How to adjust pH in aquaponics systems

Here is a great video on how to adjust your aquaponic system naturally. I have been scared of the ph, this makes it easy to understand and can be done naturally without chemicals.

Profitable herbs for aquaponics

   Well now your growing some plants and raising fish, but wish that you had enough money to  build and grow more. Obviously we know we can sell off some of our fish and even our lettuce, but everyone grows lettuce and most that have aquaponics have tilapia, check craigs list to see if anyone is selling tilapia, if not jump on it, it can be a gold mine.

  But I want to go over a few herbs that you can grow that you may already be growing or can easily grow that can make a small profit if you can find a buyer.

Cilantro is an excellent source of potassium, is low in calories, and is good for the digestive system. Expect to sell a good portion of this at the Saturday market. a lot of the latin restaurants will buy fresh Cilantro also. These are easy to grow in flood and drain systems and self watering buckets (dutch buckets) systems.

Make up your own salsa and sell that as well.

Basil is my favorite to grow! It is so easy and gives off a great aroma. I use it in everything I cook, and fresh basil makes the best pesto. Besides making every dish just fabulous, it also has great medicinal properties. It helps treat common colds, headaches, stomach disorders, inflammation, heart disease, various forms of poisoning, and malaria.
 Growing Basil is easy in flood and drain and I have good luck with it in rafts also. It supposed to help keep the flys down too, but havent had that kind of luck with it.  Keep fresh plants to harvest.

Oregano has a distinguish flavor that one just has to have if they are cooking Italian food. Fresh Oregano or dred can be sold to health food shops, since it is good for so much healthy properties, including colds and viral infections, digestive upsets, pain relief, and respiratory problems. Warming oregano can also be used to bring on menses and ease painful menstruation, even cancer.
I personally use the oil to keep from getting colds, just add a few drops to an ounce of water and drink, nasty as all get out but works.
It also works in flood and drain systems. I haven't tried it in float systems but would assume that it would do great.

Chives are a steady seller. These will start to germinate after a week or so. And unlike basil, these can actually do quite well in cooler weather.

I like to use chives in place of onion on a regular basis.

Every restaurant will use these if you can give a fair price on them. simple to grow in most mediums, and will multiply without assistance from you. Also puts on a pretty lavender flower.

Chamomile can all be traced to its effects on the nervous system and digestive system, as well as its anti-inflammatory and antibacterial properties. Works great for a sleep aid and even has a lot of uses for skin and hair care. The market for this is easy to get into. Cant find it at the super market and everyone has an illness that this can help. I like it to help sleep, it seems this has been a small problem of mine. Grows in a flood and drain system, but should be given a lot of space.

Parsley is  a great cash crop because it grows so well. It is used in many dishes. Parsley leaves and root are high in iron content and rich in vitamins A, B, C and trace minerals. Parsley adds color and aids digestion of the foods we eat and acts to prevent gas and bloating. Its just an all around good herb. And can be grown in both flood and drain, or raft, or if you choose, it can be grown in a bucket system.

Catnip is great to sell at farmers markets. Most everyone has a cat. You can sell the whole plant, or dried in individual bags. But also have to let your customers know how good it is for them. It is a soothing sedative for humans. It has been known to provide pain and stress relief and to also help with flu and cold symptoms. Catnip leaves contain considerable quantities of vitamins C and E, both excellent antioxidants.  Grow these in a rock or shell medium.  Makes great Christmas gifts and can be sold at craft fairs as well as the weekend market.

Lavender Is usually done on a more commercial basis, but if you have a local florist or someone that makes home remedies using honey and such, this is a popular product. It can be added to tea and has a lot of medicinal gifts. Soaking in a lavender scented bath relaxes away mild depression and anxiety and may even lower high blood pressure and improve circulation. Helps with sleep aid also. Great to grow in an extra bed that has a lot of room, or you can lace these randomly in your other beds.

   When picking out herbs or plants to sell, try to use what people are familiar with. Exotic plants do good if you can find the right market. But some folks like to have what they are used to or what their grandmother used in her kitchen. Start small and investigate what you are growing. Its like Vanilla beans is a great cash crop, but they take so much care and time, that its only worth it if you have a dedicated green house just for that. So keep it simple and get ready to make a lil profit. and live a healthier life for a bonus. 

   If there is a plant that you think is a great profit plant, let me know, and would love to post it.

Raising crayfish in Aquaponics

     My experience with using crawfish (or cray fish depending where your from) has mixed feelings.
Now I dont for some reason have any pictures of my set up but let me explain my pros and cons about raising Crawfish.

I was doing an experimental set up with a flood and drain system with a small deep well attached.

 not wanting to use any fish because of the cooler temps in NW Arkansas that time of year I decided on local creek cawfish. First lets just note that when catching these quick lil buggers it would help if you had a net. But caught about 20 small to medium crawfish and also a few tadpoles (different story) and one of those bottom sucker fish, and also 3 snails.
  
    I placed all in a small styrofoam cooler without a lid and placed them in the back seat of the truck. That was mistake number one, when I got home, half of the crawfish had escaped and were all over the truck. Took about an hour to find them.

   My patio is inclosed with a pool dug into the ground. I built everything the same level an currently pouring concrete around the pool.  Everything is closed in.

    Now to the point. Once placing the crawfish in the aquaponics. I built a wire box from old chicken wire so that they can climb on and also cut some pvc to place on the bottom for privacy.

   The next day, I discovered 2 crawfish in my pool, now remeber it is cool out, so off I go with snorkle gear and catch the 2 and place them back in the 75 gallon tank.
I thought well that was odd couldnt really see how they could climb out.
Next day same thing, but 4 this time. back with the snorkel gear to chase the crawfish down.

    So I watched them for a while noticed that when the water drains from the grow bed and the water table rises that its only 3 inches from the top, so I took out a few gallons until it was 6 inches thinking maybe that would do.

   Next morning nothing was in the pool, I was happy, until the next morning, 3 more were in the pool and was on its way. starting to almost enjoy the cold water swim now, but not quite.

    I realized then that they were climbing up the folded part of the liner. after a month of all this and modifications I gave up and brought them back to the creek, it was time to use my pool and didnt need them in it.

    But to the good part of it all. The natural habitat worked very well. I even dipped up duck weed from a local pond. The water stayed clear and I fed the crawfish fish pellets and they really loved the sweet feed that I still had from when I had a pig. I enjoyed having them and watching the lil habitat work. The plants seem to well too, the basil grew tall and had some cabbage taking off.
I think I would like to do this again but with a tank that has slick sides.
   The nutriets from the habitat looked to be balanced even though I never took any test.

So if you see a few crawfish in the creek and have a container that will hold them, do grab some, very beneficial, But if you have a pool close by and they can escape, well its best to just leave them where they are, lol

Oh! and about the tad poles, well they do grow! and it is so awesome to watch them get their legs and

see them change their heads and then next you see them sitting on the side of the tank and jumping, and then..... well then you see them under your lawn furniture are taking a dip in your pool. So maybe not the best idea, but it was fun.

If you have had any experience of raising craw-fish in aquaponics, please leave a comment, I would like to know how to do it without sharing my swimming pool.

Worms in Aquaponics

When I first heard of putting worms in Aquaponics, I just couln't understand how.

I just assumed that the worms would drown, after all when it rains hard you see worms coming to the surface all the time, so I thought they were drowning, but in fact the water was just pushing the oxygen out of the soil, so the worms had to surface to breath.

As long as you are producing plenty of oxygen whether it be from aeration stones or flooding and draining your beds, then the worms do well. I have even seen worms in the tank, up against an aerator doing well, even very lively.

So now that we can say that worms can survive, why would we even think about putting them in our aquaponic system?

Well there are many reasons, more than I will even list but the basic purposes are as follow:

• They break down solid waste from not only your fish but the decaying plant matter.
  
• Suppress parasites, diseases, and pest including mites, aphids, mealy bugs, and even tomato worms. Basically, keeps your plants healthy.
• Cuts down on how often you have to clean your grow beds.

• Loosens up your grow beds so that the water and nutrients can flow freely to get to all the roots of the plants.

Again, That is just the basics with out getting into the technical mumble jumble.

When deciding to put worms in your system, it is recommended that you  try to buy from a reputably company that sells worms for gardens. Using places like craigs list is ok, but you nver know  what the worms have been growing in, which means you dont know what kind of diseases that may be with them.
If you are using them from your own property say from under stones or where ever you will be harvesting them from, make sure you wash the worms first to get any excess dirt off of them, just in case their is a contaminate on them, not a big deal in my opinion, but it only takes a second to rinse them.

But by adding a few worms here and there to your system, it will give your plants and fish a healthier life.

Bell Siphons

   Well having a nightmare of a time with my first bell siphon, I decided to put together some quick reference to some ideas on Bell Siphons.  The automatic bell siphon is a great thing to do, because it is just automatic without any help from out side power sources. Just uses the suction and gravity from the already falling water. Even if you never use this system as your main system, everyone should try it just to see it work. 
Here is a great reference pdf from Hawaii College.

Construction of Automatic Bell Siphons

for Backyard Aquaponic Systems

 

 

I myself like to keep it simple.  I used a 4 inch pvc with holes drilled in it for a guard and a 2 inch pipe for my suction pipe.

I came up about 1 and a 1/4 from the bottom and drilled 1/4 inch hole in my suction pipe to stop the suction.

Then I used a 3/4 pipe with a 1 inch reducer at the top for my drain stem.





then under my grow bed I just installed a 3/4 pvc with 2- 90 degree elbows

This seemed to work fairly well.

There a lot of ways to do the siphons, but it all depends on your size of grow beds and height. The bigger the grow bed is, the harder it is to either get the siphone to start or in most cases to stop. If this happens you may just have to tweak it some like adding a air hose on the side to help cut off the suction, or even add more holes in your suction pipe. But keep it simple first and then modify as needed.

Where to buy tilapia

   Well when we start off with auaponics its a blast! If your like me, you can't sleep at night with all the ideas in your head of building your own system. Lets face it, after looking at all the videos on You-Tube for an hour or so, we can definitely wipe out the hardware stores with our own ideas.

   And then we go to the local nursery or department store and buy some plants and seeds which gets us off to the right direction but now where do we get the fish?

   Well there is several places but choose wisely. First off I netted up several perch from a near by pond, and I thought that would be perfect, but I was mistaken. Because they were wild they would only eat real food as in worms, tadpoles, or even bread, but no store bought food. I would go out every day and dig worms but after a while that was too much work and less was being found every day, so I took them back to the pond.

I first would suggest to get your fish from a reputably source if possible. This way your guaranteed to get quality fish without the chance of disease.
There is several aquaponics suppliers that either carry the fish of know who to contact.
Aquaponic Store is one of the ones on my list. They have many options to choose from including other fish besides Tilapia.  

  Tilapia Depot from Florida has one of the widest range of fish that I know of.

   But I think first of I would Check Craigs List to see if anyone in your area has the fish you would like to try. chances are there is and you can drive to their place and see how they are doing it. If there isnt
then this would be a great opportunity for you to think of a business venture of selling some fish to help offset some of your cost.

   My last choice but one that I like to use more often is E-bay 
keep and eye on this, because there is always a good deal, even free shipping on some.
If there is not free shipping then try to get someone to go in with you to order your fish. its not the fish that cost so much, its the shipping, you can basically get 15 fish shipped for the same price as 50.

Hope this helps,
Let me know if you need any help, and I'll be glad to assist.
