Someone on here told me about this app. My first readings were between 80 and 90 pretty consistently over the canopy. From what I understand I want them to be in the 40 to 50 range during flowering. So now what? I need to lower my light intensity right? ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/8/4/4/844a5b18216e26940816ceb9d4b8742dc6db5a9f.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/b/1/2/b12d4ac695d3b01ebc6f3e8e038c452e3ecb9bef.jpeg) On a side note. Can this free ebook dot get placed somewhere else? ---

If your girls arent used to that kind of intensity, then ease em into it. I started my girls out at mid 30s DLI with 700ppfd and over two weeks time will gradually build them to the 40s around 1000ppfd ![20230421_202106](https://global.discourse-cdn.com/growingmarijuana/original/4X/7/f/b/7fb80360c9870a0f8c87a76f2952a47b7333112c.jpeg) ---

They have been at this intensity for weeks. So I should turn it back down in intervals? Great grow space! Plenty of room! ---

Alrighty. With apple you need a light filter to use light apps. I was sorta worried about those DLI numbers. I cant remember what theyre called but i think its a piece of paper. @MidwestGuy do you know? @BudzMS@Bunger64 ---
