Determinate tomatoes are great for canning or smaller spaces. A few determinate tomatoes are large enough to need support, but most of them can grow without stakes or cages. Indeterminate tomatoes just keep on growing and bearing fruit. They will need support and continually bloom and fruit. Whether a plant is open pollinated or hybrid matters only if you are saving the seeds from year to year.
Hybrids are usually more vigorous and prolific.
Tomatoes are very sensitive to cold and cannot tolerate even a light frost, especially when they are coming out of a greenhouse or warm home. Traditionally, Memorial Day weekend is the safe date, but most people try to sneak in a few a week or two earlier. As crazy as they sound and look, the product does help. The water filling the walls acts as an insulator, giving your tomato plants a much better chance of surviving a light frost undamaged. They will do best with a consistent supply of water, preferably provided from below the foliage.
