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.
Like the organic version, our All Purpose Boost 8-8-8 sets the standard for versatility of use through all stages of plant growth. If there’s only one product you can choose from the entire catalogue, this is one capable of providing the widest array of nutrients for your garden. Practically foolproof in application for most plants, this fertilizer formulation is appreciated by both the novice and master gardener alike.
Save time by calculating exactly how much material you'll need for your garden. For both in-ground and container gardening, calculate your soil and nutrients needs in one easy step!
