So I want to grow hydroponicgourmet organic lettuces .

我想种溶液培植的有机生菜。

In the hot weather the lettuces suddenly ran to seed .

炎热的天气下，莴苣突然开始花谢结子。

No , they haven 't any lettuces , but they have some bananas .

他们没有油麦菜,但是他们有一些香蕉.

Are these lettuces home grown or did you buy them in the market ?

这些生菜是自家种的呢,还是你在市场上买的?

Harvest leaf lettuces when the leaves are big enough to eat .

当叶子长到能食用的时候，就可以采摘叶生菜了。
