Here's 1 for under a dollar! Go to the deli & buy a 1lb deli cup & an 8ounce cup! The 1lb cup i cut a round hole in the bottom. The 8ounce I put a pin hole in! Start out with a small hole first, you can always make it bigger! Set the 8 oz cup inside the 1lb cup, fill 8oz with water & set on top of screen Cage & let drip on plants! I use a mistking mister but sometimes use the deli cup method to!
