It has been a while since we posted anything. Our focus has been on stabilizing the GrowBot hardware / software. Fortunately the overall design has remained very productive and easy to maintain.
We tested a new prototype starting in June that worked great. Very stable electronics and software. The only challenge with the design was the massive labor involved in building just one GrowBot Control Board – over a month.
We are working on a printed circuit board to make the new design affordable.
