First, hops are a vine and they will get very long and want to clmb. When they grow them commercially they have very tall poles (30 feet high?) with strings attached for the vines to climb on. I have seen people grow them and train them across a clotheslne setup. Those of us who live in communities with associations need to be aware of this as you might get complaints depending on what you build and what the rules are.
Second, when you grow your own hops you have no way to know what the AA% is unless you send some out to a lab and have them tested. For most people growing hops at home thats going to be cost-prohibitive. Different varieties are in different ranges but it will vary year to year and as we have all seen, can vary greatly year to year. So its always been recommended to buy your bittering hops with known AA% and if you are going to grow hops to grow your flavor and or aroma varities. So I would use that as a bigger consideration what varity you want to plant. Aroma or dual use varieties would make the most sense. And base that on what you like to brew.
I’m going to just say I’ve tried it in the past and found for me it wasn’t worth it.
