Week 9b

12:00 p.m. - 1:00 p.m.

This week I recorded the highest and lowest temperatures outside and in the greenhouse.  I also recorded the day length - 6:31 a.m. to 6:56 p.m. - but did not have to adjust the growth chambers because apparently it was the same as the week previous.

Also, as Dr. McFarland was concerned that certain treatments would become too hot because they were covered in black plastic and metal tape, he covered the etiolation experiments that were located outside and in the greenhouse with two layers of white plastic bags.  This was done to keep the experiments cool.

White plastic bags were placed over the etiolation experiment outside to keep it cool.
