What is passive sub-irrigation?

What is passive sub-irrigation?

Passive sub-irrigation is a type of hydroponic growing system where soil is replaced with water and nutrients suspended in solution. In passive sub-irrigation, the inert medium acts as a wick to carry water from a reservoir below the planting up to the plant’s roots.

What is the difference between active and passive hydroponics?

Hydroponic systems can be either active or passive. Active means that nutrient solutions will be moved, usually by a pump. Passive relies on a wick or the anchor of the growing media. Hydroponic systems are also characterized as recovery or non-recovery.

How efficient is sub irrigation?

Sub-Irrigation is also much more water efficient than OI. Water is delivered where it is needed for the crop rather than evaporating during spray or from the surface as with conventional application. It delivers only the amount needed to the root zone, at rates 1 to 4gpm.

Will peat moss wick water?

You should also avoid using topsoil or compost.” The basic idea here is that you’re constructing a mix that will effectively wick moisture to a vertical height of at least 14″ (peat moss or coir). However, that same mix must be porous so as to provide proper aeration to plant roots (perlite).

How does sub irrigation method work?

In agricultural production fields, subirrigation is an irrigation practice to control the water table at certain levels by elevating or lowering it. This is accomplished by artificial- ly adding water to the soil profile underground to moisten the crop root- zone for a determined period.

What is SIP gardening?

Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping. A SIP is any method of watering plants where the water is introduced from the bottom, allowing the water to soak upwards to the plant through capillary action.
