The amount of light needed by a cannabis plant would not be as much of an issue if the plant did not feel threatened by the presence of another plant. It is a mixture of outside factors that interact with the light quality. It’s important to understand that SARP isn’t solely about access to light. It can decide if SARP behavior starts to show. Of course, temperature and the timing of the growth cycle play a role in the phenomena as well so, the overall environment is still critical. This also means they are less likely to stretch when red spectrum HPS lights are used because they have enough. To reach light that is being stolen by a neighboring plant.Ī marijuana plant can sense when a neighboring plant is close due to less red in the light that is reflected off. Short for “shade avoidance response phenotype.’’ This is when a plant stretches To make sure you don’t see any issues with nutrients arise in your next grow, I have created a balanced nutrient package, specifically engineered for growing marijuana plants! One example of a strain that grows tall both indoors and outdoors is the tropical, landrace pure Sativa. Keep in mind, some plants just naturally grow taller than others. But if those seeds were made by a ‘’Willy-nilly’’ crossing from hybrid plants, their offspring will be so variable that it will be hard to know what to expect.

If a marijuana plant’s parents were originally grown indoors or if they promoted the growth of crowding plants, there is a chance that natural selection kept this trait in the seed’s genotype. Make sure you’re germinating your weed seeds properly. Here are just a few reasons why a seedling might stretch: Some are biological and others aren’t, however in all cases, the plant grows differently as a result. Many factors may cause a marijuana seedling to stretch.
