I didn't wanna jump in this but.. like my unlce ben said when you cut off the leaves.. the branch at that node replaces it.
and the other thing is that your opening the canopy for light to penetrate the lower nodes and they take off towards the light.. while topping it make the plant...
If you want close to 100% consistency I would invest in one.. it's not that expensive..
Once I dial in the temp I barely loose a clone.. aside from neglect.. :wall::clap:
also depends on your method.. I use peat pucks...
It's all about the balance of chemicals.. They are at different levels at different times in the flowering cycle. and the dry/cure has a lot to do with it..
Personal preference...
