Earth Box Organic Growers?

Anybody else using Earth Box or other sub-irrigated systems?

I'm about halfway through flower on my first run with this style and I've just popped a couple seeds that I'll be doing the same with. Previously I've grown hydroponic and with soil in felt bags.

I'm really liking the ease and simplicity of the living soil SIP system. I can water with plain water or add a little bit of molasses or make a tea if I feel like it. I no longer have to water daily or mess with mixing liquid nutrients and checking PPM and pH. It's really made everything simple and more enjoyable. These plants are at least, if not more healthy than my past grows. When I check on them after the lights have turned on they always have up-pointed praying leaves.

I'm hoping to hear from others experienced with this style and to share tips and tricks.

I'd really like to hear what others are doing to prep their box for the next run. I was thinking of letting it set for a few weeks with some cover crop (probably clover), add in some worms, and hit it with compost teas and bacteria to break down the root system left by the previous grow.
