im sure the fruit or watever u grow would be much better than a standard outdoor grow if u had the correct nutrient levels, light timing and im no expert but id say even ph levels would be a bit difrent depending on the plant ur growing?
id say thered be almost as much info out ther for hydro fruit and veg as ther is for hydro marijuana, just a matter of finding it eh lol.

good luck, let us know how u go, coz i was looking at growing a few tropical fruits.
