Are there no good UVB led options?

Not yet. Unless you're willing to spend $100's per. There's close UVA NM LED's, but not the exact UVB range.

Yeah I saw the crazy priced ones. That explains all the fluorescents still being used. Thanks.

Dropped off the sample today at the lab,potency test will be done next week and the terpenes the week after. Would have preferred a side by side run but it is what it is.

is this outside of the plant to plant, or even bud to bud, variance in potency?

Everything I've seen on the subject is a 3% to 5% increase in potency with HPS when adding UVB. Not sure if it translates to a fuller spectrum like high end COBs. Things that are the same are the lab,GG#4 clone only cut,3x3 tent scrog,same 3070 light fixture,same pot,same feed,same soil and 730 nm flower initiator. Differences are the original test was last year and this years test plant had UV.

This is by no means scientific but total Cannabinoids are up 3.1%,waiting on the terpene profile.

Do you think running the UV lights for a longer period of time would translate into higher increases? If I had a lab nearby I'd do a run with and without the UV and the COB's to be sure ............

I always use Uv from planting right through, you notice the difference against one that hasn't had the same amount as in adding Uv after sprouting, grown a couple as comparison's and it changed me to Uv 24/7...but thats me
try it for a week and see...take pic's to compare

I just started running it in my flower tent for the light cycle and have a bulb en route for the veg tent thanks. You run COB's for your main lighting?

UVB bridgeluxs???
great data keep em coming.
One little problem is that 3.1% total cannabinoid difference is easily within the standard deviation of the labs.
