I run Hydro setup and use Dyna FP Dyna Boom and Dyna MP. Been using Dyna for several years. I separate the nutrients in squirt bottles and I just use my EC meter to mix each nutrient to the EC I want. I'm always in hurry (kids, wife, full time job) I'm going to make a run with Blue Planet BPN and until I get it tweaked how I want. I'll be measuring each nutrient. Where can a buy the these type bottle in the lower 48 States https://www.alibaba.com/product-det...lizer-1000ml-Water-Dispenser_60413068124.html I've found a few on Amazon that have half oz and oz necks, but I want one that measures in ML If you can post a link it will be much appreciated.
