Question: How much sunlight is needed for plants to grow?
Hypothesis: A plant in the closet with total darkness will wilt. The one in the bathroom with indirect sunlight will slowly wilt and the one in the backyard with direct sunlight will grow.
Conclusion: If the plant does not have direct sunlight it will die. This plant needs a lot of sunlight to grow unless it is done growing. These plants already bloomed, therefore, I can not say after one week if the plant still needs to grow.
