Compare General Hydroponics bloom boosters and finishing nutrients by their role in flowering, fruiting, and late-stage feeding. Explore Liquid KoolBloom, dry KoolBloom Ripening Formula, Ripen, and FloraPro PK+, then check the instructions for your chosen program.

These products have different concentrations, timing, and companion-product requirements. Follow your feeding chart before adding a bloom product or replacing another part of the program; products in this collection are not automatically interchangeable.

Match the product to your flowering schedule

Start with your base nutrient program and check which bloom or finishing products its chart specifies. Review the stage, rates, and mixing directions, and use the combinations specified by your program.

This collection also includes General Organics BioBud, Terpinator, and Purpinator. Compare their individual instructions and schedules rather than assuming all products are used only at the finish.
