Planter to hydroponics

Converted this basic planter to a hydroponics system. The base plate is cut to hold the net pots. The drain holes have to be closed with m-seal. Plants grow happily in this SIP.

Deep water culture. Just had to add the water plus nutrients once in the whole lifetime of the plant (seed to harvest). As the roots grow the water goes down with it. This creates an air pocket which helps in air circulation.
