That's exactly what I was thinking. I'm going to turn my flood lights off when they start flowering, but we have quite a bit of time until that. Thanks Speedy!!
It's definitely true that plants which consistently get light at night will revert back to the vegetative stage (re-veg). They can also sometimes grow male flowers (herm) from interrupted or irregular night periods. However, I'm not sure anyone knows exactly how much light it takes. It probably depends at least a little on the strain to some extent. The "color" of the light also has an effect, as blue and red light may disturb the night period, but green light does not.
But a safe rule of thumb is your "night" should be less bright than what the plant would naturally get from a full moon. The night under a full moon gives you up to about 1 lux worth of light. Just for reference, 1 lux is equal to the illumination of a surface one meter (3.3 feet) away from a single candle. So you want it to be less bright than that where your plants are!
Oh I see. Yeah I just went back and read the OP so maybe I just read the question wrong. Still a bit confused about his flowering program.
The light cycle interruptions causing hermies issue is a huge discussion because lots of people have had different experiences.
Indoors I've always found a direct link between light leaks and hermies.
Outdoors sometimes people report hermies from irregular light interruptions like bright lights randomly coming in at night. But most regular predictable light sources don't seem to cause problems. Depends a lot on the strain.
Outdoors I'd just let it do its thing.Unless you're heading into veg conditions because of long daylight hours.
just seeing that answer now. I somehow got the idea in my head that you wanted to force flower in early summer, and ran with it, lol.
I guess it's because of the tarp reference. The dreaded tarp. Flashback to my friends spending the entire summer bitching about their tarp.
So I think I'm going to end up using a tarp to some capacity in order to keep my neighbors lights and my OWN flood lights from confusing my plants. Thanks for the info
