before he went offline currdogg had just installed some of these extra lights to his grow…I have no knowledge to give up on whether it will make a difference in your setup
Dr. Bruce can explain it better than I can!
But basically UV light is in 3 different parts of the spectrum. UVA is the most beneficial for us and plants both. We HAVE to have UV exposure to be able to process Vitamin D, otherwise our bodies cannot process it and we end up with a deficiency.
We block it with sunscreen.
UVB is more damaging to both us and plants and should be used sparingly. UVC is what they use to kill bacteria and germs - it will kill us and plants given enough exposure. Luckily our planets atmosphere filters the UVC from the sun - one of the many things that make this planet habitable…
UVA can run the whole growth cycle, just like it does in nature. UVB is hundreds of times more powerful per electron than UVA and should really be used for a very limited time on plants. UVB is what iguanas and reptiles get warmth and energy from because they’re built for it. Marijuana is not really able to stand the same abuse from UVB as reptiles.
It basically makes for a stronger, bushier and stouter plant. When a plant goes to flower it speeds up and increases the production of resin, which contains our prize - THC. The presence of UV in the spectrum basically adds a degree of stress to it and as a response it produces MORE resin as a defense mechanism.
Sounds simple, right? 
That’s why the holes that appear in the ozone layers over the poles are so damaging to the planet. They accelerate the rate that the ice melts and speed up destruction of our home.
They do but most of it stays inside the bulb as the glass filters most of it out. If you’re using a sealed HID, like the ones with the glass cover in addition to the glass in the bulb itself practically none gets out.
Same reason you could work in a greenhouse for twice the amount of time you could work in the direct sunlight yet you’d only get half the tan as if you were outside. The glass filters the bulk of it out.
More so with greenhouse glass as it’s treated to increase the filtering.
UVA - good all day.
UVB - small doses for best results.
UVC - we’re all dead!
Have you heard from him yet? I’m worried about him, @Highwayman420 and @Hellraiser
Thanks for the info, I was to lazy to actually research 
Is @CurrDogg420 in a legal state? Last year, didn’t the cops walk in and remove his plants? I hope they didn’t swing round to check up on him and bust him 
I don’t know. I just know he’s been missing. I had no idea they hit him up before. Oh my.
Currdogg is in a legal area and he has medical grow license for up to 12 plants I think…he is legal …I do remember last year them comming buy after his wife past away…I don’t think he had his license then
Oh, I love your babies. I’m so sorry about Otis. I lost my 2nd bully at just 18 months to lymphoma. It about killed me too.
Here’s a thread I started after Otis passed, thought I’d share it if you haven’t came across it yet 
It’s such a shame we live in a country where people are still scared of a little ol’ plant!
Yeah, found his old topic on old forum…“Starting over again”.
Shawn, where are you? To go from posting several times a day to nothing for over a week…hope you’re ok buddy!
Cool. I’ll check it out this evening.
didn’t know his name was Shawn…
He signed that post…
He has a mother a 2 sisters right there by him if I remember right…they have medical MJ cards and he is their designated grower and that is how he can have several plants
