Another Las Vegan here, taking a stab at growing hops.
I live in a condo/townhouse so no yard. I have two rhizomes planted in containers on my east-facing balcony. The shade hits at just about noon, so (provided I can sustain something) the plants will be shaded during the hottest part of the day. I plan to run the vines mostly horizontally on a couple lattices around the edge of the balcony.
One of the containers is a 1/2 whiskey barrel. I think it's like 20 gallons. The other container is definitely too small, probably closer to 5 gallons. But I already had it and didn't want to buy a ton of stuff not knowing if I can even do this successfully. If they live through the summer I will get another barrel and transplant. I planted two Cascade rhizomes this past Friday (purchased from freshops.com), and both containers sprouted today.
I set up a very-DIY drip irrigation system. I took a couple water bottles and jugs of various sizes and poked a bunch of holes at different levels, and buried them in the containers to different depths. The clear bottles actually give a pretty good glimpse of the moisture content of the substrate.
I have been watering like crazy. Two or three times a day and we haven't even cracked 100 yet. When the sprouts get to a trainable height I'm going to add two or three inches of mulch to help with moisture retention.
I will try to update, and if I can keep anything alive or get anything growing I'll post some pics.
