germination and selection of plants for sea of ​​green

Giving them "a bit of everything" will not make them super plants. Pick one product and stick with it, "Mykos" would be my choice. Giving them a mix of three or more mychos may in fact be detrimental due to the chance of one cancelling the others out. Also, your seedlings do not need a humidity dome, cannabis is not a rain forest plant and the high humidity and temps can cause fungal problems and stretching respectively. Your seedlings need good air exchange to grow properly and good air circulation to strengthen the fibres in their stems, two things that a humidity dome prevents. Some of them already seem stretched and weak and may not be a true representation of the plants genetic potential but more of a reflection on the sub optimal growing environment they are now living in.
