Time constraints

My trial experiment is the one where I tested the brine shrimp but they refused to hatch up till the 2nd or 3rd attempt where they finally appeared from their cysts! Afterwards, I carried out my actual experiment twice. However, due to time constraints, I am unable to carry it out a third time! The ideal was to carry out the experiment 5 times. If I were able to do this experiment again, I would carry out each set-up more times to increase consistency of data and reliability of results. This is one limitation of my experiment.
