The Benefits Of Grow Tents

Grow tents have helped to revolutionize personal indoor growing due to their versatility and cost-effectiveness. Grow tents allow the user to create the ideal environment for various plants through the use of lights, fans, humidifiers, and air conditioners applied to the enclosed space in the grow tent.

With outdoor gardening, the types of plants that can be grown are largely determined by the weather. For instance, tomatoes require relatively warm environments to thrive. They would not grow well in winter when temperatures are cold and the elements are intense. Grow tents effectively eliminate weather limitations. Tomatoes grown in the controlled environment of a grow tent are only limited by how effectively the user can adjust the internal environment to the likes of their tomatoes.

Light is also an issue in outdoor environments. Plants which thrive in low-light environments may be scorched in areas along the equator. Conversely, plants which love light may be dwarfed by the low light provided in many areas of the world. Grow tents allow the grower to control how much or how little light reaches the plants, and when that light is applied.

When compared to simple indoor cultivation methods, grow tents also waste less light. This is due to the reflection of light created by the inside surface of grow tents. In many indoor growing environments, the sole source of light comes from lights hanging directly above the plants. In nature, after all, the sun moves across the sky, casting light on different areas of the plant.

Imperfect reflective surfaces, such as the walls of a grow tent, act to scatter the light rays they collect from above, delivering them to different areas below the canopy foliage through a process called diffuse reflection. This means more efficiency in light use, energy expenditure, and, ultimately, happier plants.

Beware The Nutrient Lockout

Whether growing in a soil medium or using a hydroponic system, everyone is looking to create the most delicious, appealing flowers and fruiting bodies that they can. From growing a butternut squash to win the prize at the county fair to growing tomatoes for home consumption, size matters in the hobbyist's grow tent. A common mistake made trying to achieve this size is to constantly push more and more nutrients into the growing medium, in hopes that the plants will use them.

In reality, this doesn't happen. In contrast to humans, plants can only eat what they need to grow. If there are 100 units of nitrogen in the soil, and the plant only needs ten, then 90 will remain in the soil. If 100 more units are added the next day, and the plant only eats 10, now 180 units remain. If this process continues, it can contribute to an issue known as nutrient lockout, as salts clog the roots of the plants, inhibiting their uptake.

The problem with nutrient lockout is that it can produce symptoms in plants which resemble nutrient deficiencies, leading growers to add more nutrients, causing further symptoms. The best way to eliminate nutrient lockout is to perform a flush. Saturate the growing medium with clean water, and then apply a small amount of organic fertilizers to avoid any nutrient deficiencies which can accompany flushes.

Which Lighting Is Best For A Grow Tent?

The best light for any plant is the Sun. Plants have adapted over millions of years to best draw energy from the light spectrum that the Sun produces. Because of this, the best grow light for any plant will be the light which best mimics this spectrum. As various plants are adapted to different ways of photosynthesizing light, they respond better to different visible light rays.

The ideal range for most plants is 4,000-6,000 Kelvin, which is the unit used to measure the color temperature of a light. The higher the number is, the more blue the light will appear, while the lower it is, the more red the light will appear. This can help mimic the actions of the Sun in the sky, as some plants thrive in the evening when sunlight is more red.

Fluorescent rays are good for growing small houseplants, but for full-light plants that need to be grown indoors, they will need the power and versatility delivered by HID or LED lights. These lights can often get to a color temperature of 6,500K or beyond, while still providing the lower spectrum rays plants need. These broad parameters allow plants to thrive both during blue light vegetative states and more red light flowering states.

LED grow lights offer a broad spectrum and produce less heat than HID lights, but they are less intense. LED lights are also particularly energy-efficient. HID lights like metal halide and high pressure sodium provide more distance and intensity than LEDs or fluorescents, but they produce a considerable amount of heat and cannot be used in unventilated growing areas. HPS bulbs are ideal for blooming, while MH bulbs are suited to vegetative growth. For this reason, many indoor growers use a combination of the two.
