You just need a good plant light. I actually just trimmed up my ficus I have in my enclosure. Its dropping a lot of leaves but also definitely growing like crazy. I use one of the arcadia jungle dawn led bars. I'm sure a 1 or 2 65k bulbs would help it also
Nice colors. I'm waiting to see my dude fire up when he catches a glimpse of my 4 month ambilobe as well lol never seen him fired up so will be interesting
