... and luckily hydro costs are pretty insignificant for moon lights, unlike metal halide.

eg. 4 watts x 12 hours/day x 30 days/month x $0.0605/kWh = 9 cents/month.



ok, I admit it, I'm an engineer ...

My only concern with using moonlights 24/7 would be exhausting some of the animals that respond to the light. Terrestrial plants DO require dark nights for optimal growth (hence why they catch the grow ops by looking at power spikes and not just steadily high consumption :D), and I wonder if zooxanthellae have some need for "down time" as well. I've never seen anything written on it either way.
Actually, that might make for a fun experiment when I get playing with LEDs again. I have a small frag of my torch colony nearby.. Might be interesting to leave a blue or UV LED over it all the time and compare its growth to the other colony...

i use a high tech timer on my night light to come on 3 -5 times to stimualte a cloudy night and then some other times it doesnt come on. those timers that y9ou can set for a month of so i think they are in WALMART.

i like them

I'm not so sure that my LEDs have any impack on photosynthesis as my pH drops at night and climbs during the day indicating that photosythesis is still occuring naturally.

Only pennies a month you say. That makes it a plus! I'll have to remember that the next time the wife pays the hydro bill. :biggrin:
