Red Californian earthworm is extremely grateful animal for breeding. Through feeding this earthworm turns organic waste into high quality organic fertilizer. Food for worms is varied: cow, horse, goat, sheep, rabbit manure etc. In addition to manure, worms are fed with the old paper, cardboard, leaves, sawdust, straw and other waste from agriculture. The remains of the human food supply are also very good food for earthworms. All the food for the earthworms must be chop up and moisturized because the earthworms do not have teeth, thus they feed through suction of food. Also food for earthworms must be neutral reaction (pH: 6.8 - 7.2).

Californian red earthworms, or Red hybrid, through long selections has acquired truly amazing properties and characteristics that allow the cultivation of these species as domesticated animals. Although small in size, 6 to 10 cm and weighs barely one gram, through incredible pace of reproduction it creates amount of protein mass, that no other animal or plant species is able to produce. Quality of Red hybrids "meat" by its ingredients is equal to veal meat and is well above commercial types of meat. According to Michael scale for measuring the biological value of meat, Red hybrids meet is marked with 61.3. (for example other type of meat: veal - 62, fish meat - 55, commercially meat from 48 to 50 and soybeans - 36).

Lumbriculture or earthworm breeding is growing rapidly in the world and is directed in two ways, each of which may be potentiated in comparison to the other one. The first is the growing of earthworms for "meat" - low price food with high protein composition for chicken fattening, fish, pigs or for processing into protein flour, which is excellent addition to fattening cattle. The second objective / benefit is that earthworms, through feeding with organic debris, excrete the finest humus rich with minerals, vitamins and micro-organisms, that is many times more efficient than the most complex known chemical and natural fertilizers. The essence is that from the food that earthworms eat and pass through its digestive tract, creates fertilizers of maximum concentrations and in the best form in terms of usability for plant cultures.
Californian earthworm is mostly grown for the production of earthworm humus and is able to digest as much food as itself weigh for a time period of 24 hours. Earthworms possess amazing power of reproduction, and after 90 days become sexually mature and begin mating.
Also, its ability to consume all types of organic waste and thus solving the problem of environmental pollution motivate farmers that, through using earthworms, solve degradation of waste from large livestock farms, industrial plants, sewage sludge etc.

Litter as standard means a volume of 100 x 200 x 25 cm of soil/humus and food with around 100,000 pieces of mature worms, youth wings and eggs. In such litter there is about 25,000 sexually mature earthworms, and the rest are youths, because the adult worms are intolerant if they are alone and it is preferable to keep them separately only when sorted for sale. Such a standard litter is ripe to be, every 90 days, divided into new litters or on every 30 days from the litter can be collected specimens of commercial size.

Californian earthworm can be grown in outdoor and indoor space, where care must be taken on a number of factors such as the temperature in the litter, humidity and PH value.
Optimal conditions for growing californian earthworms are:
Humidity 80-90% (min 60% max 90%)
A temperature of 15-20 C (min. 4C max 30C)
pH value 5-9
