Supplimental lighting for a room with two windows?

[Purple Daddy]

I have a bedroom which gets near direct light through one window until about noon, then about 75% through a front window until about 4 p/m. I cluster my six plants near the side window and front window using about 40% of a 12x12 room. I suppliment the room with two 90W UFO LED's and two standard 4ft 40Wx2 shop lights. Plants seem to be doing well and I try to keep them rotated so a different pair are in front of the morning window every few days. I did lightly spot the windows with frost so you can't really see in them but doesn't block any light. The room is very bright most of the day.

Does this seem like sufficient extra lighting?

Buy a cheap light meter to see what your receiving, but my educated guess would be that your not getting enough. I would bet that the window is your supplemental lighting.

I've seen some nice buds grown with just the 90w ufo. But I would just build your tent now, when flowering comes around your going to have to board or black out the windows somehow anyway.

You might want to reduce that room down to 4x4 or so. But I'm not a LED lighting expert. :rasta:
