Replying to Screen Printing

I just got a screen so I could print on some shirts to drop with a video I've been working on for the fall, my problem is that I asked them to chemically harden it for printing with a water based ink because I heard good things about the durability of water based ink. Shortly after doing this I found out that the recommended way of curing water based ink is with a forced hot air machine that is very much out of my price range. Am I alright to use regular ink on a chemically hardened screen? If I were to just used the water based ink anyways would I be able to cure it with a heat gun or heat press?
