Far out pinball your fish are getting big , dinner is approaching fast , at what age and size do you harvest them at ?

Most people grow tilapia to plate size. A tilapia can be plate size in about 12 months.
It is time for me to replant the green house and harvest some fish.

The tomato plants are huge 12’ tall and taking over the green house. It is time to start planting lettuce.

Nice , and healthy eating. Great Solar heat house and build / idea.

Im thinking doing this to a attached Solarium , read about using rocks in storage tanks that were air vented to heat and always wanted to try it.

Could use some advice
in a Area with weather similar to say Seattle thinking that running a 35 pint dehumidifier with a drain set on auto packed in with the rocks to prevent mildew and keep the air moving & warmish

It seems to me the Article from yrs ago had two rock storage areas

Do you have any advice is the plan sound or am I overthinking it and the dehumidifier is not really a good way to go ?

Danner MD 12 magnetic drive pump with a 5 year warranty. 5/22/2015 and it was sounding bad today and not pumping.

I have a spare impeller but when the impeller went bad it took out the cover.
I also have a spare pump on hand and I put the one in.
I called Danner pump MFG and they will send me a new cover for free it has a 5-year warranty.
It was no issue with them email receipt and they send me a new cover.

Yikes 4 years and 3 months and under the wire! :)
Sometimes you get lucky!

It would have cost me about $13-$15 shipped for the part.
But it is still nice they covered it and the process was not hard at all.

It is nice to see company stand behind their products.
They did not try to get out of covering it at all.

They said they will ship it tomorrow.

I have been using some of the ceramic bearing 2 or 3 phase brushless pumps with good luck. They are suppose to have a pretty long service life and are efficient.

I buy the 24v rated and run them at 12v

You want to mount them with the shaft at a horizontal orientation for longest life. I blew up an external controller due to an incident of water running backwards in the pump at a high elevation and was able to replace it with an cheap ebay controller very easily.

I know this is an old thread and I am sure this system was built years ago and is working fine now. But I just wanted to throw out there, to anybody reading this recently. Solar powered water pumps have gotten very inexpensive and are now readily available.

We have 12.5 KW solar power.
Everything we have runs off solar power.

We still have never used any city water for this greenhouse.
It exclusively runs off rain water captured off our roof and down spouts.

I bet it's great to have those resources (power, food & etc) during these crazy times.
My healthy Keto diet is a disaster now. My wife and I are not eating like we used too!

We just went for a walk and I started asking my wife to go get the car, after ONE mile. She said, "Right, I'll start running now".
As it has become nowadays, this is No Country for Old Men.

That sounds awesome. I am in the design phase of a new home, which I hope to build next summer. But aquaponics is one of the big must have items for us. When I was younger I used to design and build ponds, in landscapes, that used a lot of the same principles. The big difference being, we used (ornamental) plants to keep the pond water clean, but never harvested them for food. I first learned about aquaponics from a coworker who built a great system a few years ago. I am really looking forward to building my own system. The big downside is, I am sure my wife will name all the fish and any attempt to harvest them for dinner will be met with revolt.
