Christine Tan: Okay Ben, so you were working for Marina Bay Sands, Citibank, and UOB, what made you leave corporate life and do something crazy like vertical farming?

Benjamin Swan: It all started with an article on Facebook. I was on my way home from work and I read an article by Dickson Despommier on the future of farming and vertical farming very specifically. I was looking at a lot of the illustrations and thought to myself, you know, this space that is being used in these illustrations just wouldn't work for Asia given our land scarcity, especially here in Singapore and even in Hong Kong. So I went home that night and jumped on archiCAD and actually rendered up pretty much what you see up the back of the facility today. I was inspired by that and then started learning about indoor farming. I went on to Professor You and Dr. Google, which is YouTube and Google, and actually learnt what is traditional farming and applied a hypothesis on how growing could happen inside of a building using those renderings. I came up with an excel sheet and came up with a hypothesis and took it for a very long test drive. I used that excel sheet to effectively solve problems of indoor farming.

Christine Tan: Why this passion on farming? Did you think you could really make a difference?

Benjamin Swan: I felt that everything I have done in my life kind of boiled down to this point. My construction days, working as a banker, all my skills that I had learnt, I felt that this was my opportunity to do something that would make a difference, an opportunity to fight the good fight. And why farming? Farming right now we know is a problem. We are reliant on techniques that have been used for centuries and whilst we are trying to bring in automation, and improving the ways we're using machinery and so forth, the thing that we can't improve is land usage. So vertical farming can solve that problem. Growing our kale indoors, we're 127 times more efficient than traditional farms per square foot.

Christine Tan: You have no background in agriculture. Did you not think of the risk you were taking when you started the business?

Benjamin Swan: Absolutely, it was a calculated risk. So I did all of this whilst working full time. So I'd finish calls from New York when I was working for Citibank in the early hours of the morning, and I'd go underneath my business partner's pool to go and take measurements of plants so I could understand, you know, all the inputs and outputs of the plant, the diminishing returns on those imports so I could optimize growing. And to be completely frank for the first six months of exploring this space, it just didn't work. The numbers weren't making sense especially on the capex. I mean this is a very capex heavy industry. It wasn't until about six or seven months after starting to trial different lights, different techniques. When the cost for LEDs started to come down, then it started to make sense. So obviously I started pushing a bit harder.
