Windowfarms is an easy to assemble and use vertical hydroponics system. No grow lights are needed. Just put them by a sunny window and harvest food year round.
A Windowfarm is a vertical, indoor garden that allows for year-round growing in almost any window.
In the hydroponic system, nutrient-spiked water is pumped up from a reservoir at the base of the system and trickles down from bottle to bottle, bathing the roots along the way. Water and nutrients that are not absorbed collect in the reservoir and will be pumped through again at the next interval.
