The holes are in all the corners on the bottom to catch circling roots and force them out to be air pruned. The new roots growing out also get caught in the holes on the sides, repeating the effect.

Moding the flowering container is not necessary as the base of the root mass i build in veg will fill out up to a 5 gal bucket though results are better in a 2-3. Yucca becomes a necessity in every watering. There are alot of good guidlines to go by. Which ones to use is a matter of what youre trying to achieve. I try to build bushy plants with big canopies and massive root systems without them getting too tall. I pay no attention to time as far as when to transplant.
