great question and great replies!

i think (emphasis on "think") that maybe plants "adjust" to certain things ... and one of those things is the amount of extraneous light during the dark period ... though after a certain amount of lumens (or is that lux?) they may hermie or not even flower.

i have had lots of hermies .. all from bag seed except one case of heat-stressed hermaphroditism ... and i regularly use flash to take pictures during the "lights out" period.

...100% darkness isn't as much about the plants as it is about being dummy proof.


Imagine all the threads over the years of people asking, wondering and tinkering about with the minimum total lux that'd engage photo cells into activity.

It does, and I have seen it for myself.

Where I used to work there is a lilac bush growing directly under a security hps light which burns all night, every night. The bush never wants to drop all its leaves in the fall, gets random blooms on it spring thru early fall (should only be mid-spring), and is generally a sickly plant. Other lilacs growing 20+feet away have none of those problems.
That's only one example, I could easily find more.

Observation of the natural world around me is one of my hobbies. Totally free and very educational. So many walk around with blinders on, I find that sad.

Ok, well what about indoors, not outdoors? Thats how im growing, indoors. I have some morning light getting in through the vents in my Air Conditioning unit. If its an hour or so, is this going to affect my plants negatively?

What you need to do is attach some Ducting Between your vent and were ever your venting the air to or from, Make sure you have atleast 1 bend as light canot travel arround corners.
