I have been looking for information on hydroponic systems were the plants are grown in pots or in trays that are easily moved. I have not seen but 2 systems over the years that have this feature. One was a million dollar drain and flood system were the plants were grown in trays. The other system was a constant flow system were a thin layer of water constantly flowed under the plants. This system was more a aquaponics system were the water was returned to a larger pond full of fish.
In most systems the plants are grown in rocks or are almost bare rooted. It seems that most plants being grown are vegies, fruits or the plants are producing a product and are not moved unless harvested or done producing.
Does anyone have a system were the plants are being grown in pots or trays or know of sources for information on these types of system? Is their a key feature to this that keeps it from being used? I am thinking the pots would restrict oxygen to the roots but in both system mentioned this did not seem to be a issue?
Here is a photo of the larger flood and drain system. The tables hold and drain the water. Their is a crain like device that can pick up whole table sections and move them to new areas. The flood and drain valves are coming out of the ground and each one lines up with a table section.
