So I think I have my basic setup for the time-lapse photography for checking out those stipa awns. Using one of Greg's aquariums, a camera, tripod, computer and such. I'll be able to change the humidity soon enough and really start the experiment.
And here's my setup. Off to the left of the aquarium is the 500W halogen light. The seeds and black felt are inside the aquarium. In front of that is the camera with a blind on the front to help knock down some glare from the front glass. Attached is the computer, which is what I'm using to control the time-lapse.
