Carboy cap for 1 Gallon carboy

[lolcats]

Stupid question, do they exist anywhere for 1 gallon carboys? I can only find the orange caps for >3 gallon carboys.

I'm trying to build this

The only thing to my knowledge you will find for one gallon are those plastic opaque caps with the hole in the center for the blow off tube.

Thanks for the response

So what do you recommend using to replace the 1 gallon jar/2 holed lid in this set up

You can, however, ferment 1 gallon batches in a 3 gallon Brew Demon conical like the article shows being used. It would also give you room to increase your batch size down the road if you choose to.
