Hey Dogznova,

I look forward to someone releasing a chart or something listing the various "speeds of light" or time factors and there effect on plant growth at various stages of the plant's development. I have a hard time wrapping my brain around this, I would love to know why far red is fast yet red is so slow.

Hello Bubbleblower,

Interesting patent you posted, UVc has long been used for both air and water filtering for the very purpose of killing pathogens. The first line of defense in not having crop loss in a greenhouse (or an indoor growing area) is good hygiene. That is running as sterile environment as possible, but difficult when venting a greenhouse to keep spores and such out.

The possiblity that UVb may be the cause of more fragrence in flowers growing may account for the fact that growing with most LEDs causes much less smell problems then when growing under HPS.

Your use of UVb seems well thought out, just keep in mind your safety when using it.:thumbsup:
