Yeah, best temperature is about 70°F, moderate sunlight, decent airflow and ~50% humidity. Mold and either spindly or stretchy growth are the biggest problems with microgreens...I've lost tray after tray to either mold or spindly growth :(.

Also experiment with light positioning, if you're growing under artificial lighting!

Right on. That's what I figured. I think we need to either bring them inside or do some sort of a double greenhouse with heat mats. I'll keep ya posting on what we end up doing.

Definitely do, I am living vicariously through you as my microgreen operation is small right now :)

Everyone's got to start somewhere. The good thing about micros is you can get quite a lot of return off a relatively small space. We're gonna have to move our operation inside for the winter and all our micros will be produced via a tower system. I'll try and do a write-up on it soon.
