Thanks for the link! I was looking at eBay a couple days ago, and most of the curved scissors shipped from China. Never been disappointed with Amazon.
Very interesting! Thanks for the link, it was a nice read. Like Marcel G, I too am critical of EI dosing. For me, and I only used EI for a month because of deteriorating tank health (got an algae bloom), I did not notice any gain in plant health. I like PPS-Pro as I can adjust it and it is more lean, and I'll adjust the new batch accordingly. CO2 is priority number one for me, which is why I run pressurized CO2 in the first place on this build--as we know, CO2 is important for building sugar in the Calvin Cycle, allowing for the plant to build its structure. I don't need a ton of CO2, but it definitely helps.
