Is this Design for Ebb and Flow Ok... Will it work?

I have a designed system that I created by reading lots of posts.
Please let me know if you think it will work OK, or let me know the
problems it may create.

Here is my ebb and flow system:
It is a 2x4 table on which I plan to grow 14 plants in 4inch Rockwool cubes
sitting on a coco mat.

My reservoir is 20 to 25 gallons, and I plan to flood 4 or 5
times a day for 30 minutes.
Nuts will be GH MaxiGrow and Bloom which I have used in the past.

Pump and system has been tested and seems to work fine.

I'd appreciate any ideas or criticism you have.

Pictures will help get opinions on this. A custom system is hard to give an opinion on without pics.

Here is a link to my Ebb and Flow/Food and Drain system I built. This might be of some help.

I think that 14 plants in 4" blocks is a lot. If you feel that you need to do that many , do them short. They will crowd each other. Less plants will produce more. Also, three feedings a day is plenty. They need to drain so as to draw in oxygen.
