How To Build A Hydroponic System

Can I replace the floor of the perlite if I'm doing an experiment with hydroponics?

It's a science experiment, and I will not buy a system. Research in hydroponics, they say all these complicated things that is hard to understand if I am doing an experiment in which I can grow the plant. Please help, Thanks, Mahalo much. I'm using perlite, but I can only but perlite, seed, and then the nutrient solution and then. I'll make a cup pots with perlite, the seed, and add nutrient solutions. I'm not using a system.

NO. the soil is eroding at once in a whirlpool. You must use perlite or vermiculite.
