Dragon Squama self watering planters work great for when you go on vacation.Simply fill up the bottle and put them in your indoor or outdoor flower pots.Then you can go relax without having to worry about your plants.Average watering time is 5 - 7 days,depending on the dryness of your soil,humidity etc.We recommend testing your garden spikes before leaving on vacation for the most accurate watering time estimate. How the ceramic watering spikes work? The ceramic part will automatic water the soil.When the soil gets dry there would be gap left and then the spike will automatically gives out water until all gaps are filled.When the soil gets dry again,the water will be refilled.Through this way,the watering amount can be automatically adjusted to keep the soil properly moist.
