Sub-irrigation System For Optimal Plant Growth

Consistent soil moisture is the key to plants growth. It is important to have the best irrigation system for a better outcome. The term sub-irrigation, in agriculture, is a method of irrigation where water is delivered directly to the plant roots zones from below the soil and absorbed upwards. Three basic types of sub-irrigation system are in general use for potted plants in greenhouses.

1. ebb-and-flow - bench-mounted enclosures holding pots are filled and then drained
2. trough - water is flowed through bench-mounted, slightly sloping enclosures containing pots
3. flooded-floor - special sloped concrete flooring is flooded and drained.

Many gardeners are using sub-irrigation system for containers for their plants because it can save time, water and effort. It is also called as the self-watering planter. It is commonly used in vegetable garden and mostly in indoor plants. It also plays a very important role during summer when the soil becomes dried up easily. To keep the the soil moisture on our plants, sub-irrigation system supply water to our plants.

For example, the self-watering window box from is sensible and easy to maintain and usually lightweight. Easy to set up, space, remove, drain, store and clean (inside and out) these reservoirs offer any old or new window box a whole new start without having to buy or invest in a newer and more expensive self watering window box. Other benefits of self-watering planters includes: a good solution for busy or 'forgetful' gardeners and can be handy for hard to get at planters, particularly hanging planters or baskets or planters at the back of big groupings.

Although self-watering planters or sub-irrigation system for containers are quite expensive than any other planters, but they do reduce the frequency of watering and make up extra cost in time-savings.
