Tweetable Quotes

“Actually, that’s the whole idea with vertical farming. It makes a lot of sense to do it when you can locate your farms very close to your customers and distribution centers for major customers.” (13:36) (Dr. Christian) 

“I was always very interested in healthy food, not only the value of it, but how to improve our daily nutritional intake - starting with my own family - and then realizing there was a real need for that. And, in talking to head chefs from all of these high-end hotels, we realized there was so much desire to improve the quality of their offerings.” (19:06) (Dr. Christian) 

“I think that no matter how much technology you use, if you don’t have talented growers, the quality suffers.” (22:34) (Dr. Christian) 

“Leadership is a people business. So, yes it was also a personal journey for me going from being focused on technology, technology management, and technology development to working with people. I learned a lot from them and hopefully they learned from me as well. But yeah it’s a transition. I would say being very crisp and focused on your message so you don’t put out confusion is super important.” (23:54) (Dr. Christian) 

“Singapore is becoming known as the ‘Food Valley,’ sort of like Silicon Valley, given their challenges of being a net importer for ninety percent of their food needs.” (35:56) (Dr. Christian) 

“Something I’ve changed my mind about is that at one point I thought that maybe vertical farming could solve all the issues in the world, but no. We have to understand that we have a place in the food system. And I don’t want to say we need to be humble, but we cannot chase projects that are too unrealistic because many of these projects end up using more resources and creating more problems than we want to solve. But continuing to innovate and expand our footprint in the food industry, but doing it in a way that makes sense and doesn’t use more resources than other existing approaches or more traditional approaches.” (42:13) (Dr. Christian) 

“We know that our product is good. We know that we’re growing the product in a way that, in many aspects, is more sustainable. We are addressing some real issues in the food chain. We really need to focus on the economics.” (44:16) (Dr. Christian)
