Mr. B's Green Trees ALL PURPOSE BOOST 8-8-8


The best of both worlds! Our 8-8-8 fertilizer is a customer favorite during growing season for pushing the limits of growth. Our Organic/synthetic hybrid formulations start with an organic base, and elevate the NPK with the addition of synthetic fertilizers including Urea and Triple Superphosphate. When you’re looking for that “boost” in your marijuana crop or vegetable gardens, and don’t mind the use of synthetics, Mr. B’s Green Trees Boost brings an explosive healthy growth and flowering from start to finish.
