Best Grow Lights for Seedlings: LED vs. Fluorescent for Starting Seeds

Cannabis seedlings require a light intensity of 200-400 µmol/m²/s over an 18-20 hour photoperiod to thrive without photoinhibition. While traditional fluorescent fixtures provide excellent coverage for propagation, modern T5 LED strips offer superior efficiency and cooler operation for dedicated seedling trays. Dimmable LED panels are the best choice for growers seeking a versatile fixture that spans from seedling to early vegetative growth.
