For using cow's manure it should be mixed with soil in 1/4 propotion. Then bury it and wait for month. Then you can grow on it.
Chiken's manure you should mix with water. Let it infuse for few days and then water your plants in veg stage.
20gr dry chicken manure for 1 liter of water to insist 2 days. Before use, dilute 10 liters of water per 1 liter of infusion. Carefully undiluted chicken infusion will ruin your plant!!!!
If you use manure sheep manure is good used after 3-4 months letting it dry out but the best I find is chicken manure. It must be dried out for over a year and mixed to let it break down so that it doesnt burn the plant. Chicken is best but long dry time before use. Then you have bat and worm castings which are quite expensive. but really good. For indoor I use a little worm castings in an organic mix of 70% soil 5% worm castings and 25% perlite. A lot of people use coco mix for a medium aswell but the ph could be unsettled and may need watering off before use.
