True Living Organics - The Ultimate Guide to Growing All-Natural Marijuana Indoors (2012)

There are almost as many ways to clone as there are ways to grow cannabis. I personally am a huge
fan of the aeroponic and bubble cloner methods. My friends have cloned in peat pots (Jiffy Pots)
successfully, and I have used perlite and vermiculite as well as Rockwool many times in the past. I
never have needed any gels, rooting hormones, or anything else apart from straight-up tap water. This
applies to aero, bubble, and all other forms of cloning I know of. Don’t believe the hype, mi amigos;
all you need here is water.
This is my favorite bulb for cloning
Rooting cannabis cuttings is fairly straightforward, and there is a ton of good information all over
the Internet and in the many growing books out there. I would recommend Greg Green’s Cannabis
Grow Bible for all general advice on growing that is not covered in this book, including how to root
cuttings. However, I will tell you this: you should always try to take your cuttings from the lower
branches if possible. How fast your cuttings will root is largely relative to how much nitrogen is
being stored in that cutting. Since nitrogen is a mobile nutrient (meaning it can freely move around in
the plant to wherever it is most needed) it would be in higher concentrations at the growing tip (or
tips) of the plant, closest to the lights. Some strains also tend to root much easier than others, so take
this into account as well.
