The product, with purpose
Big flowering energy. A clear job in your garden.
Flowering changes what you ask of a plant. Incredible Bulk brings a focused phosphorus-and-potassium blend to that part of the cycle, with a low nitrogen grade of 0.1–10–25. It is a targeted addition to your feeding routine as flower and fruit development get under way.

Why phosphorus and potassium?
Phosphorus is involved in plant energy processes. Potassium helps move water, nutrients, and sugars through plant tissue. The low nitrogen grade makes this a focused addition to a flowering routine.
Good company. Different jobs.
Keep Bloom in the flowering-feed role. Add Incredible Bulk for focused phosphorus and potassium support, with Microbes in the soil-care role.

Begin at the flowering or fruiting stage. Start at the label rate and follow the pack directions as your plants move toward peak flowering.
How is it different from Bloom?
Bloom is the flowering-stage feed in the Growganica system. Incredible Bulk adds a phosphorus-and-potassium-focused booster alongside it.
Can I apply it to the leaves?
No. The pack directions specify a soil drench and say not to use it as a foliar feed.
What is in the formula?
Soluble rock phosphate, sulfate of potash, and kelp. The current pack carries a 0.1–10–25 grade.
Can I pair it with other products?
It can sit alongside Bloom, Microbes, and other inputs appropriate for your plant. Follow each label and check compatibility before combining fertilizers or other treatments.
