Indoor Hydroponic Microgreen farming, every work has to be done thoughtfully, one of those important works is selection of seeds.
Our topic today is how to select seeds, how should the seeds be, what features should the seeds have etc.
Hydro Green Vegetables, which are grown using hydroponics technology, generally contain many nutrients, such as vitamins, minerals, and antioxidants, which are very beneficial for the body.
General Seed Selection Criteria
Germination Rate: >90% for uniform growth.
Organic/Untreated: Avoid chemicals that hinder germination.
Size/Shape: Smaller seeds (e.g., broccoli) spread easily; larger seeds (e.g., sunflower) may need soaking.
Disease Resistance: Mold-resistant varieties reduce losses.
Yield: High-density growers like radish maximize output.
