27/02/2024 - Day 10 - Just water, once per week. First week after germination and both are in 12.5L pots with the growmix and 100mL water in both. Leaves of seed B fixed itself! They were repotted on day 7 and they started growing after their repotting 'shock' on day 8 again. Looking all healthy. Let's wait!
28/02/2024 - Soil of seed B dry as a bone for the top 3cm. Watered 200mL pure water around the sapling until the edge of the pot, making sure not to water too close to the sapling. Seed A soil is a bit wetter, but still watered 200mL to keep both balanced.
Details filled in (temps, size, etc) are of the end of the week.
