Thanks! Fingers crossed :) Yeah they work really well for lettuce, spinach, herbs...pretty much all leafy greens that don't grow over 1 ft tall. I might try a bit of kale though and see how it does though, I love kale soup.
There are some people I know who are doing shelf gardens too...just one of those metal baker's shelves and then attaching LED grow strips under each one. They work great. If I had any floor space I would do that.
