Expandable Hydroponics System from Junk - Flood and Drain

Step 6Assembly

Assembly
Place assembled reservoir bottle into secure position and secure planters in an inverted position, several inches above the reservoir (this allows space for interconnecting the reservoir and planters). Connect the 3/8 inch tube from the reservoir to the nipples on the planters using remaining 3/8 tubing and TEE connector as required. Try to keep connections as short as possible, kink free and above the reservoir for proper drainage.

Connect air tube to aquarium air pump.

Fill reservoir through planters, if desired or by simply unscrewing cap and removing the reservoir bottle for maintenance. Do not overfill reservoir, it will be plenty once the plants are added.
At this point it should be fully assembled and ready to test. Test by turning on air pump and check for air or water leaks. Fill any leaks with hot melt glue.
