In reference to the picture shared by you please refer to the below solutions/points
1: Please note the seeds have to be planted 0.5 inch below the soil level.
2: Please check the woolen wick - the purpose of the wick is to absorb sufficient water as required for the plant and to keep the soil moist.
In case the pre fitted wick is not absorbing the water as required, you can replace it with the spare one provided and fit the plastic cap on the wick , to keep your plants thriving.
3: To clean the reservoir you can rinse the bottom by filling water through either of the vents and then pouring the water from the other.
