300 Watt Grow Light Yield

Purchasing the proper grow light can be a hard task to take on. It gets a little more complicated when you have a small space to work with. According to growers and manufacturers, bigger is the best way to go. If you are on a budget or have limited grow space, A 300 Watt LED grow light can provide you between one and six plants. For better yield results, a maximum of two to three plants is recommended.

If you are using soil to grow, you can expect about 20% less yields than if you were growing hydroponically. Value comes in small packages. Think of light as food for your plant. Light is what the plants turn into energy through photosynthesis and this energy is what fuels vegetative and flowering growth of the plant .

The more light intensity your plants get, the better yield results you get. It is important to remember that yields also have a lot to do with the genetics and strain of the plant. When working with a 300 watt system, you typically want to use one light throughout the plant’s life. Be very careful not to shock your plants with light changes during the vegetative and blooming stages. This can stunt plant growth and bloom development in your plants.

Using one light will save you time and money. What creates the most value is the intensity and full spectrum of lights. Infrared, ultraviolet and par map. With that being said, most 300 watt panels are only about 130-150 watts. Do not be fooled by the rated watts of how many LED’s are in the grow panel.

If you want to know what yields are possible with your panel, figure out how many watts it is actually putting out. You get what you pay for so do not go cheap. Think of it as an investment that is going to provide you with better yields during the grow process of you crop.

Things to consider:

Full Spectrum LED lights – designed to mimic outdoor sun light.PAR – a measure of light emission within the photosynthetic range of 400-700nm. Intensity – amount of watts you are growing with.cycles – proper light intensity during each stage of the plant.
