Set up a wifi hotspot on your laptop-  disconnect from your home wifi, set up the hotspot with the same name as your home ssid , that should allow you to ssh to your pi (when you are in range of course

Windows doesn't allow you to create a hotspot unless it is already connected to a network - either via Wifi or Ethernet. 

However it has just made me realise my solution in my previous comment is even simpler if the hotspot is set to the same SSID & password so no need to faff around setting the RPI to connect to another Wifi network to start it off.

I'll edit it to reflect this.

I have a raspberry pi using a 12 volt lead acid battery that I use to control an automatic watering system in my greenhouse....

The problem is my wifi does not reach my greenhouse so if I want to make any alterations to the watering program I have to dismantle my watering system and bring the pi indoors.
...
So what would be the cheapest and easiest way to get wifi to my greenhouse?

Costing no more than some cardboard, aluminium foil and glue, either of these wifi reflector designs may be sufficient: https://www.comparitech.com/internet-providers/how-to-make-your-own-wifi-extender/ . I've successfully used the first, though it's a bit fiddly to assemble.

You could instead or as well use a higher gain antenna for the pi.

@jamesd Those wifi range extenders are brilliant but neither addresses the crucial design decision of whether the foil should be shiny- or matt-side outermost.......

Yes, that really is a bit of a quandry. Possibly worth trying bothways

I used outwards but the surface roughness of the non-shiny side isn't going to matter at the wavelengths involved. Though you were probably joking... Thin paint layers to match the decor would also be OK but would reduce the amplification a little due to the need to !!!!!! through the paint twice.

If money is available a higher gain ordinary antenna is the way to go. I've effectively used one of those as well.
