Black Pearl Organics

Black Pearl by Grotek is an Organic Fertilizer that Regenerates Previously Used Soil

Black Pearl by Grotek is an additive used to condition substrates, or recondition those already used, with nutrients. It provides both macro-elements and micro-elements, activating beneficial microscopic life for your plants.

This product isn’t suitable for automatic watering systems because it contains ingredients that aren’t water-soluble and will obstruct pipes. It can be used in hydroponic systems without soil, as long as you water by hand or let the water drain from the substrate.

The best way to use it is to mix it with substrate, so that the nutrients activate the beneficial bacteria and fungi. This way, you’ll ensure that when the roots of your plants colonize the substrate, they’ll always find food and an army of microorganisms ready to defend them.
