A lady's first autoflowering grow

First time grow and I'm very excited! Decided to grow 3 autoflowers at once, all in the same conditions with no extra lighting or real push for a big yield. I'm just happy to see where these babies go with natural light, and as I don't have a garden I'll be utilising the top of my boiler cupboard (under a slanted skylight) and a small balcony area just outside a normal window. Once they're a bit bigger I'll move them all to a large bright windowsill. So this is the first week of growing 3x royal dwarf seeds, using the starter kit from royal queen seeds to germinate. Once popped I transferred these to some fairly wide 8 litre pots half filled with some multi purpose compost with nutrients. I couldn't find any perlite but figured I could top the soil up with a mix once they've grown a bit more. Finding it hard to decipher each one, so my partner suggested naming them... So now we have Brienne, Sansa and Arya! Based on their heights at the moment, but lets see how they grow :-)
