Hey guys I'm just wondering, I have a decently small box setup and with the CFL's I have now that I'm using for veg the temperature is about 82. Once I begin flowering I'm going to be using a 400W HPS system.. I have had all intentions on buying a cool tube (well a Bake A Round) but just in case the temperatures are still too high I could put a smaller bulb into the ballast without any problems right. Like a 250W ?
