hey, i recently sparked a interest in growing hydro, and i dont know nothing about it, im used to the old school method growing in soil thats all i know how to do and im pretty good at it, but i wana go hydro i was looking at all the different setups and its all chinese to me maybe someone could help me out. i want to set up a nice 6 pot system, thats the easiest to grow, maintain and to build (i plan on doing it myself). my question is what setup should i use i was thinking of the ebb and flow system. i dont understand how it works where do all the roots go. can someone please help teach me about this system and how i could build and maintain it for cheap o and btw i could only grow as much as a 400w mh / hps will let me.
