Get some 24x36" white featherweight board from a dollar store (cost: $1 each). Try placing one or more of the boards so more soft light falls on the plant. If your ceiling is white, aim a gooseneck lamp upward, and use a CFC bulb so you can soften the light even more by taping a paper towel over the cone. I guarantee you'll have fun playing with these simple light sources.
Along the lines of what I was thinking...some kind of reflector to even out the light...most of the time lapses I take are of sunrises...so the clouds are my friend......takes about 2 hours...this little adventure takes 3 days...and I didnt even consider the effect of passing clouds on natural light
