u cut a bottle in half, use the botton to hold sponges in pices , , fill with water ,cover with a pice of cardbord, it could hold muisture as well , use the top of bottle as a cover the top and in the hole i shove a wet sponge that gradualy drips water and helps keep humidity... make holes in the cardbord and put cutting in the now made green house, later on i could add a air stone with pump... i triyed cloning in my fish tank but my fish fucking eat roots like noodles...lol decrease the humidity as days go by but the first week keep them moist... and no direct light , like 14 inches away from lightsz is good , also helps to leaven the fuck alone cus the more i look for roots the more you would break the darn lil roots , not to mention to keep the roots in darkness , i just use foil to wrap the bottle.
