That's about Max for a full moon near the equator twice a year.

Anything less should be well below the trigger level for phytochrome conversion and will not mess with the photoperiodicity.

Got new neighbors next door and their porch light worried me.
As did the hellishly bright seeming streetlights from 2 other directions.
Hadda get a good Luxmeter anyway for my led work so I whipped it out before hassling the new neighbor.

Here's what I found.
The porchlight was 0.1 Lux by the time it reaches my girls.
So, no gotta bug nobody.
The streetlights from 2 other directions max at 0.2 Lux.

3 less things to worry about, yah? :jointsmile:

That's my story and ya'd have to bribe me off it.

That mate was one of the most useful things I've ever read in a forum. Thanks for that, been wondering myself too! :rastasmoke:

PS. Why can't I add rep to someone? :wtf:
