Yes, So I have heard. But I started this just to see what I could do and kept the budget low since it was just a experiment. But now I see how things are growing I'm very interested in try the different lights, again just to see what I can do with them. I am really getting into this now. I've gone from 4 plants to 15. I even got my MMC. So yes, it's getting exciting. Can't wait to finish flowering the first batch.
