Best Strains to Grow Together

The cornerstone of successful multi-strain cultivation lies in choosing the right strains.

Strains should be more like dance partners than competitors, moving in sync through their growth cycles.

Opt for strains with similar flowering times, height profiles, and light requirements.

This harmony is crucial, whether you’re juxtaposing the quick flowering Indica with its compact structure against the taller, longer-flowering Sativa, or blending photoperiod strains with the time-independent autoflowering varieties.

Compatibility Matters

In the intricate dance of multi-strain cultivation, not every strain is suited to be your partner.

It’s vital to understand the subtle differences between Indica and Sativa strains, their photoperiod needs, and how autoflowering strains can fit into this complex puzzle.

Select strains that share a semblance of a growth timeline and environmental preference to ensure a synchronized and harmonious grow.


  • Variety is the Spice of Life: Cultivating multiple strains enriches your harvest with a diverse range of buds, each with its unique effects and flavors.
  • Cultivation Mastery: Tending to various strains hones your cultivation skills, as you learn to manage different growth patterns and needs.
  • Risk Mitigation: Growing multiple strains diversifies your chances of success. If one strain encounters issues, others may thrive, reducing the risk of a complete crop failure.


  • Juggling Act: Managing strains with different growth rates and heights can feel like a balancing act, demanding keen attention and adaptability.
  • Space and Resource Competition: Diverse strains can lead to competition for light and airflow, especially in crowded grow spaces.
  • Nutrient and Light Requirements: Different strains often have varying nutrient and light needs, making it challenging to create a one-size-fits-all environment.
  • Harvesting Hurdles: Different strains mean different harvest times. This requires careful planning and organization to ensure each strain is harvested at its peak.

How to Grow Different Strains Together: A Step by Step Guide

Growing multiple cannabis strains in a single room is like orchestrating a symphony with each plant playing a unique part.

This guide aims to harmonize these different elements, ensuring a smooth crescendo from seed to harvest.

1. Strain Selection

The first step is akin to casting characters for a play – choosing the right strains.

This choice is pivotal and should be informed by thorough research.

Focus on strains that share similar characteristics such as height, growth time, and nutrient needs.

For instance, pairing a fast-flowering Indica with a long-flowering Sativa might present challenges, whereas combining strains with analogous flowering weeks can synchronize your grow cycle.

When considering autoflowering varieties, remember they operate on a different timeline and may require a separate approach.

Key is to find strains that can coexist without outcompeting each other, ensuring a harmonious grow space.

2. Environment Control

Once you have your strains, the next step is to create an environment that caters to their collective needs.

This involves maintaining ideal temperature and humidity levels, crucial for plant health.

Cannabis thrives in temperatures between 68-77°F and humidity levels of 40-60%.

Adjust your room’s conditions using tools like thermometers and hygrometers, and employ humidifiers or dehumidifiers as necessary.

Lighting is another critical factor.

Ensure that your lighting setup provides adequate and equal distribution across the canopy, adjusting light heights to accommodate plants of varying sizes.

This balance is essential for optimal growth and development of each strain.

3. Cultivation Techniques

Cultivation techniques are where your skills truly shine.

Different strains might require distinct training and pruning methods.

Techniques like topping, low-stress training (LST), and the Screen of Green (ScrOG) method are invaluable for managing plant height and promoting even light distribution.

Nutrient management is equally crucial.

Begin with a baseline nutrient mix and adjust concentrations based on each strain’s response.

Use pH and EC meters to ensure nutrient solutions are within the optimal range.

Remember, each plant is an individual; what works for one might not work for another.

Regular monitoring and adjustment are key.

4. Harvesting

Harvesting is a critical phase where timing impacts quality.

Since different strains mature at different times, you may need to harvest them separately.

Labeling each plant or even using different colored zip ties can help in identifying and tracking their progress.

Pay close attention to the signs of maturity in each strain – the color of the trichomes and the state of the pistils are good indicators.

Harvesting each strain at its peak ensures the best possible quality and potency of your buds.

5. Continuous Learning and Adaptation

Finally, remember that growing multiple strains together is a continuous learning process.

Each grow cycle offers new insights and challenges, encouraging you to adapt and refine your techniques.

Keep a detailed cultivation journal, noting the growth patterns, challenges, and successes of each strain.

This documentation will be invaluable in future grows, allowing you to build upon your experience and become a more adept and versatile grower.

By following these steps and maintaining a keen eye for detail, you can successfully cultivate multiple cannabis strains in one grow room, enjoying the rich diversity and satisfaction it brings.

What to Avoid Doing

Common pitfalls in multi-strain cultivation:

  • Neglecting Individual Needs: Each strain has its unique requirements. Failing to cater to these can lead to suboptimal growth or even crop failure.
  • Overcrowding: Too many plants in a limited space can lead to issues like poor airflow, light blockage, and increased risk of diseases.
  • Inconsistent Environmental Control: Fluctuating temperatures and humidity levels can stress plants, especially when different strains have varying tolerances.
  • Mismanagement of Nutrients: Applying a uniform nutrient regimen without considering individual strain needs can lead to nutrient burn or deficiency.

Recommendations to avoid mistakes:

  • Monitor Each Strain Individually: Keep a close eye on each plant and adjust care as needed.
  • Space Management: Ensure each plant has enough room to grow without being overshadowed by its neighbors.
  • Stable Environment: Maintain consistent temperature and humidity levels suitable for all your strains.
  • Tailored Nutrient Plan: Customize your feeding schedule and nutrient concentrations for each strain.
