I am currently growing some tomato and chili seeds under a commercial grow light and I’ve recently bought some LEDs which I intend to use to build bigger grow lights. After some consideration of how exactly I’m going to set everything up and photographing the plants every day I’ve come to a rather obvious conclusion. 99% of the light is not hitting the little seedlings but rather the dirt around them.
After this profound insight I started looking around for grow light system which only illuminates the plants by using LEDs very close to the plants and automatically adjust both light level and the height of the fixture but I have been unable to find any such thing (probably searching for the wrong terms). Does anyone here know of such a system/project or do I have to design everything from scratch? Feels like something which should exist since the majority of the cost of running many grow lights is the electricity bill and not the cost of the light itself.
