Are you interested in growing commercially? Do you already grow commercially? This is the place for exchanging ideas and experiences, and making new contacts in commercial aquaponic agriculture
You might also consider joining the Commercial Aquaponics discussion group for lots more information and discussion
With a 1200 gal tank you can have lots of grow bed space. If you want to go commercial I would recommend that you use the floating raft system. There are MANY advantages over gravel beds. Most gravel beds can easily be converted to rafts. As far as bugs go, you can use woven row covers supported by PVC. This can save the huge expense of building greenhouses. The woven cover allows 90% light and 75% air transmission depending on the brand. You can see an example in my photos. Also check out Friendlyaquaponics.com

Very Interesting topic for those serious in undertaking Commercial AP projects: "Symbioponics". FA does advocate use of similar method re low density fish stocking but this is far more detailed...check it out for yourself :-)
Ok so it looks like they have trade marked a term which basically means, keeping the system in balance. Don't be fooled into thinking that they are doing something new or unique, it is just marketing what everyone involved in Aquaponics is trying to do, balance a system.

Question : Why are media based grow beds not used for commercial systems?
Carl Smith said:Question : Why are media based grow beds not used for commercial systems?
I think there may be a few small semi commercial media based systems but I think the primary reasons are,
1-UVI has done most of their research using rafts and that is what many commercial systems are based on.
2-cost, truck loads of media gets $$ and it's heavy with makes it $$ to deliver it.
3-Media beds don't lend as well to conveyor belt sort of production of plants the way rafts do. Nor does media really allow one to easily keep plants packed closely together while they are small and then space them out more as they grow to use the growing space most efficiently while rafts and NFT work a bit better for those methods.
Media beds are very well suited to a backyard intensive gardening system but not so well to something that is trying to churn out huge numbers of plants that are all the same. Raft systems are best suited to a situation where there will be attendance daily to check the plants and deal with any problems quickly and daily water testing while a gravel bed is a bit better able to cope on it's own for a few days without being checked on. They are really just different methods, each with their own strong points and weak points.
There is of course the new vertical media system of Nate's that may be very good for commercial operation but it is kinda different than all the others though it has some similarities with a few.
