@@Billyandbarb,Yeah it's an oxypot 4. It's strengths are that it's easy to maintain 1 reservoir for 4 plants rather than having independent ones, I also have a bluelab guardian sensor in it with a panel that tells me the EC, temperature and pH. I fitted a port in the front making it super easy to drain and fill The disadvantage is that you can't really move the plants making the plants at the back more difficult to access and it also means you have to have the same nutrient schedule for every plant.
