I know there is a ton of info about CFL grows and all that but I cannot find anything that answers what I need to know. I have been growing with 4' shop lights 6500k with the blue spectrum but now I am switching to the compacts because they are a little more practical for a grow in a smaller space. Well I picked up a few 2 packs of the 6500k bulbs in the blue package like I expected they would be in, but when I get home they are 6500k but dont have the blue spectrum like my shop lights. Are these fine to use alone? I have seen some pictures on here of CFLs that look like they have the same spectrum but it's hard to tell. Thanks.
