Pond liners for grow beds? Good Idea?

    I was looking at polypropylene and polyethylene liners. The polyethylene is reinforced with strands of cloth like material, I think it is also polyethylene as well. I also saw some pure rubber "BUTYL" and called for info as to these items being food safe. Sales guy says that they were fish food safe meaning you can eat the fish grown in these ponds safely.
    Any ideas about that? I am getting ready for new GB's and am thinking how much easier it will be to make the beds out of wood and just lay the liners in and fold them over the edges. They are UV safe 90% strength at four years.
    Sounds great as they are cheap. a ten by ten foot piece is 75.00.
    Any ideas? This looks to be easier and less expensive and faster than building and then glassing...

    Hi Matt,
    The one I have seen that is avbl in the US is "Dura-Skrim® Reinforced Polyethylene Film".
    It is an excellent product having a reinforcing mesh through it and is white in colour not that that matters much.
    Google "Dura-Skrim 20WW liner" for a supplier near you or that will ship to you.

    Trying to find it here in Aussie but cannot locate it......drat.

    Dura-Skrim 20WW liner

    Thanks again Murray. I have been searching the net for a local IBC supplier here in socal, but Drat! they all carry only reconditioned units costing 300.00 each. Too much$ for me. So I think I will have to go with pond liner for FT and barrels for GB's. One supplier recommended barrels for everything because we are earthquake country. I duhno but does make some sense. I wish I could find IBC totes that are 50.00 and food grade but just can't.
    Any suggestions as to a system utilizing plastic barrels and pond liner? I don't want to re-invent the wheel.

    Blue barrels are good and have been used by loads of people. Have you looked into Barrelponics by Travis Hughey ?

    GPS Global Plastic Sheeting... I get my Duraskrim through them. Free shipping and it always arrives within days. I make all my grow beds and fish tanks using this stuff. For under three hundred you can get a roll 6x100 that is a lot of tanks and grow beds. They have smaller rolls as well. Cheapest supplier I found.

    Jason... How old are your grow beds? Have you had any issues with the plastic sheeting deteriorating, cracking, and/or leaking? That's my main concern with using sheeting, but I am needing to expand. Certainly like the idea of minimizing costs. How many mils thickness are you using?

    I have had mine for quite a long time without any issues. This product is uv resistant and claims to have a very long outdoor life. It is 20 mil, very tough stuff. Quite impressive really that it does not tear when filling with gravel.

    Just building another large media bed and several more rafts using this.

    for sourcing your ibc's look for a local tyson proessing plant, and any tote containing the eliminate product(food grade vinegar substitute) if they won't sell them to you directly they usually can tell you who they sell to mostly feed stores etc, i get mine here @ 50 a pice 40 if i buy ten or more also they usually have food grade barrels that mostly contain liquid smoke extracts etc.

    Jason, just curious how do you measure the amount of liner needed. Most websites I've found so far recommended an amount that makes absolutely no sense to me. (for example: they are recommending a 10x10 feet liner for a 5Lx3Wx1H grow bed).

    To determine the liner size just add the width plus both sides....and then add the length plus both ends. for example I always make my beds 3.5 ft wide this allows me to use the standard 6' plastic width to cover the 3.5ft bottom, 1 ft per side and gives me just a bit extra to roll over the edges to protect the wood. You can buy any size but the six ft wide roll is the cheapest for some reason.
