Buyer’s Guide and FAQ


In this section, you will find easy guides to find out which LED light to choose and how to find a perfect one among many LED light for 4×4 grow tent reviews.

What to look for in the LED light for 4 x 4 grow tent:

What are you growing?

First of all, the LED lighting for tents depends on seedlings and greenery. Other important factors are the landing region, the characteristics of the tent, the distance from the lamp to the plant, the location of the plants, and shade-loving specimens. You should also select the appropriate shape of the lamp, providing the ability to adjust the duration of the glow.

Watts per foot

First, decide – how many plants can you fit in a 4×4 grow tent? After that, you need to calculate the correct number of LED lights to provide proper growth and vegetation.

  • A LED light for plant growth of 150W is enough for a greenhouse or tent of 2×2 ft;
  • 250W suits tents of 3×3 ft;
  • 400W is good for 4×4 ft;
  • 600W is enough for 7×7 ft;
  • 1000W will match an area of 8×8 ft.

Light spectrum and PAR

The choice of the spectrum depends on the stage of growth as well as the type of plant. For greenery and in general, for most crops, a properly selected combination of red and blue spectra is sufficient. For growing vegetables, it is better to additionally use orange, yellow, and green, or choose multispectral LEDs.

Just as humans need a balanced diet, plants also need balanced full-spectrum lighting. The quality of the light is just as important as the quantity. Plants are sensitive to light in about the same range as the human eye. This portion of the light spectrum is related to photosynthetically active radiation (PAR) in the spectral range of 400-700 nm.

Light intensity

The light intensity is determined not only by the characteristics of the luminaire but also by its location. The closer the light source is to the plants, the higher the illumination level, since the light is less scattered. Before installing lighting, you need to divide the plants into groups according to similar habitat requirements. This will provide the desired level of illumination for shade-loving, shade-tolerant, and light-loving plants. The distance between the lamp and the top of the plant should be at least 10 cm; otherwise, the plant may get burned.

LED grow light options

  1. Incandescent lamps. The cheapest and not recommended option for many reasons: they have a short lifespan, low light output (up to 17 Lm/W), and significant heat generation.
  2. Fluorescent (energy saving) lightning. It is better to choose this option and use it to highlight vegetation in the house, greenhouse, and directly in the aquarium.
  3. LED lights. LEDs are better for plant to grow tents with lights due to the fact that they consume a minimum amount of electricity and generate no heat. Also, there can be different spectrums of light radiation, which allows you to choose suitable LED lamps for your own type of plants in the tent.
