Greenhouse farming is a way of growing crops within sheltered covering by a transparent, or partially transparent, material. The main purpose of these kind of farming is to provide conditions favorable to the crops and to protecting it from rough and destructive weather conditions and pests.
Pro: Plants grown inside a greenhouse do not require pesticides and herbicides to prevent bugs or weeds from destroying them. This protects your produce from chemicals that could negatively affect your health and reduce crop yield.
Con: Growing plants indoors is much more expensive than on the outside because electricity needs are constantly increased due to artificial lights, heating systems, built-in facilities for irrigation, cooling systems (depending on climate), etc. The high cost can make it difficult for beginners without deep pockets or investors to break into the market successfully.
