This is a very specific needs nutrient supplement. Rock Absorbalight’s main goal is to help level the playing field for crops out there that, on one hand, can be subject to any manner of various, space constricted environments like tents and small grow huts. Those smaller spaces really can become an issue in restricting artificial light getting amply distributed to all plants. This is a foliar spray which means it will be applied and fed to your plants directly onto the leaf surfaces and not through the roots. The specialized wetting agent built into the product helps insure that the foliar spray will successfully stick to the foliage in order to deliver all of the nutrients, so that your plants can maximize their response to artificial indoor lighting or even to natural sunlight via the increased chlorophyll production.
