Pretty much the exact same process as cycling with fish, but using pure ammonia to dose per day. Crushed fish flakes will work fine as well though, if you won't bother purchasing ammonia.
Main thing to remember is to keep the aquarium lights off the entire cycle to prevent a huge algae bloom. Algae are plants, so need nutrients and lights to grow. If you don't give them light, there won't be much algae.
In the end, same as cycling with fish, do a 40~50% water change per day for 2 days. Don't perform 100% water changes at this time, because it may kill a portion of the newly cultured bacteria.
And I'm sure you know this already, but thought I'd mention, to test with the API master test kit and not test strips.
Good luck-
