Germinate Marijuana Seeds
We kind of view this as unnecessary, but have added it in because many people swear by it. The theory is that by weakening the tough hull, it makes it easier for the tender seed to emerge. Some gardeners use a nail file to put a small nick in the marijuana seed; others use sandpaper to thin and scratch the hull.
Peat pellets or Jiffy pots and Rapid rooters
These can be found at most garden centers in home improvement or large department stores such as Home Depot, Lowes, Walmart, etc. These are thin wafers filled with peat (Jiffy Pots) or composted bark (Rapid Rooter) and a fabric outer layer that plump up considerable when wet and only cost about 10 cents apiece when bought in bulk though most are sold with a plastic humidity dome. From experience, these are the most foolproof method we have yet to use and have a high success rate. Simply wet the wafer and after it expands, push the marijuana seed in the center just until it is no longer visible. Then place the pot in the humidity dome and wait. Several days after the sprout appears, put the peat pot in the medium of your choice. Success can be high with this method. Rockwool cubes used for germination Rockwool is made out of spun melted rock or mineral fibers. They hold moisture quite easily and may be used in the same manner as peat pellets. Because they are slower to dry out, a humidity dome is usually not required. Starting the seed off in Rockwool is an excellent method of germinating marijuana seeds especially if you are going to use hydroponics for growing. One of the best characteristics of Rockwool is it contains a lot of air and is generally a nice start to your seeds life. Try and use 1 inch X 1 inch cubes, soak the cubes with water then squeeze a little excess water out, place the seeds (sideways) into a small hole in the top, pinch the hole together or cover with more Rockwool, then place the Rockwool cubes in a tray container. You can fill the container with water later on and the Rockwool will suck it up using capillary action. Try and use good quality spring water, it can be the cheap stuff, or rain but it is better than water from the faucet which might be outside the pH required by marijuana. Place the tray in a warm dark spot to germinate. After a day or so you will see the seeds crack open and the roots take hold in the medium. You can then transplant the entire Rockwool cube over to the main hydroponic system.
How to look after marijuana seedlings
Your marijuana plant will start to grow very quickly after germination. It is very fragile when it is small and sometime growers put a humidity dome over the top of them which protects and keeps them warmer but make sure there are holes drilled into the dome so that some air can make it in. Keep the seedlings away from draughts and use a very diluted nutrient mix when watering. Pot it up to a bigger pot once it has established itself and filled the pot or container you started it in.

Final notes on marijuana seed germination:
No matter which method you use, the temperature requirement is the same. Optimal is about 75º to 80ºF (24º C to 26.8ºC). Going above 90º F (32.2º C) can damage the seedling. Seedlings may still germinate as low as 65º F (18.3º C), but will take longer. Germinating marijuana seeds is quite easy, so why do people struggle so? Too wet, too cool and too much handling are the main culprits. Many growers swear by the use of distilled or RO (reverse osmosis) filtered water. We have just about the hardest tap water in the USA, yet never have any problems. Use purified water if it makes you feel better, but personally we see no need to. If you are or want to be a serious grower, keep different weed strains separate from each other. Be sure to label your seeds with which strain and date before you start germination.
How To Germinate Cannabis Seeds: A Step-by-Step Guide
“It all starts with a seed.” Learning how to germinate cannabis seeds is essential to all future growing success. Properly popping beans puts you on the road to healthy plants and heavy harvests. But there are a few things to consider in order to master how to germinate cannabis seeds the right way.
Step 1: Choosing Seeds
First, you must decide on what seeds to grow and where to get them. Seek out trustworthy seed companies that have been around and have a track record of successful breeding. Take a look at our High Times Seed Bank Hall of Fame for a list of 50 of the most well-known and accomplished strain creators.
Don’t have seeds mailed to the location where you’re growing or planning to grow. Beginners might want to start with an indica-dominant strain that will stay small and stocky with a short flowering time.
Sativa-dominant strains tend to stretch more and have longer flowering times. If your seeds have been sitting around in storage for a while, check out these tips for germinating old seeds.
Step 2: Sprouting Seeds
Some people choose to use the moist paper towel method to germinate their seeds but I recommend just sowing them directly into the medium you plan to grow in. This reduces any stress the seedling will suffer through the transplanting process and secures the young plant firmly into your chosen mix.
Moist Paper Towel: Place seeds on a plate between two moistened paper towels. Put a plate on top to cover and within a couple of days, you should see the seed cracked open and a taproot emerging. Immediately and carefully (using tweezers) place your seed into your growing medium taproot down and water it in.
There’s nothing inherently wrong with using a moist paper towel, as long as you’re gentle with the emerging tap root and as long as you don’t let the taproot grow too long before planting. My belief is simply to start the plant in its own medium to reduce the likelihood of damaging the tender young roots and shoots.
Straight Into Medium: Poke a hole in your pre-moistened grow medium of choice. Drop your seed in about a quarter- to a half-inch deep. Cover the seed with more of your medium and tamp it down gently.
The important thing is to not plant too deeply and to keep the medium moist and warm for the best germination success rate. Clear plastic wrap placed over the top of the container helps maintain humidity. A heating mat underneath your plastic tray will increase your success rate as well.
Step 3: Seedling Care
Within a few days, you should see a minuscule green shoot emerging from the top of your medium. Immediately get your seedling under adequate grow lighting. Ideally, for the strongest growth rate, you want Metal Halide (MH) lighting, but Fluorescent or LED (Light-Emitting Diode) lighting works fine and won’t produce as much heat.
No matter what lighting you choose, always remember not to keep your grow-light too high above your seedling as this will make it stretch to reach the light and leave your young plant looking long and lanky.Use a timer to make sure the lights are on for at least 18 hours per day. Learning how to germinate cannabis seeds also means treating the emerging seedlings with the proper care.
Temperature and Humidity: You never want your seedlings to dry out. Keep your medium moist but not soaking wet. The air in your grow space should be kept warm, between 70-75 degrees Fahrenheit and with a relative humidity between 50-60 percent.
Use a thermometer/hygrometer to keep track of these factors at all times. As your plant adapts to its new environment, you will see new foliage sprouting forth. Your plants are now well into their vegetative stage of plant growth.
Final Hit: How To Germinate Cannabis Seeds
Now that you know how to germinate cannabis seeds, you’re ready to begin the process of growing your own weed. Just remember, provide light, food and water to your plants when they need it and keep the environment within acceptable levels of temperature and humidity. You’ll avoid so many problems by simply maintaining the proper parameters.
One last tip: Remember to label your seeds, seedlings and clones to avoid confusion and costly mistakes. Now get growing!
Germinating Cannabis Seeds – Different Methods
A seed is a plant that’s waiting for the right conditions to germinate and grow. This post is designed to teach you how to germinate cannabis seeds as efficiently as possible in order to obtain successful results during this delicate phase.
Table of Contents
Cannabis seeds (or marijuana) germinate when they’re in the right conditions for successful growth. In nature, this process occurs on its own around springtime; moist soil begins to heat up with the increased sunlight and the inclination of the earth. We’re going to give a quick overview of the different methods used when it comes to germinating cannabis seeds.
Under these conditions, seeds germinate in soil protected from direct light and in an airy substrate. Once they’ve germinated they will begin to take root in the soil.
- Humidity: alongside heat, this activates seeds and softens the protective shell. Once the seed has germinated, it will need moisture to survive.
- Darkness: roots are incredibly light-sensitive, so they’ll need to be in the dark in order to guarantee germination.
- Heat: alongside humidity, heat activates seeds and indicates that the conditions are right to begin growing. It’s important to maintain temperatures between 20 and 26°C during the germination process.
- Oxygen: it’s important to periodically open the container in which you’re germinating your seeds in order to renew airflow and give your plants’ seeds more oxygen.
How to Germinate Cannabis Seeds
There are many different germination methods when it comes to cannabis seeds, from simple to complex processes. In this post we’re going to go through the most common methods used that, when done with a care, can be 100% effective.
Germinating Cannabis Seeds in Paper Towels
Germination in paper towels is La Huerta Grow Shop’s preferred and recommended method due to how efficient and easy it is, as well as being the cheapest method. Cannabis seeds ready to germinate in paper towels
- Absorbent paper towels (kitchen)
- Two plates or plastic, opaque Tupperware with a lid.
- Sprayer (optional.
- Latex gloves.
We highly recommend using latex gloves during the entire process in order to avoid accidental contamination via fungi or virus.
You can also use Germinator Pro to help you with this process; it comes with everything needed for the germination process, including a thermometer on top of the germinating container.
Steps to follow
- Place 6 – 8 paper towels on a plate or in your Tupperware, and pour in small amounts of mild water until they’re covered. Squeeze them softly until they’re moist but not soaking.
- Place the seeds on the paper towel “pillow”, keeping them a distance a apart so their roots don’t end up intertwining. The less you touch them with your hands, the better.
- Wet another 6 – 8 paper towels, squeeze to remove excess water and place them on top of your seeds.
- Place the second plate upside-down on top (or the Tupperware lid) in order to guarantee darkness. You can close the lid entirely or not, depending on how fast the paper dries. Keep in mind that you need to keep the paper towels moist until the last seed germinates. If you close the lid fully, open it once a day to make sure they get more air and to check if they’ve germinated.
- Place the seed container in a warm area without direct sunlight, keeping the temperature between 18 and 25°C. At La Huerta Grow Shop we’ve noticed that cannabis seed germinate faster and better when placed over very light heat sources like a router or on top of the fridge, which generate high enough temperatures to stimulate germination.
- Observe the process and maintain humidity. If the paper dries up, spray it again until it’s moist. Seeds don’t always germinate at the same time, so we recommend transplanting when the root is between 1 and 15 cm. If you leave germinated seeds in the container for too long, the root may grow too long and make them harder to handle. This initial root is highly delicate; we recommend using latex or plastic gloves.
- Transplant your seeds. You’ll need to wash the soil and make a hole as deep as the root; place the seed in with the root facing downwards. This allows the first two leaves to sprout above the surface of the substrate. The substrate should be moist – not soaked – until the plant grows its first pair of real leaves. During this delicate phase, the amount of moisture available is crucial; don’t let it dry out too much, but don’t over-water. We recommend using small amounts of water frequently.
*if you’re using a heater or heating mat, keep in mind that your seeds are in a container and not a flowerpot, so the heat may be excessive.
