how deep should the medium be

[Ritter]

Hi Ron I can't thank you enough for all the help you have been to me. A big thank you for all the
information you have supplied. I have one more question to ask at this time. I purchesed an Ebb and
Flow System that is 5 feet long and 7 inches high. I plan to use either Pumice Stone or grow rocks,
the question is how deep should the medium be for vegetables. and cantaloupe? Thanks C Ritter
