I just received my Grobo unit and have started my first grow. I am using the Generic Sativa recipe per suggestion from Grobo support with Maui Wowie feminized seeds. I recall seeing a very long grow time when picking the recipe, I think 120 days approximately. I was expecting a grow time of more like 90 days. The app doesn’t show any prediction of total grow time or harvest.
Will the real grow time actually be 120 days, or is this just an estimate? How does the machine know when it is time to harvest?
Thanks in advance for help for this Grobo newbie.
