Plants look very healthy, both already started to flower.
Mineral one have bigger leafs but also more space between nodes, mineral one is also 2 cm taller :P
Looking forward to see those summer buds.
Looks like they are having a great start.
I wouldn’t put those glasses over your seedling, you can get fungus on your seedling and it could die. Let them out in the wind, makes them strong an resiliant.
Good luck. 👍
