African Bag Seed Experiment 1

So, I'm not really sure what strain these seeds are, they're 'bag' seeds from an unexpected stash. What I do know is that it's South African weed and therefor almost certainly Sativa,most likely Swazi Gold, given where the weed was bought, on the borders of the Kruger National Park. So far all the seedlings seem quite robust, dealing with London April temperatures. They're all the same size.
