I've been working my on grow cabinet each season when starting my garden plants. As much as I would like a nice big tent, I like how mine has been operating. Recently started to integrate some HA on rpi4. In years past i've mostly utilized mechanical timers and the odd arduino sensor. I got a hold of a zelio logic relay which was fun to play with and more reliable then arduino i found. At least for lighting. Last thing I wanted were for my lights to go out due to a program/hardware error.
This is where I'm at this year. Currently getting another one together for taller plants so i can grow some to a fruiting stage. I'm only growing plants to get them ready for spring.
