Unleash the full potential of your plants with Grenade BLACK, a powerful nutrient additive designed for both indoor and outdoor growers. Not your average PK type booster, this advanced formula, with added sulphur to increase nutrient uptake, is specially designed to boost plant performance, enhance growth, and maximise yields. Ideal for all types of plants, Grenade BLACK is the ultimate solution for gardeners seeking exceptional results. Completely plant-derived, it:

  • Boosts Plant Performance: Provides a concentrated blend of essential nutrients that enhance overall plant health and vitality.
  • Promotes Vigorous Growth: Stimulates rapid and robust growth, ensuring your plants develop strong stems and lush foliage.
  • Maximises Yields: Enhances flower and fruit production, leading to larger and more abundant harvests.
  • Improves Nutrient Uptake: Optimises the absorption of nutrients, ensuring your plants receive maximum benefits from fertilisers.
  • Supports Plant Resilience: Strengthens plants’ natural defences against environmental stresses, pests, and diseases.
  • Easy to Use: Simple to incorporate into your regular feeding schedule, making it ideal for growers of all experience levels.
  • Versatile Application: Suitable for use in all growing media, including soil, hydroponics, and coco coir.

Transform your garden with Grenade BLACK - it combines top-quality minerals, amino acids, phytohormones, and biological cofactors to increase plant energy. With optimized sulphur levels, this aids the stimulatation of secondary metabolite production. Whether you’re a novice or an experienced gardener, this nutrient additive ensures your plants achieve their best growth and highest yields, leading to a healthier and more productive garden.

Although this is a relatively new product to us at Greens, the few bits of feedback we have had has been very good, so we'd recommend this to anyone who's looking to push their plants' potential that little bit further.

Highly concentrated for increased value for money, it's designed to be used in weeks 5, 6 and 7 (depending on crop type) of the flowering phase - it can also be used from week 3 (or when plants have fully entered the flowering phase) at 0.2ml/l. When plants are at the business end the idea is to then double the dose in weeks 6 and 7 to 0.4ml/l. As always, keep an eye on your plants - look and listen to them!

NPK - 3-9-19

Available in 250ml and 1l sizes.
