Today, we conducted our first duckweed harvest since we established our new system which includes a duckweed tank.
1. A thick mat of duckweed on the water surface.
2. Today's harvest.
3. We put the duckweed into small plastic moulds.
4. .....and then put into the freezer.
5. The duckweed tank following the harvest. We simply replace the cold frame and let the duckweed do its thing again.
The frozen duckweed biscuits are taken out as they are required. We simply snap off what we want and float it on the surface of the fish tank. The fish simply help themselves as the duckweed biscuit melts.
No, the large plastic container in the freezer is not Murray's lunch.....it's our winter stock of frozen Black Soldier Fly larvae.
