Rocket posted the same email on ihub ca Feb 10 along w analysis of CWRN's fertilizer-too big a file to save and post as an image here and I dont see it in Max's compilation-but CWRN's fert tested as 55.55% iron. Since the iron fert retail products are 2-20% I assume CWRN's fert can be diluted many times-meaning it would go a long way.
