This product is amazing. Not only do I use it but everyone I know does. You don't need to wait for a problem to use this - it will help your plants thrive from the first day you add it. The larger size is an amazing buy for the value. Make sure to store it in a cool and dry place.

This is a hands down great product. Easy to use and its a powder so it dissolves fast. I add it to my water with an airstone going in it first before any of my Nutes. Plants are way more healthy with this product.

I use great white as a preventative measure against root rot in my RDWC system. works great and really helps root production! Costs a lot and very difficult to find in Canada but it's worth it!!
