Very nice concept indeed.....Very nice.

I question the following:

1. Why so many frickin plants in each container? Just playing the odds for germination?

2. THe mirror in the back...it needs to go. It will eat more light than it reflects.

3. What are you going to do to add more light? I think they are needing more....

4. What are your plans for when they get 5 feet tall and need 3X the light and room?

I think I might even look at this for something to build off of.....

Nice job
