Keep us posted. I was picking up a new light for my lizzard the other day and started looking at the different spectrums they had. I was thinking of doing the same thing but those lights put out quite a bit of heat.

yeah, there has been some debate for quite awhile now, but people are really starting to show proof positive results that UVB makes a difference. I dont know how people feel about linking to other forums, but there is some great info a results shown here:

Well it just makes sense... All opioids and alkaloids are generally produced in response to some sort of stress. THC absorbs UVB really well, therefore it's production, IMO, is directly linked to UVB levels.

I googled "Marijuana UVB" because I wanted to know if anyone other than myself uses this regularly. If anyone come across this...everything you could want to know about UVB use is in a HighTimes articled dated like 1990. My copy is very old but that is when I learned about UVB and it is the reason I think my stuff seems hands down superior to anything else. The article is entitled 'Sheding Light on Grow Lights...UV". Key points are.....
-Philips FS-40 florescent bulbs,
-References an article by Robberecht and Caldwell..."In plant cell environment" (1973)
-UVB converts CBD acid to active THC acids
-Area in Africa which has high UVB intensity in which no CBD was found.
-High corellation between high UVB levels and THC
-Not enough...not effect/ Too much plant dies
-Use only last two weeks of bud production for 2.4 hrs/day during the noon period
-Be carefull ( my first attempt in 1992, I burned myself)
-MH has more UV spectrum (why I don't use HPS, I find that its great for production but not as psycho active) you'll find a lot of learned grower actually don't use HPS for this reason.
- Takes about 3 day for UVB damage to becom visible.

If you're not sure about this, LEAVE IT ALONE!

Use 26w CFL reptile bulbs, 10.0 UVB. The compact florecent lightbulb style, then using $1 store 9ft extention cords, cut off female end and wire a rubberized all weather mogule comes with two wires only so $1 store two prong 9ft cord works best. get as many as bulbs your using, plus a couple cords and use them to wire 3 reptile bulb cords into the female end which has three spots to plug into, I have 4 bulbs taped hanging vertically close to ceiling in each 4 quarters of the room, Its a 3 level 4 side stadium, with 2 ft entrance space with no shelf., reaches optimun 2 ft it says for reptiles, some plants tops are within 6 inches from reptile bulb, no ill effect on close plants, also 1 bulb in lamp in center of room on floor pouring up and into lower plants and undersides of first 2 levels plants. I have not seen so much crystal and almost oozing with resinousness. so its good man. they love it. I have 2 1000w HPS and one 600w MH a foot lower centered between two bulbs above. not this has created like one giant full spectrum sun, more blue lower and center, and more orange light top side of things, overall everything recieves MH and it shows, and the UVB has increased my full spectrum greatly. Ohhh my timer is a aquarium timer, looks like a computer power bar. $40 cost. It can have 7 time cycles per day, so anythinjg with 6-8 time cycles will work. when i first use it's as sson as they switch rooms as only have the uvb in flower room, so the get uvb at 1-2 minute intervals for first week as they root into new 3 gallon pots. then increase a couple mins each week till you have maxed at 12-20mins each time. My cycle is as; lights come on at 6pm, 3hrs pass, 9pm uvb 12mins. 10pm uvb 15mins., 11pm uvb 17 mins 12 NOON highest point of uvb 20 mins, 1 am 17mins uvb, 2am uvb 15mins, 3am uvb 12.. so that is around 2-2& quarter hrs of uvb intyervalled at max time, I don't get to full amount until 5th weekish. slowly increase times, not 5 minute jumps, might hurt them, the bulbs put out mor usable uvb than the sun does at peak NOON time at closest point to the sun on the equator where the shit grows wild and rampant. which is why intervalls, in the middle six hrs of the day, not begining or end three hours. some smart dudes researched this for 3 yrs in 6 different controlled grows and came to this!!!!!!!!!!!!! Cheers happy gowing, and try and teach some fools to use this method, cost me $200 to add to my setup, my 3 week premature sample after i dried it proper, was easily as potent as my finished product last run without uvb, everything else was same setup. and that was some good shit last time, jamacian graspe, and romulanXfucking incredible, same as this time too, and 3 weeks early is almosty dripping with resins
