Things to consider on how to germinate autoflowering seeds

Germination is the plant’s process of growing from a seed, then slowly into a seedling. Seed preparation, the time and planting manner, as well as the planting space and medium, are some of the basics to learn about the germination process. The process starts from a small seed until it ends when the sprouts start to bloom. Once this process is done and completed well, the autoflower plant has a higher chance of growing into a healthy one.

Different agents will have an effect on how to germinate autoflowering seeds and may be responsible for how the plant will turn and grow. First is the temperature. If the soil is extra cold or extremely hot for the plant, the seed may have a hard time growing. The recommended temperature must be more or less 25 degrees Celsius. The soil is where the plant will first take its root; hence, it is also needed to get the best possible soil for the plant. There are soils sold with pre-mixed nutrients already that can be helpful for the germination process. 

Water can also be a factor. Growers tend to make mistakes and easily over water the plants. The water should only be enough to dampen the soil and not make it dripping wet. Cleanliness is also necessary. Make sure all the tools are properly washed and sanitized to avoid contaminating the seeds with any germs. It is likewise advised not to touch the seed with bare hands unless the hands are clean. Use gloves instead.

Different ways on how to germinate autoflowering seeds

  • The first method on how to germinate autoflowering seeds will require water, a paper towel, and a clean plate or any tray. This lets the seeds stay in the damp area for a few days until the seeds are ready for planting. The first step is to soak the seeds with water for a few hours. After that, prepare the tray and the paper towel. Wet the paper towel before laying it on the tray. Make sure it is just damp and not dripping. Once the towels are in place, put the seeds on the damp towel. Provide sufficient space for each seed. Once done, you can wet other sheets of paper towel to cover the seeds. Then, place the tray at a mild temperature of at least twenty degrees Celsius and inside a dark place like a cabinet or cupboard.
    The temperature might affect the dampness of the towel, so make sure to spray water in order to maintain the level of moisture. This moisture will help activate the seed and start the germination process. Leave it for two days up to one week or until the seeds are two to three millimeters in size. Once the seeds are ready, it is now possible for them to be planted in the soil. Bury them a half or one inch below and position them in a way that the seed can easily grow and take roots.
  • The second method on how to germinate autoflowering seeds is letting the seed soak in water for a few days. This is easy. Just make sure the room temperature is more or less twenty degrees Celsius to let the autoflower seed germinate well. Get a cup or a clear glass and place the seeds in it. Store it in mild and dark places and check for any changes. After three to five days, there will be tiny roots growing out, and the seed will pop open. Once they are in the right size, you can now take them out and plant them in the soil.
  • The third and most commonly used method to germinate autoflowering seeds is to plant them directly in the soil. Although this is common, the possibilities of germination are lower compared to other means. The good part is, there won’t be any damages that may happen to the seed, unlike the first two methods. The key to getting this method done well is the quality of soil used. Make sure the soil is airy and light so the air can go inside freely, and the seed will have an easier time growing. There are available soils that work perfectly well when growing sensitive seeds. The soil with premixed nutrients is also good. Gently put the seeds in the soil and bury them about a centimeter deep, cover it with more soil, and gently tap them to secure. After four to ten days, sprouts will grow visible.


With the three different methods, the grower will have more ways to experiment to get the best method to germinate autoflowering seeds. It is even possible to do the three steps all together to compare which methods work the best. Knowing whichever is the best lies in the trial and error attempts done by the grower.

These methods are proven effective with advantages and a few disadvantages on the side. What matters most is how careful and meticulous you are when it comes to handling the seeds.

The autoflower germination process also takes time and days, so the growers need to be extra patient and enduring. The growers also need to keep their hands clean, especially when touching the seeds. It may look manageable, but growing marijuana plants can be tedious for some. To lift the burden, one needs to get a better view of what to do and what to expect to ready oneself from what they are about to experience. The germination process is the first part, and a lot of things could happen in the life cycle of an autoflower plant, yet knowing the methods to germinate autoflowering seeds is already one step towards achieving a goal.

  1. That should be enough lighting for 2 plants. Remember you should always keep your lights approximately 12 – 18 inches from your babies. Make sure you supply them with lots of air.

  2. Hello,
    I have a lighting question and hope you can help.
    I bought a LED panel 27.6cm square.
    169 LEDs
    Rated power 45W/75W
    Actual power 25W+-5%/35W+-5%.
    I was wondering if this is sufficient for feminized autoflower?
    And also if it’s sufficient for 2 plants?
    Thankyou in advance.
