Do I have to give my plants 24 hrs of darkness befor harvest?

You do not have to change its light cycle. Experiment with the others to see how they respond. Report back. Can you pull the one plant out (bucket and all) and move it some place where you can give it total darkness? I suppose you could also cover it with a good 6mil black contractor's trash bag if you want.

it would be more like 48 to 72 hours of darkeness, the theory, which has been proven true in SOME strains, is that thc% can be increased because the plant produces thc in anticipation of the sun rising, when it doesn't, more thc is produced. You would never see enough of a difference to know if it workes or not.

It does work. I took 2 plants both of the same strain. I let one sit for only 12 hrs in the dark b4 chop. And the other one sat in the dark for more than 24 hrs. And the frosties were significantly different. The one 5hat stayed in the dark looked like it had been snowed on and had way more trics then the other.

Thanks for the quick responses guys.

I cant cover or move the plant as i trained all the plants and they're all interwoven into one another. The only way i can move it out is if i chop it down, and i cant cover it as it will also block the light to the other plants.

Does watering the plant with really cold water produce the same results as leaving it in total darkness for 36 hrs? Or is it for something completely different?

All help is appreciated,

Thanks

i almost always hear that it "appears to have helped"

i have yet to try it myself

most people do 48 hours though

i read some where about drowning the roots for 24 hrs in darkness before harvest really helps with thc production .. i haven't tried it,, but on this yin i will so fingers crossed

I haven't ever tried it, would like to see a side by side comparison, but who can test the potency accurately? Mine are in the ground, so they will get around 11 hrs darkness when I harvest them...

When you say drowning do you mean with water? If you just mean to go 24 hours of darkness that's fine, that actually does increases resin production. The plant thinks the end is near so in a last ditch effort to get insects to pollinate it it increases to amount of thc to "lure" them to the plant.

Potency is testing with a microscope and is based on the number of thc "heads" I think. More trichomes=more potent
