Aquaponics - Duckweed - direct composter

Having dried some duckweed by spreading it out on some concrete for a few days, the next stage in creating my direct composter is using my cheese press to bring it all together. My PVC cheese press has seen a few different purposes in it's lifetime, but this one looks like it might be the one it retires to.

The duckweed shrunk down to a quarter of it's former live self.











I found my PVC pipe with holes that was formerly a cheese press, and rinsed it thoroughly.










I filled it with the dry duckweed, and planted it into the growbed.











The day after tomorrow, I'm off on an adventure to the other side of the continent, but tomorrow, which is really the day after tomorrow a far as this experiment goes, I'll check to see if the worms like their new feeder. But really I'll be somewhere else.




120 Things in 20 years is wondering if anyone is actually following this convoluted narrative.







120 Things in 20 years thinks that as far as it can tell, it's made a worm motel.


Aquaponics - Direct composter - duckweed drying

My system has only one fish, and I'm getting a little worried about my growbed's worm population. I'm not confident there's 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 wouldn't 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.
