How To Use Photone for Optimal Lighting

There are many ways that Photone can help you to achieve optimal lighting for your plants. Here are a few ways on how to achieve that. Please note that it is not done with just an optimal amount of light: Plants will also need the right amount of water, nutrients, and more to achieve best results.

Take Measurements With Photone

Regardless of which measurement you want to take, make sure that you are using a diffuser and the correct light source setting. Additionally, place your phone at the correct distance to the light at the top of your plants' canopy. Doing so allows Photone to measure the light that falls on your plants' leaves.

Optimize Your Plants' Position

Our eyes are not very good in determining the absolute brightness of light. You may find it difficult to spot which window of your house lets in the most amount of light. Similar, your lights output will differ a lot if you measure right underneath it or in a corner of your grow area. Use the PAR Meter to measure different sectors in your grow area and place your plants accordingly.

Optimizing the DLI

Every type of plant has an optimal daily light integral (DLI). Look up your plant's DLI for your desired result such as maximizing yield. You can use the references provided in our DLI article, our blog, or look them up online. On the DLI measurement in Photone you can set how long your lights will be turned on. If unsure, choose the duration according to your plants' grow stage (seedling, vegetative, flowering) – usually it’s around 18hrs for seedling and vegetative, and 12hrs for flower. By varying the light intensity (power or height) you can achieve the DLI value that is optimal for your plant.

Manage Bulb Lifetime

Any light bulb has a limited lifespan – some more than others. Especially with any kind if HID light such as HPS, CMH or MH, the light output will drastically decrease within its lifetime. Some bulbs may even lose 80% of their light output during their specified lifecycle – all this whilst still consuming the same amount of energy. It is therefore crucial to manage your bulb lifetime accordingly in order to invest your money wisely.

By measuring the total light output with the PAR meter or Light Meter exactly in the same position and setting every few weeks, you can make sure to take an informed decision about replacing your bulbs.
