Green Planet

Green Planet Bud Booster

Bud Booster is Green Planet’s classic powdered bloom additive, designed to maximise flower mass, size, and quality during the flowering stage. This concentrated formula delivers high levels of phosphorus (50%) and potassium (30%), the two key macronutrients that fuel flower development, nutrient uptake, and carbohydrate production. It also contains boron to improve sugar transport and nutrient mobility, as well as a small amount of nitrogen and vitamin B1 to support metabolism, root function, and stress resistance. By increasing phosphorus and potassium at the right time, Bud Booster encourages plants to set more flowers, build denser buds, and improve overall quality. The powdered format is easy to use and dissolves quickly into feed water, making it suitable for both beginners and experienced growers. Compatible with soil, coco, and hydroponic systems, it integrates smoothly into any nutrient program as a simple, high‑impact bloom enhancer. Bud Booster is especially valued for its ability to provide visible results, larger, heavier flowers with improved structure and increased yield potential, all without complicating your feeding schedule.

Bardee

Bardee Superfly - Fast Acting

Bardee Superfly Fast Acting Natural is a certified organic fertiliser crafted from Black Soldier Fly frass and exoskeletons, turning food waste into a high-value soil input. It delivers a quick nutritional kick while steadily improving soil structure with a rich load of organic matter and a broad spectrum of beneficial microbes. The result is vigorous vegetative growth, stronger root development, and improved moisture retention, particularly useful in sandy or tired soils that struggle to hold water and nutrients. Beyond NPK, Superfly contributes meaningful calcium and trace elements to support sturdy cell walls, balanced growth, and better stress tolerance. The naturally occurring chitin from insect exoskeletons acts as a biostimulant: when chitin fragments contact plant root zones, they help prime innate defence pathways, encouraging plants to respond more robustly to common soil-borne challenges. This gentle, biology-led approach underpins healthier canopies without relying on harsh synthetics. Because it’s low in salts and near-neutral in pH, Superfly Fast Acting Natural integrates cleanly into most soil or potting-mix programs for vegetables, herbs, ornamentals, lawns, and fruiting crops. Use it to power starts and transplants, to revitalise compacted beds, or as a steady top-dress through the season. Consistent applications build crumb structure, increase cation exchange capacity, and enhance microbial diversity, the foundations of resilient, productive soil.
