I watched some of those videos.
I was actually very pleased to see the dandelion one, because people always talk about picking them and eating them, but to me they don't really look like edible plants.
She showed us how she picked them AND how she cleaned them. It is a very time consuming practice which is why people probably stopped eating them when they didn't have to anymore.
This is my first year that I might get fruits from a garden. I grew tomatoes in a container once or twice before but since moving back to San Diego I have not had a succesful harvest.
This year we already ate mandarins and apples from trees, rainbow chard, bits of arugula and collard greens, a giant onion, a chili, and the tomatoes look like there will be hundreds.
Let's hope. I'm following, looking forward to seeing more about your green house and plants.
