Aquaponic Plant Tank Table

I’ve finished the table-like structure for the plant tank for the new aquaponic system. This structure is going to hold up the plant tank about 20 cm (8 inch) higher than the fish tank. Hopefully there’ll be enough room for the venturi aeration port between the bottom of the plant tank and the top of the fish tank:

There’s really nothing fancy about the design. I just used a lot of screws (48) to make it rigid enough.

It’s possible to mount a shelf in the middle and at the bottom of the structure. Add a few grow lights and potting trays and you have a small nursery for seedlings where they can begin their lives before going up into the aquaponic plant tank on the top.

I probably won’t add these since I have small kids and a cat running around near the system – they’re just too curious to leave stuff like that alone.

(Notice the cool little drawing my daughter did on the front – she was so proud that she could help me build this thing ;-) )

Harvesting Coriander and Spinach Seeds

One month ago I cut down my fresh coriander bush and hung it upside down in the carport. Now that it has dried for a period it’s easy to collect the seeds:

First by picking groups of seeds off the stems:

And finally by picking off each individual seed. This is the total amount of seeds I got from a single bush/plant:

I tried to split a seed in two but there’s nothing inside the seeds. Looking at pictures by other people on the Internet it seems to be normal that the seeds split into two hollow halves. It would be interesting to do a germination test on these seeds and see if they’ll come alive. I didn’t like the smell or taste of fresh coriander so I was planning on grinding these seeds into powder and use it for cooking. I think I’ll reserve a couple for germination though.

I saved a few spinach plants for seeds too. Apparently the cat likes the taste ;-) :

I chopped up the spinach plants and put them in a plastic box that I can take with me indoors:

When I get a spare moment one winters evening I’ll pick the good seeds of the stems and save the seeds for next year.

Black Plum Tomato Seeds

This year I’m also saving seeds from tomatoes. The tomato harvest was not impressive this year, with a lot of green ones, and many bad ones due to blight. I managed to collect seeds from 11 different plants:

All of the seeds have been scraped out:

The seed and water mixture needs to ferment under plastic wrap:

My small tomato seed production ;-) :

I wrote an in-depth guide here: How to Save Tomato Seeds

The seeds I saved this year was from Black Plum and Cherry tomato plants, grown from seed saved in 2009.
