This is NOT the correct ring culture . The correct equipment is a bottomless pot with a 'moat' around it. Liquid feed is applied to the pot and the moat filled at the appropriate time - when the first truss has set - and normal watering is OUTSIDE the moat. Tomatoes have two root systems and this applies water and feed to the right places. I have been using this system with spectacular results for over five years.
