Creepy Crawlies | Black Soldier Flies and African Nightcrawlers | DIY Worm Composting Bin

So a while back, we had made a DIY Black Soldier Fly Biocomposter and posted the DIY part here.  We chose the Black Soldier Fly (BSF) because they are insatiable composters and we have more to compost than our small worm population can handle at the moment. We have weekly harvested microgreen flats, add to that the lower lettuce leaves, bolted lettuce or herbs, damaged plants from the wind or rain storms… meaning we have lots of vegetative compostables that we certainly don’t want to add to any landfill!  So, we have recruited more composters that are native to Florida. Who doesn’t like free? Just as a reminder, this is what the DIY BSF Biocomposter looked like.

BSF Biocomposter DIY –

At the end of June, we finally layered in charcoal (up to the top of the horizontal part of the drain pipe) and chunky coco coir (a couple inches) and then some spoiled papaya and other food scraps. Afterwards it was set outside to do it’s thing.

On July 20th, we had our first migration and collection of the pre-pupae from this small  biocomposter.  We did not buy any BSF larvae or eggs, just set the container outside in the shade near a bush with some fruit and food scraps where the adult Black Soldier Fly (Hermetia illucens) found it and layed eggs. 

Day 32

Day 31 the first two appeared in the collection bin. This is Day 32 – the next night’s harvest.

This was 2 nights later – Day 34 – looks like full production! Chickens are loving it!

The migrate at night right into the collection bin. So cool!

Success so far!  Looking to build 2 larger sized ones for outside the harvest end of the hoophouse and maybe even a hatchery and propagation station! This would allow some of the larvae to pupate into mature flies and keep that cycle going. Once our chickens and tilapia have had their fill, we may even try to sell them to other BSF enthusiasts that live in short season climates, as well as exotic pet or other livestock owners looking for a sustainable high protein feed (up to 42%).

Although the larvae are also edible for humans, we will not be producing any for human consumption 😉

Adult BSF on the outside (and hopefully going in to lay some eggs) The chickens are hungry!

Some interesting tidbits:

  • The adults only live 5-9 days
  • The adults have no mouth
  • The adults can lay up to 900 eggs.
  • The BSF do not carry human pathogens.
  • The BSF larvae in the larger of the containers can eat up to 2 pounds a day!
  • The BSFs can eat almost anything, even meat, unlike composting worms (who get no dairy, fatty, meats, oils).  Truly nature’s best warm weather composters!

On to the next crawlies….though none are truly creepy!

Bedrun View in the Bag of ANCs

In mid-April, we picked up one pound of African Nightcrawlers (Eudrilus eugeniae) to start composting our harvested microgreen trays (now relegated to the BSFs, they are faster). These composting worms are being used to transform a waste product (our vegetative farm scraps) into a nutrient rich vermicompost to use again to amend of our soil-less soil.  The bag pictured above was bed run, so there were cocoons (worm eggs) and worms of all sizes in there (along with a few BSFs that snuck their way in). The BSFs are commonly found in the same environment as the ANC when they are raised outdoors in Florida.

One feeding of paper and food scraps (about 4 weeks after transitioning them to the bin and feeding bi-weekly). This was covered by a damp papertowel to keep out any fruit flies that will also want those scraps. We usually put the food underneath the shredded paper   for the same reason.

These pictures are our DIY worm bins we are currently using. The worms migrate from the bottom to the top as you fill with peat and feed. These bins have 1/4″ holes drilled in the bottom to allow for drainage and migration of the worms. When the bin is full almost to the top, you add a new bin on top of the old and they keep migrating up to where the food is, while you harvest the compost and worm castings in the lower bin. This keeps repeating by stacking the bins. We have found that this a quick and simple system that is great for DIY at a home scale. However, we don’t feel it would be practical on a farm scale. So, as soon as we make a couple sifters and some special buckets, we will be repurposing this worm bin for staging worms for sale. We are switching to a bucket methodology to get a better handle on inventory and purposeful production, which is difficult to do with bedrun and the current stacking bins.

The cardboard is to give them adequate airflow, darkness and prevent too much evaporation. We have the two containers sitting inside a large box to help contain any escapees. Lights on at night helps with that too.

 

Happy Composting!

Farm Update | New Honey Bees and How-To Pages

We had a new Honey Bee ( Apis mellifera ) delivery in the early part of the week from the Bees Choice.  Yay!  There were some minor delays in getting queens this year due to the massive pesticide incident in California during the end of the pollination of the almond crops. Someone “accidentally” killed 80,000 colonies by tank-mixing pesticides and spraying during the daytime hours while the bees were out foraging. That’s a LOT of bees when you multiply that by 40,000-80,000 per hive. So sad. 1,300 beekeepers suffered losses. This also started the initiatives from the White House to Save the Bees!  Without these wonderful pollinators, the United States would be out of food in less that four years!

This brings me back to our little story…in Florida, we have an africanized honey bee drone population for queens to mate with (a no-no), so we have to buy queens from areas that are not yet infiltrated or ones that were artificially inseminated to help dilute this current drone population. The goal is that the more beekeepers we have in Florida that follow the best management practices, the more we can dilute the undesirable traits of the africanized drone population. The beekeepers in most of the southern states have to order queens, in addition to the 1,300 beekeepers that lost their colonies in California, which caused an unexpected high demand and therefore, low supplies and delays. Our queens made a long journey from Hawaii to be with us.

Our two 5-frame NUCs should be ready to be transferred to their new lavender 10-frame Langstroth hives very soon.

This week, we were at Mote Marine’s Aquaculture Park (sturgeon facility) and ECHO where we made some new friends and met up with the Phil and the crew from Morningstar Fishermen.

The remainder of the week was a clean up week since it’s a holiday weekend – Happy Birthday America!

  • Lots of mowing and weedeating since the grass, pastures and weeds grow REALLY fast down here in Florida with our hot, rainy summers. By the time you finish, you have to start all over again if you don’t get rained out in the process. 😉
  • Getting materials for next weeks projects – end wall posts to be installed. Yay!
  • Procured a walk-in cooler that we disassembled and transported most of last week that needs a new home in the Quonset. Still trying to figure out exactly where.

We’ve added some Resource pages under HOW-TO link in the menu above. Pages that have links are completed, those that do not are planned and we hope to keep adding to these as we go along. Those following us on this blog and Facebook will be the first to know! So, don’t forget to follow us and LIKE us, if you haven’t already.

Currently, we have:

Florida Gardening – planting calendars, guide for herbs, guide for vegetables/fruits, integrated pest identification and options and other useful online resources that we have come across. More coming soon

Florida Beekeeping – calendar of blooming plants, FL BMPs, diseases and pest of the honey bees, beekeeping associations, and other useful online resources that we have come across.

Aquaponics – here we plan to add Q&A type info from the questions we tend to be asked more frequently. Got ?s, let us know.  The most specific information on aquaponics will be in the DIY Projects section for those that have attended our classes.

Recipes – here we plan to add recipes for many of the items as we get ready to harvest to  allow everyone to see the versatility that heirloom vegetables and fruits can have.

DIY Projects – here we plan to put all the handouts and materials from our various classes. It will be a members-only section, log-in information will be provided at each class.


Still planting and harvesting microgreens (sunflower, radish, broccoli, wheat grass available) and our 3 foot basils (genovese, citrus and thai available). The citrus basil knocks our socks off. It’s really flavorful. Let us know if you want to pop by for an order.

Farm Update | Worms in Aquaponics and Worm Tea and Fish Update

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.
