<p>Green Acre Aquaponics used to sell 2" blueboard already cut to 2' by 4' pieces. You might contact them to see if they still carry it. I know the 2" blueboard is usually a special order item through lowes or home depot.</p>

<p>When in doubt, go with the DOW BlueBoard, as they don’t use the troublesome hexabromocyclododecane (unlike Owen Corning or Insulfoam and some others). </p> Hi John:

<p>Hi John:</p>

<p>The foam will work for rafts, you're gonna want 2" think as the plants get too heavy before harvest.</p>
<p></p>
<p>As far as the raft beds go the biggest thing working against you is simply the weight of water. Water weighs 8.3 pounds per gallon; a 50 gal aquarium weighs over 400 pounds (50*8=400) That is one of the reasons round tanks are so prevalent, the opposite sides work against each other forcing the other side to stand up ...</p>

<p>Okay, no cattle panels.</p>

<p>Ok, I know I don't have any rafts but the bed construction is the same as I would do for a raft.</p>

<p>John, I just sent you a private message with info on the liner if you are wanting to get a small quantity there are at least two sellers in Florida that will cut it for you.</p>

<p>As to the cattle panels for sides to a rectangular tank. No I don't recommend it. I did once try to make a "raft tank" out of cattle panels and liner. didn't work very well.

Even after I pounded in steel fence posts every 4 feet and added wires across the top to hold the sides in from blowing out, I still wasn't terribly happy with it.</p>

<p>I was thinking of cutting the panels down to 16" and adding steel posts on the outside for added stability. It would be built on the ground, so it really isn't that tall. I saw the pics you posted of the taller, maybe 4' tall, round panel structure and I can see where that might of been less stable.</p>
<p>I appreciate the invite for a show and tell. Perhaps some time in the near future we will take you up on that.</p>
