This probably depends a lot on the gardening method. Like, your average gardener with no strategy is probably carbon positive. Ok, but what about biointensive gardening? What about permaculture gardening? What about guerilla gardening? What about aquaponics?

If you're driving to the garden store to get fertilizer, then you're probably carbon positive. If you're composting yourself and building your soil, I don't know.

Edit: looks like it's covered in the video. Will follow up later.

Edit: watched the video. Yes, basically permaculture is way less carbon intensive. The carbon comes from infrastructure (raised beds, sheds, etc).
