how to germ weed seeds

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.

Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).

THE ART OF GERMINATING CANNABIS SEEDS

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.

Timescales can vary, as it all depends on how ideal your germination environment is (see the golden rules above). Even the worst grower could make a seed germinate, but it may take a few weeks and, of course, increases the risk of a weaker plant.

Regardless of where you get your seeds from, it is best to give them a slight (and delicate) inspection before planting. Most of the time, all seeds will germinate; however, poor-quality seeds will produce a weaker plant. Unfortunately, that is something you will not find out until well into the vegetative and flowering stages.

Most plugs are dry blocks of (usually) coco fibre. Peat plugs are an interesting alternative, as these contain some initial nutrients to help the seedling along. After fully absorbing about 500ml of moisture, or 250ml of a root booster and another 250ml water, they slowly turn into a moist, soil-like plug. Grow plugs usually have a premade hole in which to place the seed. After sticking the seed in the top of the plug, cover it lightly with a little leftover plug fibre. It takes a few days at maximum before you see the first heads pop. As soon as the roots grow out of the bottom or the side of the plug, you can stick the entire plug, complete with its seedling, into your intended medium. These plugs make germination and the initial transplant a piece of cake.

The top layer is the perfect place to germinate cannabis seeds, as it dries out faster than the soil further down the pot. This makes it easier to ensure the right level of moisture for the seed to germinate. If it gets too wet, the seeds will rot in the soil. If it stays too dry, the plant will not be triggered to emerge from its shell. Again, it’s all about finding the perfect balance between too wet and too dry.

So there you have it: whichever method you chose, germination should now be underway. Remember that even the best seed banks work with organic, natural materials, so 100% germination rates can never be guaranteed. If you get your technique right, though, most or all of your seeds should germinate according to plan. Once your seeds have become seedlings, the next steps of your grow await. There’s a lot of choices to make from here to harvest time: indoor or outdoor, which spot to pick, what nutrients to use, and so on.

How To Germinate Cannabis Seeds in Plugs

This is the part where most growers (especially the hasty ones) sometimes lose a seed. Remember that you are handling a baby plant here. The vulnerable root is easily damaged during the transplant. If you don’t trust your steady hands, it might be better to choose another germinating method.

Last but not least on this list is the germination of cannabis seeds in special plugs. These plugs are available in various materials, especially designed for quick and efficient germination of cannabis seeds.

The best known way of germinating cannabis seeds is to put them on or between wet paper towels or cotton wool. This method exists in different varieties, as it’s not so much about the paper itself, but more about the absorbency of the material. It’s very easy to make sure the ‘medium’ doesn’t get too soggy and doesn’t dry out easily. If it does dry, you can effortlessly add a few drops of water to immediately re-moisten it.

After the root has sprouted and has gained a few millimetres in length, it’s time to transplant the seedling into its soil and put it under a light-source. As a rule, a small 1cm deep hole made with your fingertip should do. Gently pick up the seeds one by one, taking care not to touch the root. Use a clean pair of tweezers and don’t squeeze. Make sure that the roots don’t cling to the paper or cotton wool. Lovingly cover the seed with a little (loose) soil and add a few drops of water. Now, all you can do is wait whole the story continues below the surface. As soon as the seedling pops her head above the ground and green leaves emerge, she’ll needf light to continue growing.
