To avoid problems, it is best to plant the seeds when the tap-root measures approximately 1cm, or 2cm at the most. This will make it much easier to transplant and we won’t harm the development of the roots, which can be expand into the new growing medium without setbacks.

In our article on how to germinate cannabis seeds we explain step by step what you must do to achieve successful germination. Today we will take a look at the main mistakes made during this process, some simple errors that, as we will see, can easily be solved. Let’s see where many growers fail to germinate their seeds, it’s a great way to learn what not to do if we want to make the most of our seeds.

Direct germination in soil

Hi, thanks for your contribution. Mandala Seeds give some helpful advice but they don’t have a monopoly on germination methods! In my 20 years germinating seeds I’ve tried all different methods and I’ve found good and bad in all of them. except for the methods using moist paper towels, I refuse to use it these days – I found that’s a great way to get mold problems and a really bad start to the plant’s life! That definitely is far too much humidity. as for ambient humidity, we don’t specify anything in this post. What we do say is that the medium in which the seeds are germinating should be at about 70% humidity for the best results. There’s nothing wrong with using a humidity dome or mini greenhouse, as long as you know when to start ventilating. of course if it’s kept sealed all the time then problems are bound to arise! These days I start all mine in a glass of water with a few drops of H202 and then once the seeds open (usually 24 hours) they get transferred to the substrate. As for the point down/point up debate, I think I’ll need to do a side-by-side comparison to settle this in my own mind. I’ve always planted them point downwards or on their side and I’ve yet to see any weird stuff like roots popping out of the surface, or doing a loop-the-loop before the seedling breaks the surface. But it’s clear that the debate needs to be settled so I’ll do an experiment and I’ll be happy to be proved wrong! EDIT: I’ve since germinated over 100 seeds as a test, 1/3 of them went in the soil with the point downwards, 1/3 sideways, and 1/3 with the point upwards. Most of the seedlings broke the surface at around the same time but it’s clear to see that the ones that I’m still waiting for are mostly those that went in with the point upwards. The next step has to be a test in a terrarium so I can actually see what’s going on but I’m almost ready to call complete BS on this “point upwards” theory, FWIW. Thanks again for your comment, all the best!

Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.

This article has a lot of nonsense in it. From Mandala Seeds: A #1 seed killer is a closed humidity dome/mini-greenhouse. Humidity domes are only required for rooting cuttings. Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot! Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%. Btw, seed should be planted with the pointed end UP, not down. Tap root ALWAYS goes up no matter how you place the seed. It's by the nature, goes against the gravity to create a support for itself so it can push the seed out. It you put it with the pointed end down it will have to make double turn loosing the precious energy stored in the seed.

Im starting to think its true, because after looking closely at a germinating seed, it down infact look like its curling towards the "top" of the seed casing.

Yea on my first grow i planted root up and they sprouted in less than 1 day. Now this is my second grow and i planted root down and they still havent sprouted and its been 3 days so now im worried

Dunno , i never put em in exactly perfect anyway. Anything will work really.

Marijuana seeds should be placed with the POINTED END UP into a prepared cannabis seeds germination bed or just good soil at a depth of 1/2 to 3/4 inch. The embryo tap root emerges from the pointed (stylar) end and the natural method of growth is for this root to make a turn and grow downward (see the illustration) This bend formed by the downward curve of the taproot is what emerges from the soil and the friction of dragging the cannabis seeds upward helps the new plant to loosen and cast off the seed case when it breaks through the surface. If the cannabis seeds are placed with the pointed end down, the embryo will be required to expend a great deal of its stored energy for twisting and turning to position the tap root when it realizes that it is heading the wrong way (see illustration of germinating marijuana seeds) The seedling will need this energy to exert the forces required to later lift its head (now enclosed by the two halves of the seed case) above the soil, cast off the seed case and then spread its two embryo leaves and begin the life-giving photosynthetic process. This is a critical stage in growth and carelessness in placing the marijuana seeds will exhaust even the most hearty seedling and result in a slow start and a feeble plant in later life. Cannabis seeds should be placed in a small hole at a depth of 1/2 to 3/4 inch. An excellent medium for germination is a mixture of rich humus and fine sand, such as the type used for aquariums. The soil needs a ph of 7.5 to 8.0 and should not be so moist that it sticks to your fingers. If the medium is too moist, the seeds will rot and ferment before they can sprout. A simple test for moisture is to stick a pencil into the soil and if soil adheres to it when removed, then it is too moist. Sort of like when you test a cake by sticking a straw into it to see if it is baked through to the middle. The ideal is not too moist, and not too dry – and be sure that the soil is well-drained. Research has shown that a soil temperature that is at, or slightly above, the air temperature promotes the best survival rates and growth.

A CUT and PASTE for you all I have read ssen and heard of both up and down
