I think orchids just do what they want whenever they are ready. I'm not sure about Bob Betts, but ones that bloom as soon as the growth is mature, or the buds start forming before the growth is even hardened off, it's hard to get all the growths to bloom at once, because all the new growths don't necessarily start growing at the same time, and therefore don't all mature at the same time, and so they won't all bloom at the same time. For the seasonal bloomers who harden their growths and then rest for a bit before blooming, there might be a trick to getting them all to bloom at the same time, but I'm not sure. As far as I am aware, they will just bloom when they are ready, and there's not much you can do to change that. Maybe somebody with more experience in this will tell you how you can fiddle with the light and temperature to get them to bloom together, but as far as I know, there's not really much you can do.
Does Bob Betts bloom as soon as the growths are mature, or does it take a rest period after the growths harden off before it blooms?
