The early stages of a cannabis plant’s life are critical for establishing a strong foundation and healthy growth.
Light plays a crucial role in this process, providing energy for photosynthesis and influencing plant development.
A good seedling light schedule is to provide it with 16 to 18 hours of light every day which gives them an extended photoperiod duration.
In this blog post, we will explore the ideal seedling light schedule for cannabis plants, discuss the recommended duration of light exposure, address concerns about excessive light, and provide guidelines for the optimal distance between grow lights and seedlings.

A typical seedling light schedule for cannabis plants involves providing 16 to 18 hours of light per day. This extended photoperiod helps mimic the conditions of the vegetative stage, promoting vigorous growth and reducing the time it takes for the seedlings to mature.
Continuous light exposure during the seedling stage encourages strong root development and minimizes the risk of stretching or elongation.
What Amount Of Time Should Cannabis Seedlings Be Under Grow Lights?
Providing 16 to 18 hours of light per day is recommended. During the early stages of growth, cannabis seedlings require a consistent light source to thrive. It’s best to keep a watchful eye on the seedlings and ensure you adjust the lighting when they grow into the next growth stage.
This ensures the seedlings receive sufficient energy for photosynthesis, which is crucial for healthy leaf development and the accumulation of vital nutrients. Maintaining a consistent light schedule also helps establish a predictable growth pattern.

While seedlings benefit from extended light exposure, it is possible to provide them with too much light. Extremely high light intensities can lead to stress, stunted growth, and leaf damage.
It’s important to strike a balance and avoid excessive light levels. Monitor the seedlings closely for signs of light stress, such as yellowing or bleaching of leaves, and adjust the light intensity accordingly.
How Close Should Grow Lights Be To Seedlings?
The distance between grow lights and seedlings is crucial for ensuring optimal light penetration without causing heat stress or light burn.
As a general guideline, maintain a distance of 24 to 36 inches between the grow lights and the top of the seedlings.
However, it’s essential to consider the specific light fixture, plant species, and light intensity. Regularly monitor the plants for signs of stress or stretching, and adjust the light distance if necessary.
Establishing the right seedling light schedule is crucial for the healthy growth and development of cannabis plants. Providing the right amount of light per day during the seedling stage helps promote robust growth.
However, avoiding excessive light levels is important, as they can lead to stress and stunted growth.
Maintaining an appropriate distance between the grow lights and seedlings ensures optimal light penetration without causing heat stress.
By following these guidelines, growers can create an ideal environment for their cannabis seedlings and set them on a path toward successful cultivation.
