No, the Quantum boards do not have the option of changing the spectrum. Its not going to make a big difference to your crop if you stick with 3000k or 35000k all the way through. And yes, you will need a exhaust and fan if you are growing in enclosed space and not outdoors. It is important that the air is continually getting changed in the grow space. $200 will get you a blurple LED suitable for a 500 x 500 mm area max, will do the job. All depends how many plants you want to grow and the dimensions of your grow space. If you look on ebay they will tell you on the specs of the lights the area it is suitable for, as they will always state best case scenario take a quarter off from their estimates. I think one of the sites sponsors sells on ebay.
