Backyard Aquaponics
A place to discuss aquaponics

I had a few unexplained deaths a while back, before it got so cool, but never did discover any likely causes.

Your big one didn't suffer the same fate as my beast from the bung hole, did it?

Very cold here painful to put your hand in he water.

The 24 hour average temp to 9am (mean of the temp every minute) was 3.4C after a min of -0.9C at 6am, I measured the FT water to be 7.0C at 8:50am, after the sun had been up for an hour and a half with a few clouds, so not much warming. This shows how well the thermal ground coupling of the FT and ST works, if they had been in the open air instead of buried, the water would be much colder. I'm only pumping water 5 or 10 mins in the hour overnight at the moment, the air pump stays on full time.

I made a big batch of soup with this freshly picked celery last night, and there is a lot more like that to pick

I'll make more over the next few weeks and freeze it for later, and I'll be germinating some seeds from the last crop and get them planted soon too.
The celery is delicious eaten raw, and it isn't quite as salty as the last crop, which was picked with salinity aroud 1115ppm vs the current 675ppm.

That is good looking home produce, Guna. You must be doing a lot right, so well done.

Man, I thought that the salt was parts per thousand before I realized you did per million. They would have been some *really* salty celery.

Thanks PLJ, celery is a great veg to grow in AP, both of my crops have been very successful.

Ron, yea, that much in ppt would rather limit my options for plant growing

Some pics of the GBs taken this morning:

Mostly cauliflower in GB #4:




and hidden up the other end of GB #4, I grab some leaves to eat every time I walk past:




Broccoli and celery in GB #8, the broccoli is a bit shaded by the celery at this time of year, but I'll be harvesting it soon:

Here are a couple more GBs, #6 with a mix:




and a mass of spring onions and parsley in GB #7, with silverbeet at the other end:

Impressive! Are these fuel by the cod? I thought they were still quite small?

Yea, the Murray Cod are only up to about 10 or 12cm, and not eating much, certainly not enough to support all that growth, which is why I'm adding B&B + Seasol.

Beautiful veggies :-)

Gordon... is there any basis for how and when you apply B&B and Worm Juice... and
Are there any precautions needed to protect fish health.. eg any pathogens in either material..
( Not sure if the topic is discussed elsewhere...)

I apply the B&B during periods of low fish feed demand, such as winter when it is cold, and also for Fe if I think there is a deficiency developing, that seemed to work ok last year. I dont have any particular schedule for it though at the moment, just adding some every week or 2, along with Seasol.
I'm not an expert on pathogens, but have eaten the trout from my system that has had B&B, with no problems. I also used worm juice a couple of times early on when getting the system established, and had no problems with that. I guess it depends on what your worms have been eating, but if they are eating just vegetable scraps, I don't see any difference, pathogen wise, between adding that worm juice and having worms in your GBs.
I know some argue that you have to brew up a special worm tea, not add the juice from the worm farm directly.

.thanks.for that detail... for the record.. where do additives go.. IN the GB's or the sump..
I hope... to keep all sediment from the GBs.. I've. Seen the crap in a working GB that is fed unfilteted...
i wish to catch all solids in filters and have them digested there..

I understand the comment on pathogens from worm juice as compared to from live worms... but
I kinda thought there would be no or minimal worms in a flood and drain GB.. (Except for drowned ones)..
I have a lot to learn..

Anyway... most impressed and envious of your system GG..
