Suburban light pollution

How much light is too much light? I can keep my back yard pretty dark, but it's inevitable that light coming through a bedroom or kitchen window shade or blind, or a back porch light from a neighbor will occur. If a full moon on a clear night doesn't cause problems, are these minor pollutants really likely to have adverse effects?

I’ve had to go up and remove pole lights at my house because they’ve effected the plants outside I look at it like any light during the dark is too much light I know outside is hard to eliminate every light but you do see the differences on the plants in complete darkness and the plants that get polluted with light at dark

I have those small solar walkway lights all over the backyard and have had outdoor plants right next to them. They never seem to mind.

Id shoot that out for my sake. I have motion lights that come on on off all the time headlights hit them etc never had a problem either.

Full moon is .05-.10 lux. That is nothing. I use an app called tent buddy and if that sensor flickers from a 0 to registering 1Lux i know im gonna have a problem. Ive been messing around with lights outdoors for a while. Somewhere between those, .1Lux and 1Lux, is the demarcation line for flowering light pollution.

That sounds crazy . There must be a time factor too? 1 lux is defined as the light on a 1 sq meter flat surface 1 meter away from a single candle. Thats not alot and without doubt my led motion light is brighter than that . You saying im getting lucky mud lol

Yeah bud, something to do with proteins accumulation or something...the buildup of the flowering precursors and then the system flips...i forget the technicals but yeah time involved too i reckon.

That's a relief @mudballs because the exposure where these plants are would be very minimal (probably less than 1 lux) and for never more than a few seconds.

A full moon on a clear night is bright enough to cast a very distinctive shadow and practically bright enough by which to read. The light my plants might accidently get exposed to probably won't ever be that bright and certainly no where near the duration. What about lightning? It can light things up like daytime for a brief moment. But, an evening of thunderstorms might produce 50 to 100 such flashes. That doesn't seem to hurt plants, or does it?

Muds alright man. Might not want to burn that bridge . Not sure what was abrasive but to each his own. Sometimes it takes abrasiveness to create a callous

To answer you its not a factor. He asked, “really” because its nature and man didn’t create weed
