Well, before I could dive deeper into hydroponics, I needed to have the proper tools. As you may or may not have read in the Deep Water Cooler thread, I made a DWCooler cloner. I left clippings in the cloner for over two weeks with zero success. So today, my meter finally came in. I believe my cooler has not been working because my ph was at well over 8 and my PPM was at around 140. Keep in mind, this is my tap water. I properly adjusted the PH down to 5.8 and I'm hoping my clones take off within the next week. Just wanted to share my experience. Perhaps later tonight, or this weekend I'll take some pictures of the meter in action for those interested in a reliable / affordable multimeter.
