I said I'd post a pic, so here it is. It gets light at bottom from south facing window & some light from upper window.
That leaf is about 4 ft long - see tip on top of tv. I marked it w/ red line (below).
I since put a halogen lite at bottom (no place to put it to shine down) & propped the leaf up.
That 2 inch high new leaf is now over 2 ft in just a couple days! I also gave it some banana fuel. Extra lite, lots of water & fert must've done it. Thanks again.
