the flask is not airtight or maybe the germinating seeds are not moistures properly.....

The huge rise in the quantity of water shows that CO2 is generated by fully germinating seeds during the respiration process.
In fact, the germinating seeds actually respire as well as produce CO2.
It is absorbed by the KOH solution.
It creates the vacuum in conical flask.
The overall air content present in bent glass tube fully moves into conical flask.
It pulls the water content in bend tube more.
