Hi, everyone I'm making the jump from hydro over to aero I have a few simple questions I want to ask people who have knowledgable in aero. I have a flood tray I want to convert to a aero system. Its a 4x4 table and only 7 inches high. I'm thinking of putting a lid on it and drill some holes for net pots to do sog. My question is, should I position the sprayers to spray from the top downwards? I was thinking maybe roots will get caught in the sprayers or something if I sprayed upwards. This way it will never get clogged with roots. However, I dont think it will disperse the nutrient solution as good as it will if I sprayed the solution upwards. What do you guys think? Also, what are good sprayers that are really reliable when it comes to not clogging? Any help appreciated. Thanks.
