Aquaponics Home System – Part 12: Plant Tank Liner

This is truly an Ultimate Aquaponics Home System I’m building, like the title of the guide says, right on the dinner table 😉 :

This the MDF box being prepared with pond liner to hold water and function as plant tank in the aquaponic system. The thickness of the liner is 0.5 mm.

In order to keep the liner in place before it can be secured I’m using three planks resting on the bottom to make sure the liner is pressed up against the side walls. It would actually be better to use one large board that would cover the entire bottom of the tank, but this will do.

Once the liner goes up over the edges it’s held in place with rubber coated clothespins.

Now I need to come up with a way to fasten the liner for good (duct tape?…), and a way to fold the liner in the corners so that the plant tank will still hold 20 cm (8″) of water.

    Boy does that look familiar. I just lined my growbed and it’s about the same size.

    Personally, I didn’t worry much about fastening the liner. I folded the corners like a christmas present and used a staple gun to tack those down, then filled the bed with media. That holds everything down very thoroughly.

    I’ve got some pics on my blog if you’re curious:

    Have a good one!

    @Friday: Very impressive work! 😀
    I’m planning on letting my plants grow in netted pots. Is it better to use clay pellets?
    I’ve read that plants in an aquaponics system grow up to 8 times faster compared to garden soil – is that really true?
