Interested as well. I'd love to hear about good internet sources or blogs on this topic.
I've already implemented an irrigation system and an automatic chicken door — a greenhouse controller is next.
I usually use AliExpress components, but I’d really like to find more robust, reliable hardware. The quality often feels more like toys than tools.
Farmbot looks kinda cool. I wonder how well it does exposed to the elements. https://farm.bot/
I'm planning to build some variation of a greenhouse controller for a mini seed starting greenhouse.
