Centaura,

I like to use the 2-mil clear plastic sold for drop cloth in paint stores. It's inexpensive, and semi-permeable: water vapor can't get thru it, but oxygen and CO2 can.

When the sphagnum starts to dry, I use a veterinary syringe (available at feed and farm-supply stores) to add a bit of water. The hole left by the needle is so small it can be ignored.

Hope this helps a bit.
