I'm going to set up and get going again, but this time I'm going ebb and flow. I've never done it before, and I'm going to be building the system myself, rather than ordering a pre-fab job. I'm thinking something exactly like smarmy's DIY thread http://www.growkind.com/forum/showthread.php?t=24367, with the box-store bins, etc. How do you change the res if the table's sitting right on it? I can see just lifting it up to pour nutes in, and making a drain plug like a water cooler in the bottom, to drain it out, but lifting a tray of plants 6 weeks into flower I can't see doing with any grace. What's the secret? Fellow grower just dropped off a months worth of GWS, which I have happily just tubed. Grateful for friends :bong-2:
