Hey,
I am in the middle of an LED grow right now.
If you would like to see the progression you can find the grow on here under LED grow testing the Pro-Grow 260.

Or you can visit my blog spot here: LED Logger

Personally I am having a good experience so far. I changed the light cycle to 12/12 about 9 days ago and I am now beginning to see the sexes.
I hope my page can help you decided on LED or not. It's a purely experimental grow and I hope I get results as I invested around €1,000 to get started.
I am pretty new but I did lots of research before I began this grow.

Its getting exciting now so keep an eye

take care
