Usually the breeder will indicate if it’s Indica, Sativa or Hybrid strain. Most strains these days lean more to the hybrid side. If you make a mistake and select an incorrect recipe, it’s not the end of the world. As you approach the end of the grow, your notifications will prompt and educate you on what to look for in making a harvest decision. If you have a long flower Sativa strain but selected a short Indica strain recipe, you will quickly see that your plant isn’t matching up with the notifications. The recipes are designed to allow you to extend them or cut them short. The Grobo is an automated system, but you are ultimately in control.
