Thanks LOC and SRH! I hadn't thought of using a net.... I'll look into some bird netting or some clear plastic/glass from HD. I'll scramble and see if I can salvage a nugget or too!

BTW: I actually flipped over to flowering when this particular beast was 9 inches high. I did the 36 hour in the dark trick I learned here, and the nodes then were really close. As soon as the switch was on she just started reaching...then it was a race to the top of the cabinet. She won... Thanks for everything-off to HD!
