A.J.'s cheap bastard cloning station. I never seem to use things as intended.
I use a scalpel to cut diagnoly in a down motion. It takes a bit to learn to pull as you cut else you crush, but not all that hard. You can buy scalpels for cheap at Tractor Supply or feed store. Often the curved blades are packaged with the handle as a "Castration Kit". The curved blades are sharp on the inside, makes slicing much easier if you havent done it before. Replace blades often.
I always go for a length that has at lease two nodes,slicing off each node to make more rooting points. Imediately after cutting, the cuts go into room temperature water I put out a day before. I -think- this eliminates chlorine from the water. I do NOT use pond or other natural water. Bad results there. Think bacteria.
Now this part sounds complicated but it is really easy. I have mortar trays from Lowes, they cost maybe five bucks. Into them I put a fish tank bubler, maybe 10 bucks from Walmart. Submersible fish tank heater maybe another 10 bucks. Solo cups with holes in the bottom and sterile potting soil go into the mortar trays, enough water into the tray so that the cups are submurged enough that the plant stems are under that level. It is usually 2 gallons after it soaks up into the medium. This has to sit for a day to soak up and I think to get rid of the chlorine.
I leave them in darkness for first 12 hours, then a single shop light. Too much light goofs things up. Oh and mist a couple times a day.
Poke hole into medium to make slot for stem. Stem comes out of the water, dip or roll in cloning / rooting solution. Drop into hole and push medium sideways to close hole. Do not shove stem in cause it pushes off the rooting compound. I used to be all fancy and use things like clone x, now I just use Miracle Grow or what ever they sell at Lowes at the time. Have tried it without rooting compound, peppers not so good, other plants no problem.
In two weeks, I drain the water or move them to another place. Used to be all anal about checking for roots. Now I just let it ride. If they did not take, they die. If they did take, they live. No reason to bother the roots.
I am 100% sure their are better ways. Even more sure those cloning machines will work better. I came up with this in my dirt poor days when just starting out. Not saying you should break the law, but the tech in the book Pot for Pennies is a great way to get any plants going on the cheap.
