We create three things: gas, liquid soil amendment, and solid soil amendment of peat moss like material.

气体，类似泥炭沼泽的液体土壤改良和固体土壤改良。

The peat moss that is used in many potting mixes, however, can take thousands of years to grow.

然而，许多盆栽混合物中使用的泥炭藓可能需要数千年才能生长。

Something like peat moss, but not soil, would be placed in the box on top of the screen, which would hold it above the water in the bottom of the box.

盒子内屏幕上方可以放上泥煤苔这样的东西，而不是土壤，放在盒子底层水面之上。

Now most of these farms are hydroponic or aeroponic systems, which means that instead of using soil, they use a substitute material like polyurethane sponges, biodegradable peat moss and even use inorganic materials like perlite and clay pellets.

现在这些农场大多是水培或气培系统，这意味着他们不使用土壤，而是使用聚氨酯海绵、可生物降解的泥炭藓等替代材料，甚至使用珍珠岩和粘土颗粒等无机材料。
