This thread is a little old but I thought I would post some up to date info on here for people like myself who happen to stumble upon it. I notice a couple of people were asking about a place in or around Portland, for years I have had to make the long trip up to the urban garden store in topsham from the same area and have just recently discovered a new shop that is much closer to P town. The store is called liquid sun and its in Gray, just off exit 63, take a left off the exit, go over the bridge, through the light, and its on your left across the street from Riteaid. Small shop, same guy in there every time Ive been there, good service and friendly, plus they carry some stuff that UG doesnt, like the full range of Canna soils and nutes, which Im currently trying and very happy with. Check it out, and do me a favor and tell him dudeman buddyguy sent you.
