  • Liquid KoolBloom Professional is highly concentrated and should therefore be used as part of a balanced fertility program. Contact our Technical Services team and learn more about how Liquid KoolBloom Professional can benefit your crops.
  • Liquid KoolBloom Professional should be used during the early through late flowering phases and be replaced with General Hydroponics® Ripen® during the final phase of flower for optimum results.
  • Liquid KoolBloom Professional is compatible with soil, soilless medias, coir, hydroponics and is suitable for fertilizer injection systems.
