7 days of dark. The final flush.

Smoking good weed tends to make folks friendly.

Let's not derail another thread with useless fighting and flaming... Keep posts relevant to the topic, we are here to discuss not argue. Any attacks/insults will be deleted. Play nicely everyone!

I posted this to help you!! I just wanted to help maxamize your trichome coverage! If you dont want or need the help then take off hey. For those that want stickier buds, FOLLOW DIRECTIONS ON POST #1.

Control group? Overall THC testing results?

Youre totally full of it bro, just cos you "think" 7 days dark increases tric number doesn't mean it does. There is published results from a study that say more that 72 hours is a waste.

Also in the dark if you water, because it's colder their can't absorb as much moisture, giving you a higher relative humidity.

And you cannot flush organic soils, and more to the point, flushing in soil is a joke anyways.

Mull that around the grey matter for a while, as much as you may want a fat rep bar, you won't get it posting myths for noobs to follow.

EDIT: Purple strains are for noobs btw

The way salt based nutrients (chemical ferts) give your plant nutrition is by skipping the whole process of microbes exuding food and going straight to the roots. Obviously what is not used by the plant is then left in your soil and acts as a build up that can be used later. Most of the time this salt build up is unwanted though and that's why flushing became common practice. So flushing in soil can be useful if you load the shit out of it with liquid nutrition... otherwise, not too necessary. The way THC works is like a sunscreen. The plant puts it on in the dark period as a response from the light that damaged it during the light period. That is why people argue about an extended dark period prior to harvest. I don't really know how helpful a week would be though. Ice water doesn't force any trichs to come out. What it can do is cause the roots to become too cold to uptake phosphorous which causes a deficiency and turns your bud purple. There are better ways to achieve purple buds, like just lowering the night time temps... but ice water for the last week won't really cause any big problems and you'll get purples, which people love.

hummmmm......... very interesting, i typically do a 3 day dark period b4 harvest but it does seem a little at odds to the current arguments around UV-B lighting which claims that THC is only being created as light is being absorbed and that THC may be a byproduct of other chems reacting with harmful light.


Who knows????????

to clarify.... "some" evidence seems to support the idea that THC may not be a sunblock but the byproduct of light reacting with other chems (i can look up the scientific names if you need me to) that act as sunblock. sorry the first part was worded kinda poorly.

again this is all just from reading..... mostly on this site..... i have not tested any of this only researched it.

It seems to me that after 72 hours of darkness, the plant would have used all it's light cycle energy stores. Where's the energy coming from for these abundant trichs? All plant proccesses require energy, that is why there is a limit to what straight darkness can do. By your rational, you could put your 8 week old seedling in a dark closet and run water through the soil and in 9 weeks you get one giant trichcome. Or a ball of resin sitting atop the soil. Or a packed bong. Who needs light? This shits magic.

5000's plants are some of the frostiest I've seen to date. However, I do agree with what research indicates about the 72 hour dark period. I'll have to run two clones next time around, and then test the difference between 72 hours and 7 days.

It really isn't at odds with the UV-B idea. Some THC is broken down during each period of light and then during the next period of darkness what was lost plus a small additional amount is created, so you have a slow but steady increase until harvest.

When given 72-hours of darkness the THC production continues as it would during periods of darkness, but without the daily loss during light cycles. Without a period of light/photosynthesis 72-hours is about as long as plants can continue to carry out what to plants would be normal nighttime functions, then they basically run out of steam and their life cycle ends.
