It combines a grow diary with analysis: every measurement of feed and runoff goes to the right plant, the app works out the deviation from the target and gives a recommendation on the nutrient dose. On top of that come calculators for climate and light, an AI advisor and a timeline with photos and notes.<\/p><p>Why the runoff? What goes into the top of the pot says little about what reaches the roots. The water that drains out shows it: if its EC is clearly higher than that of your feed, salt is building up in the growing medium.
