Aquaponics vs EarthBox – 6 week (final) results

We are now six weeks into the Aquaponics vs EarthBox challenge and there’s no big surprises since the three week results. The EarthBox plants have grown huge, I’ve even harvested them a few times. The aquaponics plants have grown, not a whole lot in size but they have a lot more leaves but not nearly as much as the EarthBox plants. I had originally planned a three month checkpoint for this competition but have decided this will be the final update for this round. I’m going to do a few improvements to the aquaponics system then replant and see if I can get better results.

Here’s the EarthBox plants as of now. The first is the Chinese Cabbage, I’ve harvested these twice and they are still growing like crazy. For size reference the EarthBox is 29 inches wide. These two plants are dwarfing the box.

Next, the Kale. This has been harvested once to make some Kale Chips and a few older leaves have been removed.

Last, the Swiss Chard. I take a leaf here and there to mix in salads and cut off old growth when it starts to go brown. I’ve got Swiss Chard growing in several places around the property.

Keep in mind these are all after six weeks of planting. The aquaponic system is working and growing but the EarthBox plants have just exploded. For the aquaponic results I’m just going to show each bed which has the same plants as the EarthBoxes (one of each per bed) plus a few other things. Media bed one:

The Swiss Chard in the back left is not the one from the competition, that was planted earlier. For scale, these beds are 37 inches wide, eight inches wider than an EarthBox. Media bed two:

The plant in the back center is celery that was a leftover core just stuck in the bed, it’s growing good and I’ll occasionally cut a stalk off for salads. Finally, the raft bed:

Overall I prefer the media beds over the raft bed, the raft does have the advantage of being easier to clean.

Over the next month or so I’ll be adding a filter to the aquaponic system, covering the sides with something other than black plastic, increasing the fish load, automatic water level maintainer, and building a screen cover over the fish tank (I caught a raccoon fishing there one evening). I’m hoping to see better results and I’m sure there’s plenty of room for improvement. Surprisingly, I didn’t get too much hate mail from other aquaponic users but I did get a few that said the systems can’t really be compared.

Here’s my take on the results. For anyone starting out and just trying to get some vegetables to grow, go with the EarthBoxes (or GrowBox). They are fairly foolproof to set up and can get you some quick success. The cost to start up a single box is under $50 all in, including some seedlings. Annually, it runs around $1 to refresh the box (not including seedlings) and they should last 15-20 years. It really doesn’t pay to make your own, but I’ll still post a “how to” for that in the future.

Aquaponics systems have the advantage of a secondary output, the fish. You can eat the fish or raise decorative fish to sell at a profit. The downsides are a much higher entry cost, higher maintenance (you have to add trace minerals, keep it clean, and feed the fish), and a single problem can wipe out everything at once.

I hope some people find this useful, again I want to state I have not received any promotional materials or discounts from any manufacturer (or store). All of this is my own opinion, my goal is to just help others get the biggest bang for their gardening buck and I’ll continue to test and compare methods to show what has worked best for me.
