Houseplants in Space:GotG3

Join Emma the Space Gardener as she explores gardening on Earth... and beyond! There's some great news for space gardeners this week, involving space to grow in, bricks to build with and... hibernating squirrels. And you can discover how many plants it would take to provide your own personal oxygen supply, and what would make a good houseplant in space. Oh, and there's still time to enter the chilli seed giveaway!
