I do believe I am going to see if I can trigger flowering today. What should I set the light intensity at? Also is everyone pretty much in agreement with 12/12 being the right setting?

12/12 is a go. I dont change intensity until I see flowers. But the Photone app can help set DLI

[image] Start using DLI Lighting Daily Light Interval (DLI) is a quick and efficient way to calculate how much light our plants are receiving within a 24hr period, allowing for easy light adjustments. DLI will help you and the community to better understand your lighting i…

These guys got you covered. Photone and DLI will take all the guesswork out of lighting. Stay with the manufacturer suggested heights and tune intensity to get the right DLI. Adjust intensity up or down a little based on how your plants respond.

I use DLI for the light measurements. When you flip to 12 hours from 18 and leave the light output the same level. The DLI will drop to about 65% of it was at 18 hours. Here is a chart for recommended DLI during different plant stages. And a chart that I made to read the DLI under my HLG Diablo boar…

12/12 a go like the other growmies said. since your changing schedule i would say it’s a safe bet they’re photos This chart will be helpful for setting DLI correctly. [image] And recommended ppfd values For regular weed growing, the PPFD for seedling stage is 100-300 µMol/m2/S; the PPFD for ve…

12/12 unless you have something like a Haze Sativa or other equatorial Sativa’s in that case you want 11 on 13 off

OK, a question to midwestGuy and everyone on the board. What is a good light meter that can also measure and or calculate DLI?

Many download the Photone Grow Light Meter to there phone. If you want to spend $$ go to Apogee Instruments. If you watch youtube light reviews many will be using Apogee meters. Truthfully if you have a light that has published ppfd maps you can get close enough based on distance and the map. If…

I use the Photone app on my iPhone. It works fairly well for the price. It will read in Lux, PPFD, and DLI, and it reads the DLI of my older lights well. But with the Diablo I read the light at the canopy top in Lux, and use the previous posted chart to obtain the correct DLI.

Photone app vs apogee meter. [image] Start using DLI Lighting Results are in, I was impressed with the Photone app, pretty close to the Apogee when a diffuser is used, totally wack without a diffuser. Starting with the Apogee SQ-626 in the flowering tent [image] Get a…
