This week we released the composting worms into the media bed to do their thing (vermicomposting). They help break down any excess and dead roots, fish solids, along with other organic matter in the beds that could otherwise produce anaerobic conditions in an aquaponics system. As an added benefit during that process, they release nutrients into the system for the plants to uptake that would not otherwise be available, mostly micronutrients and chelated minerals. Due to our hot climate, we chose a NightCrawler specimen rather than the more common Red Wiggler, who like the cooler temperatures. Didn’t take them long to run from the light.
More on the worms in the coming weeks, including how to build a DIY Worm Tea Brewer. The aerated worm tea contains lots of beneficial microbes that help the plants fight off pests and diseases naturally (not for human consumption). While you are waiting, here’s a great video from Murray Hallam about the Aquaponics Secret Weapon – the worms!
The Red Nile Tilapia are getting to a good healthy size. They are ranging now from 1″-3 1/2″ still being fed pellet crumbles and few whole pellets.
The Blue Nile Tilapia are enjoying some duckweed in addition to the pellet rations. Some are getting to be breeder size. Time to build the hatchery!
Reloading the DIY Black Soldier Fly BioComposter… papaya and other goodies we didn’t get to in time.
