During their vegetative stage, marijuana plants will need a lot of water and plenty of it. That being said, if you overwater your cannabis plants or don’t water them often enough, they may not be able to intake all the water you are giving them, which can result in stunted growth.
Water should be able to travel to the bottom of your plant’s roots, so make sure you are giving them enough H2O.
You will want to check your soil every day during the vegetative stage and water it if necessary. It would help if you didn’t leave your plants in a tray of water, as this can lead to root rot.
When you are checking your soil, make sure that the top inch or two has dried out before watering it again. This will ensure that your roots are not sitting in water for too long.
Watering frequency is another vital aspect of safely growing cannabis plants indoors, especially during the vegetative stage.
The average cannabis plant needs about 1 to 2 gallons of water per day, so make sure you give each plant enough H2O to grow healthy and strong.
Ensure all the water penetrates down to your plant’s roots without leaving any puddles behind because you are giving your plants too much water. Also, ensure you are not underwatering your plants either because this will also result in stunted growth.
How often you will need water during the vegetative stage of growing marijuana plants indoors depends on many factors. Excessive heat or direct sunlight may reduce the amount of water your plants can intake, so be prepared to water your plants more often if this is the case.
Light penetration will also affect how often you need to water your plants. If you have a lot of light penetrating down your plant’s roots, check on them daily and give them enough H2O so that it does not dry out.
Your marijuana garden may need more or less water during the flowering stage, but you will still want to check on your plants daily to ensure they are getting enough H2O. If your plants are growing slowly and not producing many flowers, then that is a sign that they are not getting enough H20. If this happens, water them more often, and they should start growing again.
During the flowering stage, your plants will need much less water. The average cannabis plant drinking 1 to 2 gallons of water per day in the vegetative stage is reduced to about a gallon a week during their flowering stage. If you use a well-aerated soil mix during the flowering stage, you will be able to water your plants every other day or even less.
Depending on how often you water and the temperature of your grow area, the soil may dry out completely between each watering during the flowering stage. This is okay as long as you are following all of our tips for growing in soil indoors. After all, cannabis plants can adapt to a wide variety of growing environments.
Mixing up your soil mix every couple of weeks will also make sure that the nutrients and bacteria in the soil continue to stay fresh and active. This ensures that your plants receive all the nutrients they need for healthy growth. Just take some of the old earth out and replace it with new soil.
You will want to continue adding nutrients like you did when your cannabis plants were in the vegetative stage if you are not giving them enough H2O for them to intake. If your soil is drying out too quickly, ensure watering more often and using a well-aerated potting mix to water less frequently.
If you are having issues with the temperature of your grow area dropping too low, then you will want to use a soil mix with more perlite for them not to dry out so quickly. This provides added insulation and helps prevent your plants from getting cold.
When growing cannabis in hydroponics, a nutrient lockout is never an issue because the roots are sitting in a small amount of nutrient water constantly being provided.
