18 hour light during end of flowering

THis is simply not a good idea. What ends up happening is you force the plant as many posters have said back into veg. However, this is only part of it. What ultimately happens is physiological. One day or two wont hurt the plant. But three or four in a row will cause the plants stomata to ultimately stay open and not close. This is not a good thing. Further, the overall trichome will begin to degrade rapidly. The plant will begin to use up stored sugars because glucose should not be in a plant during such veg. This starts a downward spiral. It also lowers the immune system of the plant. Monster Crops are prime victims of PM, rot, and other issues. You can try it. But its a complete waste of time/ money / and energy

SMH? WOW, that’s is really selfish dude. Reread that to yourself and think about if this is the forum for you. We are growing and learning with a passion. Cut it out, your like a cancer!! We will find the cure bro.

from my experience. After 48hr trichome started to fall over very slowly 52hr they completely melted into lil brown globes and the sugar leaves started to get shiny and wet looking. The smell was foul-er the humidity went nuts. The red hairs turned brown dried up and the fan blew them away. Too wet, too hot and humid. Moisture +Buds started weighing down the thin branches. I put her down. The smoke was very strange. It smelled as if it had seed, but not a one was found. No one had a clue. It was around the holidays so all my visitors and neighbors got a chubby chunky 1/4. The next morning I woke up to my bowl and wife’s car tires slashed. Then it hit me!!!!! The neighborhood caretaker!!! I’m sure he felt the the hit. So I sent him $100 bucks and some beautiful bullshit. He didn’t know it but he ended up paying 2x the cost of the damage done to my wife’s car. I’m not glorifying negativity, there is a valuable learning experience buried in all that Babel.

Just incase anyone decides to reveg a keeper after flower, repotting to a bigger container does help rejuvenate the veg growth faster. But give it a few weeks first to recover, if it can, and leave as many leaves and branches on as possible along with a little bud growth. 24 hrs light helped on the ones i've done.

that or you need to cut some roots, new root growth is critical to new reveg

Your attitude is all wrong here. YOU need to make these mistakes so YOU learn. If I give you all the answers you miss the underlying reasons. That's not selfish, I don't owe you anything. I still make mistakes growing. Don't expect other people to do your work for you and don't be a Nazi, prove me wrong and post it. Then we all learn. You are the uneducated cancer, spreading poor information, and expecting from your host.

don't run 18 hr cycle 3 weeks from flower,i do that the last 10 days of flowering,i also add 6500k daylight the last ten days.it also increases tricomb production.you have the right idea but 3 to 4 weeks from flower,your asking for trouble like hermies,little buds and we don't want that.iv been doing this way for 5 yrs and allways have a great yield,10 days max from harvest.start this process.keep it 12/12 up to 10 days b4 flower

I have given plants 10hrs of.dark and the buds did ripen much quicker. I norm do this last.week when flushing and raise the lights wen on.....

The longer the dark period the quicker they flower, but a quicker flower means less time making buds so less yield...

Does no one read ?? R c clarke covered this....

But thats inexact maybe.. .. floragen is made in the dark cycle which help the buds production and become bigger. But yes if you cut too much light time than you cut photosynthesis. Look up for 12 on 13 1/2 hours off or 12 on 16 off. But if you dont have the right balance like every other aspects for cannabis environnment.

So alot of people do 18/6 now the last 10 days of flower. So has this thread been debunked yet by science? Seems like a lot of science was talked about but never supported by resources...

Who does this?

Was it this idiot ?

I do this.
Never a hermie. Just better buds.
I change to 18 hours the last ten days of grow.
A Breeder Rasta Jeff turned me on to it.
your plant has been building hormones in flower for months. It takes approx 14 days or more for the hormones to “change” enough to build and overtake the flower hormones to effect the plant’s morphological.
I get better yeilds, and better grows since I’ve adopted this growhack. It works, extremely well.
Of course, there are most who are stuck in their grow styles and never want to explore and adapt.
18hours in last ten days of flower has been one of the best adjustments I’ve done to my grow style.
it’s not for everyone, but those that do, love the results.

for those that are not afraid to learn:
Podcast episode #591 of Rasta Jeffs “Grow from your heart” podcast talks all about it.

grow on Have fun
Peace

How powerful are your lights? I have to dial my lights back the last few weeks to keep the flowers looking nice.

Pepe is right. Take flower back to 18 hrs and watch it go back into veg. Very rarely will it finish with 18.
