Semi-Automatic Hydroponic Planter/Sprout Grower

Step 4 Grow Chamber Assy

The grow chamber consists of a strainer inside another container that allows access to interior and provides unhindered drainage. Drainage rate can be controlled by drilling more or less holes. An ebb and flow system can be designed by slowing drainage considerably, but this can cause water waste as the tank will still want to fill. The tank will fill and stop and the delayed flow will drain into the tanks overflow. Please build overflow protection into your chamber if you do this as the water will continue to flow through the grow chamber until the tank is filled unless it is diverted.

The Lid - Actually, it's the bottom of one of the bottles that has had a hole drilled through it to allow
the fill tube to be inserted.(Clear one in photo) It has also been cut from the bottle to
allow access to interior of the "grow chamber".

The Grow Chamber - The top of the 2L bottle. It is essentially a funnel. Acts as a mounting device
as well.

The Strainer - Essentially it stops the sprouts from falling through and in this case, dictates the
drainage rate. It could be a removable basket, which would allow for easier access
to sprouts. I will incorporate this into any future developments.

The Nut - A picture of myself would be quite appropriate here. In this case, however, it is simply a
bottle cap with the flat surface removed. It could also be used as a flow restrictor by
varying the size of the hole.
