The spec says you can run ethernet cat5 for 100m without signal loss.
With some careful planning you could use PoE to get networking & 48VDC (which you'd step down to 5V for the pi) and networking down to your greenhouse.
If you've got a single phase 230V ring or spur you could use powerline ethernet.
Most of the volunteers on the forum don't want to write your code for you (that's a fee based service in my world) but prefer to give you hints at where you should be looking to write your own code. We're quite willing to help you shoot the bugs in code you've written or code you've "borrowed" from the internet.
There's no formally defined support on this forum, that's not part of the Raspberry Pi Foundation or the volunteer's remit.
For the right fee I'll write code.
