Day 4: put the plant in her final pot, 15l, in which I put 6.5 pH soil mixed with 37g of Aptus All in One Pellets.
The seedling is growing well and does not seem to have suffered any stress from repotting.
From the fifth day after germination she also spends the night outdoors, when I cover her with the top of a bottle to shelter her a little.
@CanuckTaughtMe,
thanks for the vote of confidence, but I don't think I'm a good example: it's the first time I've reached the fourth week of cultivation and I'm making a lot of mistakes...
