Product Information:

  • Cannabis requires a lower total nitrogen to potassium ratio during the flower phase, as well as, increased levels of phosphorus. Liquid KoolBloom® Professional can help push a plant into the generative phase by optimizing the ratios of these important macronutrients.
  • 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.
