وصف الناشر
Experimental hydroponics have appeared from the 17th century when biologists discovered that plants can grow without soil. From that moment on, numerous experimental hydroponics projects have been initiated in an effort to improve the method. Even if it experimental hydroponics have a long history, the real progress in the field appeared after 1970 when plastics began to be used reducing technological expenses and stimulating farmers to think about the system's viability.

It will give theory and nothing else. there is nothing about how to set up a system in this book.
Barely worth the pixels it took to make this.
