It funny you should post this as I was thinking about this last night after ordering the wine cooler. When I first started lurking over at puff last fall I decided to go against everyone's advice and bout the smallest box I could find. figured I'd line it with spanish cedar and it'd be all I ever need. Then my first order showed up and I had to buy a large hinged jar instead so I could fit everything in. Problem with that was when my next order showed up I was in need of another. Then another. Then couldn't keep the infused in with the rest so I needed another. Now I'm contemplating some box purchases and tired of buying jars so I decided to jump both feet into a wineador. That should be all the space I ever need... right???
Humidity, I bought a %72 boveda to start with. Thinking that %70 was a good starting point and with the lack of humidity here in Saskatchewan the %72 would be good. I found my sticks had a lot of burn issues so I jumped down to %62's when I started multiple humi-jars. Now for the wineador I'm going to give the %65 HF bead's a go.
As for accessories I started out with a sharpened .308 casing (from my first white tail) and an old zippo. I wanted to give a guillotine cutter a go and bought a 50 cent single blade along with an order and that quickly found it's way to the trash. I ordered a nice spanish cedar cigar sleeve that I rarely use since I rarely smoke away from home. Then needed storage for travel so bought a setup from cheaphumidors that came with a 4 cigar caddy, torch lighter and dual blade cutter. the cutter still seems to maul the cigars a bit but its light years ahead of the single blade. Along with my new pipe smoker trade I was gifted a nice xikar torch lighter. I'll be on the search for a v cut here soon. Really want to give one a go.
As for lessons I've learned,
Want a 50 count humi go 100, want a 100 go 250, better to have more space than not enough.
Rely on the BOTL's knowledge and experience, I've learned more from the fine folks here than I could in a lifetime on google.
Research and try before buying large quantities.
Don't listen to me, I'm usually just guessing.
