Never knew that but yea you flower cannabis with a 12/12 light cycle. I only grow vegetables and peppers these days but what other plants use 12/12 if you don't mind me asking.
I was being sarcastic about your "the only reason to run 12/12 is for flowering cannabis".
It is statements like that that create a false perspective in the outsiders eye... "oh.. You grow hydroponics! I got ya *wink*"
If you read my post to the op above about photoperiodism, you would see that I did indeed group cannabis in to the short-day group of angiosperms.
We would love to hear about other different plants and their light cycle.
I have been playing with growing Arabidopsis thaliana. It is a small flower that is native in Europe and parts of Asia.
It has a very short life cycle and requires for 12/12 or less and needs vernalization to produce flowers.
Why you ask? Why not!?
Done deal! just placed the order for a 1000w dimmable HPS system with the 48" sunsoaker reflector. I would have went with 2- 600w units but just couldnt justify the extra cost. now.
Will update when it arrives and I get it up and running.
Congratulations man!
Just remember. You purchased a high powered space heater. You will need to ventilate your area if you plan on growing hydroponically.
