Yeah really you should cover them with black plastic,tape or sunthin'! I tried the clear poly tubing and it was a nightmare!!!!!!!!! The fungus gnats wre terrible! They get in your medium lay eggs and your all of a sudden have a gnat farm! They love dead rotting leaves that fall or have been trimmed and kept in the room in a bag or what not.Next time use the black poly tubing to to keep the algae from forming inside the tubes and and around the plants base!Just a little info for ya!

Holla!
