    Plants are super GREEN!

    Posted by Brad Ingles on 23rd Jun 2025

    I’ve never used this type of iron before and always had issues with iron dosing due to my hard water. This stuff goes a long way and you only need a tiny amount. It adds a tiny tint of pink to the water after you dose but it goes away quickly and some days I don’t even see it. It’s a very fine powder and dissolves instantly. My green in plants have never looked so rich and deep green until now, really like this stuff,
