Hmmmm... we have a problem again. With 11 plants at least 1ft tall and spreading out, and one set of sprouting Poblanos in the front, the plants are getting crowded. I'm thinking that the best method to resolve this issue is to build an identical frame and stack it on top of the existing one. Of course this new structure will stand on the floor and not the cabinet it is sitting on now. That would make a 6ft tall duplex box with 2 separate light sources. I may even get a large reservoir and have the whole thing stand on that. Or I can even figure out something with some snap together wire shelves I have. I'll update as I get more ideas.
