majklsoft Germinated in water (I forgot to adjust the pH, but it’s around 7.0, which is still acceptable). I took a bit of a risk and germinated only one seed — a true one-horse bet… or rather, one mare. This time, I decided to start in a solo cup, even though it’s generally recommended to begin in the final container. My reason was to have better visibility of root development and to reduce the risk of overwatering. The transparent solo cup is covered with a second white one to block light.
The medium is Biobizz Light Mix, supplemented with a locally produced Czech mycorrhizal inoculant.The seedling emerged from the soil after approximately 48–72 hours.
IIt’s freakin’ cold in there (18C), so I decided to buy a small heating mat for her — arriving next week.

majklsoft Are you like me and always end up with just one sock? I have a whole box full of incomplete pairs.
Well, I finally found a use for them 😄 And I think it’s a pretty neat tip for you guys:
Instead of covering a transparent solo cup with another non-transparent one, just cut the toe off a black sock and slip it over the cup. It blocks light, but compared to using a second cup, it allows better root oxygen exchange. As a bonus, it also helps keep our little ones warm during winter. Cozy AF.
I think the mycorrhizae have already kicked in, as the taproot was visible at the bottom around day 3–4, with secondary roots showing up shortly after. Overall, I’m impressed by how fast the roots are developing. On the other hand, the leafy part is definitely taking its time…

majklsoft Day 9 transplant. Didn’t want to risk getting rootbound — roots looked strong enough to hold the root ball together. Transplanted almost dry, then watered thoroughly in the final pot.
I avoided watering the center on purpose and focused on the outer zone to push the roots to search outward into fresh medium. So far, so good.
No signs of transplant shock at all — she immediately started stacking a new node. On day 13, I started very light LST, more like positioning than training. Within 12 hours, the top already corrected itself, which tells me she’s healthy and vigorous.
