I think you guys are tripping on the hydroton I have been using it 10 years and would use nothing else. I rinse them off real good put all the plants in, and do a res change the next 2 days in a row to get the residual dust off. No problems at all. Ph creep is pretty normal I set mine at 5.8 check on them 2 days later its at 6.2. the only time ph creep is bad is if it goes the other way say from 5.8 down to 5.4 and so on. Normaly that means you have some bad bacteria in the res. a little h202 clears it up. I dont like anything that retains moisture or nutes ie coco, rockwool, dirt you have way more control with a nuetral medium.
u.g.u Reviewed by u.g.u on . 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
