Difference between jelqing and stretching

What is a difference between results with I can gain from jelqing and stretching? How do you use this two techniques to gain the maximum results? Is there any ratio between these two which will yield the best results?

Just start with the newbie routine, and you will figure it out with time and persistence.

Also look at this lighter newbie routine, as the regular is too much for some guys (including me):

NEW newbie + advanced routine

Jelqing is bursts of tension and pressure into the unit.

Stretching is sustained tension into the unit.

Weights and/or extenders are much longer sustained and measured tensions into the unit..

Pumps and Clamp are sustained and measured pressures into the unit.
