Professor’s Extreme Boost
Professor’s Extreme Boost is a premium high-strength PK flowering additive designed to maximise flower size, density and final harvest weight during the critical finishing stage. Formulated with highly concentrated phosphorus (P) and potassium (K), it provides plants with the essential nutrients they demand during the last weeks of flowering when bud bulking and fruit development are at their peak.
As flowering plants mature, their nutritional requirements change significantly. While bloom stimulants are ideal for initiating flower development, the final stages require a much stronger PK source to encourage dense, heavy flowers and maximise overall yield. Professor’s Extreme Boost delivers these nutrients in an extremely concentrated, highly available form, allowing plants to rapidly absorb what they need to complete the ripening process.
Using high-grade mineral ingredients, Extreme Boost promotes harder, denser flowers, increased fruit weight and improved crop quality. Many growers also report higher resin production, improved essential oil content and increased brix levels, resulting in healthier plants and superior harvest quality. When used correctly during the final 2–3 weeks before harvest, yield increases of over 20% are commonly achieved.
Suitable for hydroponic, coco and soil growing systems, Professor’s Extreme Boost is simple to use and integrates easily into your existing nutrient program. It is ideal for growers looking to maximise the size, weight and quality of flowering and fruiting crops before harvest.
