ROI-E 680, how high to mount it?

[Scarecrow1g]

Just got my ROI-E 680 in the mail the other day and I'm getting ready go start some auto flowers. My first time with auto flowers and also my first time with a good quality light. I'm planting the seeds directly into super soil in 5 gallon pots. I can't find any information on light height during the plants life cycle. All I can find online is 8-12 inches above the canopy. How high should I mount it at wash stage and should I keep it at 100% the whole time?

I start out around 2’ at first dimmed to 60%. That’s going from a roi e200 to roi e680.

None at all that explained height or intensity settings for different stages. Just how to setup the light.

The Growers Choice ROI-E680 fixtures have a known widespread issue of the drivers failing and turning on bars when they're supposed to be off. The company is well aware but hasn't sent out any notifications or recalls. This happens even with their branded digital controller. They don't care if your crop is severely damaged due to light pollution caused by their faulty drivers. They just released an "upgraded" ROI-E680S with drivers that supposedly work correctly it looks like they have less diodes though, so you'll be pushing them much harder to reach 680w. Also, they won't upgrade your old ROI-E680 fixture until you have photo or video proof of it failing. So pretty much you have to wait and catch it in action when these fixtures decide to wreck your medicine. Keep in mind they can turn on at ANY time throughout their off period. Tell your friends and family. Quality medicine is what we all strive for and this public service announcement is to continue this goal. I have many of these fixtures and feel betrayed by the company.
