I’ve come to realize that my conical and carboys scattered throughout my house was not only getting annoying, but it isn’t very consistent when it comes to fermentation temperatures. I had been looking on Craigslist the past few months and ended up getting a non-working Rock Star fridge with clear doors. A friend of mine said he could re-fill it and I picked it up.
Shortly after, I came across an add for some lab-grade temperature/humidity/light controlled chambers. They’re made by a company Conviron who specializes in these chambers. I messaged the seller and inquired a little, but the Ad ended. After tracking them down through another ad, it ended up they were right down the street. She sent me the manuals and specs and I realized how great they’d be for not only fermentation, but also another hobby I had tried before, Growing Shiitake mushrooms. They were asking $600 and I got her down to $300 each.
I went by to make arrangements to pick one up and these things were indeed gigantic. They’re over 6′ tall, 36″ deep and 30″ wide. There’s a touchscreen control that allows you to program to turn on and off lights, adjust humidity and temperature according to a schedule. They were in good shape and came with all their racks. Initially I only wanted one, but after going over there, it seemed that one of them didn’t run right. I took a gamble and offered $400 for both a working one and the non-working one thinking I could fix it.
They’ll fit 5 carboys in each, and if I put in shelving (would be a bit heavy for the shelf though), maybe even 10 carboys. I figure the second one would be for cheese, meet and growing mushrooms.
I got them home and tried working on the non-working one first. The motherboard had shorted and blown several chips off the board. It wasn’t likely salvagable and it was over 10 years old. There was no chance for getting it back to it’s previous condition. I figure I’ll slowly work on this one and install a Raspberry pi, PID controller and a couple SSR’s to control the cooling and heating system.
The other one works great and regulates temperature and light perfectly. These will be put to good use and hopefully end up saving room in the house!
