gracious o wise one!

I will look into the pvc intake thing but it will be difficult as i have already 6 huge holes to cover. Luv the instructions by the way.

if i still go for the slit in the light proof material and have a rim placed along/above the holes (so the sheet is kinda sitting like a cat flap over the holes-the rim will allow air to seep through ..the little light that is gonna leak in...will that destroy the dark cycle? im planning on haveing black tights/stockings on the outside of the holes to act as filter (may also lessen the amount of light going in)

i kno u gave ur answer as going for the pipes but any suggestions about my original idea?

cheers for ur help jamster
