LUX meter grow question

dauntless
dauntlessstarted grow question 3 years ago
Can someone check out the LUX meter video and tell me how I should be positioning my lights? I think maybe I have too much light on them. My meter says 600 (x100) that puts me at like 60000 lumen. The converter I used put that to 1541.36 umol/s/m2 which is a lot of light already

Idk which meter you are using. But because you are using leds and hids they have different wave lengths and you need a meter that you can get 2 dif readings off and then add them 2gether to get a true ppfd map. Here's what I'm talking about. Use this and it'll give you a proper lux reading. As 60000 lumen from a high led light is only in the 800 range. And the SF1000 is only rated in that range, but you are using another light with a dif wave length. Good luck

You want to position the probe level with the canopy, that's the reading you want because that's what the plants getting. If its to strong either lift lights away or dim light power until you hit the reading your happy with.
