Vermiculite only gardening indoors

Hello gardeners,
when I was a kid, back in the eighties, my school class had an indoor gardening exercise where we grew bucketloads of vegetables indoors - mostly spinach (which is what we called Swiss Chard in Oz).
I remember my teacher calling it hydroponics. We grew it in a box, filled with pellets, which I think was vermiculite. No soil, all indoors, and it produced so much food we had to give it away. 
Does anyone else remember this method, and does it work, or am I imagining things?

    Hmm 🤔 what sort of lighting did the plants have?

    Ma used to grow chard years back ... it was called spinach beet or perpetual spinach back then.

    Yes, it would have been hydroponics and you can grow a wide variety of stuff using it. Used widely by commercial growers. It did have a bit of resurgence in the eighties but then seemed to drop out of the news. Anything inert can be used as the 'growing' medium, and the nutrients are fed in through the irrigation system.
