This is just for your information. I'm currently earning a horticulture certificate from U of Guelph, Ontario. It is completely online. I really just wanted to increase my general knowledge of my most favorite subject. I didn't know what to expect - I've been out of College for years - but I found most of the classes informative. And some actually challenging (designing the landscape is not my strong point. Engineers like straight lines. But at least now I recognize basic design elements!). Anyway, my last class is intro to soils and plant growth. Guess what we'll be covering as well - hydroponics!! So, I have 12 weeks to pick the profs brain on growing cucs in an ag! If we have other questions, I can pose them as well.
Here's the certif info:
