Hi everyone! I had some issues with setting up a grow bed's plumbing and it got me to thinking, in the interim, can I just set up a raft directly onto the fish tank? If it were any other kind of…Continue

Does anyone know where to get the blue board at a good price? Has anyone used any other kind of board?

Hello Nigel & Christian,
I totally agree that $2.28 for a 4'x8' 2inch Dow Blue Board sheet is a "dream" price...I would like to buy a lot of them at that price. I believe that this was just a "typo" and the actual price is closer to $41.28.
Still, if I can buy them for $2.28 per sheet, please let me know ASAP :-)
God bless

Dave, can you put up a number, email address or url for Gator? I keep finding one in Clearwater and I'm not sure if its the same company. I'm based in the Caribbean and that's the best price I've seen on the Blue board in a long time.

Dave just got off the phone with Gator and their price per sheet is $41.28. How in the world did you get it for $2.28?

Nigel, thanks for the info and the pictures. Glad to know that someone else has done it and it's working.

Dave thanks for your input brother. I tried looking up Gator Gypsum but their website is just a blank page. I'm going to call them in a few. How do you like their blue board? Do find it to be sturdy and possibly long lasting?

Christian, regarding the spacing, I've experimented a little with it and what I've done is have them really tightly spaced in the early stages of growth so I would have a 2'x4' raft with something like 50+ holes then I would move them to a raft with anywhere between 28 - 32 holes.
Then I would place them on one with less holes:

Robert, to aerate your plant roots, part of your setup should be the inclusion of 1-1/2" by 0.75", 0.35 cfm airstones in your troughs. Dependent on the size of trough you're using. A 4'x8' trough would normally have one airstone which would be of course driven by an airpump. Thus your roots remain in the water. Hope this helps.

I am just starting using rafts. Was wondering how the roots
get oxygen if they are in the water all the time. Do you need to position the baskets so that some of the root system is out of the water to get oxygen?

On blue board. I recently purchased 12 sheets of 4ft x 8ft 2inch thick blue board from Gator Gypsum, in Largo, FL. I am 45 minutes away so i picked them up in my Ford F150 pick up truck. Price was $2.28 a sheet plus sales tax. My guess is they will ship it, if requested.
