Once the seedlings looked more like plants, the next step before planting out is to get them hardy. This is a process where you put the plants outside during the day to get them used to the temperature but bring them in at night because it would be too cold for them.
This tends to take about a week. If you don't go through this process your plants might die of the shock of being moved into a different temperature, light or wind. It is best to put your plants out of the harsh winds or strong sunlight. We put ours outside the Food classroom, it was rather windy there but this was the best place we had available to us. But thankfully the plants survived this process and could then be planted out into JPa's plot.
