How to Clone Weed in a Cup of Water (Easy!)

by Nebula Haze 

Did you know you can clone cannabis plants in a cup of water?

1. Cut off a longer stem.
2. Immediately put in water. 
3. Roots form in a few weeks.

Who doesn’t want a bunch of free cannabis plants when it’s this easy?

Leave your cup in a warm sunny spot, and wait several weeks for roots to form. Some clones take as little as 2 weeks, most have roots by 4 weeks, and I once had a clone that took 6+ weeks. Aeroponic cloning is faster, but more work and supplies.

Roots form in 2-4 weeks (stubborn clones may take 6 weeks)

Put a rooted clone in soil, coco, or hydro, and you’ve got a new free cannabis plant!

Each of these cuttings is an exact copy of the “mother” plant. As a result, you know that all these clones will grow pretty much the same as each other (and their mum). Cloning is also a great way to produce a lot of plants at once for basically free.

I always use clones for my side-by-side grow experiments.

If buying seeds is too expensive (and creating your own seeds isn't feasible), then cloning can make growing cannabis a lot more affordable. Plus, cloning via the "cup method" is easy and doesn't take much space, effort, or equipment.

This tutorial will teach you how to make rooted clones like this, in a cup of water.
