Air lift pump for hydroponics

 Air lift pump is an age old system used to pump water to a higher place. This system is a non effective system, but for hydroponics where we need to push water drop by drop and not in bulk, works best.

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.
