Chuck, You might like to take a look at node-RED (http://nodered.org) which is a browser based visual tool for 'wiring the Internet of Things' and I reckon a greenhouse counts as a Thing. It is written in Javascript, running in node.js, and runs fine on small embedded Linux machines like the Raspberry Pi and the BeagleBone Black. There are explicit 'how to set up' instructions for both these boards on the web site. You can start by 'wiring up' analogue & digital input pins to function blocks which make calculations and decisions, back to output pins, or to other things like Internet services. For example, you could make it send an alert to your phone (or an email, or a tweet) when the temperature goes over a limit.
You can write Javascript inside 'function blocks' for simple tasks, or if your task warrants it, extend the environment by writing your own 'node' - also in Javascript. It's all open source so you can look under the hood & see how it works. There is an active, helpful developer community emerging around it. Whatever you decide to do, enjoy doing it!
