Keep them on 12/12. What a lot of people do is during the last 2-3 days they have the lights off 24 hours a day

I never heard of 18/6 for the last 2 weeks.

I do 3 days of compleat darkness before I harvest, that sends the plant into panic mode thinking winter is here and increases resin production to protect the non-existent seeds from the upcoming cold weather.

what is your exact light timing now? i have been messing with timing since i heard it can make a huge difference, i am running 11:15/12:45 right now but never heard of 6/18 where did u do the reading on that?

read it in post about ww and when to harvest

thanks for reply

I run a 24/0 cycle for vegetative phase, then a 13/11 cycle for the flowering cycle, and then 3 days of darkness just before chopping down. (Note: 13/11 = hours on/hours off). The length of these cycles varies, I let the plant tell me when it is ready for the change. But average is 5 to 6 weeks of veg, and then 10 to 11 weeks of flower, Also I go by the color of the trichs to determine when to harvest not time.

will 3days of lights off hurt the other 4 plants they have about 3wks till they are ready
I have all in same space

I run 24/7 veg 5wks then 7pm to 7am 12/12 for flower just want to know if 3days of darkness will hurt the other plants that are still flowering they have 3wks to go

Yes it will!!!!

I take mine out of the grow space and place them in a closet and shut the door. DO you have a place that is dark like a closet, basement or something?
