From Mike in San Antonio:
“Bro thanks a million!!! Very excited about my worms. Almost turned around and bought more! LOL. Here are some pix.
Very excited about my Garden.”
Thanks for sharing!
In production since last week this TexasRedWorm Flow Through 2 has been a work in progress for several years. I have been looking at examples of flow through bins homemade and commercially available for some time. This latest design is the latest version predated by several prototypes. This latest evolution has been a success thus far. I ended up purchasing the metal racks from Costco for about $137. Easy to assemble and very sturdy, these were a great buy at a good price. I spent about $70 on hardware (nuts, bolts, screws, washers, 20′ of .25″ cable, and cable clamps). Key to a long lasting box built around the metal rack, were cypress 2×6′s from TexasDozer.com cut from my dad’s saw mill. Cypress will not rot and in it’s natural state (no chemicals used to preserve the wood) and will not leach out anything harmful to the worms or castings.
The cutting diamond bar was fabricated out of scrap and square tubing for the guides. This will be pulled with winches mounted to both sides of the rack to cut and harvest castings from the bin.
Two mason tubs purchased at Lowe’s for around $13 each rest on the bottom rack just below the flow through bin to catch castings. The bottom of the bin was lined with newspaper and worms and compost were added. We will let the worms go to work for several weeks feeding compost as needed. Over the next few weeks the newspaper will break down and the bin will be ready to harvest. For the initial harvest, remove by hand the newspaper from under the screen. Use the winch from one side to move the cutting bar across the bottom of the bin one time.
Worms are for more than just fishing. I’ll be at The San Antonio Botanical Garden tomorrow to discuss composting with worms. We’ll be talking about how worms can take kitchen waste from the trash can to the garden and add life to your soil and plants. Soon you’ll be backing up your pickup to scavenge manure piles and livestock stalls to feed your own brood of humus producers, and you’ll be producing some of the finest vegetables and plants around.
I have tried several models of flow through systems and continue to tinker to get the results I’m looking for. The idea is for the finished castings to fall through the grate at the bottom of the bin and the worms to work towards the top of the bin.
Materials: square metal tubing, plywood, braided cable, 1.5″ self tapping metal screws, small I beam we found for the base bar to mount winches, and 2 winches (one we salvaged and another from Tractor Supply @$20) for pulling each direction.
We welded a bar to slide along the bottom of the bin to agitate the castings through the grate. I have tried other versions without the cutting bar, and castings tend to get clumpy and stuck. Stay tuned for the big reveal when we add worms and a few finishing touches.
This Summer has been brutal, and can be very stressful to your worm bins and beds. Redworms perform best in temperature ranging from 40 F – 80 F., and keeping them moist is essential to their survival in these less than ideal conditions. Don’t drown your worms, but error on the side of wet in this blistering heat.
I posted earlier, how to keep worm bins cool by adding frozen water bottles. This works great, but w/ temps hitting 100 in the shade this week, I began having to use more and more ice bottles. I was running out of freezer spa, and was able to convince my wife to let me bring my smaller bins indoors.
My larger worm bins kept in full shade, have faired well. Size of the bin is a big factor. Larger bins or containers will naturally have more volume to allow for greater insulation and protection from extreme temperatures. Smaller bins will “feel the heat” and not have as much buffer or room for protection. I keep old rugs on top of the bedding that are sprayed down daily to keep moist and cool. Add a few more inches of mulch to in ground worm beds and keep as moist as possible in these tough conditions. The mulch added to worm beds or flower beds will add organic matter, protection, and an additional moisture barrier.
Thank you to all who came out to the San Antonio Botanical Garden this weekend. I have included some links and attachments to dig a little deeper into some of the topics we covered on Saturday.

Join TexasRedWorms.com at the San Antonio Botanical Garden this Saturday, July 23 at 10:00 am. We will be teaching how to set up your own red worm composting bin, and how to compost with worms. Learn how to turn your kitchen waste into rich worm castings that will condition the soil, and fertilize your plants naturally.
10 am—noon. Start turning your waste into rich worm castings for your garden and plants. Red Worm composting from
TexasRedWorms.com will show you how to make your own worm bed and bin, how to feed, care for, and harvest your own steady supply of worm castings. Limit 30 participants. Fee: $20. To register, please contact Sasha Kodet at 210.207.3270 or sasha.kodet@sanantonio.gov.
With a few minutes and fewer tools you can set up your own red worm composting system in any raised bed.
Materials:
Tin snips or box cutter
Plastic planter or bucket
Shovel or other digging tool
Stone or cover for the in ground bed
Find an old plastic planter and cut the bottom out.
Find a well drained spot that is protected from afternoon direct sun. Dig a small hole big enough to bury the upside down container. Add some shredded paper products and some compost. Moisten your mix and add worms. Cover w/ a paver or stone to keep out critters, and protect from elements.
Depending on the amount of worms, a handful of kitchen scraps every week or so will be plenty to start. As your worms grow and reproduce they will require more frequent feedings. Do not over feed. Be patient and when the food is processed by the worms, add a few more kitchen scraps. Keep an eye on moisture. If kept out of direct sunlight, the food scraps will usually provide enough moisture for your worms. Worms like it wet because they breathe through their skin, but will drown in standing water.
Red Worms (Eisenia fetida), European Nightcrawlers (Eisenia hortensis), and African Nightcrawlers (Eudrillus eugeniae), are all excellent composters. These worms vary in size, w/ Red Worms being the smallest and possibly the least picky. Red Worms ease of care and ability to handle a wide range of temperatures make them a popular composting worm.
European and African Nightcrawlers are larger worms. European Nightcrawlers are popular w/ fisherman, due to size. You’ll find their larger cousin (Canadian Nightcrawler) in bait shops, as well. European Nightcrawlers can be used for composting, but thought to be less efficient than Red Wigglers or African Nightcrawlers.
African Nightcrawlers are a tropical worm that thrive in warmer climates, need to be kept in temperatures above 70F and will start to die off at 60F. They are the choice for many commercial worm casting producers that have access to climate controlled facilities. All three species or varieties can be prolific in the right conditions, and make excellent composting worms.
