The main task you must perform is the weekly water change (i.e. A "drain and fill").


  • Every week, when it's time, the Grobo will notify you to change the water.
  • This process normally takes ~5-10 minutes to complete. You can do so by going to the Maintenance menu in the Grobo app. 
  • Then, your Grobo will dose the plant's meal about 5 minutes after the drain and fill is done.
  • During Germination, Transition, Flower and Flush you will be prompted with a "Your Grobo is Thirsty" notification 2-3 days after your drain and fill. This is when you will do what we call a "top-up" of your water tank to make sure it is at the optimal level for your plant's health. 


As your plant grows, your Grobo will also teach you training techniques, when to do them, and how they optimize your growth for the best results.
