Limit light in greenhouse to induce flowering

Jesperadostarted grow question a year ago

Will the some limitation of light in the morning and evening help my PP plants going into their flowering phase? We are currently having days lasting well over 17 hours in my region, so they need some help. I can't afford a blackout tarp, so I was wondering if this could work?

How tall will they grow to be?How tall will these outdoor untrained, soil based photoperiod plants grow to be (best rough guess)? I believe they're a sativa-dominant Sour strain (either Ultra Sour or S.A.G.E and Sour bag-seed). Currently over 1 meter tall from soil at 60 days old in 7 Gallon pot.

Help with issues ID I have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

Is she within a week or two? Goal is head buzz, energy, etc., last thing I need is sedation. :)Ready to harvest in a week or two? My eyes don't see well, I had to cut a small flower from near but not at the top. The strain is Trainwreck (Arcada Cut) from Twenty20. I'm getting anxious to pop a Green Crack Auto. No diary due to laziness, ill health, lack of motivation. 😀

Is it safe to tweak your light cycle times when you flip?I'm getting ready to flip and was hoping to adjust the cycle time when I do. My light is currently on from midnight to 6pm, but would like to switch to 9am-9pm or 11am-11pm to better align with my schedule. Am I safe to adjust or should I keep it at 12am-12pm when I flip? Thanks!
