THAT IS REALLY COOL!Originally Posted by wh33t
What IS the pH in question? I would LEAVE it alone. If your pH is somewhere between 5.5 and 8.2, just leave it until the bacteria are more established in about a week. Thoroughly rinse some eggshells and put them in the grow bed. DO NOT CRUSH THEM INTO TINY PIECES. Just put the large pieces in there (better yet, keep it easy to remove). The pH will raise and hover in the 7's once this balances out.
