Hey !!! So I have a Bhuth Jolokia pepper plant in a 1 gallon pot it haves around 20 flowers on it, and on the other hand I have a Red Savina plant on a 5 gallon pot which haves around 80 flowers on it and 3 first savinas are showing. So I had to do this personally to see the difference and its a huge difference, so I say if you want a good yield of peppers get at least a 3 gallon pot no less. By the way the red savina is about 2 feet high and the Jolokia is about 10 inches tall, both were started at the same time.
