Thanks, Low-Rdr, for the info and the pic. I'm glad to hear they will still help even if not placed inches away. I bought 4 of the 23 W lights yesterday and have them perched on a chair-back, and some shelves, and on a wall hook. (Improvise!) Now when I go into the room I feel like I'm walking into the sun! I plan to redo my setup when I do my next grow in Sept. Better light planning. But the girls seem to be doing really well.
