Just saw this on Fox 13 out of Tampa, conserning the well known Parks Strawberry farm and store, located in Plant City, Florida. They have installed a new growing system consisting of styrafoam growing pots which each have 4 plant areas, are stackable up to haveing 24 strawberry plants grow in place of one plant previously. The units are tapered, have a center pole, features a clover leaf shape 4 unit each area where soil is installed. Each growing area is 90 degrees to the one below it. It appears that there is a drip system for irrigation and liquid fertilizer. The news report said that 40 acres of standard strawberries can now be compacted into 3/4 of one acre. On camera the growing units appeared to be about 10 inches high each, tapered at about 40 degrees inward at the bottom, each interlocking with the unit below it. It is easy to see that harvesting labor will be at a minium in that the berries will be at taller levels. I am going to go search the local paper for the name of the units and possibably a source for them also, will return with the info here if I can find it. This looks like an end to standard garden practices at this time. If you could grow 400 plants on an apartment balcony what would this mean to those without land? I did not find what I saw on the tv this morning but did find a similiar system at http://www.growpots.com/ called an agritower which features a 6 unit growing system but appear way too costly for everyday use, any how the idea is visable to you now.
