Pretty good; I never got around to building mine either as I simply don't have the time to do it... I ended up having to spend all that time repairing damage to my rental unit and finding new [better] tenants... and now I have to renovate my own unit in preparation for putting my house on the market next summer, or renting it fully... what a freaking nightmare... I have no time to do anything fun any more, wtf, I hate being a grownup, f'real.
If you have the time just toss together a simple hoophouse... cheapcheap.
