I'm not familiar with that Tigridia, but many species are relatively
high-altitude, cool-growing summer plants. If they get too hot, that is the
end. At higher elevations, air temperatures where other species grow can be
in the 25-32C / 78-90 F range. Nights even in the summer may require a
heavy jacket. However, they grow in the ground, where soil is not exposed
to heat, as would be the case in a small seedling container.

If I keep watering Ferraria crispa seedlings, they remain in leaf until
temperatures get in the 32C / 90 F range. Then they go dormant. Even small
ones are surprisingly strong, and come back next fall. In your situation I
would keep watering until they begin to yellow on their own.
