Hey Skunk 
Did you ever pick up a uvB radiation meter to measure?
I'm thinking of vegging my outdoors under uv. Any ideas?

hey YGF, I was wondering where you'd got to. Was contemplating sending you an email just to check on things.Hey Skunk

No, I went and bought a lux meter, which is ok but the novelty wears off quite quickly. I really need one of those (UVB meters), but it's going to be a couple of months before I can spend freely again... well not exactly freely, but you know what I mean.
Do you mean UV combo with fluoro or mh? Or just UV on its own?

WOWOWOWWW!!!! those are some great systems....
i like those spinners.... i'd get a dual spinner with an hps and an mh bulb and those eballast with the spinner!!!!! wow!!!!!!!
although that would cost 1,000 dollars, but it would be very much worth it!!!

This thread really make you think. All of this talk about UVB light really makes sense and I don't know why this information has never been part of indoor growing guides. I think the experiments that people are doing here are going to show some amazing results.
Does anyone have any good suggestions on what kind of source offers the best range of UVB?
Also I found an interesting article about this topic that I think most of you will enjoy.

I am not exactly sure, it is a Philips Cleo Home Solarium unit 4x15watt tubes, I would need SKH with his trick meter to be certain.
I shall use a BlakRay lamp as things progress that is calibrated to 320nm. I am not sure how useful that will be, as it does not have great penetration.
The suntan array is doing fine, I want to see the trichome distribution before coming to any conclusion though.

Well this is a peek inside the tent. All plants clones, all fed from the same reservoir. The only difference is that the taller, more advanced plants have been getting a regular suntan, starting at one hour a day in veg, going up to two hours at the start of flowering and 4 hours a day when nutrients were changed for the second stage of flower (12 days ago).

Hey there, Just thought i would point you guys to this site i came acorss. Lots of UVB specs of lights. I read that the Nec Black Light T10 20w rates high in the Snakes, Pythons, Lizards world. Lots of pet owners seem to speak highly of them. Quite cheap and considerable UVB output. Also in the lists below are other light types (CFL's, fluros, MH's etc...) Hope this is helpful. Project UVB RDU - UV Lighting Information - SA Test Other tid bit... RDU - UV Lighting Information Peace. P.S. this seems to be formatting weird...
