I don't think so, but my boobs do kinda hurt... The hand is getting better though. Would likely help if I quit bumping it on everything. Amber (my wife) is still mad I wouldn't go get it casted.

Was wondering...(rut ro)
Are there wavelengths from our other lighting sources (HID, CFL, T5's, LED's...) that can cancel-out, dilute or distort UV light before it hits the plants? I know I read something along those lines not too long ago, but I guess age has it's drawbacks. I can't remember where. A photography forum, perhaps...?

Regarding using filters...are there any filters that would let the UVB through it unscathed, and which wavelengths would be affected by the mixing of colors from the filter(s)? I wonder if it would inhibit photosynthesis, change biological processes (wound repair, internode stretch, nutrient uptake...)

I hadn't really thought of it before, but has anyone tried infra-red? (just curious)
