"Irene, how are the seeds growing in the Petri dish today?"

Jiayi asked Erin as soon as he entered the laboratory.

Erin looked at the green wheat seedlings in the Petri dish in front of her and said, "It's growing very well, it's very green and dense, and there's no sign of getting sick."

In front of Erin were round petri dishes, and the dishes were covered with dense green wheat seedlings. However, the length of one finger was too long, the color looked a little tender. At the bottom of the petri dishes was a layer of brown flocs, fixing the roots of the wheat seedlings.

Because the planting is a bit dense, the wheat seedlings look a little crowded after they grow.

There are more than a dozen Petri dishes here, each of which contains green wheat seedlings, but the wheat seedlings in each Petri dish are not in the same growth. Although they have just sprouted not long ago, the wheat seedlings in some Petri dishes have already tended to wilt.

The solution concentrations in these petri dishes are actually different, and the various ingredients also have seats. This is to compare and find the most suitable solution formula and concentration.

Machi, who followed Jiayi, looked at the green wheat seedlings and said excitedly to Jiayi: "Your soilless cultivation is really useful. These wheat seedlings grow very well."

Jiayi clenched his fist in his heart and shouted "Checrow to death", but said calmly: "This is not a success, it is just a seedling. It will be considered complete success until it is transplanted onto the culture rack and mature wheat. Moreover, the formula of the culture medium at each growth stage also needs to be adjusted. If it is germinated, it is okay to throw it directly into water and soak the seeds."

Li Weier walked out from behind the laboratory bench and said, "Your requirements are too harsh. Take it easy. Everything is done step by step. It is already very good now. You should know that your first nutrient solution died the day after the seedlings emerge."

Jiayi looked at Li Wei'er with black lines. Is this sure it was a comfort? It was not a blow to herself.

Jiayi has been using wheat to experiment with nutrient solution, but his first nutrient solution was too high in concentration. As soon as the seeds germinated, they died the next day because the concentration of the nutrient solution was dehydrated and ate. It was like a pickled cucumber and could not be hardened.

The solution has been updated for several generations. So far, the germination and initial growth of wheat seedlings are no longer a problem, and the most important thing is growth.

Jiayi said to Li Weier: "Now you can accelerate growth. See which of these Petri dishes grows best and how to supplement nutrition during the process."

Although Li Weier is not a druid, as a mage who has refined botany, the spell of rapid growth of plants can still be used. However, her rapid growth spell can only help plants grow quickly, and cannot activate plants to attack enemies like druids.

Therefore, this spell is a bit useless, because the rapid growth of plants consumes very severe ground power. If the ripening is too ruthless, the plants may not obtain enough nutrients in subsequent growth, and may even lead to no grass growing nearby.

However, it is the first time to use rapid growth spells to accelerate the growth of soilless plants, because soilless cultivation is also the first time. However, in theory, rapid growth spells are more adaptable to soilless cultivation, because the nutrients required during the rapid growth of plants can be solved by only adding nutrient solution - it will not lead to poor soil abilities like in the land and affect subsequent growth.

They first transplanted the sprouted wheat surface to the cultivation rack on one side. The cultivation rack is a multi-layer structure wooden rack. On the wooden rack is a layer of sink with nutrient solution. Above the sink is a floating board made of wooden boards, bark fibers, and kapok wool floating on the upper layer of the liquid surface. This is used to fix the plant and keep part of the roots of the plant on the liquid surface to ensure oxygen supply and respiration at the roots.

There are planting holes on the floating plate, and the holes are filled with bark fibers and kapok floes. Jiayi moved the wheat seedlings into the planting holes, so that the lower part of the roots of the wheat seedlings can be immersed in the nutrient solution, and the upper part is retained on the fiber rack. In this way, the wheat seedlings will be transplanted.

After all the wheat seedlings are transplanted, Li Weier comes over and starts to release the spell that urges growth.

Jia quickly stopped her and said, "Let's wait a moment, let them grow for two days first, adapt to the new nutrient solution, and fix the roots."

At this point, he was a little nervous again. In the first two times, they also made the wheat seeds germinate well, but they died during the growth process. Due to the concentration of the nutrient solution, the fault tolerance rate of the plants that urge to grow is not as high as that of planting in the ground.

Two days later, they stood in front of the growth rack again.

Li Wei'er turned to look at Jiayi and asked, "Is it officially beginning now?"

Jia glanced at the growth frame and said, "Let's start."

"Oh, wait a moment!" He just finished speaking, and when Li Wei'er was about to start casting, he quickly interrupted her.

"I'll check the nutrient solution first to see if it's sufficient." After that, he was about to go up to the growth rack to check again.

Li Wei'er was about to cast a spell, but was interrupted by him, and there was almost no magical backlash. Regardless of Jiayi's arrival at the growth rack, she started to release spells while making gestures:

"Have you checked it, why are you checking? Get out of the way. I can't guarantee how this spell will react when released to the human body."

After saying that, she was about to throw the spell over. As soon as Jia Yi saw it, he hurriedly hid aside, and then a ball of green light rubbed against his side and went to the growth rack.

In fact, the magic of urging growth has no effect on the human body. This spell can only urging plants to grow, but not animals to grow. At most, it will only make the subject's hair become more vigorous.

However, Jiayi was not aware of this and said in horror: "You can just let go, what if I become an old man."

However, Li Wei'er didn't have time to answer him, but just glared at him as a revenge that had just interrupted her. She was carefully maintaining the spell to allow the wheat seedlings on the growth rack to grow rapidly.

These wheat seedlings began to grow visible to the naked eye, some of which were like watching a quick video of the plant growth on popular science documentaries, but they became much smoother. The wheat seedlings gradually grew taller, their leaves became wider, and then became like leeks. Then they continued to grow, the stems were raised, the leaves became wider, and more leaves grew.

Jiayi stared at the wheat when the wheat seedlings began to grow. At this time, Jiayi quickly said, "Okay, okay, stop quickly, it's OK."

After hearing this, Li Wei'er quickly stopped the spell. She was also tired at this time and had a thin layer of sweat on her head. In order to maintain this spell, the wheat grew at a constant speed and slowly, it was not easy. It had high requirements for the control of magic and was very exhausting.

Li Wei'er took a breath, walked to the front of the growth rack, looked at Jiayi, who was checking the growth of wheat, and asked, "How is it?"

Jiayi carefully checked the wheat and compared it with the wheat that he had seen in his memory during the growth process. This batch of wheat looked like there was no big problem, but the leaves were a little yellow, especially the old leaves that grew the most yellow, which began to feel yellow and dry, and the tips of the leaves even felt like they were beginning to dry.

"It's okay." Jiayi nodded with satisfaction, "Although it looks a bit malnourished, it's much better than the last time."

The last time they urged them to grow, the wheat seedlings grew too quickly, causing them to turn yellow and dry. Jia didn't even want to save them, and started directly from a new beginning, just like glyphosate was used. It seemed that even if they were saved, they could not be able to head and fill the grout.

The wheat seedlings nowadays also look a bit malnourished, but at least there is room for rescue.

Jia turned his head and saw Li Weier's haggard look, and said a little sorry: "Thank you for your hard work, but next time, I hope I can slow down my growth rate. This time it's still too fast, and I feel that the nutrition is a little unrestrained."

After saying that, he said with some disappointment: "It would be great if the growth rate could be increased at a constant speed. It is still a bit unsatisfactory now."

Erin, who was on the side, heard Jiayi's words and said to Jiayi dissatisfiedly: "Do you know how difficult this is? You are not satisfied, so the requirements are too high."

This time, even Maggie and Chester did not help Jia Yi talk. This requirement is indeed too high. It is like lifting a barbell. The muscle bull can lift the barbell, but if you want to lift it at a constant speed and put it down at a constant speed, especially limiting the speed, making it slower the better, it is simply a difficult thing.
