Ok.. i did the coke bottle thing. I cut the threaded part off and heated up a phillips screwdriver on my stove to melt several holes in the lower part of the dome to let air circulate a little. Im trying to think of a way to keep some water attached to the sides of the dome to keep the humidity up more than just evaporation of water from the soil. Any ideas? My environment monitor wont fit in with the cup so I cant tell what the actual temp and humidity is inside the dome, so Ill either have to get one that has a wire or just trust its going to work right and not be too humid as well. I really hope Josie the 3rd doesnt stretch too much with the light so high above the top.
