I think you mean Perlite. That I am familiar with although, it doesn't work to well in flood and drain systems because it floats. Though even at half and half if the zeolite bonds with the elements in the solution it will make them unusable to the plants.

I don't know whether any of the three tomatos are determinite or not

Determinate varieties of tomatoes, also called "bush" tomatoes, are varieties that are bred to grow to a compact height (approx. 4 feet).
Indeterminate varieties of tomatoes are also called "vining" tomatoes. They will grow and produce fruit until killed by frost and can reach heights of up to 10 feet although 6 feet is considered the norm. They will bloom, set new fruit and ripen fruit all at the same time throughout the growing season.
