The basics of an LED growing setup

Every indoor garden that grows well with LED lights shares the same few ingredients: a light that matches the space, a timer, a height that gives plants the right intensity, air that moves, and a routine of checking the plants. Get these right and the rest is detail.

  • A light that fits the space. See how many LED grow lights you need.
  • A timer. Plants thrive on a steady schedule, which is why we recommend a timer rather than the wall switch.
  • The right height. Too close scorches, too far stretches. See how far to hang LED grow lights from plants.
  • Airflow and temperature. Moving air strengthens stems and removes heat and humidity.
  • A routine. Look at your plants every day, because the leaves tell you whether the light is right.

One light for every stage

Plants move through stages: germination, seedling, vegetative growth, and for fruiting plants, flowering and fruiting. Traditional growers switched lamps as plants moved through those stages, using Metal Halide (MH) for vegging and High-Pressure Sodium (HPS) for flowering. The great thing about a full-spectrum LED is that there is no need to worry about switching. You change the intensity with a dimmer, not the light. See which stage of vegetable and fruit growth you can use LED lights at.

Where to grow

  • A shelf or a countertop. Perfect for seed starting and herbs.
  • A grow tent. A reflective, enclosed space that holds light, heat and humidity steady. See grow tent lighting setup.
  • A spare room, basement or closet. Good for tents or shelves, and out of reach of pets and young children.
  • A hydroponic setup. Growing in water instead of soil works well indoors. See LED grow lights for hydroponics.

Keep it safe

Lights, water and electricity share the same space in an indoor garden, so safety matters. Use lights with a suitable IP rating, keep connections off the floor and read LED grow light power and safety.
