Vertical Farming FAQs

Getting started with urban farming can feel overwhelming. That’s why Greenhouse Tower Farms offers complimentary consultations to help you navigate the process of starting your Vertical Farm. Our experienced team can answer your questions, discuss your goals, and provide valuable insights.

Aeroponic farming is the process of growing plants in an air or mist environment, without the use of soil. This innovative approach provides plants with the ideal amount of nutrition and hydration. And it’s sustainable, too — using a fraction of the water and land required by traditional soil-based growing methods.

An 11-section tower — which can grow up to 44 plants simultaneously — is 97 in. tall and weighs about 220 lb. when full. The 20-gal. reservoir at the tower’s base measures 30 x 30 in.

Note: Greenhouse Tower Farms units are modular. So you can grow more or fewer plants per tower if you prefer.

The short answer is about 278 watts per tower per day. We arrive at that answer with some simple math.

Tower Gardens pumps are rated at 58 watts per hour. And running the pump on the recommended cycle of 3 minutes on / 12 minutes off adds up to 4.8 hours per day. So, 58 watts x 4.8 hours = 278.4 watts per day.

Just multiply that figure by your local energy rates to determine approximate electricity costs per tower.

Experts in human and plant nutrition developed the Greenhouse Tower Farms nutrient solution to ensure it safely nourishes plants and those who ultimately eat them.

The best part? It’s the only plant food you’ll need — for all plants in any growth stage. Pretty simple!
