Narrative:

Hi Key! Atila in here. Sol 4 was a very busy day at the Green Hab (GH).

Ok, so let’s start with some crazy data about the GH today:

Time	08:54	11:52	13:30	17:15
Temperature inside (°C)	29	35.5	38	14
Temperature outside (°C)	5	13	14	8
% Humidity	16	16	16	21

*The times in red were when I watered the seed that is still in the lab, they are supposed to be someone else experiment.

Shannon told me to water the seeds 3 times every day, but by 18:00 they were pretty wet, I don’t want them to rot.

On the noon it was extremely hot, jeez! I had to take my shirt off for a while. I was alone, so I guess it wasn’t that weird.

As I told Sylvain on Sol 3, today I re-labeled all the seeds from the former experiment, it was a mess. Now the seeds look great, I didn’t group them, so they still have the random distribution.

I didn’t have enough time to rearrange the GH because I started my experiment today. I’m going to measure the germination percentage and rate of quinoa, amaranthus and two kinds of mustard on a control soil and the mars analog soil. I’ll attach you a picture of the pots. I still have to finish planting the seed I’m going to put on the growth chamber that’s in the Lab. I’m aiming to finish it before dinner.

Also, I’m aiming to make the GH great again by tomorrow afternoon, I’ll let you know how that worked.

Sol 5 was a pretty lazy day at the Green Hab (GH). Yesterday I worked till 22:00 at the GH and then I was looking for some guides to build a homemade Drip Irrigation System, so I woke up pretty late, plus we had the training for the Rovers and the ATV’s and a 3-hour EVA. It all went awesome! But I didn’t have time to make the repairs I wanted to make on the GH. However, I did repair the GH door that I discovered was a bit lose.

During the last hours of Sol 4, I finished the preparations for my project. Half of the seeds remain at the GH; the other half is in the growing chamber that’s on the Lab. For all the experiment I’m using less than a liter of distillated water per day.

The project wants to prove that Peruvian native crops can, indeed, germinate and grow on Mars soil. I’m working with quinoa, amaranthus and mustard (as a control).

I’ll attach you a picture of the pots!

As I’m aiming every Sol, tomorrow I’m going to rearrange all the GH, because it’s a mess. I’ll let you know how that worked.

Support/supplies needed: none
