    that foam does not look like safe to use for food. it has lots of chemicals.

    You may save a lot of money construction hydroponics yourself rather than buying it.

    this is really good. i was just wondering, can i grow tomatoes using this method? how often do you change your nutrient solution? or is it a one time pour of the nutrient solution?

    would this material be to small to hold up the pots? I'm having a heck of a time finding the right size for a bus boy tote version.

    The downside of hydroponics is you will need to purchase "plant food" or nutrition and supplements which are more costly.
