As you all know, the idea of scrog is to keep your flowers and vegetation on the same level so that you can maximize the potential of your light source. The problem is that during flowering some buds grow faster than others and so you have to raise your lights to keep from burning the tallest buds up. It would be nice to keep all the flowering bud tips at the same level. Question: would the topping of a fast growing flower result in compensatory flower development in some other part of the plant in the same way that cutting a branch's tip stimulates lateral branch development during veg?

I topped 2 buds in my goin loco grow (sig link) the result was very similar to veg topping 4 calaxes came out of the top of the bud instead of just one, the buds got fatter but not taller also the frostiness was more on the buds I topped but did not notice any difference in quality

Sounds like the old optical illusion to me. Resin is created by UV rays so a "fatter" bud would have more surface area and appear to be more resiny. But since it's multiple buds the backside one quarter should be blocked off. So less plant matter in the middle where light was blocked, and no resin production. In the end my bet is on averages are the same or less on the topped but, or it would require slightly longer to reach maturity.

there are pic's in the journal, it was harvested back in Jan, I did it to see what would happen, now I know not anything I would do again but if the OP is looking for a way to even the canopy I can at least say this would work without losing yield
Hey Whiteflour, thanks for the response. I'm real interested in the relationship between uv radiation and resin/bud development. I have seen popcorn buds grow in very low light, (beneath a scrog canopy), and though their flower structure seemed much less dense compared to the buds growing above the canopy, their trichome development looked just the same as the buds growing in full light. Of course that's just my experience, it may or not work out that way in other people's experience. But seeing that made me wonder about how light affects buds. Regarding what you say about resin needing light to develop; how do we know that's true?
riddleme, thanks for your response. Just wondering why you say that you wouldn't do it again. Did topping the bud have some negative effect?

no there was no negitive effect at all, it just got fatter instead of taller
I wouldn't do it again because there was likewise no positive effect
and the plant produces trichs to protect itself and its potential offspring from various things including UVB but not limited to it, so I believe it frosted up faster in response to me cutting it, but it was not more potent
Cool, thanks. But re. the trichs being produced as a response to UVB, (or other light exposure), here's what I don't get. If the plant needs protection from any component of light, why are the trichs only produced during the flowering phase, and not right from the seedling stage, and why would they be concentrated around the female flowers? Do flowers require a protection that the rest of the plant doesn't? It just seems odd, that's why I ask. I hope the question isn't offensive.

I've got a couple now that have been showing resin and stinking bad from about the 16days or so. Hard to tell with the eye but you can see it with the mag. First time I've ever noticed that this early though, so I'm not sure if it's from being blasted with 1000w this early or just the strain.
