Sealing it Up

After the maiden run of the ebb and flow system I noticed the ports into the grow tables were leaking slightly. So today, I pulled the system apart and siliconed the ports. Below are some photos of the process.

I removed the ports and applied silicone around the holes.

Silicone was placed on the lip of the port.

Then the port washer was placed and turned 1/4 turn to evenly disperse the silicone.

The port and tubing was threaded through the hole in the tub and the fitting tightened.

A detailed view of the ports. These were purchased from the hydroponic supply store. Others have made a similar design from PVC and supplies from the local home supply store, but for $3.00 they were worth it to be right and work.

View of the tubes running into the reservoir. The drain tubes are 3/4" and the fill tubes are 1/2". Since the reservoir is 28 gallons, I decided to place two air stones into the tank to ensure proper aeration of the nutrient bath.

Another view of the tubing and reservoir. The timer on the outlet strip controls the water pump. I have it set to run every 3 hrs for 30mins at a time. The air pump is also plugged into the strip.

More to come...
