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. 
Different growing media available on GrowGuru:
There are several growing media available for hydroponics. GrowGuru offers hydroponic systems, including a variety of growing media. Some of the growing media available on GrowGuru includes: 
  • Jiffy peat pellets, 
  • Expanded clay pebbles
  • Rockwool/stonewool starter plugs 
  • Perlite 
  • Coco peat /Coco coir (coconut fiber)
  • Vermiculite
Each option has advantages and disadvantages. The decision between aggregates will be influenced by a number of factors, including the size and type of plants you want to cultivate and the sort of hydroponic system you employ. 
Selection of the best hydroponic medium:
In order to select the best hydroponic media, the following features need to be considered:
  • Easy handling
  • Affordability
  • Good seed to medium contact
  • Provision of physical stability to plants
  • Thermal insulation to the roots to meet the temperature swing
  • Inertness
  • Ion exchange capacity
  • Water holding capacity
Different systems, climates, and media configurations may be ideal for different crops. All of the above mentioned qualities are crucial to the grower’s success. GrowGuru’s substrates fulfill the requirements of the best-suited hydroponic growing medium. It is better to experiment with various media before scaling up to find the optimal answer to your expanding needs.
