Okay I had two 24" flouros and one 18" flouro, the 18" wasn't called a "plant light" so I bought a gro-lux bulb for it. I am now 20 days into flowering and decided to go out and get some more lights. I bought another 24" and another 18". All the bulbs produce a "natural daylight" bluish light but I decided not to buy another gro-lux bulb for the 18" and the bulb it comes with produces a very yellow/orange light. Is this good for flowering, or is it just a cheap ass bulb. If it is good for flowering, should I take the gro-lux bulb out of my other 18" and replace it with the yellowish bulb it came with?
