hey man - if its worth your time & effort invested, why not also invest in a good grow book, it'll answer all your questions and then some. You'll be glad you invested in yourself and your garden. Its also easier to look it up in a book instead of waiting for someone to maybe tell you the right thing on a web site. You can find reviews of the books before you select one. I liked Jorge Cervantes book the best out of the five that I bought. :rasta:
