Im new to LED setup and growing in general and I have a question that Im confused about.
Manufacture advice on LED installation is to keep 24” inch between plant and LED. However, after doing so I tested the luminous and its only around 10K Lux. Now I read somewhere a minimum of 15K lux is required for healthy veg.
Should I bring the light closer to the plant and risk a light burn?
Should I keep it as is to stretch or not having enough luminous for healthy growth?
I’m in the process of researching this and apperanelty I should forget about Lux when using LED since it only target specific spectrum and I should focus on total power drawn.
I think 10000 lux is very low. Full sun is about 120000 lux! Most authorities say cannabis can’t use any more than 85000 lux without adding CO2. One problem with having the lights close is say you get 40000 lux at 10 inches. Then at 20 inches it will be 10000 lux, because of the inverse square law. So better to have more/stronger lights at more distance for more even lux.
@1BigFella 10000 is low but it it how i determine my light height, 10000 is my minimum. Any less and i drop lights. It is a cheap lux analog meter but gives me an idea of where im at. Also i am almst all cfl and about 125watts of led
Also i am not shy about the cfls lol i use a good number of them, and also added on to my led fixture with some lower K’s for flower power.
BUT…I AM SAVING FOR QUANTOM BOARDS
Those i will have for round 3, along with a few new strains i cant wait.
I have a 400watt hps i picked up the other from a friend of mine. He gave it to me for free, i just need to go to town and get a new bulb and plan on added that to my room for rest of flowering
Does the lighting during veg impacts the finale yeild and quality !? Because Im currently searching for a better LED for flowering now and future grows , please let me know what do you think?
