+1 for Aeroponic Cloning as above.
Â
Aeroponic cloners are the easiest way to get a genetically identical plant, and may shorten production times etc. I've found that cloning gel is over-rated for aeroponic systems. All I use is PH'd water until roots form, and then slowly add rooting enhancers (Rootbastic, Rapid Root, etc), as well as a small amount of hydroponic fertilizer.
Â
I suggest learning to clone with tomatoes, as they are an easy plant to start with. Within a week you can have a tomato that is ready to plant and at 12" or more tall. Cloning works with quite a few different plants, so don't be afraid to try it out on other plants around the yard as well.

I use a Turboklone T24 with a 1 min on 3 min off timer. No problems with water temps with the addition of the timer.
