I've been using a spa PH tester. Maybe not as accurate as a meter but I believe it's close enough. As far as cloning, the two that I have that are still with me were cloned in rockwool. But, I can see myself losing them as well.

The guys on this forum are great! But I'm beginning to think that dirt is my future.

Congrats to Latewood! You are one of the Guru's!
