<span class="link_user">@GuerillaPL86</span>, Yeah CLW also claims UVB is required and cite a source that “proved this” by growing in a greenhouse. They also claim UVA does nothing so I take whatever they say with a grain of salt. They also say that UVB can be used all the time and that’s just not true with Cannabis - it’s too destructive in high doses.) UVA is far, far more prevalent in the atmosphere.
Think about it: why would UV only increase THC when we know it increases the number of trichomes? It’s just a stress response. (UVB works btw but it’s more destructive to both the plant and people under it and you want to limit the exposure to a few hours a day at the most.)
