indeed. kratky has a youtube channel, he makes it super easy to understand. If you half ass it, it won't work. You need to replicate his methods, and it is super important to make sure the roots are just sitting above the pea gravel in the bottom of the netpot, water just touching the pea gravel from below. Most people end up drowning their plant by putting the roots directly int he water. They need to grow air roots to drink, water roots to get food. People drown their plants thinking kratky is done that way, it is not.
