I do
Like a little pump drip system

I tried a few things with my greenhouse
Water butt with submersible pump connected to a smart socket, tray watering with little float shutoff valves and a more ambitious project to link arduino soil moisture sensors to electrically operated water valves that I never got round to finishing

This is the sort of thing I'm getting at
But I think a little trickle feed solar panel with a storage battery for the pump/droppers and a small heating element to stop it getting totally freezing in winter.

I already have an overall temp/humidity sensor in the greenhouse, so I can get all smart with routines from that

Fair enough. My greenhouse was close enough to the house to make it easier just to run everything off the mains.
Plus my greenhouse heater was a bitcoin mining ASIC in a home made water resistant server enclosure so solar panels wouldn't really have cut it.

Did you find any coins? or whatever the verb is.

I mined 3 bitcoins but the FBI confiscated them when they shut down BTC-E :(
