Here's a link worthy of having everyone check out, who doesn't mind messing with simple electrical. Just throwing this at all of you cheap fuckers like me who also like to learn too. I'm also thinking of leaning into the whole computer controlled grow op. Anyone have any experience with the computer control aspect? I see you can buy simple relay board kits to hook to old computers, to build or already assembled. Looks easy enough. I just wonder about power outages and the computer rebooting back to it's original state. This conversation came up way back but I don't think it was covered much.
