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.
