How to grow G13

At Bulk Genetics, we believe that growing G13 is a unique experience, full of rewards for those who choose to embark on this adventure. To ensure that every grower, whether novice or experienced, can enjoy the process and get the best results, we share with you our tips and opinions on how to carry out the cultivation of this legend.

The morphology of G13 reveals a plant of medium height, robust and resistant, capable of adapting to various climatic conditions, although it shows its maximum splendor under a controlled photoperiod. This hybrid vigor not only alludes to its physical strength, but also to its ability to resist pests and diseases, making its cultivation a task of medium difficulty, accessible to both the novice and the veteran grower in search of a rewarding challenge.

First, it is essential to pay attention to the growing environment. G13, with its hybrid vigor, adapts well to both indoors and outdoors, but loves spaces where it can breathe and stretch. Indoors, make sure you have an adequate ventilation system to keep fresh air circulating and control humidity. Outdoors, look for a location that offers protection from weather extremes and sufficient direct sunlight.

Nutrition plays a crucial role in the development of G13. A balanced fertilization regime will enhance its vigorous growth and the production of its coveted resinous buds. Don’t skimp on quality when it comes to soil and nutrients; your G13 will thank you in spades.

In terms of cultivation difficulty, we classify G13 as medium level. This means that, although some aspects of caring for these plants require attention and care, with a little dedication and following our recommendations, you should be able to handle it without problems. Patience is key, especially during its flowering period of 8 to 9 weeks, but we assure you that the wait is completely worth it.

Last but not least, it is crucial to pay attention to pruning and training your plants. Techniques such as topping and LST (Low Stress Training) can be very beneficial in increasing production and allowing light to penetrate more effectively to the lower areas of the plant.
