Aquaponic Expermint Test 1

may25.jpg may252.jpg thats as much of the roots as i could fit in the pic, goes about another 12" past just not as thick. some issue i think iron and something else, i think from the high ph. And Im starting to think the high ph 7.8-8 is from my source water having to much calcium carbonates, i have to adjust the ph daily to keep it under 7. So a couple things i may try: ro all the water that goes in the system, or hydrochloric acid which would eat up the carbonates and chloride. maybe both. Very good learning experiment, already designing the new system which will have a growbed with worms instead of dwc.
 
Check to see what pH your fish prefer and stick to that. I hear of consistent good results with pH in the 7.5 range with aquaponics.
 
I did research on this, and it doesn't do well when flowering. Adding P and K to the water to flower kills the fish. Saw a commercial operation on line, and they grew leafy vegetables. Not flowering types as they did not prosper. Good luck, hope it works for you.
 
Awesome bro. I like where this is going.


AP DWC is awesome for edible greens!

For buds, i actually ran a super soil and added worms to the actual soil. After its been innoculated i put a 6" layer of sand in the bottom of my beds to filter to runoff that feeds back into my tank. I also mix a lot of perlite as im running a drip most of the plants life. Toward the end of the flower cycle you can use your tank water to fill a reservoir. Used panty hose filled with raw material, a good gpm pump, and air stones to make my flower tea. Then i unhooked my drain line and just do drain to waste the last half of flower :)

With the worms in the soil and doing a bit of top dressing, that inocculated soil will stay good and healthy for a long time and the results are actually quite suitable. :)

I used Tapia and they seem to do well.


This is really cool, nice work
 
Yo sorry for coming in late!

Theres a member on this RIU that is giving away free sample of a rock dust thats supose to be safe for aquaponics, pm me and ill shoot u his name
 
correct me if i'm wrong, but i believe that plecostamus are vegetarians, i use to feed mine zucchini, so does he nibble on your roots?

They're big on algae, I wouldn't know for sure about roots but I haven't seen them go after tank plants. But then, I haven't owned one and watched it long term, either.
 
I've always wanted make an ecosystem. Been hearing about aquaponics for some time now. Along for the ride.

odanksta, thats what im talking about. id love to see a pic of the setup!

I would love too, but i can't because of legal issues, I'm in a non-med state.
One of my concerns with the system is that you can not control the P or the K. I have problems with my lettuce bolting on me. I still waiting on the fish to get bigger..

I think the best way to do this at home would be to have a the fish separately and use the water for teas and add what you need to dial in what your plants need. In aquaponics i think people are to scared to add anything because it might harm the fish. My biggest concern is having to do a 500 gallon rez change with RO water.

Do you have to do Rez changes with aquaponics? I though they were a self contained unit once they are dialed in.

No you don't, unless you fuck up real bad. What i was saying is there are a couple of defferent nutes i would be willing to add to the system. I am just scared i would have to change the rez. The fish are a lot tougher then people give them credit for. I have lost a couple gold fish but haven't lost any channel cats yet.
 
I really want to set one up but I definetly do not have room for it. What kind of fish do people put in there. I wouldn't want to eat gold fish.

Talapia? Yellow Tail? (Mmmmm Yellow tail is damn good)

Tilapia, bass, perch, oscars, a large variety of carp and catfish... and many more. Then there are cold water varieties- but they don't grow as fast and in some climates you'd need to chill their water for at least a few months a year.

Draw back on Aquaponics is higher P& K kills the fish. Commercial Aquaponics grow leafy vegetables, not flowering ones. Another crop in commercial Aquaponics is the fish. Place I saw grew Talapia in large above ground pools. Piped the water to the plants area. They sold the veggies as certified organic. But no flowering veggies were viable. Good luck on your tries.
