1 Plate Aquaponics Grow Bed

1 Plate Aquaponics Grow Bed by IWorkInPixels Feb 1, 2013

Description

This isn't done yet (I still need to add connectors for hoses and to attach each tray to the frame of the aquaponic garden), but it's a proof of concept of a printable tray with integrated bell siphon. This grow bed is big enough to hold some decent sized plants, but totally printable on a Replicator 1 build platform.

I design things in my free time, just for fun. If you like my stuff, send me some DOGE. It'll totally make my day! Thank you.

I agree. Maybe run a small triangular circle on the bottom around the hole to create a drip edge so any leaks won't follow the bottom of the bed to funny spots. I like any leaks to follow the pipeing/tubing to get closer to where it belongs in the sump.

Maybe also add a ring on the inside for a rubber o-ring or to pack some vasiline into to make the stand pipe more water proof?

Actually, this has me thinking: if I want to use separate pipe out the bottom anyway, why have a stand pipe in the print at all? I could save a lot of print time by omitting it, and then you just push your pipe through to the appropriate height, seal it by whatever means are convenient, and off you go.

I think a round standpipe in a triangular 'bell' would probably work just fine as long as the volume of the 'bell' is at least twice that of the chosen PVC pipe stand pipe.

It's all in how you plan on using it in the end. There are just so many design options to pick from...

Instructions

1: Print as many of these as you would like grow beds in your aquaponics setup, in opaque PLA (algae growth = fail), and at 8 shells. Make sure these things are waterproof!
2: Place each bell into the little slot provided for it.
3: Fill each grow bed with expanded clay spheres.
4: Hook up an input hose to the first tray, which will carry water pumped up from the fish tank(s).
5: Stack the trays so that the drain from one becomes the input for the next.
6: You've got yourself some grow beds! Cycle your system a few times, and then get some plants in there!

A few suggestions...

Make the stand pipe triangular and put it into the corner.
Make the siphon bell triangular as well.
Make a 'mesh' gravel guard for the corner.

Maybe make the underside of the stand pipe be able to accept standard PVC pipe or tubing so we can drain the water away to the sump/tank. It would need to be recessed up into the bottom so the flat bottom is maintained for printability.

Actually, the round stand pipe was made circular specifically so you could push a PVC pipe in from the bottom if you wanted... just make the ID of the stand pipe slightly more than the OD of the PVC you intend to push in. As for the gravel guard and the recessed pipe acceptor, those are great ideas, I will get to work on them as soon as I get a chance!
