HPS (red spectrum, flowering or blooming) & MH (blue spectrum, vegetative growth) grow lights provide intensity, broad-spectrum light suitable throughout the entire plant cycle. The same HPS or MH light fixture can be used over the entirety of your plant's stages, from cloning or seedling stage to plant’s maturity and harvest. Double-ended (DE) grow lights power both ends of the bulb, resulting in more intense light vice Single-ended (SE) grow lights provide power to one bulb end.
Commercial growers find DE grow light provides flexibility, brightness, and more efficient light. Hobbyists with small indoor gardens find SE grow light perfectly suitable. Need help?
