Days 50 - 56
Last week, I had a major lockout issue with my plants, so Iβve started monitoring both the irrigation and runoff water closely. I had to do three rounds of flushing, but after that, my lady started to recover, which was a relief!
Since I'm going on vacation for the next 10 days, Iβve been working on setting up an autonomous irrigation system, which I successfully implemented and built yesterday. It uses three 12V water pumps controller by Arduino Uno via H-Bridge motor drivers, each dedicated to one plant. The system runs from 9 a.m. to 11 p.m., delivering around 250 mL of water per plant per session. This means each plant will get approximately 2.5 liters of water per day.
Iβve mixed all the nutrients in advance. I know the ideal scenario would be to add the fertilizers just before each irrigation session, but unfortunately, thatβs not possible. Still, itβs better than nothing. The system has been running smoothly since this morning, and so far, the cycle works fine. Iβll improve it further when I get back from vacation.
To prevent any future lockout issues, Iβve extended the irrigation cycles throughout the day to ensure the coco stays consistently moist.
