Sorry, I'm getting a bit shit at keeping up!
@ hank, popham & spring - thank you all very much for the reps and the kind words, gratefully received thank you.
James & gugo; because of sponsorships etc 420 aren't keen on naming brands etc in posts unfortunately, which makes it a bit difficult to go into detail on the led I'm sorry. I'm really, really impressed with it. A few days in and the growth is noticeably stronger and healthier. Massive difference.
I'm going to start the new journal in the next few days. From what I've seen already the difference between a 125w cfl and a 200w led is enormous.
