If you go with 2 rooms and can't make up your mind. You can always buy 2 different types of lights and compare them early on. So when it's time to replace something you've got results to base your choices on. Not some forum or review! Remember there's no one who know your grow area better than you. You'll find a lot of know it alls around here. Many questions don't have exact answers. Because there's many ways to wind up with a bad environment. And when it comes to pests everyone has a different diagnosis. Same thing with nutes people argue all the time and have sides. Think it through. Read about over/under watering/feeding. Read about bugs. Read about the environment. Read about the problems people have had and the symptoms. So you might be able see the problem coming. When the leaves change color, get burned, or the plant gets infested with bugs. If you wait until it can be seen a mile away your situation will be worse. Have some form of "all purpose" fogger. You can spray plants in veg with azamax or many other things but after flower I wouldn't spray anything on my plants. But I've always got a box of foggers on hand. You don't want to waste time taking a poll or reading while your plants are under siege. Be clean as possible but sooner or later you'll get something. Whitefly, fungus gnats, but something. Those 2 are easy but it can be bad. I had a battle with spider mites they're a pain in the ass.
