Organic nutrients provide all the same nutrients as synthetic and can contain particulate matter that is known to clog some hydroponic equipment and are often used more for soil and soilless based media than purely hydroponic setups. They can take longer to break down into readily available materials like minerals that plants use to grow.

Be sure to check out our Nutrient Buyers Guide to help you purchase the right nutrient for your growing needs.
