It always amazes the inventiveness of some .

Myself , I had an empty aquarium that I was going to toss out because one pane of glass was cracked that I converted into a nursery . All my aquarium light set ups for my boxes of water have dual bulbs (one , the proper spectrum for fish , the other for plants) and very expensive because I have planted freshwater set-ups . I changed the bulbs appropriate for AVs' and it has done a wonderful job .

The wife calls it my little greenhouse .

That's a great idea, I have done similar things. Love seeing others ideas too.
