The next day, Gwen took Orlando to the laboratory and visited Jiayi and their soilless cultivation experiment.

Then, Gwen told Orlando: "They just want to build a magic array here to accelerate plant growth. And according to Jiayi's requirements, the speed cannot be too fast and the speed must be kept even, so as to avoid problems that grow too fast and too fast, so there is no time to deal with it."

Just now, she had already introduced Jiayi's soilless cultivation theory to Orlando. Although Orlando was not familiar with it, the results in front of her could still be seen.

Orlando called Jiayi over and asked, "How fast should you not be too fast? Is there a metric?"

Jia Yi thought for a while and said, "If possible, it is best to adjust the speed. If you want it to be fast, it is fast, and if you want it to be slow, it is best to shorten the wheat growth cycle to within one month. In this way, we have enough time to do multiple experiments and get more data."

If it weren't for greenhouses and soilless cultivation, it would take a year to not cultivate a season of wheat. If this continues, even if Jiayi graduates, he will not be able to cultivate a few seasons of plants. If you want to do this well, it will probably take ten years to remember it.

With Jiayi's popularity among the past three minutes, how could it take so long to spend on this? Even if Jiayi is willing, readers will be annoyed.

When he first wanted to plant elven rice, he didn't think so far. He just thought about cultivating seedlings first, but he didn't expect that the growth acceleration array would be. If he just cultivated the seedlings and planted them well, it would always take half a year to plant them.

Orlando paused for a moment, calculated it briefly in his mind, and said: "It is difficult to adjust the speed independently. Even if it is successful, the room for adjustment will not be too large. However, the speed you want is the growth cycle of spring wheat for 3 months and winter wheat for 8 months. You have a greenhouse and good temperature management, so it should be considered spring wheat. If you want to compress it within one month, there may be problems. In fact, it may be shorter."

Jiayi looked at Orlando in surprise. He didn't expect that he knew so much about the growth cycle of wheat. Jiayi saw winter wheat in this world. Although he knew that spring wheat was like this, he didn't know what the growth cycle was.

In this way, the mages were not as self-centered as they imagined and did not care about agriculture. Jia Yi thought so in his heart.

Gwen said on the side: "It is best to add a free switch array, because photosynthesis cannot be performed at night. If you use the growth array at night, there may be problems."

When Gwen reminded him, Jia Yi was suddenly shocked. If she hadn't reminded her, they would have had to have the first crop of wheat died at night before they could react. At night, plants all perform respiration and cannot perform photosynthesis. If the growth acceleration array has been used, it would be equivalent to not having any sunlight for dozens of days, and the plants would starve to death.

The wheat is about to turn yellow.

Jia quickly recorded this point. He could not use the growth array at night, so he had to close it.

After the on-site survey, Orlando and Gwen went back to design the magic circle needed by Jiayi, while Jiayi began to design a new nutrient solution.

The original nutrient solution used in the leaching solution of stone powder. Although the stone powder contains a large amount of trace elements and is also very rich in various nutrient elements, it is not conducive to the preparation of nutrient solution because the content cannot be accurate and it is very difficult to dissolve, which is not conducive to the preparation of nutrient solution.

Jiayi decided to use acid to dissolve these stone powders and purify them, and then use the purified solution to prepare the nutrient solution, so that the concentration of the nutrient solution can be controlled more accurately.

Now the theoretical basis of soilless cultivation has been completed, and some details can be optimized.

Jiayi first prepared sulfuric acid in the laboratory. When he invented the explosives, he not only equipped with black gunpowder, but later made nitric acid, making thyroid nitric acid-glycerides, and then absorbed it with magic dust to create alchemy explosives. In order to create nitric acid, he also made sulfuric acid.

After the sulfuric acid was made, he dissolved the stone powder with sulfuric acid. In order to enhance the dissolution performance, he also added some magical strong acids to increase the dissolution performance.

After purification and crystallization, Jiayi also processed saltpeter and obtained various purer potassium nitrate, ammonium sulfate, as well as trace element fertilizers such as phosphorus fertilizer, calcium fertilizer and magnesium.

These newly purified fertilizers have good solubility, are conducive to plant absorption, and are more convenient to install nutrient solution, and are easy to control the concentration and the content of various ingredients.

After three days, Orlando's plant growth array was designed.

Orlando and the others came to the laboratory and smelled a strange smell as soon as they entered the door. Orlando frowned and looked at Jiayi and said, "What does this smell? You might be peeing in the laboratory, right? This laboratory is just for you, so you can't do it randomly."

Jia Yi covered his forehead one by one and lamented: "What? It's not urinating. This is the smell of ammonia. I have been mixing new nutrient solution these days, and a lot of ammonia is produced in the process, so this smell is."

Orlando still knew about ammonia, but he didn't think about it for a while. After all, there was no fertilizer in this world, and there were few ammonia products in the experiment, so he didn't think about it for a while.

"Make up the nutrient solution? Last time I came here, you put several large tanks here, all of which tasted so heavy."

Gwen said as he released a spell of fresh air for himself, blocking the smell from the lab outside.

In the laboratory, in addition to the smell of ammonia water, there is also the sour smell emitted during the process of mixing strong acids, as well as the pungent smell of lime water. Various flavors are mixed together, which is simply sour and refreshing.

But after staying here for a long time, if you get used to it, you won’t feel it. As the saying goes, it’s like entering a bay with abalone, and if you don’t ask about its smell for a long time, it’s probably this kind of feeling.

Jia quickly opened the window and controlled the airflow to blow the smell of the room away from the window. After several minutes, the smell in the laboratory faded, and Professor Gwen removed the spell that blocked the smell on his head.

Orlando and Gwen came to the front of the window and began to arrange magic circles. While laying them out, Orlando taught Jiayi a lesson: "Next time, you must pay attention to this kind of experiment with strong irritating odor. These are harmful to the body. Although the mage often receives erosion from magic elements and has strong resistance, if you come into contact with these harmful things for a long time, it is not impossible to get sick or even die."

Although the mage's body is not strong and its physical strength and physique is far inferior to that of a knight, at least its physical fitness is stronger than that of an ordinary person, and its resistance is even more unmatched by an ordinary person, and the knights can't do it either.

Gwen added: "Some of the older curses use these harmful gases to erode the human body. You can think that your current experiment has produced a weak curse. If an ordinary person is next to you, you will be hurt."

It seems that many rumors about mages conducting vicious experiments are probably because mages are not standardized when conducting experiments, and randomly emit waste from the experiments, which eventually pollutes the surrounding environment.

The so-called curse of the mage is a pot that does not properly handle waste materials in the experiment. Thanks to the mage who has not used radioactive items to conduct the experiment, otherwise this curse would have been circulating for many years.

Li Weier and the others watched Orlando's carving the magic circle next to him. Jia nodded and said, "I know, teacher, I will pay attention next time. This time, because I'm in a hurry, I overlooked this point. Next time I go to an open place for experiments."

Jiayi also relies on his health, so he lacks the necessary foresight for the side effects in the experiment. When he was doing the experiment in junior high school, he just cleaned the hydrochloric acid when he touched his hands, and he still felt smooth and greasy.

For safety reasons, the experiments conducted by junior high and high schools for students rarely have more dangerous concentrated nitric acid or concentrated sulfuric acid. Most of them are diluted, and it will be fine if you rinse the water.
