3rd week of bottle biome

When I checked my bottle biome, I was surprised that it grew up so fast. I saw white stuff in dirt which was roots. There was a lot of roots growing. Water went down by a little bit because string in the water sucked up the water to keep dirt moist. There was some part that didn’t have any plant it’s probably because when we were spreading the seeds it didn’t reach there. I hope it grows really high so it can reach the top of the bottle.
