I may have an explaination of what you are seeing.

The resin glands start clear and the plant makes new ones at a steady rate
The clear ones are hardly affected by the UVb.
Goes right through them.

As the plants mature, the first blush begins to ripen and cloud-up.
A cloudy cap IS affected by UVb in direct proportion to it's opacity.
A cloudy cap can darken, then shrivel, then fall off, in a single 8 hour exposure to UV.!

It's a continuous process.
Timing outdoor harvest can be tricky depending on lattitude and cloud cover.
You want to try to catch the last big burst of coudy trichs before they fry.

It's an ill wind, that gathers no moss...

So, I deprive my girls of UV during veg. and flower.

The buds continue to produce resin glands and the caps ripen and cloud without shrivel or drop offs.

They really pile up under LEDs.

Almost every trich is still capped too!

Then, I hit them with measured amounts of UVb and "tan" them to a turn.
1 hour exposure is noticeable in it's effect.

And 4 hours, near the equator, makes for some couchlock-tanglefoot.

I have no lab-rats but the wife and I.

So, testing has been a problem.:stoned:
One hit, and we lose the pipe.

Should we find it and dare a second hit we lose track of what we were supposed to be testing for.:stoned::stoned::stoned:
It's a major cause of dangling participles.:jointsmile:
And don't get me started on what it's done to my chess game.

I may be wrong, but so far, it's not so much if, you use UVb as it is when, and for how long you use it.

Hermie's doing a test on fresh cut LED grown buds to see if they need to be alive for the toasting.

I'm betting that uniform exposure to UV will be more difficult, but that exposure WILL let you tailor the character of the "side effects".
Time and curing will tell.

Does this get ya thinkin?

I love the Canna forums. Look at this post, what a great and knowledgeable community we've got here.

Weezard, again thank you for sharing your advanced knowledge of growing with me. The clear trichomes not being effected... wow, you sure gave me something to chew on (thank you thank you thank you!)

I've been running my UVB through out the flowering session, believing that b/c of my use of a Super HPS w/tempered glass reflector, I wouldn't be getting any of that lower frequency which would lead to lack of potency & ripening. But you're telling me the trichomes will cloud on their own, yes? And if they do so when the UVB is on them, they will amber & degrade rapidly, I take it.

The UVB is at a distance of no less than 24" away from the plants and are on 5 hours a day. Since I am growing sativa dominant strains at the moment - I think I will shut my UVB for now & only turn it on at the last or second to last day for one hour if I think they need ripening up. So UVB does not cloud the trichomes, they cloud as they mature... They will cloud on their own, am I correct in my reading of your post?

May I ask how far away you place your UVB lights when you shine them on your plants? My UVB lights are T8's, 3 foot long, 36 Watts each & there are 4 of them. I imagine UVB, being at the lower end of the spectrum does not dissipate the way red light does & is able to penetrate from greater distances.

I do want these plant to have a more head high with only the C99, Blueberry cross having much body in it, so my need for amber is not the same as that of a person growing indicas for pain management, for example, there more UVB exposure might be required.

Just 2 things - wow those LEDs produce amazing trichomes, no wonder everyone raves about the potency of LED grown bud. 2- I'm amazed at how little amber causes a couchlock stone! Thanks for the heads up, as I'd have ruined my plant's high going for a 50/50 mix of on the sativa-indica crosses!

I'm off to hermie's thread - thanks!
