Can you make a flowhood with a ulpa filter? Anybody here done it? Sounds like its better than a hepa for around the same price

You can. It isn't really necessary, as the size of the most commonly encountered contaminants fall within the efficiency range of HEPA filters, typically 99.99" at .3 microns, I believe. ULPA filters are more efficient at filtering even smaller particles. If you can get an ULPA filter for the same price that is great, but the question then becomes - How much more resistance do ULPAs produce than HEPAs? The greater the resistance, the more powerful your fan will need to be. That means higher costs, typically. The money spent on the gear necessary for an ULPA could rather be spent on a larger HEPA. HEPAs are pretty standard for the purposes of mycology.
