It’s not critical so long as you have a slight excess of acid. You will be adding more iron into solution anyways.
As long as metallic iron is present ferric will be reduced to ferrous in acid solution

Sorry but no. It’s so easy. I have purchased “copperas” from a fertilizer co-op store, took it home, and made up 20% sulfuric acid solution
added the brownish yellow iron salt and boiler with regular nails for about an hour or two and let it cool and got beautiful blue green crystals
