Applications are accepted on an ongoing basis. Apply here
Each state has its own time frames for accepting dispensary licensing. Some are always receiving applications and others have specific time windows for applications. If there is a specific time window you want to make sure to prepare your application in-time so you don't miss the deadline!
Thankfully, though Colorado does have a very involved application process for dispensary licenses, it does not have a specific timeline for applying. One thing to keep in mind in Colorado is that there are a lot of dispensaries and business competition is high!
