Managing Mother Plant Canopy For Quality Cuttings

Mother Plant Canopy Management affects how often and how many cuttings can be taken from the mother plant. Cannabis Cloning Success Rate and mother plant management are interconnected. A well-managed mother plant has a high count of nodes with many uniform shoots. Greater quality shoots have a higher rooting success rate. Hence, it is advisable to maintain medium-sized, short and bushy mother plants.

Canopy Management For Optimal Mother Plants Health

Healthy mother plants are a prerequisite to healthy clones. There is a fine line between canopy management and mother plants health. Highly intensive cutting frequency and intensity of clone harvests from the mother plant may result in plant stress and root senescence, which results in a prolonged reduction in transpiration, water and nutrient uptake. Very intensive pruning in some cases may significantly stunt the mother plant resulting in slow biomass recovery or in severe cases may lead to the death of the plant. In stark contrast, low-intensity and low-frequency cutting harvesting may result in overgrown plants that may require additional maintenance. Thus, cutting frequency and intensity should be optimized to reduce the negative effects of pruning events.

Factors to Consider in Mother Plant Density Management

When choosing mother plant density several important considerations should be taken into account. Indeed, the costs of starting material and labour requirements are lower when growing mother plants at low density. However, at lower planting densities, there may be greater variance in cutting uniformity and quality. Overall, along with more difficult maintenance a low-density mother plant production model may cause major cultivation disruptions even when one single mother plant is lost.
To diversify production risks, and enable greater cutting uniformity and quality consistency higher mother plant density should be considered. Nevertheless, there are several important factors to consider when growing mother plants at higher density. Despite being more ergonomic for workers as the canopy height is more predictable there is a greater risk of disease incidence when the canopy becomes overgrown. Hence, a higher-density mother plant production model requires more consistent canopy management and greater material costs.

Managing the Lifecycle of Cannabis Mother Plants

Mother plants could remain vegetative and capable of generating vegetative cuttings through their entire lifecycle when a long photoperiod is maintained. However, as mother plants age reduction in vigor may lead to a decline in cutting consistency and quality. Furthermore, older mother stock plants may also be more susceptible to fungal, bacterial and viral infections. Therefore, mother plants should be proactively replaced on a regular basis. Mother Plant Turnover should be performed within 6 to 12 months or every 3 to 6 months if possible.
