The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.
Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.
First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.

The paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.

Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.
When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.
After you are done filling the pot with soil, make a small hole for the germinated cannabis seed. Since the seedling is tiny, a clean pen or pencil can make the dimple the appropriate size. Place the writing tool on top of the soil and push it down to create the dimple. The depth of a hole matters for the growth of a weed seed.
The next step of planting a cannabis seed is to move it into a small hole. Gently pick up the plant and place it into the soil. Some growers prefer to use a clean pair of tweezers to transfer it over to the pot. It is critical not to squeeze too hard to prevent the germinated seed from getting hurt. Make sure to plant quickly to ensure the budding roots stay safe from excessive light.
Step 2 — Make a Small Dimple
Once you have the best pot or cup for your germinated seed, fill it with soil. After planting is done, the root system should always grow downward as the plant gets bigger. Therefore, you do not want to put in too little. The roots still need enough space to absorb nutrients.
It is important not to add extra nutrients to the soil to keep the plant healthy. The potting soil already comes with the necessary amount of minerals a cannabis seedling needs to grow. The young plant is vulnerable to a nutrient burn, which causes leaves to lose the meat it requires and turn brown or yellow
The best choice of soil for marijuana seeds is a light mix. The light mix does not have a high concentration of nutrients, which can be detrimental to a seedling’s health. Young plants do not need as many nutrients as mature ones.

If you’re reusing pots, be sure you wash them well before you use them.
Check out our latest tutorial video below about what to do with your seeds after they have started to germinate (when they’ve started to grow). Then keep scrolling for some tips and links to help you out! If you missed the first video on How to Successfully Start Seeds, be sure to check that out first, as it will get you started on growing a great garden – whatever your skill level.
Important note: when you do move your seedlings outside, you need to do something called “hardening off,” which is slowly exposing them to the conditions they will encounter in your garden.
Be sure to check your seed packet to see how long it should take your seeds to germinate. If no seedling has appeared by a few days later than expected, sow some new seeds.
There are several different options for how to fertilize your seedlings. The ones shown in the video are Sustane Compost Tea Bags and Alaska Fish Fertilizer 5-1-1 Concentrate 1 Quart
Seedlings need blue night and red light. Sunlight includes both. Red light stimulates the growth of leaves and flowers. Blue light regulates the growth/size of plants.
