600 Watt High Pressure Sodium bulb

When the Sun is burning hot in August and the days are starting to get short, flowering plants recognize that it is time to start the budding process. These High Pressure Sodium (HPS) bulbs are meant to simulate that late season sun. 

For use in the budding/flowering stage. Use MH bulbs for the seedling and flowering stages. You can buy them here.
