Giving her a few more days and if she doesn’t show me something she will I’ll be laid to rest and I will start a new seed.

A little worried about the moonstone

man, Citrus Noir!, mine this season was xtraVig!
This one looks strong. I transplanted the moonstone to a smaller pot and dropped a whit widow in the autopot.

good move, kept the auto pots full of real happy ones
That was my thought. We will see if she makes it or not.
Nice lights. They don't look like small cobs. I wasn't able to take a good look. But they look like LEDs on a PCB board with added lenses.
A LOT of these are popping out, mostly claims to follow Fluence spectrum exactly. They are very easily customized for any spce due to bar design. Uses Lumileds or Osram so the diodes itself are not expensive. Its the frame/heatsink and driver that pushes up cost. Efficiency is close to all high end LEDs so its a good choice.
Of course, I'd love to be able to see all the specs, as a lot of the above are just my best guess. They will grow some mighty plants! My only issue is with the China made driver, which is probably nowhere close to the capabilities of a Meanwell that is made in Taiwan.

They are full spectrum white light - for autoflowers we have found using 4000K gives the right amounts of blue and red to go from seed to flower (thanks to tests done by growers on Autoflower.net!). PPFD on this set up will run around 800 across the canopy, no hot spots - but depends on height above canopy. When the plants get into full bloom I would keep the lights as close as 6" above canopy for max PPFD but then raise the last week of finishing (or use a dimmer on PSU).

The lights actually use Samsung mid power LEDs that have the highest tested luminous flux in the LED industry. They test out in "lumens" at 223 per watt. No heat sink is needed as the LEDs are driven at approx 80% of max instead of over driven like many. Fluence "spectrum" is not really anything - white LEDs typically come in Kelvin ranges and 4000K is best for full cycle growth. Fluence adds in a few 660 Reds but honestly it is more marketing than anything.
The PSU is Inventronics which is stocked in Tulsa OK and made in China - comes with 7 year limited warranty
The lens you see is actually a clear acrylic that is there to protect the LEDs from dust / spray. It costs more than conformal coating (which is like a silicon covering) - but it won't bubble or crack.
The light channels you see are called GroBar X. There are multiple versions that can be driven up to 120 W per channel and you will see different wattage fixtures coming out soon. The GroMax was designed for 2' X 4' areas particularly for home growers. It will put out PPFD higher than 400 W HPS easily. Two of them outperform a 630 W CMH easily and actually more than 600 W input LEDs
The commercially available fixture ships with a 9 foot whip so you can put the power supply outside the tent for added heat reduction. Power supplies, like bulbs, retain heat and create hot spots.That said, it is important to realize that a watt creates 3.41 BTU - heat. Dissipation of heat over a larger surface area reduces hot spots, but there is still 240 W running through the LEDs creating heat.
