How to light up flower hours

To flower 12/12 18/6 19/5 20/4 24/0 My girls have been vegging for 14 weeks and I now have hopefully got some lights that will work.(upload://39X46VBKmzzjklkziWovNkSVF6h.jpeg)

(upload://gOLE1zVHrBsjC30YQMM1TRiX4X3.jpeg) The PPFD readings were 790 and DLI were 65-70 so I turned the LED down and rasied up the lights and 18/6 they are at right now.

14 weeks? 12/12 for flower, all the other light schedules are for veg. :thinking:


Thanks I can change that 12/12

Have fun!

790 X 3600x24 /1000000 = 68DLI
12 hour flower schedule will bring DLI to 34 which is about where you want it

How did you get the 790 PPFD? Manufacturers PPFD map?. Is it the average over the footprint or a single point? Curious


center point on the canopy I will switch it 12/12

You want to take an average of the entire space. Not just the center.


The whole area 9 points were high and so I switched to 12/12 lighting and see what happens.Plants are spread under the lights better now
