Aquaponics-Grow bed maintenance

I had to make some changes in the greenhouse this winter which gave me the opportunity to take a closer look at my grow beds. The grow beds had a high concentration of fish solids making it difficult to maintain clean water and a proper ph balance.

These tanks have been in operation for over 3 years so I guess that’s not bad considering how lax I have been cleaning the swirl filters, which removes 80% of the fish solids. Note the mud like substance in the photos as well as the algae buildup in certain areas of the grow bed.

The only real option I had was to remove the grow media and rinse it through strainers to remove as much of the solids as I could before returning it to the grow bed.

Hopefully I will never let it get that bad again, but I know my fish and plants appreciated the clean out.

 

 

 

Maybe I Should Have Gone Bigger

When we first built our greenhouse on the side of our house a few years ago, I thought this is more than enough room for what we will ever do in here. Wow, was I wrong!

Putting in the three 300 gallon fish tanks, with the grow beds, gutter garden, and potted plants seemed to be about perfect, but this year when an opportunity presented itself to acquire some 4 to 5 year old citrus trees, I took it. I now have a total of 6 citrus trees which must be protected from our mid-Atlantic winters.

Lemons, limes, mangoes, and banana trees have made a home in our greenhouse. To make room I had to eliminate one fish tank and build a step-platform to hold the trees. I still have 2 fish tanks which is more than adequate to keep my grow beds alive. Here are a few pictures of our overcrowding.

 

 

 

Aquaponics-Can’t neglect the system

This last year  has seemed to quadruple in speed. So much has happened and changed that I did not even realize how much I have neglected my aquaponics systems in the greenhouse.

You know you have not been paying attention when you find moss growing on your grow media! The grow bed above “B” tank in my greenhouse has collected a large amount of fish poo in the grow media, allowing for moss growth on top and around all the edges.

Honestly this past winter, I did not grow much in this bed and kept feeding the fish as normal.  The tank is currently over-crowded with about 30 adult tilapia fish, which produce a large amount of waste.

I have a swirl filter attached to the system to help eliminate heavy solids, but I have not kept up with cleaning and draining the swirl filter on a regular basis. The swirl filter with an over-populated tank should be drained every other day and cleaned about once per week. Through the winter, I probably drained it every 2 weeks and cleaned the filter once a month-very neglectful on my part. Truly I am surprised I have not lost fish from the tank as the ammonia levels are way out of control.

I dug down into the grow media a few inches and found the majority of fish waste was contained in the top 2-3 inches of the media.  I took off the top few inches and rinsed it thoroughly before replacing into grow bed.

I  added a pound of red wigglers to the bed, which should reduce the amount of solid fish waste, since they feed heavily on the waste. Planting the bed full of herbs or other plants will have a significant impact as well.

Over the course of the next few weeks I will drain the filter daily and clean the filter two to three times a week. I am hoping within the month this will clean the majority of the waste from the system and get it back in balance.

 

Dreaming of Fish Poo Plants

I love to hear stories from people discovering the joy of aquaponics.

Written by Jackie

Living through our 20’s are tough for most of us – it’s the time we make some of our biggest decisions. We have moments of clarity and joy, scattered with moments of inquisition and uncertainty. We question the time we spend on this planet earning money, and whether more money and stability is worth sacrificing happiness. Through our love of the environment, science, and community, Sean and I discovered aquaponics, and the possibility of a tiny business selling plants grown from fish poo. Sounds exciting right?!

Catfish Added to Aquaponics System

For the last five years I have fueled my aquaponics entirely with Tilapia Fish, but this year have seriously considered expanding our systems with catfish. Have not as of yet, but probably will before summers end.

After a little bit of a wait, I finally got some catfish to help power the system. They’re really small at about 4 inches. Not sure if we should be calling them kitten fish at this stage. I’ll have to check on that. After the big fish kill from the aerator diaphragm failure, I wasn’t sure how many hybrid carp I had left in both tanks. So to make room for the catfish, I emptied the tank with the least amount of fish “stashing” most of the water from the 500 gallon tank into the rest of the system. Earlier in the day, I noticed the sump tank was low and figured if I clear the swirl filter to lose about 100 gallons, I could isolate the fish tank by closing the valves and use a pump and hose to empty it into the rest of the system saving my…

Preparing for winter-too much to do!

I am taking advantage of the nice-but cool weather today to start preparing the suburban homestead for winter. Bees, chickens, rabbits, fish, the greenhouse, the aquaponics systems the garden, canning, freezing, dehydrating, and I am sure there are a few other things that will need my attention over the coming weeks.

This morning started at 5:30, fixing breakfast for the little woman. Yes she still works outside the home, which is why I became here “Homestead Hero”, as she calls me. Hero I am not, but it is a full time job to take care of a homestead-even a small 1/5 acre suburban homestead.

After getting her off to work, its time to gather food scraps and greens (grow in the garden and greenhouse) to feed the chickens. Taking food and water to the chickens is not as easy as walking out the back door since we can not legally keep fowl on our property. (In Baltimore County-must have 1 acre for any chickens) So I have to take a short drive of about 1 1/2 miles to get to the chicken coop on our friends property. This isn’t so bad and I really do not have to go every day since we installed the solar electric door to let them in and lock them up at night. But it’s nice to feed them greens and scraps to keep our feed bill low.

Once back from the coop, I focused on getting the bees wrapped all warm and toasty. We have had a few nights now at 30 degrees, so why wait until the last minute.

I start the wrap with a layer of 2″ foam board around three sides. This is held tight with a metal plumbing strap. Then I can surround the hive with straw bales. These serve as a great wind break and an insulator for the cold weather accompanied by high winds that we usually have here on the east coast.

In the third picture, many of the bees came out to see what was going on, almost looks as if they are getting ready to swarm, but they quickly settled back inside to their routine.  I was going to start feeding them today, but with the activity I will just wait until tomorrow before I disturb them again.

While I was outside, I just checked on the rabbits. We have a mating pair of Florida Whites, of which our female is currently pregnant. She is due on the 27th, so I just added some straw in the cage so she could build a nice comfy warm nest to deliver the litter. I have the plastic wrap put up but have not surrounded the hutches with it yet. That only takes a few minutes to unroll and attached to the outside of the hutch, so I can wait until later this month.

Chickens, bees, and rabbits-check, check, and check. So on to the greenhouse. I have not been real active in the greenhouse over the summer, since all of my attention has been devoted to the outside garden projects.

Of course the last few weeks have been filled with canning, freezing and dehydrating our spring and summer crops. “crops” that makes it sound like we have so many acres, but we have just enough for one little homestead hero to handle.  You would be amazed at how much can be grown on a 1/5 acre!

Anyway, back to the greenhouse. I wrote a couple of months ago about our cherry tomato plant in the aquaponic grow bed. I figured today was a good day to say goodbye to it-after 11 months of growing and fruiting. Yes it was still delivering cherry tomatoes, but the growth had taken over the greenhouse and the vines had rooted in several places throughout 2 grow beds.

winter 008It took some time to clean out the remains of the tomato plant, along with some lettuce, spinach, and mint that the growth had been hiding from me. But now that the grow beds are empty, except for a thriving mint plant in one corner, I can start to plant for winter growth.

Our outside Bean Tower during season

While working outside I found some bean plants that had sprouted around my outside grow tower. I guess when I let some stay on the vine to dry for use as seeds next year, they must have fallen off and germinated in the ground around the barrel.  There were six small plants that seemed to be thriving, even after the frost we encountered the last two nights.  I thought this would be a perfect time to try green beans in our aquaponics system.

I installed one of our larger tomato cages into the center of the grow bed. Then I dug up the 6 bean plants and cleaned the roots for transplanting. This will be a first for me trying green beans so I am excited to see how well they do.

The other grow bed, with the mint in the corner is now planted with seed for lettuce, mescaline, spinach, and arugula. It is nice to be able in the winter to feed our chickens and rabbits fresh greens.

Part of preparing for winter is also thinking ahead to spring, so today I had a full load of wood chips delivered. I use these to spread on paths and walkways between the raised beds, as well as around fruit trees to keep roots warm in the winter.

Anyone like pumpkins this time of year? I did not plant pumpkins this year because it absolutely took over our garden beds last year. But I guess God had other plans for the garden this year as I have a great amount of pumpkins that grew. I think it fascinating that they are hanging from my tomato cages and green bean tunnel.

winter 003While working around the homestead today, I had an engineer here all morning checking, measuring, taking pictures and asking questions, readying our house for a solar panel installation. We are really looking forward to adding solar to our property, hopefully to help get our utility costs reduced and be more in line with our belief in sustainability and eco-friendly.

I think this is the first time I have ever written over 1000 words for one post. I hope I did not bore you, but there is always a lot going on at the little suburban homestead this time of year. This hero, although tired, really enjoys the activity.

  • Receive tracking logs for maintenance and monitoring of your system

We will also be covering topics about: cycling your tanks, grow media, heating, lighting and covering any questions that you may have leading a good understanding of aquaponics and how to start.  After attending the basics class, you will have the knowledge to successfully start your aquaponics adventure.

Once completed in the greenhouse, you will roll your sleeves up to be  completing your own IBC tote tank system. Be sure to bring your truck or trailer. We sold almost 100 of these last year at $299 each and you will take yours home with you the day of class!

I will take you through step-by-step in building your tank and the importance of measurements, heights, and clearances to insure your tank will function properly. Although we will have the majority of the parts pre-cut, please have knowledge of basic hand tools and drills. If you have a battery operated drill, feel free to bring it.

With any system there is some basic maintenance. As we complete the tank systems, I will cover basic maintenance and common causes of malfunctions,  as well as the necessary steps to solve and prevent future issues.

If you bring pictures of the area where you want to install your tank and a simple drawing , I will help you determine the best setup for positioning lines and filters. We can also make small modifications on the spot that would make your system very user friendly for your location.

Simple drawing example. Can just hand draw layout as well.

Aquaponics Australia and Solar Energy

This is awesome and works well. The only issue is if you grow a fish which must be in an environmentally controlled tank. Growing tilapia I must heat the tanks which takes too much energy to run from a small display of solar panels.

The @#&*+$% Waterfall Pump is Clogged Again!

This spring I finally got around to really cleaning out and around my pond. The weeds throughout the rock beds were getting far too dense and it really looked bad in an otherwise interesting yard.

My pond, unlike many others, has no fish. The pond serves two primary purposes:

1) It is situated just in front of my bee hives, so the bees will have water without invading the neighbor’s pool

2) Grow duckweed to feed my aquaponics fish and my chickens.

If you have a pond, be sure to read my friends article below about an easy inexpensive way to filter better.

 

Mind Your Dirt

It creeps upon me like a slow death, void of meaning or romance. From my bedside I can hear the daily lessening of its once mighty cry as it slowly dies. A single tear forms in the corner of my tired eye as I realize in the dreamy state that something is terribly wrong. The deafening roar of water that once dominated my senses begins to weaken to a soft purr of drip-drop failure.

My failure. My shame.

My waterfall pump.

I curse the pump filter demons that have taken hold of my once amazing water feature! Just look at this pathetic thing; after three solid days of “work” it’s all gummed up.

Where does your lettuce come from?

Great informative article on hydroponic farming. Especially intrigued that production is 20 times that of traditional farming. Aquaponics, I believe, has the same ability, with the addition of being able to farm fish at the same time.

Search for a Greener Life

As sustainability enthusiasts and professionals, we are constantly bombarded with dire statistics and news. Good stories and news are sometimes far apart and well spaced. Therefore it is with a lot of excitement and happiness I share these two excellent pieces on the future of agriculture, our food systems in general and urban agriculture in particular.

The two exemplary farms are Gotham Greens; a hydroponic venture and the other is AeroFarms. The best part about both these farms are they are viable for-profit businesses!

I know a lot more about Gotham Greens as I was lucky enough to visit their Gowanus facility which resides on the top of Whole Foods Market, a US based organic food grocery chain. Also, a few years ago, as part of my Masters of Science Program, we had the founder Viraj Puri come to my University campus and give an introduction to his company.
