I currently have a sunlight sheds cool cab and thought that getting the LED upgrade was a good idea. Since i have had it i have learned otherwise. i am going to change the lighting setup and try again and will hopefully have better results. Does anyone know what would be the best ballast. Quantum, lumatek, or nextgen. Should i go with a 600 watt or 400 watt setup with this cab. I am going to use hortilux bulbs but i cant find a 600 watt MH bulb in this brand, do they not make a 600W MH?
