Rick, that's a lovely new acquisition. Although it's genes are each 1/3 rothschildianum, wilhelminae and sanderianum, this plant is clearly dominated by P. sanderianum genes.
Had a look at Hilo Farm's homepage and saw they are only wholesaler. Did you order plenty of them?
That's vinyl sheeting I bought back in 89 when I first built the greenhouse and made stacked benches to increase my growing space. It gets pretty damn ugly but has never failed. It funnels the water off both ends of the benches preventing the plants below from getting unintentional waterings.
