Indoor cultivation is, as you can imagine, the most recent culture. It appeared about a century ago to be able to thwart the laws, prohibiting the cultivation, marketing and consumption of hemp.
Large indoor hemp crops are grown in huge sheds. The producer can have total control over production, ie over CO2, light (artificial with HPS, Led, neon or other lamps), temperature, humidity, PH and nutrients. Crops are therefore protected from bad weather and pests. However, if however there is an attack of pests such as mites or aphids, the producer will have more difficulty getting rid of them because there will be no auxiliary insects able to put an end to the pests without destroying CBD plants.
