Even better growth with Rinse-and-Refills

rinse and refill siphon

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! 

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 and easily drain all the water and nutrient solution from the water bowl into a sink or a bucket. Add fresh water and nutrients as usual, then click the 'Reset' button to reset the nutrient timer. 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.  

If you don't have a siphon, simply lift the water bowl out of the base and empty the water into a sink or bucket, and proceed as above.
