Soil & Soilless

What do you mean by soilless mix: what is it? A soilless mix is a mixture of components in which it is possible to grow a plant but which does not contain soil in the traditional sense, that is, no garden soil or compost.
無土混合物是什麼﹖
無土混合物是可以用來種植植物的幾種物質的混合但裡面不含傳統的土壤##CONTINUE##

Here is a simple example of a Soilless mix: 50% Perlite 50% Vermiculite
這裡有一個簡單的無土混合的範例：50%的珍珠岩和50%的蛭石

Here's another: 40% Castings (Worm i presume although the author does not specify) 30% Vermiculite 30% Perlite
另一個範例是40%的Castings和30%的蛭石和30%的珍珠岩

Here however is a warning on Soilless mixes which it is important to note.
關於無土混合物有一個需要注意的地方

IF you happen to miss a couple of waterings the plant can dry out quick because the mix will not hold much moisture. Soil is much easier and will provide nutrients throughout the grow, lessening the need for ferts. contributed by glass joe >> Soilless mediums can contain peat moss (like pro-mix)as an ingredient along with worm castings, perlite, etc
如果你不小心忘記澆幾次水
你的作物可能會很快乾枯
因為無土混合物的保水性比較沒那麼好

靚土或其它培養土都是屬於無土混合物
而且都有事先加肥料在裡面了
所以開始種植的第1~2個星期可以不用施肥
