All things considered with indoor grows, stretch is overrated...

What I mean is, it doesn't impact the plant as much as many growers seem to think. (in my opinion..) By the time the plant grows into a mature size, it's common for many of the lower nodes to be cut off completely, and supports are often added in the form of nettings and tie downs/ups.

This means that it really just doesn't matter if in the beginning the seedling lopped over or stretched a little, because it just doesn't really matter much at all in the end and likely doesn't affect the flowering capacity of the plant :)
