This is an indoor planting project using LEDs, and some of the parts are derived from the Desktop Planting project. ( http://www.thingiverse.com/thing:1453839 ) Compared to Desktop Planting project, planting on racks can save a lot of space in an apartment, and are allowed to grow more and various plants indoor.

I use "chrome rack", for example: https://i5.walmartimages.com/asr/d19b3860-acdf-4d95-a94a-0a11c8eba52c_1.936a12ed4fa5ed4ddb4b9cf996bfca47.jpeg?odnHeight=450&odnWidth=450&odnBg=FFFFFF
The size of my rack is W = 30cm, L = 60cm as shown below
