never enough space.All the info you see about fans,air moverment they'll tell you to have you fans on the plants so the plants are moving but this is info has been coming to us for 50yrs and things are different with led,s.The leaf surface temp needs to be higher with led,s due to the lack of infrared.The surface temp wants to be around 29-30 and the air is around 2 high than the leaf so have your fan blowing the air over the top and not directly on the plant.If the leaves want 29 then the air should be 1-2 higher.If you end up with some really thick fat buds during the last 2wks then maybe move them down a little but they should be fine over the top.Most people have no idea about this.MAXIBRIGHT LED site DAYLIGHT.COM have some great info on leds.SANLIGHT.COM also have so good info on their blog as well.Theres a good phone app to measure light "PPFD Metre".You can run your light lower during the seedling and veg stage and only turn up full during mid flower.I use infrared thermometer to measure my leaf temps.I paid around £15 for mine but you can get them cheaper off temu.
