I have read that introducing UVB in and indoor grow produces higher levels of potency in your buds. My question is, when is the best time to introduce UVB and what products would you recommend? I have 4, 2 foot, 17 watt flouro strips and 8 CFL sockets to potentially work with. I am leaning towards picking up 2 of the highest wattage UVB CFL's possible from any one of the local pet stores. Anyone have any other ideas? Any comments are welcome here!

I use 2 foot long reptile uvb during the last half of flowering. No point using it the first half imo since the trichomes and potency happens mostly in the later stages of flowering.

i was planning on picking one of these up an setting it on a 6 hour during flowering, or possibly the whole time. it wouldnt hurt to give it a try, ill have to see when the time comes just like you.

How many do you use? Do you have any comparable information? Have you done a grow without UVB grow and one with and seen any appreciable difference? Has anyone done this besides Young?

Fast forward to 13:00. He discusses UVB. Great video. Definitely going to add 2 of these UVB lights without a doubt.

I have also heard a great deal of theory about UV light improving thc potency, but yet to hear anyone endorse it through actual experience. I would like to hear someone claim it improved the the potency of their grow first hand!

Will prob try it anyway..lol

I am going to be buying 2 of the 26 watt 10.0 UVB lights today. I plan on putting them in at first sign of trichome production. One on the left, the other on the right. If you watch my grow journal in my signature I will be sure to keep everyone updated as things progress.

Yes i do believe it makes a difference. If i were to take a wild estimate, i would say it has the ability to add 3-10 grams a plant if used with a hps. The sun puts out a great amount of uva and uvb rays. Ever wondered why outdoor bud is so much bigger and fatter? Now no man made light has the power to mimic the sun but uvb lights do help cover some of it. Just make sure you turn it off when in the grow room or under it..Too much uvb can cause skin cancer. cheers -young

UVB isn't supposed to make buds bigger. Its supposed to help enhance the process of converting the chemicals (CBD, CBG, CBN, so on and so forth) inside the trichome to THC. This is a theory as to why bud coming from Mexico and Afghanistan have such high THC content. Those specific area's have very high levels of UV radiation. I do not believe there has been any actual scientific studies done to prove any of this but the idea and concept seems very solid and for 30 dollars its a very small investment if it works.
