resin production more at night?

I heard that resin is produced more at night, people I know who have grown autos said give them 48 hours dark before harvest, any reasons behind this, didnt get round to asking them??

actually all plants grow better at night, in all processes..what happens is....during the day or light hours your plant goes through whats called photosynthesis, which is the plants way of making food with the sun...all day it collects this light and turns it into food...when the light goes off or the sun goes down..the plants "eat" the food, or grow...that make sense? and as for turning the lights off 48 hours before..what that does is turn on the plants natural instinct, and tells it that its now "winter time", and its about to die..so what happens is the plant puts out all of the possible energy (food) it has left and drains its leaves and stems of all nutrients to put them in the buds so that they will stay alive longer and produce more resin and bigger buds before they die in winter....indoors there is no winter so you are tricking the plant to think so...thats the whole idea of indoor is tricking the plants into thinking its the time of year you want it to be...ie, veg, flower or harvest

I don't agree, 12/12 is more than enough to trigger flowering. Yes they grow more in the dark period but its the 12hours of light that gives them the energy to produce the buds, so a 48 dark period you lose 24 hours of energy drawn from the HID lights. Outdoor there is no 48 hours of dark. Also a long dark period encourages mold and changing the light schedule can cause hermies. There is also no evidence long dark periods make dope stronger.

Plants don't grow faster at night. During the day, it converts excess sugars into starch, and at night it burns this starch.

The reason it makes sense to harvest after a dark period is to reduce the starch content of the final product. At night, the plant knows exactly how fast it can convert starch into sugars for growth such that it has 0 left after the night period. It does this by remembering how long the last night period was.

If you leave the plant in the dark for longer than it's expected night length (what it got yesterday), it will go into a starvation mode. Keep in mind that since it bases how fast to burn it's starch at night based on yesterday's night length, increasing night length toward the end of your grow will not have any effect on the results. The plant will just burn starch slower at night to compensate for the longer expected night.

I don't agree with the theory that it causes increase resin production, or a last burst of flowering. It's just a way to increase burn quality of the final product.

thats not at all what hes saying...duh 12/12 is enough for flower..lol..that the only thing for flower...hes talking about the last 48 hours before chop..and yeah, there is no 48 hour of dark in outdoor..thats exactly why indoor is better..lol..you tell the to do exactly what you want for as long as you want to fully optimize the growing..outdoor does everthing itself

O.P. said the last 48 hours, not in the beginning or middle of flowering. I know many people on this forum that have done this and they will tell you it improved the flavor and smell of the buds as well as make her a mighty sticky bitch.

If it weren't the very last 48 hours, I personally wouldn't do it. But I see nothing wrong with the end.

yes, plants do grow more at night....they grow way more at night infact..id suggest you do some more research on the way plants work, it really does help with growing anything...and again its proven that when you turn the lights off for longer than they are supposed to..they think they are dying or going into winter, the starvation mode youre talking about is this process where they push all their nutrients to the buds to get everything out before they die

Haven't seen you in a while! Interesting-- I've heard THC is produced at night (or in the dark) and that that's why a lot of times there will be really frosty buds in shaded parts of the plant. I'm sure this thread stems from the same school of thought.

As for my experience I've got an aeroponic setup going. Suuuper fast growth, compared to my soil. I veg with a long photoperiod 18/6 but in my experience I've not noticed faster growth at night.

I mean sure, I've checked them at night before lights, and come back the next morning to see that they have shot up overnight. But its nothing compared to the growth during the day--i went to the grow store like a week ago; checked my aero plants before I left, no buds, just sexed (which it had been for like 4-5 days and hadn't started growing buds yet). I cam back that night and checked them out, and I'll be damned if they hadn't grown nugs in that single day. It blew my fucking mind.

Churchaze, does lower starch content provide for a smoother, more flavorful smoke? I thought the carbs were what gave the plant taste? I have tried the 48 hours (and much more) before and have definitely noticed a difference in final product.

And to BUDS, it seems like you are maybe thinking that he's talking about 48 hours of darkness before he puts it on 12/12? He's just talked about putting the plant in darkness for 48 hrs right before you chop it.

if you watch your plants during lights on...they really wont grow much..you can hardly tell..but once the lights go out..if you check on them periodically you can actually watch them grow..and if you check them at the beginning and end you will see quite a bit difference, you can really tell the most if you are growng from beans..i Just planted a new round 7 days ago, yesterday all my seeds were still underground when the lights went off, when they came back on they were all over 1", i know they unfold from the seed, but still i think thats quite a bit more growing that during light...it has to be, becuase they are using all the energy the stored during light

18 hours max not 48, but I ain't that cruel, my flowers and I have done the journey, come harvest time put them down in a style that is appreciative of your time and efforts ...enough of this greed bullshit

No it isn't. Even when the plants are budding, even under 10/14 conditions even longer night, the plant still won't go into starvation mode. The only time this happens is when the night is longer than yesterday by significant amounts. If the plant expects the night to be 12 hours long, it will use all its starch reserves in 12 hours. If the night lasts for 14 hours, it will have 2 hours of starvation mode where growth stops. Starvation mode isn't where energy is pushed up to the buds, it's where it has no energy left and is trying to stay alive.

Iodine starch tests on leaves after the light period ends show black, meaning lots of starch, while iodine tests at end of night do not turn dark showing no starch left. I'll post pictures later, I'm about to do something else now.

lol..growth might stop if you turn the lights BACK ON after you change the light cycle...you do understand that he is only talking about the very last 48 hours before he harvests right? it is proven through scientific tests...and you can see it yourself if you try it...48hr before harvests increases production, makes smell and taste better

So if you leave plants on 24/0, they will never grow?

I said they wont grow much..not they wont ever grow lol..they will grow, but not for shit..they might grow decent for a week or 2 with seed and wk 1 veg...but i guarantee if you left them on 24/0 for you entire veg, and did 18/6 for a different veg..100% positive the 18/6 would have WAY better growth

using 24/0 is usually used for beans, and its 24/0 because they are under the dirt, they are always in shade, 24 hours or light helps them push to the surface supposedly, but there i prefer 18/6

No way are you going to veg faster under 18/6 than 24/0.

Ummm I get super dank on exact opposite 6 hours daylight and 18 darkness. I get like 3ft tall colas and as big around as a coffee can. In a 2 gallon pot

Yeah, starch sucks in the final product. Think of bread. Over time it goes stale, hard and crunchy. Without starch, weed should crumble up in your fingers when dry, there's nothing to go stale, and because there's less mass in starch, a greater percentage of the product is resin.
