How carefully these studies have been done is a real concern, and I have yet to see anyone clearly show the mechanism behind this. In Rosenthal's Grower's Handbook he notes a PhD thesis by a guy named John Lydon (I'm assuming this person isn't also the lead singer of the Sex Pistols) who found that the potency of the final product increased in direct proportion to the amount of UVB that was used during flowering. Since UVB is more intense at lower latitudes and in the earlier part of the summer, it was concluded that plants grown outdoors should be forced to flower in early summer (June-July), when UVB is naturally most intense.
How this carries over into an indoor grow is less clear. I have read many testimonials from people who have done (IMHO) fairly dumb things with UVB lamps and ended up cooking their plants and/or themselves. Rosenthal recommends using a cfl based UVB with a total wattage no greater than 10% of your total lighting system. I use two 25w UVB cfl bulbs in reflectors along with a 600w HPS. These are bulbs usually used for reptiles and are not expensive, but you need to make sure they are B. While other blue and violet wavelengths may help, Lydon's work showed that UVB specifically was related to increased potency. I turn mine on when I'm done working in the room, then turn them off after a couple of hours. I have them placed about 24 inches from the canopy and after 14 days I do not see any signs of leaf damage. But as Captain points out, I won't have anything to compare to in the end. In the future I may try to set up a system where I can directly compare with and without UVB.
New pics of the girls tonight. Exciting stuff happening!
Girls are vibrant and proud. Flowering is now finally indisputable. Aroma in the room is heavenly. Pulled back some branches and rotated slightly, otherwise, just letting them be.Attachment 296724Attachment 296725Attachment 296726Attachment 296727Attachment 296728Attachment 296729
How's the little pheno dwarf coming along? You haven't mentioned her lately. I'm anxious for your harvest. Bet it will be comparable to an outdoor grow. I've had friends who would drive miles to their crop. It was a good location, full sun, rich soil right next to a stream, but they were only able to do that because their place of empolyment had shut down. Now that they're back to work they're ' in the closet' again. I wish there was a way you could do a big outdoor grow in 2014. No height/size restrictions, you'd be in your glory. My friends were in awe at the size of their plants & buds. Dried harvest wt, a little over 60 lbs. They never said how many plants they had, but they weren't expecting that much weight. Just wishing you could enjoy that same experience! (As I've been sitting here watching it snow its ass off!!!!) :) :) :)
Just saw the pics! Not just tall, but nice & beefy! They ARE going to be comparable to outdoor buds! That's an experience I can't wait for you to have! Maybe legalization will happen in the not TOO distant future. We can only hope, sign petitions, & vote for candidates in favor. Removing ourselves from the U.N. might help :( I'm really upset with them. Read the thread about Uruguay's legalization. Yea for Uruguay! Boo on the U.N.! OK, I'll jump off my soapbox (for now!) :) :) :)
Catbuds presently I'm doing a legal grow for a patient. Fortunately I live in a state that is at least trying to peek it's head out of the Dark Ages. I do dream of an outdoor grow, and I am convinced someday it will happen. There are some options I have down the road. I can apply for a license to grow "commercially", but it's expensive and the competition is fierce. In my neck of the woods, growing anything except grain is very difficult. We have the unfortunate combination of extremely dry air, clay-rich soil and seasons which change suddenly, especially autumn. Night temps in the summer still routinely drop into the 40's even in August. Average last frost is late May, average first frost is Sept15th. That's a very short effective growing season. Gardeners here really pride themselves because it is a very challenging climate to grow most anything well (tomato growing is so difficult it's like an Olympic event amongst the gardening crowd). But there is a high probability that I will be moving to the desert Southwest or SoCal within the next 5 years. Depending on where I go I might have better opportunity for an outdoor grow.
As for the pheno dwarf, it also suffered the indignity of being knocked off of it's stand by two of my cats who were chasing each other around and somehow got into my veg. room. Lost two branches.:( Cats lost 1 or 2 lives.;) A long-time grower who has been guiding me here looked at it and thought I should throw it in with the flowering girls and see what happens. I believe Catbuds that you gave me the same advice. Well, that's good enough for me. Into the flowering room it goes. It's actually flushing with new growth, but even that looks odd. I'll post a pic and if people have comments/warnings/suggestions I'll mull that over before actually moving them into the budroom.Attachment 296767 Keep in mind this plant is the same age as the girls currently flowering. Under a loupe it does display what appears to be female pre-flowers, but no stigma.
Ahhh, putter tats! Just can't keep their little fuzzy butts outa trouble! My two are the reason I didn't just build my own tent. Have all I need to do that, but they would go right through it! they seem to know when they can get away with murder & once they're spoiled rotten, they're into EVERYTHING! But the badder they are , the more I lover them! LOL!
-- Sometimes mutants are sterile. That could have been her issue from the start, made her more susceptible to heat/cold stress. Time will tell. Worth watching though.
-- Damned! Sam seems to have known we were talking about them! Just chased him off the fridge, trying to knock the lamp in the floor. But that's alright, I have a spray bottle & I'm not afraid to use it! :) :) :)
P.S. Almost forgot to say, I love your avatar! Nice trichromes!
Plants starting to shed leaves. I've been warned that this will happen as flowering progresses, but it's alarming nonetheless. Otherwise they look fine and the flowers are starting to explode. The aroma is getting noticeably stronger. Not as sweet; darker and spicier. Tonight I'm going to put my good macro lens on my camera and see if I can get some close-up shots of the flowers and trichomes.Attachment 296895
Close-up of bud formation. Capitate trichomes becoming much more noticeable. The stigma of the pistils are Medusa-like. Good times.:smokin:Attachment 296896
