Using uv light to increase resin production

I also have a uvb meter (Solarmeter 6.2) and use a Reptisun 10.0 cfl. Did you measure the 150 uw on your plants and not get the results? The uvb drops off really fast I guess you know. Goes from close to a 1000 at a inch to around 100 or less at a foot. So it is hard to use the uvb really.

I have to have the closest buds at 500 or more so I can get the distant ones to have anything.
not with the correct lamps it is easy....these are the only AFFORDABLE lamps that supply adequate levels without heat problems...all those other reptile uv lamps are useless for our goals...as you stated their output goes down too quickly or they run too hot....see NO REPTILES need 400uw.cm2...and from my testings yield suffers if you go over 500 and no added potency or more accurately ratio manipulation

the arcadias supply adequate levels at 8-12 inches and the mh at 3-4 foot


also they get this supplementation throughout their life, from sprout to harvest

I run the t5s on the sides and the mh's on top...and for the entire lighting cycle...and there is A PROFOUND DIFFERENCE in the lab tests and even moreso upon consumption

BITD they used to make vertical and horizontal bulbs if you turned a vertical bulb horizontal it would kick out hard UVB. Worked awesome but then they stopped making them...

Kite High, I am growing in a 2x2x5' tent so the cfl hung vertically in center of grow, is already a tight fit with 5 other lights in there already. Will not be able to use your lights in my tent.

The levels of uvb are 150 or so at the farthest from the light, so that should just barely do it.

I guess you read from Phaeton and his uvb experiences. He gave the 500 uw upper limit and the 150 minimum if I remember right.

If you have the thc levels and cannabinoid ratios and terpenes too if that is possible, I would be interested to know what happened with them. I am guessing thc increased and cbd lessened.

Was the duration of the high lengthened. Was the high more sedating or trippy with the uvb as well as just heavier? Phaeton mentioned the indica put him to sleep after the uvb was used.

Apologies. IME above 400 reduced yield for no more enhancement. Most profound lab test result was 10% increase in thc and 7% increase in thcv With a minuscule reduction of less than 3% cbd. No presence of cbn. This was in a sari a Dom. Indicate to a much less about 1/3 1/2 of the same occurrence but lil thcv. It makes for a creeper high that though you feel it initially it continues to climb higher even after intake has ceased. Very very trippy and quite euphoric. Hope it helps. Believe it or not I feel and seem to think that phaeton had too much light in total And this altered his results a bit from what I see.

sorry but can't comment on the indies as they make me sleep anyways and I do not care for them much at all except for sleep aid and even then not so much.
