This is great! Thanks for sharing! No idea what this hydro thing you mention is, though... And it has a water level indicator? Looking forward to the guide you mention!

Instead of soil (decomposing organic stuff), you use expanded clay balls, pumice, lava rock, or whatever inorganic porous material you prefer. I like LECA by far the most.
The medium is fully inert and can be heat sterilized and reused again indefinitely.
The inner pot is standing a few centimetres deep in nutrient solution (water with fertiliser), with a floating indicator that tells you when the pot is soon empty again. Due to the porous nature of the balls the nutrient solution is wicked up passively and held constantly moist with a lot of air gaps in between.
