I use styrofoam coffee cups. Holes punched in bottom of cup. Fill cup with vermiculite and run water slowly through cup to rinse. Place cup in small storage bin, pour ph'd water with a bit of peroxide in the bottom of storage bin. Poke hole in nice damp vermiculite for clone (use clone powder if you want) place clone in. Sometimes saran wrap over the top to keep some humidity in, but usually not. Just keep the water about 1/2 inch or so. Vermiculite will wick up the right amount for clone. Works for me.
