hello,

When LR first broke out on the scene people were growing them in the large "super gulp" cups from 7-11. I would recommend nothing smaller than 1 gallon.

The last group that I grew out were grown in two gallon buckets. They did not become root bound, but certainly filled the pots.

The more root development, the higher your yield will be.

As far as your 2 1/2 foot tall pure LR. I would like to see pics. I have been apart of the growing of several generations of LR and have never seen one grow to be over 16-18 inches tall.

I would suggest using the big one for breeding, you could end up stabilzing the trait. With enough work/time.

Take care

Peace
