Datong can no longer tell the difference. He is sure that he has a certain status, but it is not the whole world of the lady. The lady seems to have her own world, her own circle, and even her own friends...
The lady's heart is so unpredictable now that Datong is still waiting for her to write the sign.
"Madam, do you need my help?" Datong asked as he approached the yard of the dye house.
"No, sir, you have been tired for a long day, please take a rest." Haitang's tenderness and considerateness made Datong feel that he was very clumsy and could not help his wife.
"But my husband, I really want to help." Datong said.
"Then go take care of Tiantian." Haitang said. He didn't want Datong to interfere in the dyeing workshop. Unless he was a very special man, why would ordinary men like to wander around in the dyeing vat.
"Datong, come here." His mother called him, and Datong passed by.
"Datong, aren't you happy to find another three wives and four concubines?" Datong's mother asked.
"Thank you for your understanding, mother," Datong said.
"Mom won't embarrass you anymore, but Haitang promised mom something. Haitang can't do it alone. Datong, you have to help." Mom added.
"The child should do his best and ask mother to give her orders." Datong didn't know what happened between mother-in-law and daughter-in-law. Mother suddenly changed her temper.
"Haitang promised my mother to give birth to a son for the Tian family, son, you have to work hard." After Datong's mother said this, she taught Datong something like a steel ring.
"What is this?" Datong didn't understand.
"Silly son, this is... oh, what do you think, mother, you want to think that a good sister gave it to me, saying it works. You can try it tonight." Datong mother's old face is rare.
Red once.
Datong is confused, what does this thing mean?
I put it away casually without paying much attention to it.
Haitang was not idle at night. Looking at the large and small earthen pots she bought, I am afraid that she will spend her time here tonight. If hydroponic plants want to take root and sprout quickly, they cannot just use water, but rely on nutrients.
.
There are nutrients in the soil that can be absorbed by plants. Chemicals must be synthesized and dissolved in water to provide the roots of plants with the same amount of nutrients to survive.
Not all plants are like pothos, as long as they have water.
Some plants are even very picky and have very precise requirements for the ratio of various nutrients. Different plants have different nutrient solution formulas. Most of the raw materials in the Haitang Mine can be extracted, but some are still not available.
Therefore, Haitang decided to make a jar of nutrient solution using popular proportions, which is suitable for most plants and is also called a broad nutrient solution. In the nutrient solution formula, the biggest difference is the ratio of nitrogen to potassium.
Haitang took a liter of water and put it into the earthen pot, but it was not full. The earthen pot looked small, but its capacity was very large. By the way, it was heated to about fifty degrees.
Use the raw materials that have been picked from the mine last time, do some simple processing, and then weigh them with a small scale bought from the drug store.
Calcium nitrate, 0.47 grams, potassium nitrate 0.3 grams, pour them into the warm water in the earthen pot. Originally, we also needed a little ammonium dihydrogen phosphate and magnesium sulfate heptahydrate, but now the conditions are not available. Begonia can only use ammonium nitrate, sulfide
Replace it with magnesium. Although it is not well absorbed, it is better than nothing.
After mixing, stir evenly, and these become the mother liquor. Haitang takes out a part of them one by one, pours them separately according to the size of the earthen pot, and then pours water to fill it half full.
