Herb Superb is the best!

Simply The Best!

As Tina Turner sang... Simply the best, better than all the rest!

I've been using High Powered Organics for years, and use most of their products from the soil to the amendments. IMHO you will not find better quality products, the soil is a work of art. I've tried all the other big name organic soils and they don't even compete. Just look at the ingredient list of Gro-Dirt, jam packed with the best of the best and is IMHO Australia's best organics.

If you want to grow organically don't muck around with cheap soil and inputs, get this and you will be rewarded with the best yield and flavours from your garden. HPO pays for itself many times over and the team behind the company are just awesome!
