It is kind of sad because the Chinese POS lights get them every time. I might be into the Cadillac lights but there is nothing wrong with HLG's. I do not own one but it looks like they will produce decent smoke.
It really is just messed up, they all come on this site with there new tent and set up and there is that Burple light. The bummer is the 2 or 3 hundred they spent on the light and it is junk.

Use what you have. That part is not a problem. Many here use blurple leds for suplimental lighting. Those who do seem to think it adds something to the flower. If money is super tight right now (and it is for so many), use what you have for now, maybe add a 3000k LED light bulb like was previously suggested. Just try to get some white light in there. Hopefully money will not always be tight and simply make it a goal to upgrade your lighting as money permits.

TBH even throwing a few 3000-5000k light bulbs around that blurple would likely make a difference.

LED distance is based on a number of factors, including the light intensity, the age of the seedling, and how many lights there are.

Each plant can only eat so much every day. That's the DLI (Daily light interval). For cannabis, it's 65 MOL (Thanks @Anthem !) per square meter per day in flower, and roughly 40 for veg. The role of the light is to feed the plant, so you'll never reach DLI because that light is only partially feeding the plant. It's like trying to live by only eating bananas.

The importance of Daily Light Integral (DLI) for indoor cannabis cultivation

Daily light integral (DLI), represents the number of photosynthetically active photons that are delivered to a given space over the course of a day. Considering not all wavelengths of light…

Here's why the blurple won't give good results. They're excellent as supplemental lights to white light, not to be grown under by themselves.

Interesting information Kanzeon, I really appreciate it. I have already thrown in some white light to supplement before picking up a full spectrum sunlike fixture!

I appreciate your opinion PhatNuggz and bluntness. You're right, it is a cheap / average light, however are you telling me that plants don't grow well under mixed spectrum LED light? Because if so, I'd say a lot of growers using non-sunlight imitating LED lights would disagree with you.

I'm saving for a sunlight spectrum LED fixture right nw.

WTF? I directed you to an actual full daylight MIXED SPECTRUM light, so how could you even ask this question?
