Running a vivosun 1000w led grow light, and curious about how bright I should be running it for sprouts and how do i know when i need to raise or lower the brightness? First time indoor grower. Growing 2 plants is a 2x2 zeny grow tent.
I use photone and set my light for 8Dli for the 1st few days then increase it to 10Dli for a week and keep increasing every week until I get the plant to take about 35/40dli. That is from my phone, its took me a while to find the sweet spot for my lights. It takes a few grows to figure out what the plants can and can't take at various stages of the grow.
If you have a smart phone download yourself a ppfd meter app, such as photone. That way you can measure the light in either ppfd, DLI, or lux and you will know how much light you are giving your plant. A seedling only wants around 150 ppfd.
Vivosun does not have a 1000 watt led lamp. Look at their official website, search for your model led and check the manual with all the specific information and instructions about your lamp.
