Plants are super GREEN!
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,
