Seeds germinated very quickly. 13 out of 14 have made it. They are now just under 2 weeks old and are growing beautifully!

Only 2 out of 6 seeds have sprouted. And only one of them grew. The other came only as a stalk. No leaf formation. Now I remember why I no longer ordered from Mr. Hanf, but from Zamnesia. It's just very annoying when the timing doesn't work out just because mr hanf mainly sells crappy seeds. Just don't write to me again. Response from Mr. Hanf:I'm sorry to hear that you weren't happy with the germination rate of your seeds. Unfortunately, with a sample of three seeds, it can happen that not all of them germinate. Germination rates can vary greatly with cannabis seeds and depend on many factors. Even with high-quality, fresh seeds, it is possible that some will not germinate. The germination rate of high-quality, fresh cannabis seeds is often in the range of 60-80% or even higher. However, with some seeds, the germination rate can be considerably lower. It is important to remember that the germination process is not only dependent on the quality of the seed. Other factors, such as correct seed storage, optimal germination conditions including the right humidity, temperature and light conditions, as well as the correct planting method, also play a crucial role.
