and as for your plants....[...G: Interestingly, research has shown that cannabinoid precursor (I forget which it is CB?) conversion into THC most likely happens with most efficiency, and hence, highest conversion into THC, between 280-290nm.[1] Even zoo lamp UV-b bulbs do not emit much irradiance in that short of a wavelength (aka nano-meter; which is the "length" of one "wave")...The trick to supplementing UV-b is short increments. In Nature the highest irradiance of UV-b is from about 11am to 3pm, four hours. We should try to emulate that time frame indoors. In all the studies I have read the researchers never used more than four hours per day-length of photoperiod. And most supplied UV-b post-solar noon. I am adding UV-b for two hours starting one hour after solar-noon (after 'midday' of day-length). Supplying more UV-b than four hours can injure plants, less is more in my opinion (to an extent).]...so like i said something to look into...sorry 4 double posting...
