That method consists of

30 % cheap

Leading to 100 % pure win. Awesome. I'll give that one a shot this summer.

I don't understand how does that glue thing work, can someone tell how the pollinating happens?

Pepper flowers are "perfect" having both male and female components. This is why pepper produce inside without wind, insects, or other intervention. Wind and insects cause cross pollination by moving the pollen from flower to flower.

Oh, so flower pollinates itself?

Yes.

That is very useful. Im gonna try that this year, and i hope that works... :roll:

It does work! :-) I tried this technique last year and it worked perfectly.  The flowers pollinated themselves and produced nice fruits full of "pure" seeds (depending of course, on the purity of the seeds which generated the plant itself).

The only thing you need to be careful about is not to glue the flower to the calyx, otherwise the petals won't be able to fall off and that might cause the fruit to fall at an early stage.
