I would reccomend making the cahnge all at once.

Otherwise, the plant will sese the days are getting longer each time you do this.

Make the switch all at once and do it pronto.

One day wont change her chemistry plant wide...

But several days will.

Thaks my thrity two cents
HARDDON Reviewed by HARDDON on . Adjusting darkness times I've been flowering a plant for about a week now, the dark peiod is from 6pm to 6am but in about 3 weeks i plan to start flowering another two plants but i'd prefer them all to be dark from 8pm to 8am. so basically i'm just wondering if i could change the dark times and what effects it would have on my first plant. I'm guessin just givin her an extra 2 hours one day wouldn't be too nice but could i say up it by 5min each day over the next 24 days? what effect would this have? Thanks for Rating: 5
