Perlite pH problems (danielfp?)
Hi, I stumbled across a helpful post awhile back about hydroton pH issues:
Forum member danielfp (I can't PM him!) had a good solution (pun) for dealing with this issue. I'm trying to grow now using perlite and see that there's a climb of about +2.0 pH after water and nutes sit in the bucket of perlite for a day. My question is, will the vinegar solution in the above post work for perlite too? Anyone else have any tips for controlling the pH in perlite?
