Justsayknow, upon reviewing the method as it is written that is apparently what they mean, I understood it just to be taking off the top two nodes though, not everything above the second!
As I understand topping, you remove the new growth tips above the last established node, as close to the node as possible. Basically in the following picture I would be removing everything above where the stems of the leaves on the left and right meet the main stem.
What I want to do is also remove the node that you would generally be cutting above, my reasoning for this is I wanted to top the plants at a stage they had one less node than they do now. I was hoping that doing this would keep the plant shorter than just topping above the last node.
This photo is the same plant, but with the pot rotated 90 degrees, so now the leaves that stick far out on the left and right near the top of the plant is the node I want to top just above. One of those leaves was the one closest to the camera lens in the first photo, sitting just under the node one would cut above to top normally.
I have to admit, I am now wondering how much sense there is in doing this myself. I was looking up the other day if you could do it, and came across that Uncle Ben method on a few different forums, I misunderstood it though, fuck chopping off half my plant or more. I am still open to the idea of taking off two nodes but if people tell me it is just going to stress the plant and not necessarily make it shorter than taking one node then I wont bother
Poledriver, I have read that stress has an impact on plants turning male. Plenty of good growers do seem to get 60-70% females, some even claiming more than that, which does seem to lend credibility to the fact that favourable growing conditions increase the likelihood of the plant being female. It could just be however, that more than half of cannabis plants turn out to be female. Funnily enough, I know a number of people to of grown out one plant, always unfeminised and always seemed to come up female. I hope that your baby is a girl as it would be kind of frustrating to put in the effort and take the risk for no reward. I suppose if it is a male you could keep it alive until it drops its pollen and collect it somehow, that way if you get a female next year you can apply some pollen to a couple buds and get a nice supply of seeds without impacting the majority of your smoke.
