  1. When it comes to growing cannabis in the vegetative stage there’s one golden rule: give your plants as much light as you can!

    The reason for this isn’t so much about the number of hours you’re giving your cannabis plants each day but rather, how much light they’re receiving overall during the entire growth cycle.

    Ideally, cannabis should receive between 18 and 24 hours of light each day during the vegetative stage. This ensures that it’s receiving adequate light to grow and thrive, yet enough darkness to rest, stay healthy and prepare for flowering.

    To get the most out of your light cycle, it’s best to set up a timer that will turn the lights on and off in a consistent schedule. For example, with an 18/6 light cycle, your plants will receive 18 hours of light and 6 hours of darkness each day. For a 20/4 cycle, the plants would receive 20 hours of light and 4 hours of darkness. Keep in mind that these are just general guidelines, and you should adjust the light cycle to your plants’ specific needs.

    In terms of light spectrum, cannabis prefers blue/white light known as “warmth” or “sunshine”. This light helps promote strong, vigorous vegetative growth, encouraging the plants to grow faster and bear more buds. For this reason, LEDs and T-5s are the preferred setup for indoor growing environments.

    You should also keep in mind that the number of hours of light the plants receive in a day doesn’t always have to be the same. To give your plants the maximum amount of light possible, you can switch up the length of the light cycle so that it may vary from day to day (while still adding up to the same amount of hours overall). This can help to avoid light burn and to spread the light more evenly throughout the day.

    It’s also important to remember that the environment where the plants are growing can play an important role in the growth process. During the vegetative stage, light intensity matters more than the hours of light received. For best results, make sure the environment is well ventilated and the light intensity is bright enough.

    Finally, keep in mind that you should never change the light cycle abruptly. This can cause the plants to go into shock and lose their vigor, so make sure to transition them slowly if you make any major changes to the light cycle.

    Overall, the ideal light cycle for cannabis’ vegetative stage is typically between 18 and 24 hours of light each day. However, when it comes to light intensity and spectrum, be sure to adjust the setup to your plants’ specific needs and try to spread the light evenly throughout the day. This will ensure your plants are getting the most out of their light and will help them grow strong and healthy.
