Aquaponic Fishtank

[Nyboy]

The Petsmart near me is closing, everything in store is discounted. I couldn't pass up a hydroponic fish tank for $10 I actually bought 2. There is a filter and a space for plant with clay pebbles. Fish is suppose to feed the plant, plant suppose to help clean water for fish. I saw some nice begonias at Home depot. @jackb can a plant growing in soil be used for hydroponics or does plant need to be started from seed for hydroponics ? Tank is only 3 1/2 gallons so maybe a betta or guppy.

What you are referring to is actually aquaponics, hydroponic systems do not rely on fish for nutrients. I guess it would depend on what plant you intend to grow. Plants grown hydroponically have different roots than those grown in soil. If you look closely at the roots of hydroponically grown plants you will see many fine hairs coming off the roots, not so with soil grown plants. You would be best starting the seed in something like rockwool or horticubes. If you want to try a plant you should get a seedling and completely clean ALL SOIL from the roots before introducing it into your system. The younger the better... Good luck.

LOL Thanks Jack I was going to plop a begonia in flower in there.

The type and intensity of the lighting are just as, or more, important than the nutrients.

What about using a cutting rather then seedling ?

 

[jackb]

Not a clue, try one.

Any cutting that would root in water should do well in your container. I usually start my cuttings in perlite rather than just water. Remember to use well water rather than city water for both plant and fish.

I picked up 3 guppies last night. I have to go back and buy a small heater for them. Funny tiny heater cost more then tank. I still have not decided on a plant to try. I thought a water iris but think it will get to tall and flop over. Unless anyone knows of a dwarf iris ? Problem is I don't like house plants want something that will flower
