Popular in the 70s, self-sufficiency has seen a new resurgence, with many people turning their hands to growing their own fruit and vegetables. Even those without gardens or outside space can get in on the act with indoor plant growing systems.
These systems generally operate hydroponically (with nutrients added to water rather than with soil) and with grow lights. This means food – or flowers and house plants – can be grown indoors unaffected by the weather or seasons–and without pesticides.
