Airlock question

Hello I recently purchased the $99.00 starter kit as I was going through all of my equipment my cap for the airlock was misplaced I went ahead and started my first batch od block party amber ale. Do I need the cap for my airlock or can I continue the process without?

The cap is for keeping fruit flies from trying to swim through or infect the contents of air lock. Wrap a piece of plastic wrap around the top of the airlock and make a few pin holes in it for CO2 to escape.

Thank you I am really looking forward to tasting my first batch its something that I’ve wanted to do for a long time.

Are you set up for controlling the temperature of the beer inside the fermentor? If you would be using US-05 or WY 1056 the ideal temp of the fermenting beer is 65° to 68°F.
