I searched the forum all over but didn't find the last few answers I needed. I'm looking at T5 HO 4 foot 8 bulbs. I wanted to get two 4 bulbs, but the 8 bulb is a lot cheaper. Anyhow, Can I use the cool white and the blue bulbs together? The light I'm looking at comes with 8 6500k bulbs. I take it that's for veg? I figured I could just buy two of the 3200k or 2400k bulbs and add them when it comes to flowering. the bulbs are 54 watts per one. The only brand I've looked at is Sun Blaze. Seems to be a well-known brand. Any info would be great! I'd love to go cheaper but at $209.00 doesn't seem you can beat that price for the watts, plus little to no heat.
