Iv'e read quite allot about this and it is something i am going to put in my grow ,
when you think about 5% it sounds allot but it is 5% of say 20% THC = 21%
Everything iv'e read shows it works , and it does not cost allot to add so why not .
Be safe .
In my country, I read that a lot of people run UV neon tubes a few minutes a day for more resin.
They get them at terrarium/aquarium stores (black light for lizards, lol), and there are leds spots too for UV only, or may be night club supplies.
If you live in an urban area, where there is NO NIGHT (light pollution), and if you have grown outdoor in that environment, I would be interested to know your results in terms of high. The same plant grown inside is like, a LOT less powerful than the same one grown outside in those conditions , which was more powerful sooner. It did not have a lot of light per day neither, may be 8 hours max of full sun in July August. It could be the phenotype though, as 2 plants is not enough to make a comparison.
I am tempted to recreate that "no night" atmosphere in a tent
with a few orange leds for PC and decoration, and may be a couple of UV tubes for a few minutes a day.
In fact, does anyone actually grow outdoor in an environment where the night can actually be called a night ? it becomes hard to find nowadays....
