4. PLANTING INDOORS

To plant indoors you need: light (see chapter 6), water, food (see chapter 18), CO2 (see chapter 21), good circumstances and security measurements (see chapter 17). In this chapter we will only go into matters that are not handled in other articles.

To create good indoor circumstances is very difficult, especially when a sizable indoor plantation is built. Taking away the warmth generated by the lamps and taking away the overkill of moisture that is generated by lots of plants per square meter, high capacity ventilators are needed, possibly with a capacity up to 6000 M3 per hour. This kind of machinery needs big air-inlets and outlets that possibly can be visible and hear-able (a muffler has to be used) from outside. Furthermore, when temperatures are high and ventilation is working like crazy, the relative humidity often drops to 10 or 15%. This is killing for plants, especially for young plants that do not have a well developed root system. To prevent this, water machines can be used, but these machines create their own problems, water can ruin the carbon filter. I think it is best you solve these problems when they occur because every location has its own problems and possible solutions. Furthermore, it should be clear that a relatively small plantation also gives small problems (see chapter 5 about shelf growing). See chapter 23 and 24 for figures about circumstances, like temperature and humidity.
