Yep, thanks for the response. I've got a bunch of raw dirt down now and was thinking that if I could get some aggressive desirable plants planted in the miscellaneous spaces, (next to walkways between beds, under the water tank, beneath the planting tables, etc.) I might be able to get ahead of the weeds. Clover is probably my fall back, although I'd prefer something with more "table value". Some of this space is in the greenhouse so it will benefit from higher humidity + temps, as well as a longer growing season. Thanks again.
