Spanish grow

hi im also a first time grower.. long time smoker and i live in spain. Started germination of 6 seeds last night and by this morning 4 of the seeds had split so iv planted them in medium soil and added water. My question is do i now put these babies in direct sunlight, non direct sunlight or carry on leaving them in the dark until they sprout and the second set of leaves have come tru.

If light is needed/not needed i was thinking about creating a propagator using a an old platic bottle, should i be putting small holes in the bottle to increase air flow or not as i dnt wnt the seeds to rott?

Many thanks!
