Vertical Growing

Vertical farming has become a hot topic in the last couple years in the Green Industry & is only continuing to grow in interest & popularity.

A big push has been made for Vertical Farming due to a few factors:

  • Decreasing amount of arable land
  • Increasing amount of extreme weather
  • Uses less land to grow more food
  • Uses less water
  • Uses less fertilizer
  • Moves Green Industry closer to technology

Here are a few of the ways you can grow vertically – indoors & outdoors!

Grow Racks

Grow racks are probably the most popular method that is currently out there. Some companies are growing 10-15 levels high, or even higher in some cases! Crops grown in these systems is limited to leafy greens & herbs due to the smaller space they occupy. Commercial crops like Tomatoes & Cucumbers are already “vertical growing” – some grow up to 30 feet tall!

Zip Towers

Commercialized by Bright Agrotech, these grow towers are essentially like 2 gutters sandwiched together with a foam growing media that you grow the plants in. Unlike a gutter that lays horizontally, these are grown vertically and then you stack towers side-by-side. I have not tested these out, but have had my eye on them since the first time I heard about them! You can grow them outdoors, but I feel like it would be more ideal to do indoors or in a greenhouse to maximize production.

Grow Towers

There is a wide variety of Grow Towers out there. Some are hydroponic or aeroponic – meaning that the roots are either growing in nutrient-rich water, or the roots hang in the air & is misted with nutrients & water. Typically, those types of towers are also using artificial lighting, but I have seen some growing in greenhouses.

Other Grow Towers do use soil – some are made by growers themselves, but I am going to be testing this Tower out this summer that holds 250 plants & uses soil – so excited to see how well it works! This is going to save me from building as many Gutter Growing systems & will save a ton of space as well! Instead of 250 heads of lettuce taking up 250 square feet, it will take up 4 square feet – pretty impressive right?!

Gutter Growing Systems

This has been made popular by In.Genius Farms out of Canada & I’m excited to give this a whirl this season. I think I’ll mainly grow leafy veggies, herbs, green onions, & maybe even strawberries. My concerns are that they will not stay hydrated enough – & will be hard to keep watered when temperatures get in the 90s this summer. Not only the water issue, but the actual heat issue – how will that affect the plants roots, will it bake them? I guess there’s only one way to find out!

I think that Vertical Farming will only continue to expand, but there are some challenges that need to be tackled:

  • Energy usage from Grow Lights
  • Ease of harvest from higher racks – typically a scissor-lift is used
  • Crops grown – most vertical growers only grow leafy greens, microgreens & herbs
  • High startup costs

Vertical growing has been in theory for nearly 100 years, but companies are just beginning to tackle this growing option with plant factories & new growing systems coming out all the time. There are challenges, but through testing, failing, & innovating, I believe that this will be the future of growing as the population expands & the size of farms continues to shrink.

  1. This is such an inspiring post. I am really interested in how the gutter garden works out. Looking forward to a future post. For indoor grow lights next year, I’m gonna give LEDs a try.

    1. Thanks for reading! The gutter garden didn’t happen yet but I have been using this garden tower with mixed results. So tough to keep the proper water levels and to battle the summer heat in Ohio. I think it’ll do better from here on because the weather has been more mild – but tough to grow when it’s 90-100+ degrees! I’ll do a post on it soon! And good luck with the LEDs – they work wonders if you have a quality light
