Well I've got to say UV is a very big component to improving resin production. That's why I go with things like the
BestVA 4000 over quantum setups like the spider farmers.
Details:
Rated power: 4000W
Actual Power: 690W
Item Size: 30.5"*14.6"*5.7"
Item Weight: 19.8lbs
Full Spectrum:
280nm ~ 315nm -- Influence on morphological and physiological processes is minimal
315nm ~ 420nm -- Chlorophyll absorbs less impact photoperiod effect, prevent stem elongation
420nm ~ 500nm (blue) -- Chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis
500nm ~ 620nm -- Dye absorption rate is not high
620nm ~ 750nm (red) -- Chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect
750nm ~ 1000nm -- Absorption rate, stimulate cell elongation, impact of flowering and seed germination
>1000nm -- Converted into calorie
Even the 3000's and 2000's, 1000's series are excellent lights, just smaller. I've also got (2x) of the 3000's. The 4000's beat my commercial double ended HPS/MH lamps... (with half the power), and it's not even close, they OUTPERFORM them, hands down. With virtually a fraction of the heat produced.
That said, I think Bat Guano is about the most simple method of really accelerating good oil and resin production. Overdrive is also a really stand out product, (but a bit more pricey), Cha Ching by foxfarms is an affordable alternative also, especially if your looking for a flowering "program" formula that can be tailored and evolved over the flowering cycle. (Open Sesame, Beasty boys, Cha Ching), but they all cost $$$
Bat Guano is the cheapest, and most effective IMHO.
The other 300 lb gorilla is using a dehumidifier, get one of those for your flowering cycles, and you'll see huge improvements, both in resin production, and overall quality of
terpenes, flavonoids and massive trichomes. Cool dry weather (with plenty of airflow) is what really drives resin production. (in a balanced ph environment, with plenty of sunlight and appropriate nutrients).
I don't use dehumid during the veg cycle, or even during early flower, but once it get's mid and late flower, it's mandatory for me, because I don't top my plants, and I get donkey dick sized buds that can easily become moldy. Dehumid (or AC with Dehumid) is a HUGE gain... and the "dry/cool" makes resin explode.
Darkness helps during the harvest. I see nothing wrong with leaving them in the dark for 48 hours, if you feel that will help. The pro I've been friends with for decades swears this helps, leaving the plants "in pots' and letting them dry stalk in pot (he never removes them) Just shuts off the lights, drys out the room, and lets them cure right on the stem in dirt for 10 or 12 days... The theory is, that resin production continues after the plant dies and the stem continues to feed the plant a bit, even after it's dead, gaining the remaining product stored in the roots....
