Right Type of Light


Many first-time gardeners are simply unaware of all the possibilities that the market offers nowadays. There are different types of lights that are suitable for specific plants. For example, if you grow cannabis from the seed to the fully grown plant, you require the LED light of the full cycle. However, sometimes, you may need it for blooming and vegetative stages only.

  1. Single-channel light. It contains an on and off option. The model is rather simple. However, it costs less and can be easily arranged to the light you want to receive;
  2. Two-channel light. It has bloom and vegetative modes. There are several programming options. Usually, you may find these features in Advanced LED high-end models.

Size of the Grow Area


Some people believe that big wattage equals coverage of big spaces. It is not necessarily true. If you want to receive the most accurate measures, you have to find the Daily Light Integral or DLI or Photosynthetic Photon Flux Density or PPFD.

Here is a helpful table to calculate the watts per garden’s area:

  • 32 watts – 1 by 1;
  • 128 watts – 2 by 2;
  • 288 watts – 3 by 3;
  • 512 watts – 4 by 4;
  • 1152 watts – 6 by 6.
