Everything is outstanding about this light, took me a couple runs to learn how to use it. But if ur growing indoors in a tent then this light gets a lil warm on full blast. However 75% is plenty of light and usually only use this during flower and might turn it up for the last couple weeks of flower, so .. just a heads up.. 25% is great for seeds and veg.. i will turn it up to 50% around 6th week of veg. Also depending on stage, higher humidity, consistent and frequent watering will help with heat.. hope this helps, works for me! Im also an organic farmer..😁😎
