- 2Indoor feminized varieties benefit from 3-4L pots for growth and 7L for flowering
- 3Outdoor feminized varieties require 20-30L pots for optimal yield
- 4Automatic varieties indoors thrive in 7-10L pots, while outdoors need 15-30L
- 5Mother plants require 20-30L round pots for long-term health
Selecting the right pot size is a crucial factor in cannabis cultivation, impacting both growth and yield. Whether growing cannabis for medical purposes in a controlled environment or cultivating hemp varieties, the choice of pot size can significantly influence the outcome. According to experts from Silent Seeds, the configuration of the growing space and the specific goals of the cultivation process determine the most suitable pot size
For indoor cultivation of feminized cannabis varieties in a 1m² area, it is recommended to use 3 to 4-liter pots during the growth phase, which typically lasts three weeks for most photoperiod-dependent strains. Transitioning to the flowering stage, 7-liter pots are suggested to provide the plants with more substrate, promoting vigorous growth. This setup allows for the accommodation of 8 to 10 plants in a grow tent, optimizing space and resources
In smaller growing spaces, such as an 80x80x160 cm area, maintaining 4-liter pots helps to manage plant height and growth. Utilizing strains with limited stretching is advisable in these conditions. For outdoor cultivation of feminized varieties, larger pots ranging from 20 to 30 liters are recommended to support substantial structural development and yield
When cultivating automatic cannabis varieties indoors, pots between 7 and 10 liters are optimal, as these plants are not transplanted between growth and flowering stages. This pot size offers a balanced plant-to-production ratio, allowing for 8 to 9 plants per square meter. Outdoors, larger pots between 15 and 30 liters can be used depending on cultivation goals, with certain strains like Moby Dick Auto and Critical+2.0 Auto delivering exceptional results in quality and productivity
For those preserving mother plants or maintaining a genetic collection, larger round pots of at least 20 liters, ideally 30 liters, are essential. These pots prevent root entanglement and support substrate renewal every six months. Proper pot size ensures good aeration, prevents nutrient accumulation, and supports the long-term health of valuable cannabis genetics
