Simple:

3 plastic dishwashing tubs that are stackable ($ Store)
Perlite.
Package of Tikki wicks


Cut the bottom off one of the tubs. Drill holes for tikki wicks on another tub.

Bottom tub = Water supply
Middle Tub = Spacer (bottom cut out)
Top Tub = Insert Tikki into holes so that they touch the bottom of the 1st tub. then fill with perlite with the torches level with the perlite. Fill with perlite. Fill the bottom tub with about an inch of water and wait 24 hours. Insert clones and wait 2-3 weeks, misting twice a day.

I would also get a heat mat and a plastic dome.
