Cannabis Seedlings Growing Very Slow
Congratulations on your new seedlings! I can’t wait to see them grow into full-grown cannabis plants. There are a few things you can do to help ensure their success. First, make sure the soil mixture is moist but not too wet. Make sure it drains well so that the roots don’t rot from sitting in water for long periods of time. You should be able to see some brown spots in the potting soil if it’s too wet or has been sitting there for more than a day without being watered again.
You can also use some rooting hormone on each seedling to help it root faster and grow stronger off of its mother plant (or whatever other material you used). Finally, make sure there’s plenty of light available where they’re growing since they’ll need plenty of sun while they’re maturing into full-sized plants with large leaves that produce buds full of THC!
I just got some new seedlings.
I just got some new seedlings. They are about three weeks old and have not grown at all. What could be wrong?
The first thing to check is the temperature. Cannabis plants require warm temperatures (28-32 degrees Celsius) with high humidity levels, especially when they are young. It’s important to keep them in a well-lit area so that they receive enough light for photosynthesis and growth, but not so much that it becomes too hot or dry for them to grow properly.
I have used the same soil mixture I used last time which is a mixture of coir and perlite.

- The soil mixture is well aerated, has good drainage and retains moisture but it needs to be fertilized.
- It is also pH balanced
The seeds were soaked overnight in water before planting them two days ago.
Many people are aware that soaking cannabis seeds in water before planting them is an important part of the germination process. Water helps to break down the hard outer shell of the seed, making it easier for the embryo inside to absorb nutrients and begin growing. Soaking also speeds up germination time by breaking down other protective chemicals that prevent growth until conditions are right for growth (in this case, when soil temperatures are warmer). However, some growers have observed that their young plants grow slower than usual if they soak their seeds before planting them in soil.
Why does this happen?
The seedlings are growing very slowly right now.
If you’re new to growing cannabis, it’s important to know that seedlings grow much more slowly than mature plants. For example, if your seeds took 3 weeks to germinate and sprout into seedlings and now it has been a week since those seedlings appeared and they have not grown any taller at all (or even worse—they look sickly), this is normal.
You should be patient with the plant’s progress because any changes in its growth pattern can indicate issues with its health or environment. If you see something wrong with your plant or its roots, follow our troubleshooting guide for solutions on how to help get your cannabis back on track!
I am using a grow light about 18 inches above the seedlings for about 8 hours every day, room temperature of about 70F and humidity at about 50%.
You are using a grow light, which is used to simulate sunlight. They can be used to grow plants indoors, year-round, in any climate and also in any light conditions.
I have watered them twice with distilled water since planting.
Watering with distilled water is a good way to ensure that your seedlings don’t grow too fast and become leggy. If you use tap water to water your plant, chances are that the nutrient build-up in the soil will cause your seedling to grow too fast. Distilled water helps prevent this from happening.
However, it’s important not to use distilled water if your plant is already established and growing well. The reason for this is because using too much distilled water can actually kill your established plants by dehydrating them too quickly (especially if you have an indoor setup). Use tap water instead when watering plants that are already established since it contains more nutrients necessary for healthy growth than distilled does.
You could use some rooting hormone on each seedling to help it root faster and grow stronger.
It’s also possible that you could use some rooting hormone on each seedling to help it root faster and grow stronger.
There are several different types of rooting powder or gel available for purchase, so it’s best to consult the manufacturer’s instructions before using one. If you’re not sure whether your plant needs a particular type of hormone, ask your local gardening supply store employee for advice.
Some people will tell you that cannabis plants should never be given any kind of chemical treatment, but this simply isn’t true—there are many substances used by farmers and gardeners around the world that have been proven safe for humans and animals alike when used properly.
Seedling growth can be enhanced with proper care and using the correct nutrients.
- Soil mixture. The most common planting medium for cannabis seedlings is a mixture of peat moss and vermiculite, which helps regulate soil temperature and holds moisture.
- Light intensity and duration. Seedlings need at least 16/8 hours of light per day; as they grow you can reduce this to 12/12 hours in order to encourage more branching, which leads to larger yields once plants are mature enough for harvesting.
- Humidity should be 50% or higher during the daytime; humidity should drop during nighttime hours but not below 30%.
- Watering: Watering too little will cause wilting, while watering too much can cause root rot (a condition where roots become damaged or die off). Generally speaking, cannabis plants require about 1-2 inches (.3-.6 cm) of water per week at their roots for optimum growth—this is especially critical during germination!
If you’re wondering how to make your cannabis seedlings grow faster, it’s important to remember that they are fragile plants that need care and attention. If you’re growing indoors, make sure the temperature is correct and consistently monitored so that it doesn’t get too hot or too cold. If possible, try using an oscillating fan for ventilation when temperatures drop below 70 degrees Fahrenheit at night time; this helps keep humidity levels high enough for your plants to thrive in their first few weeks of life.
