Know before you buy
This formula is specifically designed for the mid-to-late flowering phase, supporting your plants from weeks 5 through 10. It is best introduced once the initial stretch is complete and the plants are focused on bud development and filling.
Yes, because it is a fully water-soluble powder, it is versatile enough for use in both soil drench applications and various irrigation or hydroponic systems. Its high solubility ensures it won't clog emitters or irrigation lines.
EDDHA iron is a chelated form of iron that remains stable and available to plants across a wide range of pH levels. This ensures your plants can effectively absorb essential nutrients even if your growing medium's pH fluctuates.
Yes, the formula is designed to be applied as a foliar spray or a soil drench. However, always ensure you are following the recommended dilution rates to avoid leaf burn, especially during the sensitive flowering stage.
The dye-free formulation means the solution will not be brightly colored, so you will need to rely on your measuring tools rather than visual cues to ensure the product is fully dissolved. It is a cleaner option that prevents staining on equipment and growing surfaces.
The high phosphorus content (30%) is the primary driver for bud development and density. By providing a lower nitrogen level and a higher phosphorus and potassium ratio, the formula shifts the plant's energy away from vegetative growth and toward flower production.
