Am I okay on leaving my plants on 20/4 lights until a week before moving outdoors? Then I can match the actual daylight hours and adjust my artificial lights timer for those times? I changed over from 18/6 to 20/4 a week ago. Should I start introducing some hours to sunlight now when it’s about 65F+ (I did this when they were seedlings)? Thanks for the heads up, I plan on moving them outdoors the first or second week of May. I’ll have a greenhouse ready also for windbreaks and any potential bad weather! Thanks so much. I’ve already topped and fimmed, there looking great, trying a few methods with each plant.

No, to go from 4 hours darkness to 14 will flip them, then after a week or two, they start revegging because the daylight gets longer til june 21. You could use light deprivation to keep them in flower, put them in a dark place at night until say 8 or 9 am. My experience and opinion.

thanks, I was planning on leaving them indoors until mid May and at the latest have them out full time by June 1st as there will be more than 14 hours of sun. Also in the meantime I’m going to change my light schedule to like 16/8 on May 1st. Give them a month to get used the time. Would that be fine so they don’t reveg in your opinion?

Its hard to say, i’m running 15/9. I read on here that you can bring the light period down 15 minutes/week to prevent flowering. What i know from experience is if they go from 6 hours darkness to 11 or 12 hours some will flip then reveg.
