GrowUp Box Tours
Time Out says
Friendly warning! We're working hard to be accurate. But these are unusual times, so please check that events are still happening.
It won't solve climate change single-handedly, but we'll damned if The GrowUp Box isn't a nifty piece of sustainability worth checking out. Using a technology called 'aquaponics', the box creates a (nearly) self-sustaining loop, where nutrient-rich waste water from fish tanks is pumped into the roots of plants. Next, the plants purify the water, which is then pumped back into the tanks. And so on. The results speak for themselves: using only fish food and the power required to operate the pumps, the GrowUp Box is capable of producing around 250kg of fish and 400kg of salad each year. Now you can et up close and personal with the aquaponics activity on one of their Box tours. Book here.
