clones should be taken from the growing tip of a plant. they should contain at least two nodes. because the plants dont have their own roots yet,care must be taken to not let the cutting dry out, so keep them humid by using a dome over tem.its also easyier to get rot because of this high humidity enviroment,so use a very free draining medium or none at all.cut back large fan leaves,the just transpire too much water.you can cut a leaf in half by removing the tips with steralized scissors.folar feed a very diluted ballanced nute(grow+bloom+micro) if yellowing starts.leave the plant alone during while its trying to root, dont be pulling them out to inspect all the time have patience.the cuttings will either die bigger,or wilt and die so disturbing the root zone and removing the humidity dome 5 times a day must stop.i know its hard to do,lol.look at the top of the plant to see what the roots are doing.happy roots= new growth and getting bigger.use olivias cloning gel.be careful with heat mats,i used to use a propagation tray with no holes filled with about 2 inches of sand in between my mat and cutting tray to evenly distrobute the heat.their is los of differant systems that work.some of the best ive seen are: air pump and prop tray,no dome w/ bubble wand.the cuttings were placed in styrofoam 1'x3'x3' with a small hole on the middle and alowed to float around with the roots in the water. its pretty humid around the water,so no humidity dome was used.another way is just use rockwool cubes( no holes),and propagation trays with a dome.the only problem with this system is you have to watch the water level perfectly.too high and the rockwool gets too wet and they will rot, too low and they wont get enough water.when placing the rockwool cubes in the tray,use a tray with the right size 1' squares and make sure all the cubes are at the same depth in the tray,if some are higher than others they wont get any water.i cut a square off one corner to keep an eye on the water level and so i can add water without removing the cuttings.keep the water level 1/8-1/4 of a inch above the bottom of the rockwool cubes.take the corner square from the tray,put in a piece of rockwool and wet it, then slice the side open to see exactly where the bottom of the rockwool is.they dont go all the way to the bottom, mark the trays where this level and 1/4 inch above.now you have two lines,low and fill to make it easier.ebay search propagation tray with dome if you dont know what im talking about.they are black trays(clear dome) about $10.its hard at first, but
