Hydro help

I'm looking to make a cheap and easy hyrdroponic or bubbleponic system....i have 18 total plants about 5 weeks old currently in soil but are in desperate need of a new home....small amount of space, anyone have any suggestions or help????

PotRoast has a great DWC thread here you need to read and study.
You can buy a KIT, like at www.stealthhydro.com
you can use 5 gallon buckets, with lids, and use grow cups and airstones.
You can DIY, there are tons of HOW Tos here at RIU.
