It’s hard to get a measure on the grass but the longest sprout appears to be about 19.6 centimeters. The water level is 6.8 centimeters and clear. There’s still no algae growth sadly. We can see a lot of condensation in the top and around the aquarium level today.

Our grass is nearly 19 centimeter now. It’s hard to get an accurate measurement because the grass is curling on top. The water level is slightly lower at 6.7 centimeters and there’s still no algae growth. The water instead remains clear. Other than that there is lots of condensation happening with water droplets at the top and around the aquarium level.

The water level is about the same compared to the week before from what I can tell. From here on out I’ll be taking precise measurements to be more accurate. This week the water level is about 6.9 cm. There’s no algae growth on the water. However, we have two sprouts of plants; both about half a centimeter tall. The water is fairly clear and there is some condensation on the very top.

My partner Ethan built our bottle biome will I was absent. We have a terrarium on top with seeds that will hopeful sprout as time passes. On the bottom we have a small aquarium and a string that water may travel through by capillary action. I think we may see the water cycle occur in the contained setting and our plants will grow reusing the same water over and over again.

Thanks for joining me! Please follow along as I document my bottle biome.
