Don't throw away the leftover pericarp and teach you to make a nutrient solution for growing flowers, no yellow leaves, no rotten roots.

You can use leftover fruit, peel, egg shell, animal bones, add water, boil in the pot for 40 minutes instead of nutrient solution. The pot is not too good, it is best to do more at one time. You can also use soybeans, put them in a bottle and add water to expose them. After twenty days, it can replace the nutrient solution. However, it needs to be diluted before use.

1. Fruit, peel, eggshell, etc.

(1) Materials: a lot of materials are available. For example, leftover fruits, peels, oranges, bananas and apples are fine. You can also use eggshells, bones of various animals, leftover milk and rice. Rotten vegetable roots and leaves are also fine.

(2) method: put all the materials collected in a pot and cook for about 40 minutes. Then take the clear liquid above, which can be used instead of the nutrient solution.

(3) Note: these materials have a peculiar smell and are not easy to remove after cooking, so it is best not to use too good pots. In addition, it is better to make more at one time, and you can save it if you don't need it, so you don't have to do it often.

2. Soybeans exposed to water

(1) production steps: take out the right amount of soybeans and put them into a glass cup. Add water, to the right amount, not too slow, need to leave part of the space. Then, place the cup in the sun. After two or three days, we can observe a lot of gas coming out of soybeans. After about twenty days, the water will become very muddy. At this point, it's almost time. This water can be used instead of nutrient solution, the effect is very good, and natural pollution-free.

(2) Note: these water can not directly irrigate the plant, it may burn out the plant. It needs to be diluted and a large amount of water is added.
