Plugs are a practical way to germinate cannabis seeds
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.
By planting cannabis seeds directly in their soil or coco – or whatever other medium you might be using – growers cause the minimal amount of stress for the plant. Direct planting also allows the taproot to immediately dive as deep into the ground as possible. Furthermore, its leaves can enjoy the light as soon as they emerge from the developing seed. This way the seedling can start its growth with a fair chance, providing you with a steady, high-yielding cannabis plant.
How To Germinate Cannabis Seeds in Plugs
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.
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.
Wet paper towels are probably the most common way of germinating cannabis seeds
Also, how often should I water my coco coir seedlings? The frequency of watering depends on the evaporation and the water supply in the COCO. A common rule is; one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again.
Likewise, people ask, how do you use coir seed starters?
When should I start giving my Coco nutrients?
For coconut coir pellets, plant no more than 2 seeds per pellet for small seeds and only one per pellet for larger seeds. If both seeds germinate, do not pull one out. Pinch off one of the seedlings at the base to remove. This will give the remaining seedling a chance to survive and thrive.
COIR SEED STARTER PELLETS (Pack 20) Ideal for growing your own seedlings or cuttings & then planting without any disruption to the roots. To use, simply place coir pellet in a tray of water (or seaweed solution) & leave for a couple of minutes until fully expanded.
Most coco coir growers like to add approximately 30% perlite to the mix for best results. Although a lot of growers are also mixing clay pebbles in at a similar ratio. With equally great results. So much so, that premixed blends of coco coir and clay pebbles can be found in some online grow stores.
Coco coir is more forgiving than most hydroponic mediums, but not quite as an effective buffer as soil. That being said, you absolutely can hand-water cannabis plants in coco coir as one would soil cultivated marijuana. Moreover, the grower can assess when to water by picking the pots up. Light and dry just as is the case with soil. That’s your cue to water.
WHAT IS COCO COIR?
After several weeks have passed, add the peat moss to equal parts organic potting soil and perlite. Thoroughly mix them in a large bucket. The perlite will help to aerate the mix and keep oxygen flowing through the soil.
If you have coco coir in brick form, make sure to purchase a high-quality brand. Every brick will be relatively uniform. When you add 4-5l of water and leave it to soak for about 30 minutes, a consistent 9-10l of medium will be produced from each brick. Simply add perlite and mix by hand in a good-sized bucket.
Low-grade coco coir bricks can sometimes be overdried. Occassionaly they can have odd sizes. Worse, some can be really tough to break down into usable growing medium. No matter how much water you add, bunk bricks won’t crumble easily.
