Royal Black chelates nutrients like magnesium, calcium, and iron. It provides natural carrier compounds that transport nutrients and vitamins into your plants to more efficiently enhance their growth.


• Enriched with a small amount of potassium silicate for extra plant benefits such as            stronger cell walls and increased chlorophyll production.

• There is no need for any extra silicon products when using Royal Black!

• Suitable for soil and coco and works well with any branded fertilizer or additive.

• Pre-treat pots with Royal Black, especially when using coco (this does not contain any      humate matter like soil) to get plants off to a good start!
