Using hlg scorpion, first time for veging seedlings had dimmed about as low as it would go about 6000 par uped a hair to about 8000 as they were looking a bit leggy, slept for 4 hours & my 2 best seedlings were near dead, main stems tread thin, bad mistake I guess, is it wise to use this to veg at all? I could move in my old SF-2000 lights for veg but the scorpion is so heavy I hate to move it.
Mine is not the D just plain S, I went from just under 100w to about 120w with new week old seedings and it baked them in 4 hours.
I used mine for the seedlings in my current grow. But it was like 6 feet above the cups which were set off to the side and not directly under light. I also had it dimmed all the way down. I wouldn’t recommend for seedlings, but I made it work. Only reason I used it was the room it’s in is the only room I could control the environment in the middle of winter.
I suppose I should raise, I have at about half that height, dimmed to 68w from the wall presently, using for garden starts as well.
heard good things about it (DudeGrow.com ) ( they b offer a discount also) myself like the LED;'s from budget Led's which was re-named Elevated Lighting gret light , these are rated #10 - USA made and by vets !!!
Got mine for $765 about a year ago from Growlight Heaven.
