How fast does MgSO4 absorb water from the air?
This is a great question, and unfortunately, I don't have an answer for you.
My first instinct would be to question how well you heated the material and under what conditions. Insufficient heating would mean that you might still have water remaining in the material.
Anhydrous, powdered magnesium sulfate will absorb water relatively quickly at ambient conditions, though it will depend on the temperature of the solid, how anhydrous it is and the humidity of the air. Something more to consider is that the crystalline form will absorb water at a slower rate. Were you dealing with powder or crystals?
Unfortunately, it isn't possible to judge the kinetics without more information. Perhaps you can provide your procedure?

H2O in humid environment with respect to time. Granted, they are using a powdered form of the monohydrate salt, but I think it is fair to say the results would be similar. More
Great, thanks. The following paper should help to answer your question. Their procedure, by coincidence, is actually quite similar to the procedure you performed. Figure 2 gives a nice idea of what happens to More
