Well Letsburn,

Interesting questions to add my two cents to so here I go. First question is a little hard because it depends on your light. A CFL like yours maybe two or three inches. A 400HPS like mine about 48 inches. You feeling me so far?

Now question number two. Vegation can be as short as three weeks or as long as a year. As far as size of plant at any stage of growth will depend upon the use of a CFL or a HPS. You still feeling me?

P.S. You want more growth get more light
