Hi there, your no-trich problem intrigued me so I searched a bit. A guy posted this on a forum: "I run a 1,000W HID with 6" air ducts. My HID generates a lot of UV-B - which is taken out by the lens. Essentially, the plant is getting no UV-B if it is running with artificial lights indoors with a glass sealed reflector.
It turns out that UVB is responsible for the generation of essential oils (among other things)... which means resins... which contain cannabinols such as THC and CBD.
So run out to your local PetSmart or Amazon and find a UV-B Terrarium light with a rating of 10 (not 5) and get it hung within 20" of your plants. Give it a couple of weeks and you will be shocked at the increase in trichomes.
This will actually work... unlike most of the bloom boosters." Not a specialist myself. Good luck
