Not a physicist either but currently self learning quantum physics. Note that Planck length and time are just units - they do not mean that space and time are quantized. Quantum theory treats space and time as continuous variables. While it has been speculated that space and time are quantized I do not believe this has been experimentally verified because the scales involved are beyond current experimental reach.
