Wow! We have four seedlings growing so far this week! Each is a different height but overall they all seem to be doing strong.
More condensation on the bottle and mostly concentrated on one side of the bottle
Upon getting the bottle our first observation was that there was quite a bit of condensation, much more than last week. Why is this? Could it be due to the time of day? Or a higher level of plant respiration inside the system? We're interested to see what the condensation will be like during week 4.
Plants growing at various heights
The plants range from barely popping out of the soil to about 5 cm. Two of the plants still have dirt nested on top of the growing plants. I wonder what impact that may have on the plants or when the dirt may fall back down.
Water level slightly lower but still pretty close to last week's level, and the snail is hanging on the string
Visible particles floating in water
Our snails seem to be just fine. One snail really seems to like hanging out on the string. We noticed that there were a lot more particles floating around in the water. That seems to be the main change in the water part of the system. The water level also seems to be slightly lower. I know plants take in water when they go through photosynthesis.
Dirt level decreased slightly
The dirt level seems to be slightly lower. Is it negligible? Will it keep changing and getting lower over time? Was the dirt just settling or did something in the system cause a change? The dirt seemed moist but not wet.
