AQUAPONICS UPDATE #6

August 9, 2015 darling downs 10 Comments

Our aquaponics system has been up and running for about 9 months now and it continues to improve. The fish are getting bigger so the manure output is enlarging, which then makes the vegetables grow better and quicker.

Our broccoli seedlings are booming ahead and the picture below shows them in early June.

Below is a picture of them now so you can see how they have grown and there are heaps of them.
We actually have one head forming already.The cauliflower seedlings haven’t been as prolific in germination or growth, but they do take longer to get to harvest than broccoli seedlings. These are still going well though.The silverbeet seedlings continue to produce and I pick the leaves off these at least weekly and they continue to thrive.

The pat choi seedlings are growing well, although there is some yellowing of the leaves. This maybe shows they are getting quite enough nutrients at the moment.Our tomato seedling is still growing and is now flowering, although some of the bottom leaves are dying off. Hopefully it will continue to thrive as the fish grow bigger and we can harvest some lovely ripe tomatoes. This coming season we will grow our bulk tomatoes in a hot house in the dirt but we hope to grow our heirloom ones in the aquaponic system.Our english spinach continues to grow although it is very slow. I suppose this is better than it not growing at all. These seedlings look really healthy too. I grew some celery from the bottom of one in a bowl of water until it had some shoots on top and then I planted it in the gravel. It has really taken off and I have another one on my window sill that I will plant this coming weekend. I usually just pick off the stalks I want to use and I never harvest a whole plant, this keeps the whole system working better.I sprinkled some carrot seed over half a bed and it is coming up well, it will be interesting to see how this goes.
If you look closely you can see the fish at the bottom of the tank.The sweet potatoes didn’t work and I did a bit more reading up about them and it says that they don’t like a lot of water, so that is probably why they aren’t growing properly. We will put some in straw beds either in this hothouse or the other one in a month or so.

Okay that’s it for our update now, I will keep you posted.

Blessings to you all.

AQUAPONICS UPDATE #5

Just a quick update to keep you all informed because I am sure that you are just hanging out to know what is happening :-).

Everything is growing really well, I think we have seen a transition from struggling to succeeding. This means that the fish are growing and their output is increasing.

Below are the broccoli seedlings.

The tomato seedlings that were surviving are now booming ahead and there are three of them.

We continue to pick off the green spinach and it just keeps coming back. The picking seems to be doing it good.The Patchoi seedlings are really starting to take shape and it won’t be long and we will be picking and enjoying them also.

We picked our first beetroot from the system and it looks just great.

Friends of ours bought a banana plant and when we saw it we thought it was such a great idea. We didn’t think bananas grew this far south. Our friends ordered us a couple and we have put them into pots in the hothouse next to the aquaponics system.

So hopefully they will grow nice big juicy bananas.

I will keep you updated.

Blessings

AQUAPONICS UPDATE #4

May 20, 2015 darling downs 14 Comments

We are fast approaching winter and the weather has been damp and cold, but it is nice in the hot house where we have the aquaponics.

The sweet potatoes are going okay with the first ones better than the last ones. We did have some die off so I have planted some more shoots and I also planted a whole sweet potato with shoots on it. I am looking forward to seeing how they go. The potato I planted with the shoots hasn’t died back at all.

This is English spinach I think (I didn’t keep the packet – slack I know) and I pick off this about twice a week and it keeps coming back. It is very tasty sauteed with garlic and butter.We have planted some broccoli and cauliflower seeds and below is the broccoli. I planted over half a bed and the good thing about broccoli is that it grows side shoots, so once you’ve picked the main head you get the benefit of those extra bits. That is why I planted more of these than the cauliflower.
With aquaponics you can’t harvest everything at the same time, you need to stagger harvesting and planting, otherwise it mucks the system up.

The tomato seeds that I planted weeks ago are still coming up. Some came up and died off but there are about 3 decent looking plants. Here is one below.

I have also planted some more spinach seeds and pat choi seeds in the same bed.

Below are the original capsicum plants that we put in last November. The leaves all drop off and then new shoots appear and then they flower. We haven’t actually gotten any fruit off them but we are still holding out. The original tomatoes have finally died off and we might actually close this bed until we can get some more fish.
We still have fish in this milk vat and they are growing well, I still can’t get a decent photo, but this shows the water flowing and the air hose making bubbles Air into the fish tanks is so important, without this air the fish die.No 2 daughter picked the last of our tomatoes and we have laid them on newspaper on top of the sump tank. I have left some red ones amongst them in the hope that they ripen. I go out each day or so and pick out the majority of the red ones and bring them inside to eat.
Well that is the latest on our aquaponics, we now have power installed properly and have decent lights so we can work in there at night.

We are working on getting some more fish, we need at least 100 more and at the moment my husband is thinking of sourcing trout.

Blessings

AQUAPONICS UPDATE #3

April 22, 2015 darling downs 10 Comments

The plastic is finally on the hothouse and it is getting to be a nice warm environment in there, which should be good for the fish.

When our son-in-law was down over the Easter period they got into it and put it on. It took the three of them to do it, and the help was much appreciated.
Can you see the rectangle behind my husband? This will eventually be a window that we can open in the summer so that it won’t get too hot and I will be able to step into it without my glasses fogging up all the time :-).

Below is the entry to the hothouse. We have butted it against the back wall of our workshop which has a verandah on it. This has given us a nice dry entry and a beautiful yellow rose on the edge.

We have had some pump issues and are trying to get a replacement on the more dearer one that we bought, so hopefully that will be sorted.

We have moved the little fish into a bigger tank and if we counted right we hadn’t lost too many.

Now onto some of the vegetables.

Below are the sweet potato shoots that we grew off our sweet potatoes. I think there is about 13 or 14 or them. If you want to see how we did that go here.

Here they are planted. They look really good.

The lettuces are still going well but growing slowly. They haven’t died off at all and look good.

The beetroot is going great guns and I hope that the growth beneath looks as good as the growth on top.

The silverbeet is going well too and I am going to thin them out shortly.

Our tomatoes that we planted have come and gone and come again. One has a tomato on it and the other is dying off. They have been doing this often, so hopefully it will come back again.

Overall it is going well. It will be good to see how it goes now with the plastic on and the fish growing bigger – and producing more manure. They say it can take 12 months to really get the system working properly.

There is a lot of trial and error involved in this operation and we are learning quite a lot as we go.

Another update shortly….

AQUAPONICS UPDATE #2

February 15, 2015 darling downs 8 Comments

Well it’s time for another Aquaponics Update and I have been busy taking photos.

The system seems to be working better now and our little fish are growing well, although it is hard to get photos of them (sorry).

OUR BIG BIG NEWS IS…. OUR YABBIES HAVE HAD BABIES

BEFORE

AFTER

If you look really closely you can see the babies, there were some in the bottom of their tank but they are so small. If you are interested in more information about yabbies click here.

Below is a photo of some of the lettuces and they are growing and staying healthy. The drum with the small fish in them is feeding directly into this bed which might explain why they look so good.

Here is a beetroot plant, you can just see the new green leaf just beginning to grow at the bottom.

We already have about 10 larger fish that friends caught for us and you can see their outlines below. I am sorry the photo isn’t really great as it’s hard to see them.

In our sump tank we have some yabbies and an eel. The eel normally lives in the pipe but you can see his tail sticking out near the brick.

Here is a close up of the yabbies in with the eel.

We planted some larger tomato plants when we first started and they have just been hanging on. Now the tops have died off but we noticed a new shoot on this one.

This is the Seasol product that we add to the beds, it is a seaweed based mineral and is meant to help until the fish manure output increases. My husband isn’t sure whether it works or not.

Here is my eggplant bravely stuggling on, it is flowering now, but it hasn’t grown much.

The latest addition has been to sow seeds straight into the beds. Below are some squash seeds that have come up and they seem to be growing well.

Here is another one, I think this is a cucumber. It is fascinating to watch the seeds come up and I find this quite amazing and very exciting.

I have just finished sewing two beds with more seeds. I put in a variety of tomatoes, cucumbers, rocket, dwarf beans, coriander, silverbeet and capsicum. I am looking forward to seeing how many actually come up and then how many keep growing.

Well that’s about it for this post and I will do another update when the seedlings start coming up.

Blessings!!

MY SWEET POTATO

February 14, 2015 darling downs 24 Comments

After seeing a youtube video about sprouting sweet potatoes we have had four of them sitting on our window sill.

It isn’t warm enough where we live to grow sweet potatoes outside, but we have decided to give them a go in the aquaponics system because it will be under hot house plastic in a month or so and hence being grown in a warmer environment.

Below is a photo of them in my preserving jars on our kitchen window sill. They have been there since before Christmas and are now sprouting really well. They have 3 toothpicks in each one which suspends them in the jar.

Gentle Joy Homemaker did hers a bit differently but when we did them like this they went rotten, but I am going to try them again this way. Pop over and have a look here at how she does it.

Here is the most productive sweet potato on the window sill (my favourite). The shoots that have come from under the water level have already grown roots and I am going to break them off and plant them in the aquaponic beds.

You can see the roots in the photo below.

I broke them off and kept the roots intact.

They are now planted in the grow beds and I planted them quite deeply.
I am going to break off the shoots that aren’t below water and place them in a jar of water to develop roots and then plant them out.

I don’t have enough words to explain how excited we are with this. It has been a great, successful experiment.

I have become quite attached to my little potatoes too.

AQUAPONICS UPDATE #1

January 15, 2015 darling downs 6 Comments

Our aquaponics system has been up and running for about 2 months now and things are going good, and not so good.

The fish are going really well and the new ones arrived with no problems and are settling in well and seem to be growing. We have placed them into a smaller drum so as to not loose them in the big system. We lost a couple after they went up the outlet pipes and came out onto the garden beds, but that problem has been rectified and they are going well.

You can see the shadow of the fish in the bottom of the drum. There are a couple of yabbies in their as well.

Here is one of the Silver Perch fish in the net.

Below is a picture of one of our tomato plants that is going well. It has one tomato on it and it is growing but the plant doesn’t seem to have grown too much in the last month. It seems to be putting all of its energy into the growth of the fruit.

The capsicum plants have capsicums on them but the plants are struggling at the moment. We have had a couple of 40 degrees celcius days here and it has been very windy. They seem to be dropping their bottom leaves but the actual fruit is still growing.

We have been told that the system takes about 4 months to really get up and running. The fish have to get bigger so their manure out put is bigger and this will help the vegetables grow better.

Our strawberry plants are struggling also, a lot of the green growth has died off but there are still green shoots so we are hoping that they continue to struggle on and then start growing some more.

We planted a heap of cucumbers but all but one of them has died. This is somewhat disappointing but we have to remind ourselves that it is early days yet and the system is still getting going.

We have some yabbies in the tanks as well and we enjoyed a feed of them at Christmas time. Our neighbour generously let us catch yabbies from his dam to put in our system. We still have quite a few yabbies in the tanks and they are growing well.

My husband just found some with eggs, so they are breeding and this is exciting. He has moved the yabbies with eggs to a separate container so we can keep an eye on how it goes.

IMG_0811[1] — Here are the eggs under the tail of the yabby.

We also found a local eel farmer and he gave us some eels to put in as well. We have one left and also enjoyed a meal of smoked eel over New Years. My husband smoked them for 10 hours in his hot smoker.

When we plant vegetable seedlings in the system we need to wash any dirt off the roots and then plant them. We can’t have dirt going through the system.

Some lettuce plants planted over a week ago.

We hope to go to our local nursery and get some more overgrown vegetables that they can’t sell. These seem to do well in the system because they are bigger and have a few more reserves.

We will cover the area and turn it into a hot house in a month or so when the summer heat is over and Autumn kicks in.

Stay tuned for the next update where I will hopefully be able to show you how everything is starting to grow better.

AQUAPONICS HERE WE GO….

November 28, 2014 darling downs 8 Comments

Well it’s finally happening, the aquaponics system is up and running. My husband and father-in-law have been working hard this week, to get it ready as the fish will be here by the end of next week.

We already have a few fish in the tank and we have started planting a few vegetables and strawberries to see how everything goes.

Now is the trouble shooting stage, waiting to see what goes wrong so it can be fixed before we really get going with it.

We have had a few problems, like the stainless steel vat we had for fish had cracks in it. We had to replace it with a plastic pod.

This is the good vat that we have left, the other one had cracks in it.

We had a couple of these vats but now only have the one left, with some fish in it, and the pods below (covered with builders wall insulation paper) is for the fish coming next week.

Here is the layout of the system. The tanks on the right are for the fish with the grow beds on the left. The lower pod on the left is the sump tank that catches all the water that is cycling through the beds. That is where the pump is situated and the pump then pumps the water back into the fish tanks. This water has then been filtered through the gravel as well as the roots of the plants and is getting returned back to the fish tanks with the manures taken out. The fish tanks also have bubblers in them to oxygenate the water.

Here is the grow bed where we placed 3 mature tomato plants, 4 capsicums and 1 eggplant.

Here is the strawberry bed. You can see in the photo that the grow beds are filled with 25 mm screened scoria sourced from our local quarry. The area in which we live is very volcanic and the local mountains are extinct volcanoes and are surrounded by massive lava flows and the local quarry is on the side of these extinct volcanoes.

You can also see in the photo the pipe running across the top of the bed. In this pipe is a tap which allows you to vary the flow of water into the bed. This water comes from the base of the fish tank where the waste from the fish collects, this waste then feeds the plant roots.

At the end of this area against the wall we will eventually have strawberry beds built. Not sure yet whether they will be vertical or horizontal or a bit of both.

In the photo you can just see the frames that hoop over the top of the area. As summer ends we will put hot house plastic film over these hoops and turn the area into a hot house.

If you are interested in aquaponics just go to you tube to find out heaps more information.

I am looking forward to sharing more of this with you as it gets bigger and better.

The writer of this post (me) would like to thank her husband for his technical contribution.
