Thanks for your reply.

I have read and scanned that set of posts several times and here's my synthisis of 48 pages of posts in LED growing- An instructional grow log, 17 pages of Episode 3 and the few pages here to a couple of sentences.

Yep it can be done all LED but you'll get a bigger yield if you add full spectrum floros or HID as in Episode 3 with the T12 floros. And for your next grow you plan on adding HID 70's? The upshot is LED good. but adding HID or floros is better?

I know this is all experimental and learn as you grow but do you think adding other lights to the mix is best?
