It's Earth Day today so I wanted to do something that I've been meaning to for a while. I had hollowed out a lightbulb but never found a project for it and as I was sipping my coffee I realized that while 'America Runs on Dunkin' it also generates tons (literally) of garbage as we become increasing a single use society.

Another bit of insiration for this 'out with the old' project is that Home Depot is giving away 1million compact flouresent lightbulbs today in celebration of Earth Day. This old incandescent bulb was just burning up precious watts (60W vs an equivelent 9W CF bulb). Still I used a dead bulb for this project - no sense in breaking a working lightbulb.

I cut the bottom out of the DD cup to make a cradle for the light bulb to sit in. Hollowing out the lightbulb is a bit more involved but is pretty easy so long as you are careful.

The flower is growing in a 50-50 mix of inert media (pourous rocks for hydroponics) and potting soil. Much like building a ship in a bottle, most of the work of potting the flower was done with bamboo skewers inside the bulb.

That's really it. This was a fast project since the bulb was already hollowed out. I just had to drop in the moist soil, squeeze to flower into the bulb, and carefully bury the roots in the soil. Because its so hot in boston today the inside of the bulb quickly covered in condensation but I'm sure the plant likes the warm moist air in there.
