Hello! I do a bit of programming (I know how to take other people's code and adapt it to my needs, basically) and I'm thinking of growing in a greenhouse when I buy a house with some land on it.

While I like to garden and know a basic level about it, I want to know if anyone has experience with using automation in a greenhouse?

I just basically want to connect irrigation, misters, fans, heaters etc. to a network of sensors connected to raspberry pis.

It depends on what you mean by greenhouse.

In a professional settings the use programmable logic controllers which often have ridiculously under-powered CPUs (in comparison to raspberry pis) but are built to a high standard of quality.
They are also ridiculously expensive and use obscure and proprietary programming languages which stems from a time where raspberry pis & arduinos did not exist.
Not that it matters, the companies that run theses systems make billions.

A regular garden greenhouse is just fine without any kind of programmable automation, people have done it but it's a dated approach imho.
Because you have to control mains voltage you have to add a relay hat, get a special case that can be in a water proof enclosure etc.
But If you set your mind to it go for it:

(link to github on the lower left.)

Else just get a Sonoff 4ch or similar. (google it)
They have a basic app for the phone which covers the vast majority of cases, if that's not enough you can also program them using the arduino ide.
