I’m new to Green Rush but not growing. Over the years I have MANY nutrient lines from liquids to salts and everything in between. What I have learned over the years is I don’t need a six part nutrient line to yield the best results. Simple is best in my opinion and it doesn’t get much easier than Green Rush. It’s literally a Grow and a Bloom formula. I do supplement with the calmag and the seaweed extract, though I use both sparingly. The results have been fantastic. Simple and easy to use is where it’s at and that’s why I appreciate Green Rush. The customer service has been super responsive too. Thanks!
