I'm going to do slight increases every few days to work it up to that neighborhood. My light really burned my first grow following the manufacturer's recommendations. It seems stronger then advertised. Unless some deficiency made them extra sensitive to the light. That is why I think I need to pay attention to PPFD this grow, am looking to not repeat the burnt cola leaves this time.
I been using that websites lux to ppfd convertor. According to the DLI calculator my plants are getting 39 at the top center of the plants. I have not researched DLI for cannabis yet, so i dont know if thats good or bad.Here is a DLI calculator ..

Yea I'm an android guy, but I have access to some expensive meters at work, their pretty good about borrowing stuff overnight.I don't know about the accuracy of those lux to ppfd charts, or the accuracy ofsome lux meters... if you have an iphone, photone has a great ppfd, dli, and lux app for a few bucks. The Migro dude checked it out and gave it a thumbs up for the iphone.
40 is the DLI for non co2 environment that is recommended, so that puts you right there.

Seedlings are born in plenty of sunlight naturally. I sprout them under a 240w at 80% and never had problems. After two week I run at 100% for maximum growthWay too much light for a seedling
