How To Make Your Own Plant Grow Box At Home

Indoors and outdoors have traditionally been the two approaches for growing plants. However, many gardeners choose to grow plants indoors since it allows them to control their cultivation.

When you cultivate your plants indoors, you have a variety of possibilities. Unfortunately, the most popular is also the most expensive. It involves purchasing various items such as grow tents, grow lights, inline duct fans, and other components and putting them together to develop your plant. Building your own grow box, on the other hand, is one of the most cost-effective ways to grow plants inside.

What Is A Grow Box?

A grow box is a self-contained enclosure in which plants can be grown. Growing boxes are completely enclosed, with their lighting and ventilation systems, and they use hydroponics as their growing medium. Even in urban areas where transplanting to larger patches of soil may not be practical, this type of regulated system allows gardeners to adapt to the surrounding factors and achieve maximum plant growth.

Garden centers and internet retailers sell pre-made grow boxes. With a few basic skills and the accompanying instructions, you can create a simple grow box at home.

How To Make A Grow Box

Before you begin building your grow box, you must first gather the necessary components. There are a variety of different solutions available to home gardeners. Look for them at indoor grow setups to discover one that fits your budget.

You’ll need the following items to make a cardboard grow box:

How To Make A Grow Box

  • A cardboard box that fits in your grow space
  • LED grow light
  • Two tiny fans
  • Box cutter
  • A roll of aluminum foil
  • A pencil
  • Velcro pads or magnets
  • Glue

Step 1: Prepare The Cardboard

First, clean your cardboard and measure the room to determine how many lights or fans you’ll use. Ensure the two long parts of the bottom of your box are visible from the inside; this will provide a lovely smooth and even surface to design on. Next, tape the bottom of your cardboard box together.

Use a box cutter to cut off each corner of one of the two remaining extended cardboard flaps to produce a curve shape. This will serve as your garden’s sign.

Step 2: Fix The Fans

If required, use box cutters to fit the fans into one of the cardboard box’s short sides. Both fans, one on top and one on the bottom, should be on the same side of the box. Ensure that one fan is blowing air in and the other is blowing air out. The fans provide ventilation inside your grow box; otherwise, your plants may suffer from suffocation. If you are uncertain of what to do, make sure to consult an expert. Hydroworld provides a wide range of indoor hydroponics systems and grow kits, ranging from the basic Autopot Hydropak, which is a self-contained grow kit that needs no electricity to function, to the Current Culture deep flow system with air pumps and high-powered water pumps.

Step 3: Fit The Aluminium foil

To fit the aluminum foil into the cardboard box, cut it to size. Then, please attach it to all sides of the cardboard box using glue and Velcro pads or magnets, leaving only the fan exposed. As a reflector, aluminum foil is used.

Step 4: Drill Holes

Using a punch tool or a screwdriver, make multiple drainage holes on the box’s bottom. A plastic bag can be used to line the box to keep it dry and extend its life, but drainage holes must be poked through the bag and out the bottom of the box.

Step 5: Get Your Grow Light Bulbs In Place

Many economic gardeners utilize a series of light bulbs for heat instead of investing in an expensive heating system. Because halogen lamps emit more heat than standard incandescent bulbs, they can be used at fewer wattages to get the same results. Although I’m not an electrician, you may learn more here about grow lights. These bulbs serve as the grow box’s sole source of heat.

Step 6: Add Soil, Seeds, and Water

To within 1 to 2 inches of the top, fill the box with light potting soil. To settle the soil, tap the box a couple of times. According to package guidelines, plant seeds or seedlings in the box, then decide how many plants to put in your grow box based on the plant spacing guidelines on the package.

Follow the watering instructions for the exact plant you chose to keep the soil evenly moist in your new grow box. Although the porous, fibrous texture of cardboard becomes wet when you water the soil, it dries fast, so you may need water more frequently than you would with plastic or ceramic grow boxes.

Now that you’ve finished building your grow box, you’ll need to store it somewhere safe and away from foot traffic. It must be a convenient location for you. Decide what to plant based on your zone’s planting timetable. When the topsoil dries out, remember to water your plants.
