Key Takeaways:

  • Transplanting clones from rockwool to soil promotes rapid and robust growth by providing more space for the roots.
  • Preparation involves hydrating clones with a diluted nutrient solution and exposing them to low-intensity fluorescent light.
  • The step-by-step transplantation process includes using well-drained soil, making a comfortable hole, and placing the clone in its rockwool cube gently.
  • Preserving the root system during transplant is crucial for a successful transition.
  • Aftercare involves gentle watering, avoiding waterlogging, and monitoring for potential transplant shock.

The Significance of Transplanting Clones

Clones, much like teenagers, have a rapid growth spurt that requires plenty of space.

You see, confined living spaces can lead to “root-bound” plants, causing slow growth and weakness.

On the other hand, providing roomy accommodation allows roots to spread out, promoting robust and speedy growth.

As wise horticulturist Colin Little from Oklahoma Clones once said, “It’s important to watch your clones carefully for the first few days after transplant to ensure you can catch issues before the plant is too shocked to fully recover.”

Preparing for Transplantation

Before the transplant relay begins, a good coach prepares his athletes.

Similarly, in our horticulture Olympics, we prepare by storing our clones temporarily.

Here, watering them with a heavily diluted nutrient solution and keeping them under low-intensity fluorescent light (preferably T12 or T8 bulbs) are the name of the game.

This is a fantastic way to ensure our green athletes are hydrated and energized before their soil migration.

Step-by-Step Transplantation Process

Now, the moment you’ve been waiting for, the step-by-step guide to transplanting clones from rockwool to soil:

  1. Preparing the Soil: Use well-drained soil, ideally a pre-mixed medium made with perlite, peat moss, and other beneficial substrates. Soil should be moist, but not soaking wet.
  2. Digging the Hole: Make a well in the soil large enough to comfortably accommodate the rockwool cube. Your green Olympian shouldn’t feel cramped in its new home.
  3. Transferring the Clone: With gentle hands (remember, you’re a coach, not a drill sergeant), place the clone, still in its rockwool cube, into the hole. The cube should be level with the soil surface, much like a swimmer poised for a dive at the pool’s edge.

Preserving the Root System

This is the high-pressure moment.

Just as a diver needs a flawless entry into water, your clone needs minimal disturbance to its root system.

Overpacking the soil around the stem should be avoided to ensure a smooth landing and transition for root system growth.

Watering and Initial Care

Once the clone is snug in its soil bed, gently water around the base.

This is like giving your clone a warm bath after a hard workout.

Avoid waterlogging, as this can cause “damping-off,” a fungal problem more daunting than it sounds.

Monitoring and Aftercare

Post-transplant, clones may go through a phase of transplant shock, where growth slows down.

Much like humans, plants too can be shocked by a sudden change in environment.

Keep a close eye on your clones, and make sure to follow the wise words of Colin Little.

Conclusion: Setting Clones up for Success

Transplanting cannabis clones from rockwool to soil is like a thrilling event in the Horticultural Olympics.

Our green athletes depend on us for their successful relocation.

But remember, you’re not just a coach.

You’re also the biggest cheerleader of your green Olympians.

So put on your gloves, shout out some motivating words, and guide your cannabis clones to a gold medal finish!


Rockwool clones are planted by first hydrating the rockwool cubes in a nutrient solution with a balanced pH.

Then, place your clone into the pre-cut hole in the rockwool cube.

Lastly, keep the clone under fluorescent light and maintain a moisture level in the rockwool cube to encourage root growth.

Before transplanting, clones should have well-developed root systems, ideally visible outside the rockwool cube.

This usually takes 1-2 weeks after the clone has been placed in the rockwool cube.
