We're focused on open source technologies
我们重点关注的是开源技术，
because we believe that that next revolution in agriculture has to be based on open science.
因为我们相信，下一次农业革命一定是建立在开放科学之上的革命。
That was one of the big misses from technology in the last 30 years, was keeping it proprietary, keeping it closed.
过去30年里，农业在科技方面最大的失误之一就是保持科技的私有性和封闭性。
I have an IP strategy, which is to put everything in the public domain.
我的知识产权策略就是把所有技术都纳入公共资源范畴。

the enthusiast, the home body, the hacker, the scientist
或自己的实验室里的创造者、学生、爱好者、
that wants to get involved in their own house or in their own labs.
家庭主体、黑客以及科学家而设计的。
The parts include circuit boards, sensors, lights, and cameras to monitor the plant.

置入特定的表型组或气候中时，
it will express something.
它就会表达一些性状。
That's called a phenotype.
也即所谓的一种“表现型”。
We want to understand under what conditions do those genetics express flavor, nutrition, size, color.
我们想知道这些基因在什么条件下才会表达味道，营养，大小和颜色。
And it has a lot more to do with its environment than its genetic predisposition.
而这点与环境的关系要比与遗传倾向的关系大得多。
So we design CO2, and temperature, and humidity, and light spectrum,
所以我们设计了二氧化碳，温度，湿度，光谱，
and light intensity, and minerality of the water, and oxygen of the water,
光强度，水的矿物质，水的氧气等因素，
then trying to make sense out of what happened.
