all you need is a tote (not a clear one) the size depends on the amount of clone you need but a 10gal is fine
and an air pump the kind used in fish tanks you can get this at walmart $12
and an air stone the long blue one is gr8 get this at walmart the fish department less then $3
and an air tube used to connect the pump and stone also less then $3
fill tote with ph'd water
place in air stone and turn on pump ( dont put pump in water)
cut small holes in the lid with heavy duty box cutter
place in cutting (soon tobe clones) stems should be below the top of water, wait 3-10 days and they should root
the bubbles from the air stone supply oxygen to the root system or to make one. With this system rootgel is an option but wont hurt to use. Make sure the holes in lid are big enuff to pull out stem and root system when they are ready and all so find a way to support the stem of the clone while in the cloner
