Should I switch my light to 100%

[johnbrown25]

Hey all, I have been in the flower stage for about 2 weeks, everything is going well but wondering if I should switch my light to 100%. Currently it’s at 75% and probably about 30-35 inches high. What determines when to switch to 100%?

The protone app for your phone is a great tool to help you understand the plants light intake needs. The app has a daily light calculator and a chart that shows recommended light levels throughout the plant growth cycle. It’s pretty cool!

Yeah crank it to 100% amigo.

Drop light down to around 12-18inches.

What light are you using?

I found it depends on your phone device...and not really that accurate... do you have anything to compare the app to an actual light meter??? Just curious as I have a Z fold 4 and it has 2 selfie cameras... each camera gives off different readings

Very simple imo, if they are praying before lights out yes, of not no

From my understanding it is pretty accurate with the new iPhones. Not sure about other devices. There is a British guy that goes in depth about it on YouTube

You bring up a good point Jkash. Seems if you’re an ISO user, the readings are more accurate comparing to an android device. In my experience and usage on a iPhone 15, the app seems accurate enough for what I’m trying to accomplish. I definitely accept the fact that the app will not be as accurate as a specialized ppfd device but I also have no need to spend that kind of money on a tool like that.

I have been aiming at week 4 of flower for max strength on my lights and feed but I'm stretching that to week 6 this grow, I enter flower at 60% and bump them up 5% ish per week along with my feed. At week 6 weeks my lights will be at 100% and plants will be receiving their max food - week 8 then I start to back down the light and food.

Nothing I grow goes less than 10 weeks then I start to pull 1 at a time and I let some go 12 weeks. It all depends on how pressed I am to get my vegging plants to go into flower. If I have the time I'll let them ripen in flower

My Spiderfarmer light has a manual, it says to go to 100% for flowering and haven't had any light burn with a 12" distance.
