Over one week, the germination rate in a variety of seed species was tested between seeds with and without testa. Particular species of seeds provided evidence of fast germination while others did not. Visual analysis sees no significant difference between the germination rates of seeds with or without testa. The germination rate of seeds with testa is equal to the germination rate of seeds without a testa. Uncertainties in our experiment include meeting optimal germination environments, as well as the uneven distribution of water to the seeds.
Furthermore, a small sample size experiment increases the likelihood of falsely accepting the null hypothesis. Future questions that can be asked to follow up on our experiment include whether pH or external factors such as soil conditions, temperature, and fertilizers affect the germination rate. These questions would lead the experiment towards figuring out how optimal germination rates vary by seed species.

You could try to combine the last two sentences to make the paragraph flow better.
Even though "tested" and
Even though "tested" and "testa" do not mean the same thing, their root words are the same. So to make the first sentence flow better, you could find a replacement for the word "tested" - like "determined" or "analyzed"
Wordy
"Furthermore, a small sample size experiment increases the likelihood of falsely accepting the null hypothesis." seems a little wordy, I think you could simplify this a bit further.
