When to pull supplemental lighting?

[dono]

Or should I have already done this?

Been having a CFL on 645pm-1045pm. Safe to pull the plug now?

Clone starts. Been vegging couple months.

Where are you? I'm at lat. 42 and the days aren't getting longer. I'm just waiting because I want an extra week veg and don't have dirt until this week.

I think we both should be good to go any time now. If your on a long days schedule they might bloom immediately. Mine are going from 24 hrs and will bloom right away and stay until ready.

Guess I should tone it back an hour instead like 945 instead of 1045?

I would just hate to pull it only to have it start flowering, then get confused into reveg and back to flower. Which will probably stunt the fuck out of it.

So why not just keep it going until you're ready to flower? You should have transitioned them to match the day hours of around the beginning of June and pulled the supplemental lighting then as we approached the solstice. (Although some say you don't need to change their hours as long as you wait til the days are long like beginning of June). Now the days are getting shorter. They still shouldn't flower since the days are still long but I don't know for sure since maybe they pick up on the days decreasing. If it were me I'd keep lights going until August because otherwise I'd just be worrying.

I can't believe it's already the end of June coming up.

At my latitude 42N outdoor plants will have naturally started flowering about now, since daylight is decreasing the plant will not get cues to revert back to a vegative state. A long/late blooming sativa might be different, I am growing indica dominant strains.

Please someone correct me if I'm wrong, I'm still holding them off with 80w flouro.

If you are very concerned then one way is to estimate your first fall frost, subtract expected flowering time, this tells you the amount of time you have.....unless you think you can flower early and avoid the fall conditions.

What I would do is continue sup until 10-12 weeks before first frost. Just kick on the lights one hour before and after sunrise/set. I don't see why you have them on for so long....

Anyhoo hope this helps I've been reading a lot because I'm winging it and hoping for the best of course.

And yeah a reveg outdoor is pretty much game over. So that would suck bad.
