Rinse and Refill Siphon: Keep your water tank fresh with no mess.

Plants in most hydroponic gardens benefit from periodic changes of nutrient solution. Rinse and Refill Siphons make it easy to change out the nutrient solution in your AeroGarden without disturbing your plants. A quick pump of the ball and the siphon keeps your water tank fresh with no mess.

INSTRUCTIONS:

To siphon, insert the pickup tube into the liquid, close the vent valve (the white knob on top - tighten clockwise), squeeze the bulb repeatedly until liquid begins to flow down the accordion tube and relax and let the siphon action do the work. Before removing the pickup tube from the liquid, open the vent valve (counterclockwise) and wait for all the liquid to drain from the delivery tube.  We also created an instructional video which can be viewed here.
