Actually, I tried it in a double blind 3 years ago.

When I set up my G.R. I split it into 2 sections and started with all conditions as equal as I could make them except for one variable at a time.
I found no merit in adding UVb.
That does not mean that there is no merit to be had,
Just not enough for me to detect.

While I have used it for quite awhile, I have never really been comfortable about recomending it. It probably falls into the same catergory as CO2 use, when eveything else is dialed in it, then you try it.

Thanks Old Mac an important point well made.
I'm almost dialed in with the lighting.
Added the CO2 because I had a surplus from making wine and da Weeze don't waste nothin'. (Too cheap ya know.)

It is my opinion uvb can make a difference. It will be pretty easy to test if it will make a difference to you. Do a grow with and without, back to back, same strain, same conditions.

Or, mo' betta, side by side.

1)UVB will not pass thru walls, or even cardboard and is greatly diminished just passing thru glass. It will be safe in your box as long as you can't see it.
2)I would start at 2hrs/day in middle of light period "high noon" and see if you get an improvement. I don't think I'd use it for more then 4hrs/day, like Weezard said it ain't good for plants either (in large amounts).

And hey, isn't marijuana man believeable, he's like a true profesor in his lectures. Plus he uses some common sense. Also, his take on THC claims...gotta luv it.

Nice way to put it, believable, I like that.
Damning with faint praise. I like that a lot.

Stoner assumption are quite amusing but science, they ain't.

Neither are my anecdotes and observations.

My THC levels in meds grown without a trace of UV do not prove that UV is worthless, just that it is not neccessary for potent bud, yah?

I thought that 'Shake was asking if being in the tent with the UVb for ~5 hours was safe.
Had me worried for his safety or I would have kept my nose out.
Thanks for leaving a more rational reply. You do have a way with words ya ol' fart.

Aloha nui

Weezard Reviewed by Weezard on . uvb safety what's good everyone? i've got a few questions about uvb safety. i picked up a exo terra brand Repti Glo 10.0 uv bulb. i've been reading the uvb log (you know the really crazy out of control one?) and think i have a handle on the safety precautions. 1. don't look at it/wear sunglasses 2. don't expose your skin to it is there anything i'm missing? also, my grow box is made from corrugated, some thick double wall stuff. i have it lined with aluminized auto sunshades. it is Rating: 5
