This is a closed construction that is usually made of metal and plastic and features lighting, ventilation (optional), and climate control. That’s the most common solution for indoor harvesting when plants are cultivated by a single person.

This construction consists of multiple metal or plastic supports covered with light-proof fabric. This is a recommendable option for those who need a cost-efficient system that would be easy in installation. Inside, a tent can be covered with a reflective material (plastic covers have 94% reflectivity). Insulation blocks the sound and helps to sustain normal temperature. Most grow tents don’t have light and other equipment.

  • Grow Closets

Closets have pretty much the same shape, size and capacity as grow tents, but are made of different materials (usually are produced of a steel frame with aluminum walls).

  1. Sanitize your equipment (pipes, filters, reservoirs, etc) – that will eliminate the risk of pathogen development and root rotting. Get a few bottles of alcohol and hydrogen peroxide to clean equipment regularly.
  2. Use clean pH neutral water (ideal pH level is 7). If you can’t get such water, use reverse osmosis (RO) system to create optimal neutral conditions. Distilled water is also suitable.
  3. Sustain optimal temperature. Ideally, the water in the hydroponics system should be about  65 F (18 C) to prevent the formation of algae and provide enough nutrients. Air can be warmer – about 75 F (24 C).
  4. Ensure a normal humidity level in your indoor marijuana grow box: at early stage of development, plants need 60-70% humidity. In the blooming phase, it can be around 40%.
  5. Keep proper lighting. The type of lights depends on the available space for plants, the distance between them, and your budget. Light Emitting Diode (LED) fixtures are perfect for small boxes, but they are quite expensive.
  6. Keep the box ventilated properly – that helps to maintain a normal temperature and provide plants with carbon dioxide.
  7. Keep track of EC (Electrical conductivity) measure: it will tell you how much nutrients the circulating water has. For seedlings, EC level can be less than 1.3, for clones – as low as 0.5. While the plant is growing, you should gradually increase EC to 2.0, in the flowering stage – 2.5.
  8.  Make sure you get seeds from a reliable source. Even if you use the best weed grow box, the plant can only give what’s genetically predisposed.
  9. Don’t rely on luck – control the process of growing. Keep records, take care of temperatures, EC level, humidity, and other aspects to make informed decisions and provide plants with the best conditions.
