"Nice and easy to assemble, creating a nice strong union. I grow my vining tomatoes up strings, and they easily reach 10 feet in height each year. I have used PVC pipe in the past but it was less than ideal - often popping loose (have to leave the joints unglued so I can disassemble in autumn) - but now it should be just fine. I drape 40% shade cloth over the top in the summer to keep the leaves from scorching in the Texas heat. I'm ready to start the next build..." - Jay
