Cucumbers

I planted 5 seeds about 2 weeks ago, 1 seed has broken through today. I had them in the greenhouse but after reading on here I've brought them into the house, they are currently on the floor in the living room, but in the morning I put them back on the window sill.

edit. Just checked seed number 2 just broken through, 40% germination so far. My little boy love cuecumbers and can eat 1 per day so hopefully I'll get a good crop this season. My seeds are Carmen F1 from Dobies.
