Week 1 Vegetation:
Day 1: i plantet Nr. 1, 2 with the Taproot facing down, Nr. 3 horizontal and Nr. 4 with the Taproot facing up. Just doing some experimenting here.
Day 2: All plants are now above soil. So it doesnt seem to matter how you put the germinated seeds in the soil, except that Nr. 3 taking longer to get above soil. Nr. 3 seem to be mutant due to the 3 Seed-Leafs and 3 firstleafs. Lets see how things will evolve
