Thanks for your help, ohh yea and im running roots organic soil mix!

i guess they are selling them just as generic wal-mart brand now, same pot but not with the name brand...... maybe wal-mart bought them out or something. Anyways got the ladies planted in there now, guess I will see how they workout and right up a review or something

dont know about those but we had some plants outside in an earth box and the grew way faster then the potted ones

well i guess they worked ok, however the roots never grew down into the "spa" so i dont see how that would benefit anything. So i guess they would work just as good as any old pot.
