"Erin, how are the seeds growing in the petri dish today?"

As soon as Kaichi entered the lab, he asked Erin.

Erin looked at the green wheat seedlings in the petri dish in front of her and said, "The growth is good, the green is very dense, and there are no signs of illness." ”

In front of Erin's eyes were round petri dishes, in the petri dishes was a layer of green dense wheat seedlings, but more than a finger long, the color looked a little tender, and the bottom of the petri dish was a layer of brown flocculent object, which fixed the roots of the wheat seedlings.

Because the planting is a bit dense, after the wheat seedlings grow, it looks a little crowded.

There are more than a dozen petri dishes here, and each petri dish has green wheat seedlings in it, but the wheat seedlings in each petri dish are not growing consistently, although they have just germinated not long ago, but the wheat seedlings in some petri dishes have a wilting trend.

The concentration of the solution in these petri dishes is actually different, and the various components also have different seats, which is to compare and find the most suitable solution recipe and concentration.

March, who followed Jiayi, looked at these green wheat seedlings and said excitedly to Jiayi: "Your soilless cultivation is really useful, and these wheat seedlings are growing very well." ”

Jia Yi clenched his fists in his heart and shouted "choking to death", but said flatly: "This is not a success, it's just a seedling, it is not a complete success until it is transplanted to the culture rack and the wheat is mature and fruitful, and the formula of the culture medium at each growth stage also needs to be adjusted, but if it sprouts, it is okay to throw it directly into the water and soak the seeds." ”

Li Weier walked out from behind the laboratory table and said, "Your requirements are too harsh, take it easy, everything is done step by step, and now it is very good." You know, your first nutrient solution will die the day after it emerges. ”

Jia Yi looked at Li Weier with black lines, is this sure to be a comfort?

Kaichi has been using wheat for nutrient solution experiments, but the concentration of his first nutrient solution is too high, and the seeds have just germinated, and the next day they die due to dehydration due to the concentration of the nutrient solution, just like pickled cucumbers, which can't be hardened.

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

Jia Yi said to Li Weier: "Now you can accelerate the growth, see which of these petri dishes grows the best, and how to supplement the nutrients in the process." ”

Although Li Weier is not a druid, as a mage who has refined botany, she can still use the spell of rapid growth of plants. However, her fast-growing spell can really only help plants grow quickly, not like the druids, urging plants and animals to attack enemies.

Therefore, this spell is a bit of a chicken rib, because the rapid growth of plants is very serious for the consumption of soil power, if the ripening is too ruthless, the plant is likely to not get enough nutrients in the subsequent growth, and may even lead to the lack of grass nearby.

However, this is the first time that a fast-growing spell has been used to speed up the growth of plants cultivated without soil, as it is also the first time that soilless cultivation has appeared. However, theoretically, the rapid growth spell is more adaptable to soilless cultivation, because the nutrients needed in the rapid growth process of plants can be solved by adding nutrient solution - it will not be like in the land, resulting in poor soil fertility and affecting subsequent growth.

They first transplanted the sprouted wheat noodles to the side of the culture rack, the culture frame is a multi-layer structure of the wooden frame, above the wooden frame is a layer of water tank, the water tank is a nutrient solution, and above the tank, is a layer of wood board, bark fiber, kapok wool mixed into a floating board floating on the liquid surface, which is used to fix the plant, and keep part of the roots of the plant above the liquid surface, to ensure the oxygen supply of the roots.

There are planting holes on the floating board, the holes are filled with bark fiber and kapok batting, Jiayi moves the wheat seedlings to the planting holes, so that the lower part of the roots of the wheat seedlings is immersed in the nutrient solution, and the upper part is retained on the fiber shelf, so that the wheat seedlings are transplanted.

After all the wheat seedlings were transplanted, Li Weier walked over and began to release the spell of growth.

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

At this point, he was a little apprehensive, the first two times, they also made the wheat seeds germinate well, but they died in the process of growth, because of the concentration of the nutrient solution, the error tolerance rate of the growth plants is not as high as that planted in the ground.

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

Li Weier turned her head to look at Jia Yi and asked, "Is this officially the beginning?"

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

"Well, wait a minute!" he had just finished speaking, and when Li Wei'er was about to start casting the spell, he quickly interrupted her again.

"I'll check the nutrient solution first to see if it's sufficient. With that, he was going to go up to the edge of the growth shelf again to inspect it.

Li Wei'er was just about to cast a spell, but was interrupted by him like this, so there was no magic to fight back, and regardless of Jia Yi when she arrived next to the growth frame, she began to release the spell while gesturing, and said:

"Haven't you already checked it, what else to check, get out of the way, I can't guarantee how this spell will react when it is released into the human body. ”

After saying that, she was about to throw the spell over, and when Jia Yi saw it, he quickly dodged to the side, and then, a cloud of green light grazed his side and reached the growth frame.

In fact, the growth magic has no effect on the human body, this spell can only promote the growth of plants, not animals, at most, that is, to make the recipient's hair more vigorous.

However, Jia Yi didn't know this, and said with some horror: "You said let it go, what if I become an old man." ”

However, Li Weier didn't have the time to answer him, just glared at him, as revenge for interrupting her just now. She was carefully maintaining the spell to make the sprouts on the growth rack grow quickly.

The seedlings began to grow visibly with the naked eye, some like watching a quick video of plant growth on a popular science documentary, only much smoother. The seedlings grow taller, the leaves become wider, then they become leeks, and then they continue to grow, the stalks are taller, the leaves become wider, and more leaves grow.

Jia Yi stared at the wheat when the wheat seedlings began to grow, and at this time, Jia Yi hurriedly said, "Okay, okay, stop quickly, it's already okay." ”

Li Weier listened, and hurriedly stopped the spell, she herself was tired at this time, and a thin layer of fine sweat appeared on her head. It is not easy to maintain the constant and slow growth of wheat with this spell, and it requires a lot of control over the magic, and it is very draining.

Li Wei'er breathed a sigh of relief, 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 inspected the wheat, and compared it with the wheat he had seen in the growth process in his memory, this batch of wheat did not seem to have any major problems, but the leaves were a little yellowish, especially the oldest old leaves, which began to have a feeling of yellowing and drying, and the tips of the leaves had a feeling of starting to dry up.

"It's fine. Kaichi nodded with satisfaction, "Although it looks a little malnourished, it's much better than the last time." ”

The last time they urged to grow, the wheat seedlings grew too fast, resulting in direct yellowing and drying, Jia Yi didn't even have the heart to save, and started anew, just like that glyphosate, it seems that even if it is saved, it can't be tasseled and filled.

The wheat seedlings also look a little malnourished, but at least there is room for salvation.

Jia Yi turned his head and saw Li Wei'er's haggard appearance, and said a little apologetically: "Thank you for your hard work, but next time, I hope to slow down the growth rate a little more, this time it is still too fast, and I feel that the nutrition is a little unable to keep up." ”

After speaking, he said with some disappointment: "It would be nice to be able to increase the growth rate at a uniform rate, but now this is still a little unideal." ”

Erin on the side heard Jiayi's words, and said to Jiayi dissatisfied: "Do you know how difficult it is to do this? ”

This time, even March and Chester didn't help Jia Yi speak, this requirement is indeed too high, just like lifting a barbell, muscle tyrant can lift the barbell, but if you want him to lift it at a uniform speed, put it down at a uniform speed, especially if you limit the speed, let him slower the better, this is simply embarrassing.

Jiayi also knew that his request was a bit excessive, and said apologetically: "I know that this is really difficult, but I just think about it, and I don't necessarily mean to ask for it." ”
