I agree whole heardedly with CheckThoseTrichs... It's about ppfd. Lux has not a whole lot to do with anything and on an impressive light setup like that use the ppfd thing..

@checkthosetrichs so the 350 to 650 range would be the best for the seedlings??? Damn, seams close, but who am I to argue, this my first time haha! Thanks for the help!!!

Awesome you included the PPFD specs! I wouldn't base it off of lumens...as PPFD is what the plants see and lumens is only what the human eye see's in white colour. For veg I would keep it at 300-650 PPFD depending on how young it is which is in the 16"-24" range. For flower I would keep it above 650 PPFD which would be roughly 12" or closer. Some people also gradually lower the light until their plants start 'praying' towards the light. Cheers and good luck

get a free lux meter on your phone and then set the light distance to get close to the following :) HOW MUCH LIGHT DO YOUR CANNABIS PLANTS REQUIRE? Clones and seedlings: 5,000–7,000 lux Vegetative growth: 15,000–50,000 lux Flowering: 45,000–65,000 lux Maximum recommended amount of light: 75,000 lux

Hey, with the distance for light to seedling I try and set up around 24 inches apart. You don’t want to go too far away as the LED lights won’t reach the seedlings and their first set of leaves. You want to be close enough so the leaves can absorb the energy. Hope that helps and happy growing
