hi , yeah i have also heard and read about tree top growing, too much like hard work if you ask me, but its ok i supose if you need the privacy away from priying eyes, i have seen pics of a huge bucket on a purpose built platform sitting high in a tree top, the bucket is sealed, apart fom a hole in the top big enough to allow full growth of the plant, the bucket is complete free of drainage, in the bottom of the bucket is about 4/5 inches of coarse gravel, this is the only drainage the plant gets, the bucket has a hose pipe conected to it at the bottom, inside the hose is a fat wick, the sort you might find in a oil lamp, the hose is tied to the tree and hidden behind creepers and ivy, at the bottom of the tree there is another bucket buried deep enough to hide it, there is a hand pump conected to it, i think the idea is that the bottom bucket is a resivoir, the hose and its wick are conected tightly, the pump will pump water and nutes up in a hurry, and when its not poss to water them freely, the wick sends water up in a cappilery action just like it would in a oil lamp, it looked crude but according to its owner it worked well, he grew this way becourse he had know light, and growing it at the top of the tree gave the plant all the light it needs.
............ peace ,,,,,,,,,,,,,, happy
