I`m new to this forum and I am about to start my first RDWC grow, but like many other first timers I do need some help... My setup will be: 9 15 liter buckets 1 74 liter resorvoir And it will be in a 3x3 row The questions I do have so far is what kind of air and water pump should I use + how do I fill it up and how much????
