How to plant cannabis seeds in coco

Here are some additional nutrient suggestions for growing in coco coir:

10.) Repeat steps for second brick of coco coir & remaining half of perlite bag

Any bag of horticultural perlite from any manufacturer will work for this tutorial!

One batch makes about 5 gallons of potting mix, so it should easily fill a 5-gallon container. You could also use it to fill 3 x 2-gallon containers or 2 x 3-gallon containers, though in both cases you’ll be a little short.

Mother Earth Coco Mix is a highly recommended pre-made coco coir mix for growing cannabis. However, many coco mixes work great for growing marijuana, including FoxFarm Coco Loco and Roots Organics Coco Soilless Mix.

6.) Pull liner up and out, letting water drain .

Once your plants are in a good coco coir mix, you just add nutrients, water and light to get happy plants.

I have used Shultz, Espoma, Black Gold, and even Miracle-Gro brand perlite. Any 8-quart bag of perlite will work. Perlite can often be found in garden stores or the garden section of places like Home Depot and Lowes. I normally advise against all things Miracle-Gro, but their 8-quart bag of perlite is okay for this tutorial if you can’t find anything else. But remember, never use Miracle-Gro soil or their standard nutrient formula!

This is a tried and tested nutrient system for any type of hydroponic growing including coco coir. You can actually follow their nutrient schedule listed on the included nutrient schedule; it’s formulated for plants like cannabis.

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.

Growing your own weed is fairly easy, as explained in our article ‘All You Need For Growing Weed At Home‘. The hardest part for some growers though, is germinating their newly bought cannabis seeds. After all, the vulnerable seedlings are easily damaged. However, making sure your cannabis seeds survive germination is essential for a successful grow. In this blog, we highlight three tested methods that let anyone germinate cannabis seeds with minimal effort.

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.

For this method, simply prepare your medium by moisturizing it, again, without soaking the soil completely. Then take your flower pots and use your finger to make a small hole about 10-15mm deep in the top layer to put the seed in. Cover the seed up loosely and top it off with a little water. Be careful not to give too much at once though! A stream of water can cause the seed to travel further down the pot where it’s too moist – and too deep to travel back up again.

How To Germinate Cannabis Seeds In Soil

We cannot stress this enough. If you want good results, you are going to need good materials to start with. In case of growing cannabis, the first thing on that list are good cannabis seeds, of course. Besides high quality cannabis seeds all you need is some water, a warm environment (between 20-25 degrees Celsius) and – lack of – light to start germinating your future cannabis plants.

Another common method of germinating cannabis seeds, and probably the most natural one, is to stick the seeds directly in their intended medium: the soil. You can do this with or without soaking it in root stimulator for a few hours first.

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.

How To Germinate Cannabis Seeds, Step 1: Get Good Genetics

Cannabis seeds and sprouted seedlings require constant temperatures of around 20-25 degrees Celsius

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.
