Grow Mediums

Hydroponic and organic growers employ a variety of growing media to offer a substrate that anchors the plants and aids in delivering water, nutrients, and oxygen to the plant roots.
Hydroponic substrates are several types of soilless grow media. There is no soil involved in a hydroponic system. Instead, plants are supported by hydroponic substrates, which give a location for roots to adhere, improve aeration, and retain moisture. Plants require a nutrient solution to provide minerals and other vital ingredients for growth because hydroponic substrates are mostly inert.Β
