Cheap drainage material like gravel in NYC?

| Hi all, I have an indoor bed about 12 sq ft that I need to cover with drainage material before laying on the soil. What should I use that's cheap?
I had a wood palette laid down that basically raised the soil an inch off the ground so the water could drop through between the cracks of the palette.. but I don't want the treated wood chemicals/paint (it's painted) to leach into the soil. So alternative ideas like this are welcome.
I was thinking of just using plastic wrap on top of the palette to protect from leaching. |

| I've used the Styrofoam Packing material in the past. Light weight, good drainage. Usually easy to come by. Not sure though if the Styrofoam would leach any thing nasty to eatable plants. Lot of Styrofoam plates and coffee cups being use must be somewhat safe. |

| Thanks for the tip. http://www.puyallup.wsu.edu/~Linda%20Chalker-Scott/Horticultural%20Myths_files/Myths/Container%20drainage.pdf This makes sense. It looks like a 'drainage layer' is pointless.
I realize I never figured out drainage holes... I have no idea how to do this without raising the bed off of the ground.... |

| If you put down plastic and poke holes in it should work. Only thing you need is for the extra water to drain out and pull O2 into the soil. |
