Plastic helped the development of hydroponics; it'd water proof qualities, durable, reuseable, lightweight and translucent. In the 60s and early 70s, plastic helped fuel the petroleum based technology that drives hydroponics. But with rising oil costs and increasing regulation on chemical pesticides, interest dropped for another 20 years or so until hydroponics again became a viable technology, especially in regard to protecting ground water and soil from pollutants.
