Very cool! What is the mesh that you used? is it secured to the ground in any way? We have terrible storms here that will blow the outdoor cages over really easy!
im have two pothos ivy's and another hibiscus tree that i am going to put in there. the screen is poltry netting from home depot and it is secured with industrial zip ties. its not secured to anything but its pretty hardy. its 6 foot tall by 4 foot wide. i have double corner risers for vertical support. if it does fall over all the pvc is glued so it isnt coming apart !
i got the pipe from work along with the ellbows and tees. all i had to buy was the netting and it was 12.99 and it took 2 rolls. so, if all was bought at a local hardware store id say about 40 to 50 dollard total.
