That would be a shitload of UVB, what are you looking to replace all of your lighting with it?
says you can get 3x for 125$, saving you ~$8.34 per bulb. if you get two four lamp fixtures it would be 24X (50-8.34) = 41.66x24= 999.84+fixtures= 1k+600$=1600$Kite High, so if I got my math right, if I installed 2 - four lamp fixtures on each wall my room, it would cost $ 1200 for bulbs alone ($50x24=1200). Then with fixtures at say $100 each, that system would cost $1800? Is that true?
My room is 8x8x8.5 and my thought was to put 2 fixtures on each wall. Would one on each wall be adequate?How big is your room?
Yes, plants do better NOT exposed to UV (I can't speak for cannabis). I found this out in my months of research of covering materials before constructing a large greenhouse. All greenhouse covering materials exclude up to 100% of UV with the exception of glass.Sorry if I missed it, but for a few months now I've been trying to get an answer on UVB photo periods and just get bullshit sarcasm or the "if they can take the sun, they can take artificial light" assumption. It is true outdoor plants are exposed to UV all day... but I know when I go out swimming or whatever, after about 2 hours that's enough sun. So, I really have no idea what a UVB photo period should be.
Quick Google got me this - http://www.gardenguides.com/132133-plants-ultraviolet-light.htmlAnother benefit of UV protected panels refers to your greenhouse and plants. Since the panels have UV protection they also protect plants, crops and flowers from harmful UV rays
The programming is already there so no need to do the long series to put it there as it already is. It is just like any other aspect the stimulus activates the mechanism. They were exposed to uvb for eons. Now selective breeding for plants that are more reactive could do something I suppose just like choosing plants that are shorter will bring down the height of the strain. But remember only the inside grows have denied the uvb presence and that is a small percentage compared to what is happening outdoors. And ALL of them were solely outdoors only 40 years ago.My theory is that UVB will have a much bigger impact used in a multiple generation breeding project than in a single generation growth cycle. In a single generation growth cycle a plant can only do what it's genetics tell it to. I think many generations of high UVB exposure breeding could yield some interesting results ....
