tank, any random fishtank, size is your choice
lights, any random fixture that fits the tank and has plant bulbs (plant light bulbs that is, dont go and try to shove a gladiolus into the socket!
)
fan, go to Radio Shack, buy a PC fan that's a good size for your tank, get a power adapter, cut the plug off, strip both wires, and stick it into the fan's plug.
get some potted neps, stick em' in the tank, get some live sphagnum, put it all around the pots, get some
Drosera prolifera, put em' in the sphag, put the lights on the tank, hook up to a timer (unless you want to have to turn them on every morning, and off every night), plug in, and bam! you have a pretty cool setup!
just sit back, watch the neps pop pitcer after pitcher, trim em' when the vines get too high, and just let the dews go crazy! i love the look of ferral drosera in live sphag for the landscaping of terrariums! and anytime the water level gets too low, add some distilled water.
oh, and dont forget to send me some of those nep cuttings!
