Publisher Description

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.

Barely worth the pixels it took to make this.

It had a few links by the mercy of glocks it didn’t save it. Barely worth the pixels it took to make this. As useful as a fire extinguisher after the fire burns all your items.
