Welcome to How to Hydroponic! In this episode, we're diving deep into one of the most essential components of indoor gardening: lighting for hydroponics. If you’re serious about growing indoors, understanding the differences between grow lights and regular bulbs, the role of light wavelengths, and the types of grow lights is crucial. This video is perfect for beginners and anyone looking to optimize their hydroponic setup with the best lighting options.
