Hi I'm Stan DeFreitas, Mr. Green Thumb. Where do plants get their energy from? Well through the process of photosynthesis. We talked about the energy of photo in light, synthesis meaning putting together. Plants build energy through this miracle of being able to produce energy in the foliage. Simple sugars is developed through oxygen, hydrogen, carbon, nitrogen, phosphorus, potassium, all those elements that we have all get used by the plants and the plants starts to develop energy in the foliage. Remember plants that are inside have large leaves normally and they're trying to develop more energy on lower light. The more light the plant gets, often the foliage can be a little bit denser and a little bit smaller. In general the plants inside have to have real large leaves so they can produce as much energy as they can from reduced light. All energy is produced in the plant from light so give the plant as much light as you can in most cases. Some of your foliage plants that haven't adapted to low light conditions well you can kind of ween them off and put them in a darker area of your home and they'll still survive.
