autoflower germination method

The chamber can be used with any type of medium, Rockwool cubes, peat pellets, coco fiber, perlite, or even soil and they keep the best environment for sprouting seeds and the first days of the seedling.

When talking about germinating auto seeds, germinating in less-than-ideal conditions will decrease the chances of sprouting, so unlike growing cannabis in bad conditions, which will still grow but can affect the harvest, germinating in bad conditions can end up killing your seeds.

Scarification is a method used to make ridges on the seed to help water pass through, to do this properly, you will need a piece of sandpaper but you can improvise and do it with a matchbox.

Step 3

First of all, we need to understand the anatomy of a cannabis seed.

The cannabis seed has a dark brown, hard, and often striped, shell, this shell is what protects the insides which are extremely fragile.

But first of all, you need to know the best conditions to avoid these problems.

As you may have seen, the seed is made out of two halves and has a ridge around it, if your seeds are old, that ridge may end up hardening too much and the seed won’t sprout.

You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.

Before we jump straight into the germination methods, there are a couple of germination golden rules. For the best results, we recommend staying within these guidelines, no matter how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a sign that they need to do so.

After 3–5 days, the seeds will start to open, and you should see tiny white tips appear. Once these roots reach 2–3mm in length, use extreme care to transfer them from the water to pre-prepared soil pots.

PLANTING DIRECTLY INTO SOIL

Often overlooked, it is all too easy to assume that the vegetative and flowering stages of cannabis growth are the most critical parts of the plant’s life cycle. However, with the chance of failure high unless you know what you’re doing, poor planning when it comes to germination can make or break your next grow. Giving your cannabis seeds the best possible start on their journey to bulging buds is a surefire way to encourage a healthy and robust plant.

Three fundamental principles will trigger that first small taproot to appear: warmth, moisture, and darkness. With the promise of moisture, a single root will take shape before slowly developing into the cannabis plant we know and love. In the right conditions, seeds will begin to develop within 12–36 hours of moisture being introduced to them.

Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.

Usually, seeds stay valid for 3 to 5 years if stored properly but with every passing year the seed germination percentage drops and it is harder and harder for you to germinate them. In time the seedling inside the seed loses its moisture and starts to shrink getting weaker and weaker up to the point that it is no longer alive and no moisture levels can’t bring it back to life.

You should definitely avoid any nutrients at the germination process and first weeks of growth because the little seedling has a certain amount of nutrients inside the seed, and too many nutrients can halt its growth.

The last stress that can damage the newly sprouted tap root or seedling itself is nutrients. For the first days and weeks of cannabis growth, you need to supply only pure water with no salts and nutrients.

Advantages

If you are using this method you need to control your humidity and it should be at the 80 % level. You also need to control the temperature of the surrounding air because there is no buffer (soil/rockwool) that can protect the seed.

Autoflower marijuana seeds can germinate in a wide range of temperatures. The optimal temperature for the surrounding air is 27 degrees Celsius but a bit of variation won’t harm the germination rate.

Just take your autoflower cannabis seed and put it in a wet growing medium 2 to 3 times as deep as the width of the seed. That little plant will shoot its tap root down into the ground and with those seed leaves will try to find the light.

This method requires a lot more work than just putting seed into the ground. Basically there are more things that can go wrong.
