By Tom Vella and Sarah Farrar The indoor plants of the future will rely on indoor soil for growing and maintaining their structure and the plant’s health, according to the latest research.
Potting soil has become a popular choice among indoor gardeners and the quality of the soil used in a home is crucial for the health and well-being of the plant.
The National Institute of Agriculture and Forestry (NIFA) found that in some parts of Australia, soil is used for up to 50 per cent of indoor growing purposes.
But the NIFA also found that only a minority of households were using potting soils in their homes.
In some parts, the soil is only used for a small percentage of indoor grow-ops, such as in terraced gardens.
The NIFA said it was important that a good quality potting surface was used in all indoor grows to minimise the risk of soil erosion and other problems.
“The amount of soil that is used in an indoor growing space depends on a number of factors such as soil quality, moisture and temperature,” NIFA’s chief scientist Dr John Higginson said.
“These factors affect the size of the growing area and its ability to absorb nutrients.”
The NFA said the best indoor potty surface was one that has adequate drainage to minimised moisture loss.
“Pots have limited drainage so it is important that they are made of soil suitable for indoor grow, with adequate drainage,” Dr Higgenson said.
He said a good soil quality could be determined by looking at soil quality and the amount of moisture available.
“If a soil is poor or uneven, it will be difficult for the plant to maintain its structure and it will also be difficult to maintain water uptake and water balance,” Dr Vella said.
The good soil should be in a dry, well drained state and ideally have sufficient moisture to maintain the plant in a good condition for growth.
“A good soil can have the ability to provide some of the best yields,” Dr Farrars said.
But a good indoor pot is also important to ensure a proper air circulation and ensure a safe environment.
“Water flow can be reduced if the potting area is too wet and too warm,” Dr Renn said.
A well-mixed soil is essential for a good air circulation.
“To minimise air movement, there are a number practices that we recommend in the home,” Dr Jellison said.
These include keeping soil well aerated and moist and ensuring that a pot is made of the right type of soil and that it has adequate water drainage.
“In addition, a good aeration system should be kept in place to ensure air movement and humidity are high,” she said.
