Yes, it is. I grew it in a large container and let it starve a bit. Worked
fine for me. I still have a few tomatoes from the suckers I transplanted.
However, they were not as good as Celebrity. I grew Health Kick as well and
found that bland.

I started seeds from last year's crop last week and they are about an inch high
now. Of course, having a warm 'winter' in So Calif helps :-)
