Growth (also creature growth) typically refers to an increase of creatures in creature dwellings in towns. Growth occurs at the first day of each week (beyond the first). The amount of growth depends on several factors but mainly from the level of the creature; the growth reduces as the level of the creature increases.
Every creature type has a basic growth rate, which represents the weekly increase without any modifiers. The basic growth rate for creatures from level one to four (low-tier) depends on the creature type, but for levels five to seven (high-tier) the basic growth rate is three, two and one (repectively). However, Armageddon's Blade expansion introduced Conflux which growth rates for high-tier level creatures deviate from this rule.
Growth takes place at the first day of every week in every creature dwelling as well as in the external dwellings found on the Adventure Map. In town dwellings the new recruits are added (if any are left) to troops already available in the town, but with external dwellings the reservoir cannot exceed the number of basic growth rate. This means that if the troops are not hired from the external dwelling, no new recruits will be available which in a way leads to "losses".
Growth rate in towns can be increased with a Citadel, a Castle, or a town specific horde building. Also, grail buildings increase the growth. It should be noted, that Citadel, Castle and grail structures affect only to the basic growth rate. There are different horde buildings that can significantly affect the growth rate of the creature type. Every flagged external dwelling increase the growth rate of the same creature type (including the upgraded types) by one. Additionally, parts of legion artifacts (e.g Head of Legion) or Statue of Legion combination artifact can affect the growth.
Special weeks and months
At the beginning of each week or each month a special week or a special month can occur, which can significantly affect the growth of certain creatures. Essentially, special weeks increase a certain creature type's growth by +5, and special month doubles the basic growth rate for the first week of the month. A special effect of Deity of Fire – the grail building of inferno – is that every week is The Week of Imp, and population of Imps and/or Familiars are increased by 15 in addition to normal growth. External dwellings are not affected by these special weeks or months. Additionally, a special case is plague, which is on of special months and thus can only occur on the first day of the month.

Other meanings for growth
Growth for wandering stacks is 10% per week. If the stack begins with 15 creatures then next week the number is 16 (15+10%=16.5 rounded down). After two weeks count is 18 (16.5+10%=18.15) and in week it is 19 (18.15+10%=19.965) etc.
