I'm glad to hear that because I just ordered a hortilux bulb this morning. I don't think I have much more than a few weeks left of flowering, but it will be nice to have for my next grow whenever that is. So you do think it makes a pretty noticeable difference then? I noticed that hortilux is one of the cheaper of the higher end bulbs. Are some of the more expensive ones worth the extra money? I tried to look at the spectrum each puts out, but I couldn't find much on it.
