Phytolamps are specialized lamps for plants. The most popular and modern photo lamps – LED – have a number of advantages: they hardly heat up, do not affect the temperature in the grow box, do not require ballasts, turn on quickly, and serve for a long time. Nevertheless, other lamps for plant growing – sodium gas discharge lamps (HPS and DNaZ), fluorescent ones – have a number of advantages. Lamps for indoor, grow boxes, light mode of lamps, grinder weed, and other important issues – we will consider in this article.

What lamps to choose for indoor

Lamps for marijuana and other plants (in other words, phytolamps) differ from ordinary household lighting:

  • taken into account the color temperature (different lamps are designed for different stages of growth),
  • you can choose the type of lamp depending on the size of the room or grow box, the price, the needs of the grower, etc.

When choosing the type of indoor lamp, you need to focus on the area that you want to illuminate. Three basic types: ECL (fluorescent), HPS (sodium) and LED (light-emitting diode) is needed by the grower depending on the area to be lit.

When grown indoors in large areas (greenhouses, large rooms, etc.), sodium discharge lamps have a good effect. They get very hot and require additional control gear (ballasts for lamps – chokes, IZU – impulse ignition device), as well as a high-quality cooling and ventilation system, a capacitor.

Sodium Discharge Lamps (HPS) are considered standard for growers. But it is important to consider that they are better suited for lighting large areas: they can dry out plants in a grow box.

Fluorescent (ECL) lamps are designed for small areas: from 0.36 sq.m.

Light-emitting diode (LED) lamps are modern and environmentally friendly. The best phytolamps are LED:

  • do not heat up,
  • work without ballasts;
  • serve for a long time;
  • wide range of color temperatures;
  • suitable for lighting any area.

What lamps to choose for grow boxes

When choosing a lamp, start from the area of ​​the grow box: in large areas (from 0.8 sq.m.), ECL lamps are ineffective, and sodium and LED lamps to work best. If the area of ​​the grow box is small (0.35 square meters and below), ECL lamps are good, inexpensive and easy to use. Please note, however, that good ventilation and cooling is required when using fluorescent lamps in a grow box.

Sodium lamps can be used in both small and large areas. HPS lamps need ballasts, and they are not cheap. However, it is more convenient to work with ballast: in the Growpro section “ ballasts for lamps ”, for example, Epra SolisTek MATRIX SE / DE 1000W is presented:

  • with display,
  • timer,
  • light mode settings (the display itself is green, does not affect the light mode in the grow box),
  • settings of wattage (from 600w to 1100w),
  • makes 8 different start-up tests, for overvoltage protection and lamp test,
  • operates at a higher frequency than conventional ballasts (impulses about 80,000 times per second, and old electronic ballasts 50-60 times per second),
  • you can buy a control panel.

Dnaz lamps – high-pressure sodium mirror lamps – are similar to conventional lamps, but with an internal side mirror coating. Such a lamp:

  • does not lose reflective properties,
  • does not require the use of protective glasses,
  • not afraid of water,
  • works well in water mist conditions,
  • makes it possible to direct the flow of light,
  • increases illumination due to mirror coating in the absence of protective glass,
  • gives a significant reduction in installed power while maintaining illumination.

Light-emitting diode (LED) lamps are a modern and technological choice for a grow box. Growpro has a large selection of LEDs:

  • luminaires of different configurations,
  • cannabis lamp sets,
  • Phyto tape.

These lamps are more expensive, but they will last longer for the grower, and also do not affect the microclimate in the grow box, do not dry out or burn the plants, and consume little electricity.

Light mode of lamps

Light is necessary for cannabis, under its influence vital processes occur in plants, the main of which is photosynthesis: the formation of organic substances that are significant for the plant in the light, with the help of chlorophylls and carotenoids. Chlorophylls and carotenoids are photosynthetic pigments that convert energy through the absorption of blue and red light waves. Processes (not only photosynthesis, but also flowering, growth, fruiting) are more active if the plant is better illuminated, and the spectrum of light is important:

  • Blue spectrum – seed germination and planting, vegetation stage, stimulates cell division, and an increase in green mass.
  • Red spectrum – stimulation of flowering and fruiting (ripening rate, set of pineal mass), root development.
  • Green spectrum – development of leaves and stems, useful for close planting and high bushiness.
  • White light – supplementary lighting of plants, growing in conditions of a complete absence of daylight.

The spectrum of the lamp is also called color temperature (also called spectrophotometric or colorimetric temperature), measured in Kelvin (K). The grower sees these designations when choosing lamps on a site with phyto-lighting. Lamps are vital for marijuana:

  • 6400K (blue color),
  • 2700K (red).

It is also worth considering the power of the luminous flux (measured in lumens, Lm).

The Growpro grower store has LED, ESL, DNaT, DNaZ lamps of different color temperature and luminous flux, depending on the needs of the plants and the needs of the grower.
