there is a ton of information on the Lucas formula here on IC. I fyou learn to use the search function here at IC you will be much more productive researching rather then asking and waiting. Plus it is something that has been discussed countless times.
If I even start to describe it I would be typing pages, I read the orginal luca formula thread at another site, about 50 pages +, at least 10 times.
It is a simple formula to use, and great for begginers. Search, and good luck.

Lucas formula works VERY well. Check my photo gallery, most everything their was grown using Maxibloom.
