,,thanks to all those that have given info on RIU with their projects and knowledge of growing first hand.

Light and heat break down THC, so I figure that first thing in the morning the least amount of damage is done to those precious thricomes. This is at least how I justify my chopping when the lights come on.
Did he really say that photosynthesis happens at night lol...or did i read this wrong?
Taken from (http://en.wikipedia.org/wiki/Photosynthesis).
In order for the plant to make sugars it requires a light period followed by a dark period. This is why 24/0 veg is stupid. The plant is doing the complete opposite at night time to day..at day time it uses sugars created at night, mixed with water and sunlight to create ENERGY...some of you are thinking it creates sugar from sunlight and water...it doesnt it creates the precursors to sugar during the day time, then at night it uses these to MAKE sugar, which will then break down again during the next DAY cycle.
At night it releases co2 and requires oxygen...during the day it releases oxygen and requires co2. This is because we its NOT photosynthesizing it still needs to create energy to continue to live. So it uses cellular respiration for this...its not efficient at all really, but it is necessary.
So the correct way to get rid of all of your sugars would be to leave the plant in the LIGHT for longer.
That would be cool...if it was true!
EXACTLY lol...deny your plant heat and light and it wont grow...unless you are harry potter or some shit. Be smart and dont post a fact unless you know its a fact...otherwise we will LITERALLY end up like idiocracy... People talking shit about what they dont know is probably how the worlds irrigation systems got to using gatorade instead of water! They even go as far as to say that the REASON they do it is because "it has everything you need". They no longer think about whats in it, and why they drink it..they have been told it has everything you need, why doubt it...they even go as far as to laugh at the guy for saying they need to water their plants with water not gatorade (salts building up in the soil from electrolytes lol)...they laugh at him and say "water, like from the toilet?" lol.
Well you have now been told that plants take the sugars and store them in the roots...if the roots arent hollow tubes (and they arent) where are these sugars stored? like..subspace or some shit. For this reason you have been told to leave your plants in the dark for 3 days.
You have also been told and shown that during the dark period the plant creates sugars, and during the day uses them...I provided links to info you should be able to understand, and the bottom of the wiki page has even more links and info.
If you are embarrassed i just proved you wrong dont get mad and flame me...in the future be worried i will come along and say you are bullshitting, do some research...If your answer doesnt sound right i will spend all night learning if i have to to get the RIGHT info out there.
Also, for interest...adding OXYGEN during lights on will burn sugars even faster. (thats why we need fresh air..or the plant stops growing!) - but if you start burning all your plants sugars things are going to go downhill...if you dry and cure properly the sugars should be long ago "consumed" by the process of curing. (If sugars even make a difference to final taste...)
Cut your plants the day they are ready...my advice would be to do as FDD does...cut branches in manageable sizes, and go trim...FDD has a lot of bud to trim so he cant really be as vigilant as some of us, but handle the bud as little as possible...you dont want all the trichs off the top of the plant wiped all over your hands and carpet and kitchen table lol..you want them on the plant matter.
FDD, my fiancee and i watched your youtube vid of the outdoor grow...she said to me:
"Look! the chairs!! they are always facing the "tree", If i had a plant that big i would watch it too lol."
She also asked why mine were so small >.< I said cuz i cant fit a 7 foot high, 10 foot wide plant in a friggen 4 foot high growbox LOL. <official tree envy>
Also laughed when you were commando style under the canopy...watering or trimming lower growth i assume lol. you were gone in there! TREE HOUSE lol...
We also sometimes drop in to your glass blowing show, just to see what you are working on...I badly want to get into it later on too!

nooooooooo.
stop trying to fix things that arent broken.
if it worked better wouldnt all of us be doing it?
there arent many new tricks to this game so keep it 12/12

I agree with clasonde. I put a couple of plants outside to experiment with what would happen if they received a longer photo-period for the last week. The plants that I put outside appear to be growing normal from the increased photo period, I'm doing this for the last week of flowering for them. What has happened though in the last 4 days made me a believer in the low-temp theory. The nights have been in the 48-55 degree range, the plants responded to this with a noticeable increase of trich production, in addition to turning a deep purple. I am doing this to a third pland and am excited to see what effect the cool nights have on it(different strain).
I'm still undecided on what effect the increased photo-period if any has had on the plant development in its final week, I'm not noticing any male flowers yet, but they've got a few days to go so we'll see what the end outcome is.

Seriously, people are still talking about this? Surely who ever came up with this is out of their mind. No darkness before harvest will do absolutely nothing for your plant, some sick minded individual probably made this up to make you wait just a little bit longer. Like plenty have said before me, if your plant has not produced enough resin come harvest time your out of luck. 24-48hrs will do absolutely nothing.

I could be totally wrong but i read somewhere that if you turn off all your lights 2-3days or outdoors places a plastic trashbag over it for 2-3days the plant thinks its winter and that its dying so it will dump all of its thc to the buds

in a word YES.. a dark period before chop will give your plants a resin boost as light degrades thc, I only go 24hrs pitch black before harvest but have heard good results from those who've gone longer. hope this helps
if light degraded living THC then all your THC will already be degraded. you do grow under lights don't you?
i'm gonna close this thread.

thc levels are highest before your lights turn on. FACT

I ripped this from another board..High Times and other mags say to harvest at the end of the dark period, right before your lights turn on, and that its best to not let the plants see light on harvest day unless its been cut from its roots. In the photosynthesis process, nutrients are moving during the day, and getting stored in the roots at night. By harvesting late in the dark period, you give your plants the chance to clear out all their nutriends from the buds. This method is still helpful even after flushing, as plants will always have some sort of nutrients in them. flamed for trying to help? My mum does work for special needs children so would probably love you fdd2blk
