@Vt_Kind thanks for the reply, the light is at 75% at 25 inches now 18 days old, I have 5 plants 3 gallon under this light in 4x4, so it's tricky to get them all positioned correctly, as the biggest plant is now the smallest cause its the one at the edge of the light, so maybe if i increase the distance to 30 inches and set it to 90% or 100% might help cover all plants? or I might just Increase the light at the current distance, no clue what I'm doing, happy grow, and any videos and info. regarding this light is much appreciated.

@Jelka, Hi, When I upped the light to 100% the only issue I had was the plants got almost to bushy with the nodes growing really close together, so much so leaves were kind of interweaving. I had no light burn issues at 24 inches above the plants, so maybe putting the light higher up or dialing it back 10% might have made the nodes spaced a little farther apart but the plants made it just fine. I haven't had any experiance with Spiderfarmer lights but the Sonofarm seems to be a great light. Its now sitting only 16 inches from the tallest tops, since i ran out of adjustment with the way i have it set up. Since it didnt seem to cause any problems i decided to wait until the plants finish before i modify the way the light is hung now so i can raise it higher for future grows. I do want to compare my 600w hps to the Sonofarm at some point as i haven't had an issue free grow with the hps to be able to compare it to this crop with the Sono which has been my best grow to date.
