blinko, you get the responses you do because a majority of the people here have taken apon themselves to learn.. the very basics of growing.. you on the other hand, feel that you need to ask about .. very trivial and non problematic issues. most of the things you are asking would be covered in maybe... 1 or 2 chapters .. of a grow book.

Take the time. Read a Book. Watch a Movie.

or in the words of my History teacher, "Do your fucking homework".
