Your plants also need water when you are not at home for a long time. With this thing,all troubles would be solved easily.
To keep the soil wet,you can make the WATER-BEAD full of water,then put it upside down on the soil.With the effect of
gravity,water would go down through the holes of plug slowly,and then make the penetration layer wet,as a result,the soil
would be humid for a period.If you need to leave for much long time,jiust put more WATER-BEADs.
