To start plants a wick is placed in the pillow with a seed glued to it, then an astronaut waters it every day. The pillow evenly distributes the fertilizer. In order to make sure the plants have one up and one down, LED lights are put in place at a fixed point above the plants. The lights act as the light stimuli and so the plants grow towards them. ]]> 2020-03-10 15:27:37 UTC https://padlet.com/1201896/amki370gkcqz/wish/457678717 1201896 https://padlet.com/1201896/amki370gkcqz/wish/457692797 Experimenting on plants in space started in 1999 when Anna-Lisa Paul and Robert Ferl sent their first experiment to the ISS on space shuttle Columbia from there it has continued and grown.]]> 2020-03-10 15:42:23 UTC https://padlet.com/1201896/amki370gkcqz/wish/457692797 1201896 https://padlet.com/1201896/amki370gkcqz/wish/457698916 Charles Darwin and his son Francis conducted some of the earliest phototropism experiments. Phototropism is the growth of a plant to or from a light stimuli, meaning that if a plant is placed away from a light source it will grow towards it or away from it.]]> 2020-03-10 15:48:46 UTC https://padlet.com/1201896/amki370gkcqz/wish/457698916 1201896 https://padlet.com/1201896/amki370gkcqz/wish/459247475 2020-03-12 15:23:36 UTC https://padlet.com/1201896/amki370gkcqz/wish/459247475 1201896 https://padlet.com/1201896/amki370gkcqz/wish/459250396 2020-03-12 15:26:18 UTC https://padlet.com/1201896/amki370gkcqz/wish/459250396
