Aquaponics Direct composter duckweed drying

My system has only one fish, and Im getting a little worried about my growbeds worm population. Im not confident theres enough fish waste going into the system to feed them all.

What I thought I might try is creating a small compost bin directly in my growbed to make sure the worms have enough to eat.

I have a lot of duckweed growing in my system, and that one fish has to power the new bigger growbed, and the duckweed.

Duckweed uses quite a bit of useful nutrient so I thought I should remove some, and add it back into the system via the composter.

 I pulled out a quarter of a bucket or so of my duckweed from the system, and dumped it on some dry, sheltered concrete to dry.










I need to dry it first to kill it, because the direct composter will be a small container full of holes, sitting directly in my growbed. That means it will be damp, and the duckweed might just stay alive.

As I understand it, worms feed on the stuff that feeds on rotting vegetation so live duckweed wouldnt work so well.


120 Things in 20 years seems to be growing plants for feed to grow other plants. I think I finally developed a way to make growing vegetables as inefficient as growing beef.

Aquaponics New system at two months

In a couple of days my new system will be two months old.

I wasnt sure how it would go being on the wrong side of the house and in shade for all but a couple of hours a day, but it looks like it might be ok.

This is the original empty growbed two months ago.

And now it looks like this.

The lettuce in the foreground went in as store bought seedlings, and the rest was from seed, but I wasted a lot of time before I actually sowed them.

We have started harvesting leaves from the lettuce and within a week or two we should be picking rocket as well.





The growbed is around two metres long and a little over a metre wide, so it should keep us in salad greens with ease.

Ive also planted a few sugar snap peas at the back because I like to eat them when Im doing anything with the garden. Theres not enough to harvest but I enjoy picking something and eating it at the growbed.

Also at the back Ive planted quite a bit of basil, some coriander (cilantro), and a few other herbs.

Thats all. Just a quick update.
