Soilless Triple Reservoir idea

I have done a few closet grows with my version of the hempy bucket. Note that this is for the lazy/passive closet grower.

Here is my idea to make the grow even more foolproof:

Have three separate reservoirs in the same container. Each reservoir would have it's own plastic fill tube.

Reservoir 1 would have the standard nute & water mix.

Reservoir 2 would have nothing but water.

Reservoir 3 would have double the recommended nutes & water.

(A reservoir could be as simple as a 1 or two liter soad bottle cut to size and placed in a 3 or 5 gallon bucket.)

My theory is that the plant best knows it's own needs and would uptake the maximum amount of nutrients without any chance of nute burn.

Retarded or brilliant?
