In the first part of this series, you familiarized yourself with the different types of pots available for your plants. Now the question is, why, how, and when should you transplant your cannabis?
In this installment, we explain why progressive transplanting is important, while offering insight into why various container sizes benefit certain growth stages. Finally, we’ll review some techniques for successfully transplanting cannabis.
Why Is Transplanting Important?
Some growers initially sow their seeds in large containers in order to bypass the transplanting process. The setback is that the roots will be suspended in a large amount of soil and may not absorb all of the moisture. This sitting moisture can then lead to root rot.
For this reason, most growers opt to start seedlings in smaller containers before gradually transplanting them into their “finishing pots.”
When growing cannabis in containers, the number one limitation for plant development lies with root expansion. Roots need to expand and develop in order for a plant to grow and flourish. Containers determine the amount of space available for roots to grow, and cannabis requires transplanting in order to reach its full potential.
Furthermore, when root systems outgrow their environment and do not have enough room to expand, it may become “root bound.” The symptoms of a root-bound plant include:
- Flimsy new growth
- Stunted flower production
- Stem discoloration (reddening)
- Nutrient sensitivity
- Nutrient deficiency
A plant that is root bound may also appear under-watered. If a plant requires watering once or more a day, this may mean a transplant is needed. Plants that continue to grow while root bound are at risk of growth deficiency and disease, and may die off.
Gradually moving plants from smaller containers to slightly larger ones will allow the roots to develop, while getting the most from their containers. When
