Begining to think Hydroton REALLY SUCKS Here the deal have been soaking a batch of washed Hydrotron in Ph h2o this is the 4th day now that its back up to 6.5 after being dropped to 5.1 after 12 hrs. this last time. WTF how can there be such a diff. from one bag(batch) to the next?? this is why my garden is having problems I am sure. any thoughts or help would be great. Daddy Rating: 5
