Love the experimentation... keep it up! I'm sure UV is part of the indoor/outdoor difference.

mr.botwin you are rather informative. i know its mukki's thread but i must say Thanks for the info.

Yes, Andy, thank you. I was thinking of suspending the UV light on the right side of the canopy. There is a support pole I can suspend it from. I was thinking of going around 6 inches from the screen height but tilted at 45 degrees so the UV is angled towards the middle. It should afford me a bit of a spectrum of distances that equate to UV dosage intensity. I'll probably start off at a low dose; now thinking 30 minutes 2x a day and then work it up from there.
A good analogy could be weight training muscle tissue. The workout stresses and even tears the muscle tissue, but it repaired stronger to withstand the increased stress it has been forced to endure. I had a few breaks of stems doing the ScrOG and the areas above the breaks are doing very well.

shitty about the bugs, hopefully this UV will help, that is what your using it for correct?

Looking fantastic! buds seem to be filling out very nicely.

No, UV just does not penetrate very far so it would be ineffective for that. I just had re-stumbled on some article about UV and the possible natural uses of trichomes in cannabis. Some very interesting stuff and is an area where still there isn't real tried and true methods developed by the community on how to best use these. I will have it suspended on one side of the grow and will be tilted 45 degrees so the UV light can spread across the canopy. Its intensity will fall off of course and I am hoping to see a shift in how the buds respond to the varying levels of UV light. Can individual buds on the same plant respond on a localized way where exposed sections become more densely covered in trichomes or will the whole plant respond to it? My method won't be very scientific; but I thought it still would be worth it anecdotally.
Don't they use UV in hospitals for some sort of germ or bacteria control?
Would that provide any positive or negative side effects? Perhaps throwing of the benificial bacteria growth, perhaps any other number of unknown issue?

Thank you very much for the article Andy. My tube isn't in this article but the intensity doubling with a reflector and tube added coupled with the info found on my particular tube below, I will at least have a guess as to where I want to put it. I hadn't thought too much about the what intensity I wanted but numbers between 170 and 250 microwatts per square centimeter are what naturally occur in the classic marijuana growing regions of the world. (EDIT: Not sure on these numbers now ... thanks go to Andy's link)
Here is the link to the specs of my tube.

sup munki stop in to take a look,seems like you are doing well gj bro

UV light has many applications and covers a fairly wide spectrum. We are looking for a pretty tight useful range in UVB for THC realization in the trichomes. They aren't high energy X-ray or gamma rays though and remember outdoor crops will see much more UV than I will be able to provide. My experiment should present a radiation intensity gradient due to the light bing positioned at 45 degrees. I'll get a pic of it once installed.

Thanks for stopping by; I know you have been busy. Just been tinkering away, hoping the thrips don't get too bad and adding a UV component to the spectrum on one side as an experiment.

I re-potted my clones today. Did you y'all know that cannabis seems to like Fox Farm Ocean Forest soil? 
The roots had already reached to the bottom of the pot. The re-potting was kind of rough so if they don't show too much stress from that, I'll have to credit the FFOF with the vitamin B-1 fert added to the water.

FFOF is pretty good, i have heard that its even better if you cut it 2:1 with light warrior.

I had bought it before I even started growing. I don't have a proper veg room, so it was easiest to pop the clones into it to see what would happen. So far, so good. They are under 2 27 watt 5500K CFL's right now. I just didn't want to give up on the genetics of my plants just yet. Now the balancing act of keeping the little ones growing but not too fast as I have to finish up the ScrOG grow first. I'll flower them out this time in soil and compare the two grows. I'm open to suggestions on how to do a dirt grow. I think I can get the pH handled but what about pot size for flowering? Should the buckets drain and into what, a big tray? The pot size right now are approximately 1/2 gallon.
I don't want to use my GH flora nutes this time. I would like to stick to "anal nectars" and such this go around. I can't afford expensive nutes, so I will need to make my own concoction from various ingredients. So, any cool links, sites, or threads that discuss formulating natural fertilizers?

Depending on how big you want the plant reflects the pot size needed. If your planning on going past 2 ft in height then get a 3 gallon pot. Personally I put my plants into the bathtub when I water, then place them back in the grow box. Even still I have water trays, they're only like 50 cents and keep me from messing up the floor. If you can't move your plants then you can use a turkey baster to suck the excess water, or a wet/dry vacuum if you have one.
Wow, is that old (cannastats) site on angelfire still up? Makes me feel old, I was playing in ADPC newsgroup when the original posts were... posted. Was it really 12 years ago? Feels like... Yeah, longer ago than last week lmao.
Sorry to hear about your pests. I see anyone mention little webs and I cringe and get this nightmare image of 10,000 red spider mites swinging Tarzan-like from "tree" to "tree" via the webs.
Can call the nearest hydro shop and tell them to send you some hungry predator insects. Or wander into my backyard and pick up a preying mantis or two - or a hundred lol - I thought those things were supposed to be rare but I see countless (trust me, I tried to count 'em... they wouldn't hold still!) ones every time I mow. Those things will eat anything that they can rip to pieces (which is pretty much anything but another mantis - and if you've ever seen a couple fight you'll know that that's a possibility too lol).
I remember that aphid wasps would eat both the adults and at least one stage of the immature insects.
Oh, and adult thrips have wings. Sound like your critters?
Yellow sticky tape... Sorry, Tead, I laughed when I read your post. You... did know that they still worked if you taped the bottoms to something so they didn't swing in the breeze and stick to stuff, right? Then you just have to remember not to try using the adhesive as hair gel. lmao (Been there - had about two dozen hung up, stuck my head into one, jerked to get away, stuck to four or five more, started getting irate, the more I'd try to dodge, the more that were waiting in ambush to attack me; the poor plants/lights/reservoirs/screens took a beating that day from my swatting and flailing. Yep, they work on garden pests of ALL sizes - put some down low if you've got nosy cats!)
UV lights - 50 micro-watts of UVB? Wow, I always figured that the old 400-watt MH that I used for vegging and sometimes as a supplement in flower through out WAY more UVB than that. I could be wrong, of course, but... I'd walk in when it was running and within a minute or so my eyeglasses would be tinted black. If you or someone that you know has auto-tinting prescription glasses, put them four or so feet from that bulb for a minute and see if they tint like they do outside at noon. Think it's the UVB that causes them to tint. Oh yeah, and don't stare at the pretty bulb lol - a lot of eye damage is permanent. Trust me. Legally blind (uncorrected) in one eye now. Kind of sucks when I put the glasses down and don't remember where - I can't see the darn things!
I'm wobbling and listing about 30degrees, time to slide on out.

Your post made me laugh TS. Yeah CannaStats is there and I reference it often.
Got some new pics. Showing the position of the UV lamp, a pic of the tallest bud to show development, a pic showing the thrip damage I saw in the middle of the canopy, and a couple of pics showing the buds that will get the most UV. This is how they look before exposure. Timer is set to go 20 minutes, 3x a day at 10PM, 2AM, 6AM. My light cycle is from 8PM to 8AM.

Looking great! Very clean setup! I love a neat grow room.

^^ 420fied's right - nothing like a clean grow room - so much easier to spot pests & problems when you're not tripping over extention cords and other crap like in mine...
