6 Things to Know Before You Order Weed Seed Online

1. Look for high germination rates & guarantees

High germination rates mean most of the seeds will grow into healthy plants. Many reputable seed banks also offer germination guarantees to refund your purchase if a certain percentage of your pot seeds don’t germinate.

This is an essential factor because a high germination rate means you’re more likely to get a good yield from your grow. The best seed banks offer guarantees because they’re confident that you’ll see strong cannabis plants from their seeds.

It’s always nice to have a guarantee!

2. Check for accurate strain information

Do they know their Gelato from their White Widow?

It’s vital to find cannabis seed banks that provide accurate strain information. The best seed banks will include information on the THC and CBD content and the indica/sativa ratio.

This information is crucial in helping you choose the right strain for your needs.

3. Positive customer reviews are always a good thing

When you’re looking for a quality seed bank, positive customer reviews should be one of your primary indicators. Look for banks that have been vetted by other growers and have a good reputation.

Third-party forums like Reddit, ResellerRatings, and TrustPilot are great – don’t trust the company’s own testimonials… they’re obviously biased.

Reputable seed banks will also have a customer service team that is responsive and helpful. Reviews should indicate that the team is knowledgeable and willing to go above and beyond to help their customers.

4. Check for seed banks that ship discreetly (“stealth shipping”)

Shipping is a huge factor when you buy marijuana seeds online. The most reputable seed banks will offer fast and discreet shipping to ensure your seeds arrive safely and on time.

Stealth is key when it comes to shipping cannabis seeds, so look for banks that use discreet packaging or “stealth shipping”.

You don’t want your seeds confiscated by customs!

Discreet shipping is when your marijuana seeds are hidden inside everyday objects such as DVD cases, birthday cards, and cheap children’s toys.

Some companies may also offer “guaranteed delivery” where they will refund you or send our free seeds if your previous order is confiscated in the mail.

5. Does this company offer advice and help?

The best cannabis seed banks like I Love Growing Marijuana will offer helpful guides and resources to help you grow your plants successfully.

Look for banks that provide step-by-step guides, how-to videos, and troubleshooting tips. It’s good to feel that they care about your success in growing cannabis plants.

6. How can you pay? Do they accept bitcoin and major credit cards?

Many seed banks offer the most accessible payment options when paying for your seeds. Look for places that accept major credit cards, PayPal, and cryptocurrency such as Bitcoin.

Many growers like to pay in Bitcoin or Cash because it’s hard to trace it back to you.

You should also consider places that offer discounts for bulk seed orders. This can save you a lot of money in the long run.

Autoflowering, Regular, or Feminized? How to Choose Which Pot Seeds to Grow

1. Decide on your desired effects

Before buying marijuana seeds, you need to decide what effects you want from your own plant.

Do you want a strain that will help you relax and de-stress? Or do you want a strain that will give you an energetic creative boost?

Are you into sweet, earthy flavors? Or do you prefer strains that taste like citrus or pine? It’s essential to buy a strain that you will enjoy.

There are thousands of different cannabis strains on the market, and each one provides its own unique effects. Do some research and figure out which strain is right for you.

2. Consider your level of weed-growing experience

If you’re a first-time grower, it’s crucial to buy easy-to-grow cannabis seeds. Autoflowering seeds are a great option for beginners, as they don’t require a lot of experience or knowledge to grow.

On the other hand, if you’re an experienced grower, you may want to buy feminized seeds or regular seeds that are more challenging to grow. These strains often have higher THC levels and can be more challenging to cultivate.

Most online seed banks will stock your strain of choice in multiple seed types.

3. Think about your grow space

Before buying cannabis seeds, you need to think about your grow space. Indoor growers will have different needs than outdoor growers. So make sure you purchase well-suited seeds for your particular grow space.

For example, if you’re growing indoors, you’ll want to buy seeds that don’t get too big. If you’re growing outdoors, buy seeds resistant to pests and diseases.

Don’t forget to take your climate into account too!

4. Check the THC and CBD levels

Not all cannabis strains are created equal. For example, some strains have high THC levels, while others have high CBD levels.

If you’re looking for a strain with potent psychoactive effects, buy seeds with high THC levels. If you’re looking for a strain with medicinal properties, buy seeds with high CBD levels.

5. Consider a strain’s unique growing needs

Some cannabis strains have unique growing needs. This could mean that the plant needs a lot of light or that the plant is more difficult to grow.

Do your research and make sure you buy a strain that you’re able to grow easily.

How to Germinate Cannabis Seeds

An in-depth guide on how to germinate cannabis seeds. Discover different techniques on how to germinate marijuana seeds to ensure a successful cannabis crop.

Everything has a beginning.

Cannabis seeds, like all seeds, must undergo the germination process before it can grow into a weed-yielding beauty.

Countless cannabis germination guides litter the internet. However, none go as in-depth as our seed germination tutorial. Read along to learn how to germinate marijuana seeds like a pro.

You’ll discover everything you need to know about the art of germinating marijuana seeds. From the necessary equipment to different germination methods and everything in between, we’ve got you covered.

The Chemistry Behind Cannabis Seed Germination

Cannabis seeds require the right conditions to sprout.

Without the proper temperature, moisture level, or oxygen saturation, weed seeds will not germinate. Although you can readily germinate seeds outdoors, nothing beats controlled germination indoors.

Let’s take a look at the three primary elements that influence the germination rates of marijuana seeds.

Water

Water is the key player in the process of germinating marijuana seeds.

The outer-layer of the cannabis seed acts as a protective casing that provides a two-fold defense — prevent damage to the inner embryo and prevent minimal moisture from premature germination.

However, if the marijuana seed is saturated with water, it will eventually absorb the moisture and kick-off the germination process.

Oxygen

Once the embryo activates through water saturation, it requires oxygen to jump-start the respiration process. Oxygen fuels respiration, which unlocks food stored within the embryo.

Energy

After the respiration process, the embryo consumes the food stores, which in turn produces energy. Energy is the necessary product that propels the germination stage onwards.

Warmth

Even if cannabis seeds have access to water, oxygen, and energy, it’s all for nothing unless it has access to warmth.

As long as cannabis seeds experience 72-78°F during the initial germination process — they’ll burst forth from the ground and spread their primordial leaves under the sun or artificial light.

The three most important elements for successful weed seed germination

Why It’s Important to Germinate Weed Seeds Indoors

At its core, the germination process lays the foundation of cannabis plants.

Overall, marijuana plants will underperform without proper germination techniques compared to those that experienced ideal conditions during the germination process. Therefore, it’s always best to harness an indoor environment when germinating marijuana seeds.

What to Look For Before Germinating Marijuana Seeds

Before you begin the germination process, there are a few things you must look for.

Let’s take a brief look at each.

Damaged Marijuana Seeds

Ordering feminized or autoflowering cannabis seeds online is the best way to acquire top-shelf genetics.

The seeds, however, may experience a few bumps on the road during the shipping process. With this in mind, you must look over each seed to ensure there isn’t any damage.

As long as each weed seed is undamaged, the germination process will be smooth.

The Cannabis Seed’s Age

Next, it’s a good idea to write down the date on each seed pack once received.

By doing so, you’ll have a clear understanding of a seeds’ age. Like all things, cannabis seeds lose their luster as the years go by. Cannabis seeds may remain viable for decades. However, germination rates decrease over time.

Therefore, you should only germinate seeds that are properly stored for a maximum of 6-months.

The Cannabis Seeds Color

Lastly, you must check the cannabis seed’s color.

Cannabis seeds come in different sizes and exhibit various markings across the outer seed coat. However, the seed’s color is an excellent indicator that represents seed maturity.

In other words, light green to pale white seeds are immature and are likely unviable. Therefore, always make sure that your cannabis seeds are light to dark brown color before germination.

Take a close look at the seeds that you receive for damage or discoloration

Should You Use a Seedling Heat Mat?

Many new cannabis cultivators ask if they should incorporate a seedling heat mat into the equation.

Although seedling heat mats are excellent tools to ensure fast germination, they are not always necessary. Seedling heat mats work by producing a gentle warmth that won’t rapidly dry cannabis seeds during the germination process.

However, they may be overkill if you utilize them during hot days, such as those during the summer months. Alternatively, they are essential during colder months during the winter. Therefore, you can choose to harness a seedling heat mat based on the time of year that you choose to germinate marijuana seeds.

Three Easy Methods To Germinate Cannabis Seeds Indoors

Now that you have a broad understanding of germinating marijuana seeds let’s get some weed seeds poppin‘ with a few different step-by-step tutorials.

You’ll have a better idea of which germination technique to choose once you’re done reading this section.

1. How to Germinate Marijuana Seeds in Soil in Five Easy Steps

If you want to germinate weed seeds au natural — there’s no better option than using soil.

Here’s a list of what you’ll need to germinate cannabis seeds in soil:

  • Feminized or autoflowering cannabis seeds
  • Eco-friendly “starting” container
  • Soil
  • Water
  • Label
  • Heat mat (optional)

As you can see, the list above isn’t extensive in the least. In other words, germinating marijuana seeds in soil is incredibly affordable.

Step One

First, fill an eco-friendly starting container with soil.

The golden rule? Don’t pack down the soil. Remember, the soil you choose must exhibit a loamy consistency. Hardpack soil does not allow proper water drainage and oxygen circulation, which, as you learned previously, are critical components for the seed germination process.

Furthermore, if you choose to use a heat mat, place the eco-friendly containers on top to warm the medium adequately.

Step Two

Label each container.

The last thing you want to do is forget what seed you placed into each container — especially if you’re germinating multiple cannabis strains at once.

Step Three

Now, it’s time to sow the cannabis seed.

Create a small hole that’s roughly 0.25-inches (6mm) deep. Gently place the seed inside the hole and cover it. It does not matter which direction you put the seed — believe us when we say that the seed and gravity will sort things out.

It’s important to note that each eco pot should contain a single cannabis seed.

Step Four

Gently pour a small amount of water into the area where you buried the cannabis seed.

At this point, you must ensure that the cannabis seed never dries out. Once the germination process begins — there’s no turning back. Therefore, allowing cannabis seeds to dry will guarantee inadequate germination or premature death.

Ultimately, you must monitor the soil and continuously apply water until the seed sprouts.

Step Five

The final step is patience.

The moment the seed is planted, most beginners ask: how long does it take to germinate cannabis seeds, or how can I germinate my seeds fast?

Healthy cannabis seeds typically break the surface within 2-4-days. Older seeds, however, may take upwards of 12-days to sprout.

The germination phase is an incredibly vulnerable moment for cannabis seeds. Therefore, Do notwe repeatdo not dig up the seed to “check on it.”

This is what you can expect after you successfully germinate your cannabis seeds in soil

2. How to Germinate Marijuana Seeds Using Paper Towels In Five Easy Steps

One of the most popular germination techniques is the paper towel method.

Here’s a list of what you’ll need for this low-budget method:

  • Feminized or autoflowering seeds
  • Dinner plate
  • Paper towels
  • Spray bottle
  • Labels
  • Heat mat (optional)

Now that you’ve gathered the necessary supplies let’s get crackin‘.

Step One

Place two to three sheets of paper towels on top of a clean dinner plate. If you decide to use a heat mat to increase the temperature, place it under the dinner plate.

Step Two

Label the dinner plate with the name of the cannabis strain of choice.

Step Three

Place up to 10-seeds per plate.

You must make sure that a minimum of 1-inch adequately separates the seeds.

Step Four

Spray water on the seeds until the paper towels are completely saturated. Once done, place a new layer of 2-3 paper towel sheets on top of the seeds. Use the spray bottle to soak the new paper towel addition.

Remember: the paper towels must always remain saturated with water. If allowed to dry, the cannabis seeds will fail to germinate.

Step Five

The germination process should occur within 24-48-hours. After 48-hours, gently peel back the upper paper towel section. If the seeds germinate, you will see cracked-open seeds with an emerging radicle.

At this point, it’s time to move the germinated seed to its new home with a pair of tweezers. This final step requires extreme care because the radicle is fragile, and if broken, the embryo within will die.

Be careful when you use the paper towel method and make sure to label each plate

3. How to Germinate Marijuana Seeds Using Rooting Cubes in Five Easy Steps

Germinating weed seeds with rooting cubes is the ideal method for beginners and professionals alike.

Overall, rooting cubes provide the ease of the paper towel method and the soil technique’s efficiency. Let’s take a look at everything you need to when germinating marijuana seeds with rooting cubes.

  • Feminized or autoflowering seeds
  • Rooting cubes
  • pH 6.0 water
  • Rooting tray
  • Labels
  • pH meter and pH up or down
  • Heat mat (optional)
Step One

First and foremost, place the rooting cubes in the rooting tray. If you decide to use a heat mat, place the tray on top.

Step Two

Next, label each rooting cube or tray with the appropriate name of each cannabis strain.

Step Three

Use a pH meter and pH solution to achieve a pH of 6.0.

The amount of water you pH depends on the number of rooting cubes. Start with one cup of water if you are germinating less than ten seeds.

Germination cubes require a pH of 6.0 because they are typically made from peat moss, rockwool, or other soilless-based mediums. Therefore, a pH of 6.0 will ensure the best possible results once the seed germinates.

Step Four

Each rooting cube is equipped with a pre-made hole.

Place one cannabis seed per hole. You may tear off a small piece of the substrate to cover the opening. Once done, saturate the rooting cube with pH 6.0 water.

You must make sure that the rooting cube never dries out. Remember, cannabis seeds must remain moist until they sprout to the surface.

Step Five

Once again, patience is the final step when you learn how to germinate cannabis seeds with rooting cubes. Overall, cannabis seeds may emerge from the rooting cube within 2-4-days. However, germination may take as long as 7-days.

There are a lot of rooting cubes to choose from, but the germination process remains the same

Eventually, however, you’ll notice that you have more than a few old cannabis seeds. Luckily for you — all is not lost.

Here’s our tried and true technique to give your old seeds a boost during the germination process.

Cannabis Seed Scarification

Scarring cannabis seeds is incredibly simple.

All you need is a nail file or a piece of sandpaper. Use the file or sandpaper across the surface of the seed in question. You do not need to use an immense amount of force, but instead, a few good scrapes to scar the seed’s outer shell will do.

The point of seed scarification is to allow water to penetrate the seed coating easily. By doing so, the embryo receives a jump start that initiates the germination process.

Once the seeds are scarred, you may choose one of the three above mentioned techniques to complete the germination process.

A few readily available tools to get your cannabis seed scarification done
