5 Ways to Grow Indoor Plants

1. Lighting to Grow Indoor Plants

Lighting is an essential component to plant growth. The energy it provides enables the plant to undergo its normal metabolic processes. It allows the plant to make its own food and as well as store energy for future uses. There are two ways to provide lighting to your plants indoors: through window placement and by using grow lamps.

Window Sills are the most accessible way for sunlight to penetrate inside your space. The positioning of the window also determines how much sunlight you are likely to receive. So, you have to consider its actual requirements when looking for a spot near the windows.Vogek Adjustable Gooseneck Full-Spectrum Grow Lamp grow indoor plants

The south-facing window has the brightest sun all day. Meanwhile, the north-facing window receives the weakest light intensity. For most indoor houseplants, though, the east-facing window is the best choice. This gives you lots of less intense morning sunshine. Thus, perfect for growing plants with low to medium light requirements.

Nevertheless, there are also instances where exposure to windowsill may not be enough. Or, simply not an option. In such a case, the use of artificial lighting or grow lights is your best alternative. 

Grow lamps are a specialized type of bulbs that are designed to emit light waves that can support plant growth. It comes in varying intensities, color temperatures, wattages, bulb types, and others. Thus, this is not a one-size-fits-all kind of thing. You have to find the right fit for your plant’s lighting requirements.

The growing medium simply refers to the type of potting soil you use. Each variety of plant has its own preferred soil conditions depending on its needs. Nevertheless, most growers opt to use soilless mixtures for their indoor plants.Miracle-Gro Perlite

These components are combined in varying ratios to provide physical support to your plants. Furthermore, it also promotes good drainage, aeration, and also serves as a reservoir for nutrients

With the correct combo and ratio, the soil-less potting mix can give you the perfect soil substitute. The ideal environment it creates encourages the production of higher yield. Moreover, it is also least likely to harbor pests and even weeds.

When giving fertilizers, it is a must to follow the recommended dosage and frequency of the product’s manufacturer. In as much as possible, dilute the plant food accordingly to minimize the risk of burning your plant.

Plants have their own temperature and humidity requirements too. Some varieties sit well in a hot and humid environment. While others like to be on the cooler or dryer side. But generally, a range between 70°F to 75°F is the most optimum temperature for most plants.  As for the humidity, most types of houseplants thrive between 40% to 60% moisture level.Govee Digital Thermometer & Hygrometer grow indoor plants

On the contrary, you can use your central heaters to give the room more warmth if that’s what your plants need. On a different note, you can use a humidifier and dehumidifier devices to help you balance the relative humidity within the grow space.

For accurate monitoring, it is always a good idea for growers to install an indoor thermometer and hygrometer. This will help you measure the levels and at the same time, keep track of the changes. That way you will know how to adjust the temperature and humidity accordingly.
