Mine is only 8" deep and they work great for salad greens, basil, sage, bok choi, etc. Used 1" foam (home depot under $4) that is 2x4' peel the anti watever coating off the waterside. old foam from shipping stuff cut into 1x2" peices put the baby start in the foam fold over and stuff in the hole in the foam. It is way cheaper than net pots. I used a sodering iron to make the holes in the foam (outside in ther wind it stinks). Good Luck.

<p>6" deep trays can work but yes you will be limited in your filtration. I would suggest that the 6" deep beds would probably be easier to flood and drain by timer since I've found the shallower beds to be challenging to get a siphon working well in them.</p>

<p>Use what you have for now, I expect you will be planning ways to expand in the future. For this first system, you will want to keep your fish stocking minimal anyway so you can probably go ahead and use the 6" trays. …</p>

For this first system, you will want to keep your fish stocking minimal anyway so you can probably go ahead and use the 6" trays. Aquaponics is addictive and most people are already designing their future systems even before their first system is fully cycled up.</p>

<p>I would tell some one not to buy the shallow tray if they were shopping for aquaponics but seeing as you already own it, I would say use it. At a later date you might convert them over for growing something like water chestnuts or water cress or something.</p>

6" depth is fine for lettuces and herbs. I have several 6" and 4", 4' x 2' hydro trays and they work great. As for depth vs more fish, you would have more biofiltration with the deeper bed so, yes you could convert more ammonia to nitrate. You would still need to monitor nitrates though if you are going with a heavy fish load vs plants as you may need to perform a water change every now and then to keep the levels within acceptable parameters.
