Here's the deal on hydroton.
For the first week of use, you can add pH down twice a day or more and it will STILL rise! HT needs to be pre-soaked before use- big tub, air stone to mix, add pH down, go away 12 hours, come back, test pH, more pH down, repeat until it holds stable at around pH 6.
Wrinkly leaves are a common sign of high pH problems.
stinkyattic Reviewed by stinkyattic on . Help noob with new clones PLEASE! I have had my girls now since December 14th. I am trying my best to get these going. I am using the Lucas method with GH nutes 0-5-10 B-M-G pH is 6.15 PPM is 740. I started them on this on Dec 30th with half strength for a day and a half. I had to change to full strength due to a bone head move that caused a leak. The plan was to run 1/2 strength for a week and switch to full. I had a res with full strenth when I had the leak so just switched out to full early. Water temp is 70F two long air Rating: 5
