Oops..sorry about that...I guess that's kinda important. No, it is just one plant with a lot of undergrowth. At the top I have my carbon scrubber and blower which takes up the top 10 inches of the cabinet, but it's already as high as it will go. The light is already pressed up against the blower as is. I thought about cutting the bottom out of the cabinet to drop the bucket down, but I only gain about an inch or two (at best) and lose a lot of structural integrity of the box. Thanks so much for the reply!
