I just got a bird feeder. It's a plastic tube only about 4"

People also use lanterns and glass candle tubes. I saw big candle tubes at WalMart for $15-20, they might be big enough for an mh. The ones at walmart were a little fancy, if you shop around you should be able to find something a little cheaper/simpler to use
Cornelius Reviewed by Cornelius on . homemade cool tube for MH i just made a homemade cool tube for my HPS from a bake a round pyrex thing. from Zandors idea in the FAQ. it is a really good idea problem is that a MH is a way bigger bulb and dosn't fit in the 3.5 inch bake a round. Has anone else made cool tubes from other things? any suggestions of how to make one? thanks Rating: 5
