I worked for the company that developed the technology. Personally not much of a green-thumb myself, but it's great to see how much you can grow with vertical towers, either in a greenhouse or indoors with LED lights. You can grow about 3-4x what you would get with a flat grow bed for many plants [1]. While the towers are great, the real trick is the grow media as you want it robust enough to survive while not suffocating the roots.

For those interested in starting your own farm or just gardening I'd highly recommend "UpStart Farmers" [2]. A friend of mine help's moderate it and is really focused on helping people learn vertical farming and aquaponics. They have an enormous selection of content regarding various aspects such as nutrient mixes, dealing with pests, etc. The community is also active and helpful to each other.

FYI: This is from the Canadian licensee's of the original Bright Agrotech that was acquired by Plenty Ag [3]. I'm bullish that indoor farming will be a big boon in providing more localized and therefore fresh and nutritional vegetables and leafy greens for much of the world's population. The economics are slowly improving with LED efficiency increases and capital infusion to scale farms.
