White widow autos, light distance?

Im growing 2 white widow auto seedlings, this is my first grow and I was needing advice on light distance.
I am running a Fecida CR600 130w/1000w equivalent AND 2 regular LED 3000k light bulbs. I try to keep it atleast 18 inches away. Any advice is appreciated. Thanks

So far so good. Keep buckets on risers so you can collect runoff to measure. You should have many holes for drainage on bottom and sides. On phone is an app PHOTONE. it measures for light distance and dli. Have fun


Thank you. Another question I have is about the fan. I have one big fan and both my seedlings do a (little jiggle) about every 2-3 seconds. Is that too much or too little ?
