Hey! Here's a good laugh for you all. In a really piss poor article on High Times on LED lighting, I found this gem of ignorance, among all the others..........

"PK: LEDs are not subject to the “Inverse Square Law,”

here's another gem:
"White LED have huge amounts of lumens and much lower PPFD, as they are designed for the human eye curve (generally too low on red 660nm to have the best blooms) and our visual comfort, as compared to mono LED which are used for plant growth that target the exact wavelengths of light the plants need and produce higher PPFD but lower lumens."

Well they know they need to push the narrative of the big advertisers...... Kind/Cirrus......

7 days since i saw the first white hairs.
growing in 60% perlite, 20%coco, 20% promix, in a 10 gallon tote, set up like a hempy bucket.
feeding every other day, just Jack's 10-30-20 blossom booster, with a light top feeding of sul-po-mag,which makes it 10-30-40, as close as i can figure, just a light dusting, and let it get watered in
just did a light "defoliation", to improve penetration and ventilation, was almost a solid cube

90 CRI

QB 480 is a test board with 480 Diodes. Currently still under prototype. exact same dimensions as qb288 and qb304 for now.
We are testing and optimizing design for voltage, cost, efficiency. needs to be sphere tested. Should be most expensive board yet due to highest diode count.
Currently production is not scheduled so it will be a while before this is available for sale. No pic is available

QB 288 90 CRI is a test board with 288 Diodes. Currently still under prototype. exact same dimensions and diode count as QB288
We are testing and optimizing design for voltage, cost, efficiency. Needs to be sphere tested. Production will be scheduled next month and this may be launched July or sooner

Standard QB288 and QB304 Production to continue. Batch from mid next month will have twice the copper for even better thermal & electrical conductivity

June mid, Slate 2 to come in single double and triple.
June mid, Slate 3 Blue to come in single and triple. replaces slate 1
June mid, Slate 4 to come in quad. 600x600mm plate for 4 boards. upto HLG-480, compatible with Slate 2 to support highest thermal management
June mid, Slate 5 to come in quad. Extruded for 4 boards. supports highest thermal management
June mid, optional reflectors compatible with QB 304 and QB288, 1 pcs goes on long side of each board. uses same 3 screws along long side board

I'm already jealous of the upcoming boards, but this is how tech works!
MW 100-54 works from 31.5w - 107w if i'm not mistaken. System level propably. I'll leave it to 50v and just play with the amps.

Can someone draw a simple 3 board series wiring. I've seen the hlg board guide but i get confused with the parallel series wiring.

Update week 9 - 3 panel QB Batwing

Power level adjusted 205@ wall - 320 max

These GSG girls are in the home stretch ( final week ) ... The Batwing build has proven itself with nice tight chunky goodness. The operating temps are ridiculously low and never had that " Open Oven Door " feeling . The last week while i was out of town , i left tents closed while gone ( somebody would check on dog while gone ) to see if " i had to open tents " BUT ...... They ran flawlessly zipped up and temps maxed at 81°.


Anyways , they are right at the snowy trich level i like. No need to wait for amber.
I gave them HYDROPLEX and water ( 6.5 ) today and will chop probably Wed.

This is there last photo before chop, uniform fade is evident and much more bud flop.

The other two GSG ( clones ) i have going in other tent will be in week 6 and will post about those later.

I want to be put on the list for at least 2 of the qb 480 and 4 of them would be my first option :)
That is all,carry on
