Most hydroponic applications recommend complete changes of nutrient solution every week!  At AeroGrow, we spent years testing and designed our gardens to grow wonderfully even if you NEVER do a full nutrient change.  That's a pretty big deal!

Siphon In Use

But that doesn't mean it can't grow even better. Through testing in our labs, we've seen significantly better growth with what we call a "rinse and refill".  Here's how to do it:

Once a month when the nutrient light comes on, use our specially sized siphon to quickly drain all the nutrient solution in the AeroGarden into the sink or a bucket ( see picture to the right).  Add nutrients and water as usual then press the reset button.  That's it!  Nutrients perfectly balanced!  It's easy and takes less than 5 minutes, and you can do it without spilling a drop of water or disturbing your plants.  Best of all, you'll see a difference in the health, vitality, and lifespan of your plants.
