No, my point was really that if you look where cannabis came from, all areas are quite high uv compared to Cali. Coincidence, hmmmm. Peace GS
I tried to use UVB to improve plants but have never had any improvement I could see or measure via analysis with my GC. I used them both with Sodium and Halides indoors as well as in my greenhouse with sunlight thru glass. The test was a bust, the 5 foot plants in the closest rows to the UVB got burnt, the next row was a little yellow around the leafs, the next few rows not any real negative things to say except it did not increase the THC one bit. The two closer rows had less THC then controls without UVB, and less weight, specially the first row.
GS have you ever grow a crop with UVB as well as controls of the same clone without UVB and had it analyzed to see if the THC totals change? Or the Terpene totals? I have and I could not find any improvement.
If anyone knows of a post that shows analyzed improvement with UVB, I would love to see it, please give me the link.

Cannabis only comes from those areas? And all these years I thought it grew wild all over the globe.
Huh.

G`day Sam
From what I understand UV lamps have a high freq wave .
Thus dissipates a short distance from the source . Would having the lights move to mimic the Sun`s arc make a difference . ie the whole plant gets bathed ?
NO IDEA.
Were you able to measure the energy from the UV lamps at different distances ?
NO.
Also did the plants spend their whole lives exposed to high UV ?
IT WAS A 12 INCH CLONE GROWN TO 5 FOOT AND FLOWERED UNDER UVB.
Your old buddy Rob talked about THC V in areas of high UV exposure around the globe .THC V has had my attention ever since . The best smokes from the tropics, have some thing special, herb grown outside the region rarely have . Can you comment about high altitude Indica plants having THC V ?
THCV IS NOT ACTIVE PSYCHOLOGICALY AND IS IN FACT AN ANTAGONIST OF THE THC AT THE CB1 RECEPTOR.
YES YOU CAN FIND SMALL AMOUNTS OF THCV IN ASIAN AND AFRICAN STRAINS.

@ Green Supreme .
I noticed the difference in UV in Europe compared to Australia this past Summer .
In Oz 15 minutes in the Sun between 10 am and 3 pm will cause skin damage and make your skin turn pink if not acclimatised .
All day in the Sun on the hottest days of the year in Belgium and Sthn France and I hardly got a tan !
Thanks for sharin

But find a special plant, one that can handle light conditions in excess of 70wpsf, a plant that don't burn under the intense heat and lumens beating it. I often find these plants which when they are saturated with light, don't burn, but rather handle it and put out another coat of resin to protect themselves from any unnecessary light damage to their photosynsthate processors, it's a nice trait to have in cannabis. Intern it creates more attraction for pollinators, or indoors more of a chance it will be cloned or liked by the grower. Its genetics (plants seduce growers into keeping them going its magical)
If I am correct RiverRock said they use fresh plants flash frozen to make the water hash, then they used sublimation to remove all moisture from the frozen extracted resin, but anyone can do this I suggested it years ago. The real secret is real low heat to preserve the terpenes, sublimation as well as the fresh plant extracts.
