Yup, Dave is right. They are in all the grow catalogs. I like the 400w MH/HPS switchable ballasts too. All you do is flip a switch and change the bulb.
They also have 400 w MH conversion bulbs if you have a HPS system.
FunkycDog: It sucks being poor.....I know too! I'm using FoodSaver vacuum bags to grow in right now..LOL
