Based on some of the orchids in my greenhouse, the answer may be never.
It is amazing how big a plant can grow in a tiny pot.
This Oncidium Sharry Baby (Chocolate orchid) has two 2 two foot flower spikes on a plant 2 feet wide by 1 1/2 feet tall. It is the Red Fantasy color variety that is normally 30% shorter than the common Sharry Baby.
It is in a 2 inch pot. Actually the pot is 1 3/4 inches high by 1 3/4 square at the top of the pot.
