Ok, I’ve been using PAR as my light meter reading during my grows. Now I’m learning about DLI. So, does it really matter which measurement unit you should use? I just read this. How much DLI do Autoflowers need? “For Autoflowering plants the typical light cycle is 20 hours on and 4 hours off. This…

Cannabis requires the same DLI whether it’s auto or photo.

Awesome. Intense but great info. I’ve been using Photone but only for PAR. So now it’s on to DLI. The chart is exactly what I was looking for. Thanks.

DLI is where it’s at. The Photone app will give you DLI instantly if it runs correctly on your phone. It makes setting the intensity and height of your lights so simple. From everything I’ve read optimal DLI for seedlings is 10-20, veg 20-40 and flower 40-65. You can run the lights at less intensity…

I was about to make a post about this very question. I have read the original post about Dli and have been using the photone app for Dli. My question is, do we disregard wattage, ppfd, and lux and just focus on DLI? I can lower my lights and increase my DLI but what if my ppfd and etc are higher tha…

This is my first run indoors. From what I’ve read DLI is key. In my limited experience when I get the proper DLI the PAR is always in the suggested range as well. My ladies just entered veg (literally day 1) and are at 22 DLI. I’ll dial it up to 40 slowly.

I get why you said that but let me throw a monkey wrench into it. I grow 12/12 from start to finish. I disagree that Autos don’t care about a light schedule. Because i am extremely consistent of getting 1 to 2 oz dried, cured and no stems. I feel the 12/12 hurts Autos. I haven’t ran one at 18/6 bu…

Couldn’t agree more. My autos have been on 18/6 since day one. I’ll probably try 20/4 and 24/0 some time, but I’ll never run autos anything under 18/6.

I’ve got nowhere near enough experience to argue that for a second. As far as numbers and research goes it makes sense to me that if a plant can only take so much photosynthesis per day, that full is full. If it can be achieved with light over 18 hours, or more intense to match for 12 hours, that f…

@Underthestairs I have killer lights so that is not an issue for me. Example: I run HLG lights at full power. [image] [image] With experience, you will gain a lot of insight. I used to believe Autos don’t care about light schedule and now I fully disagree. Because different strains still had th…
