I used the photone app in order to get these numbers that are pictured below ! I’m going to research them but I’d thought I’d share them anyway.

Phone app PPFD meters can work decently, I use one in my own grow to confirm hanging height, and reference it to the manufacturer stated PPFD for certain hanging heights (MIGROW is good about providing that information.) Your 46 PPFD for the 240 watt LED seems unbelievably low so I would look into that. Make sure the app adjusts for the correct light spectrum/colour of your particular light (eg. 4000k) and keep in mind your phone will measure from the camera on the some side as your screen, and not the one on the back. 200 PPFD for a young seedling, 400-500 for veg, and upwards of 700 in flower are the numbers I aim for. Happy growing!

You also need to have the paper diffuser on top of that light sensor to get accurate numbers. It is pretty accurate tho

Autoflower not flowering after 3 monthsI'm growing a dwarf auto-flowering strain in a greenhouse outdoors. Its now been 12 weeks since it sprouted and no sign of flowers. Someone else mentioned that autoflowers sometime switch to photoperiod outdoors. Is this a possible explanation or am I just being impatient?5y ago

Lighting. Increase or stay the same?Hi, I'm thinking about increasing lighting to 100%... is it too soon? Currently at 60% 20 inches away (manufacturers recommendation.)
I'm thinking 100% but staying at 20 inches away.. what's your thoughts? Too soon? (12" - 18" 100% for veg manufacturers guidelines)
