Two industrial-grade variable frequency water pumps with a flow rate of 20,000 L/H are required as the main drive core.
This thing operates like a small water pump.
For visual purity, no plastic pipe can be seen; all pipes must be hidden.
The pipeline pre-burial scheme involves pre-burying a 50mm diameter dark PVC rigid pipe in a 15cm thick layer of volcanic rock.
The water outlet needs to pass through three filter tanks.
The first step involves coarse-pore bio-cotton to intercept residues and large particles.
The second step involves high-density white cotton filters that adsorb suspended particles.
The third layer, a matrix of microporous ceramic rings and quartz spheres, provides a vast surface area for nitrifying bacteria.
The pen tip moved quickly across the paper, leaving clear writing.
This only solves the problem of the water appearing clear.
The core challenge in creating landscapes along polar rivers lies in temperature control.
The wild waterways of Kodiak Island are icy cold year-round.
To maintain this cool feeling in the temperature-controlled room and prevent the aquatic plants from rotting.
Once the indoor heating is turned on, the water temperature will quickly exceed ten degrees Celsius, which will then lead to an ecological disaster.
Therefore, chiller units are essential core equipment that must be included.
Su Wei tapped his fingers on the keyboard, switched pages, and typed in "industrial-grade titanium tube chiller".
Titanium alloy pipe walls are the only material that can resist corrosion from the weak acidity in water.
The page switches again, returning to "Plant Ecology and Soil Engineering in Closed Environments".
Entering the most challenging woodland ecological zone, the vertical greening of walls is a crucial step.
Physical construction and water retention strategies of moss walls.
Under the influence of gravity, moisture will accumulate at the bottom of the wall, making the plants at the top extremely susceptible to dehydration and death.
The conventional approach is to lay down absorbent cloth and cover it with absorbent resin mud.
Upon seeing this, Su Wei paused for a moment.
Water-absorbing resin mud is a type of high molecular weight chemical polymer.
The obvious drawback is the pungent smell of industrial glue.
Moreover, it has a disgusting texture similar to a cheap sponge.
This is not what Su Wei wanted.
We must completely abandon industrial chemical additives and find purely natural adhesives and water-retaining matrices.
Slide your finger across the touchpad to quickly browse the third document, "Analysis of Cold-Region Mosses and Indoor Cultivation Data Records".
Their eyes scanned the massive amount of data with the frantic speed of a scanner.
Found it.
Natural matrix formulation method.
It uses deeply humified peat moss, mixed with highly aerated akadama soil and tree fern fiber.
To improve adhesion to vertical walls, 3% to 5% natural bentonite powder can be added.
The pen fell again, recording this set of core formula parameters.
Peat soil 60%, red jade soil 30%, snake sawdust 10%, bentonite 5%.
Finally, add purified water and stir vigorously until it becomes a thick paste.
This solution solves the problem of natural adhesion without leaving a trace.
Next is the simulation of the light frequency band.
Polar plants in the understory of virgin forests dislike direct sunlight and are only adapted to soft, diffused light.
Ordinary lighting must be abandoned in favor of full-spectrum LED cold light sources.
The color temperature parameter is locked in a cool range of 6500K to 8000K.
The hanging height of light fixtures must not be less than 60 centimeters.
Below this distance, high-intensity photons will directly burn through the fragile thallus of the moss.
The data in the hard copy increased, the handwriting became faster and faster, and page after page was turned.
Three hours passed quietly.
The wall clock ticked monotonously.
Su Wei's back muscles were somewhat stiff.
The intense intake of theoretical data caused his temples to throb.
My eyes also became dry and sore from staring at the screen for so long.
But he had no intention of stopping, because his efforts were paying off.
At the edge of the field of view, the dashed progress bar below the Crafting Module icon has become extremely solid.
The eerie blue light steadily climbed within the progress bar.
95%.
96%.
98%.
This visual feedback confirmed that Su Wei's current learning path was correct.
The system, this machine, is capturing, dismantling, and reassembling these ecological parameters deep within his consciousness.
It will soon generate a brand new skill for the Su Wei Union.
Just as Su Wei was looking forward to it, the progress bar hit a wall and got stuck at 99%.
The blue light stopped spreading.
Su Wei's fingers hovered in mid-air as he typed on the keyboard, his brow furrowed.
All hardware and physical parameters have reached their theoretical limits.
He checked temperature, humidity, light, filtration, and natural substrate repeatedly, leaving nothing out.
Why is it stuck?
This 1% delay means that a crucial closed loop is missing from the ecosystem's logical chain.
Su Wei closed his eyes and took a deep breath. He pinched the bridge of his nose with his index finger and thumb and pressed hard.
He quickly replayed all the data he had just recorded in his mind.
What exactly was missed?
A perfectly proportioned mix of stones, soil, filter media, and temperature-controlled cold water, plus expensive lighting—can this really be called ecological?
No, Su Wei denied it in his heart.
This is at best a sterile morgue that is forcibly kept alive by equipment.
The real Kodiak Island wilderness, every inch of its soil is filled with plunder, death, and energy transformation.
Animal excrement, fallen leaves, and the corpses of dead insects.
These organic materials fall onto the surface of the peat soil every day.
If left untreated, these substances will quickly ferment and rot inside the exhibition hall.
Organic acids secreted by plant roots will continue to accumulate, causing the soil pH to drop sharply and disrupting the acid-base balance.
An excessively acidic environment can cause heavy metal ions to be released, eventually poisoning all the moss on the wall within a month.
Su Wei suddenly understood.
The reason why expensive commercial aquariums on the market need to be completely overhauled is because they lack the ability to handle waste.
They appear vibrant and full of life, but in reality, they are merely delaying their death.
What Su Wei wanted to create was a microscopic world that could self-metabolize and endlessly regenerate.
Decomposer!
A vital energy transfer network hidden underground.
At that moment, my thoughts suddenly became clear.
Su Wei suddenly opened his eyes, the dryness in them vanishing, replaced by a fervent desire to discover the truth.
His fingers returned to the keyboard, the movement so fast it left afterimages.
Close the previous page and open the top-level search bar of the academic database.
He compressed all the theoretical parameters in his mind, bringing them together into the final, and most fatal, question.
With a firm tap of the key, a line of characters quickly appears in the search box.
