I'm going to be setting up a 36 site set up using a multi pot ebb and flow system. I'm running around the whole internet looking for a system but some things don't add up. I just want to make sure i have a big enough water reservoir and controller to handle it. i only found 1 site that sells a set up with 36 pots with 3.5g but with a 55g for water. What would be the best way to set up 36-48 pots.
