I know that they grow then in towers or in NFT tray, I suppose that flood and drain growbebs could be fine as long as you put only strawberrys in them, because they will grow like mad and send shoots all over the potential room they can get.
I've just had an idea: maybe you could do a venturi system on the water going to the growbeds that could be pumping the fruit solution like a dosing pump, the diameter of the pipe sucking the fruit solution would then be the dosing unit. We have a system like that at my work to dose the desinfectant in the water to clean the fish conditionning area and gear.
My theory of aquaponics is that fish act like a permanent dosing pump that automatically adapt to the environment conditions (less when cold, more with heat and sun). The thing is that it works better than hydroponics because there's no nutrient spikes so no stress for the plants, so no energy consumed to adapt to the situation( for stopping growing and starting the growth). So a dosing system would work the best for the hole system. Sorry I did a very long sentence here, but what do you think of it?
I think that they are quite easy to do so just try what you want to play with, like you'll be happy and your controller too.
