Intro: The Amazing Plant (Germination) Collar for Aquaponics and Hydroponics

This is very short and easy project.

While getting the GL Aquaponic Interlocking Raft System (GLAIRS) project off the ground we deceided to experiment with the plant collars.

They are made from closed cell foam with a cross cut into them to insert seedlings for support in the 5 and 7.5cm slatted (net) propagation pots.

Instead of a seedling, we placed lettuce seeds into the collars and placed it directly onto the water in the GLAIRS on a koi pond and to our suprise and delight the seeds germinated.

We tried the experiment using a large tray using bush bean, sweet melon, rocket, lettuce and cauliflower seed and within 4 to 5 days in full sun, the seeds germinated

What have we achieved.

Seed has been germinated, without a germination substrate, directly on the water in the collars. Once the root is long enough the collar and seedling are placed in a propagation pot and the inserted into a raft system or vertical garden systen and allowed to grow either Aquaponically using fish waste (organic) or Hydroponically (not organic).

Kids can try this on their fish tanks at home or on the fish pond or even on the windowsill in a jar of water.

Aquarium Application

You can now grow edible plants from seed, on your fish tank at home, with the growing plants helping to filter the water and supply cover for fry (baby fish) in the roots.

Easy, simple, no mess

    This has got to be the single greatest discovery since I began aquaponics! I thank you from the bottom of my heart!

    Thank you. just a bit of out the box thinking. When we were young we germinated seeds in damp cottonwool. This is just an adaptation of that.

    good idea but you will be limited to what you can grow the roots will rot easily if they are continuously wet for most plants but it should work for leafy plants like lettuce. this is how they conmercially grow aquaponic lettuce using a barge system

    Hi

    I agree with you that the roots will rot if kept in a static system for too long

    The whole idea about the germination of seeds in the collars is that once the root is about an inch long, the seedling is placed in a propagation pot with the collar and placed in the main growing system where there is proper airation and/or water flow.

    We have been successful with beans, sweet melon, cabbage, corn cauliflower and lettuce so far.

    In an aquaponic system the fish will often graze the roots, removing the detritus that gathers on them and the roots which die.
