3x3 tent

4 panel QB and COBs ( 3500k all )
Power currently : Dimmed to 355w
( next week " Step on the Gas " ) ....... Lol

Mephisto TOOF Decay
HSO Blue Dream ( s1 seed )

From the selfing of a BD that got some CS on branches and then self pollinated a branch for fem seeds. Ended up with about 13 dark mottled seeds and a few under developed.
This S1 is the first from that bakers dozen of S1 seeds. Pheno is much different , more slender branching but smells the same , sweet / fruity.

It did retain the auto trait and began flowering on her own , but stretched a bit more than I needed ..... So I supercropped the main cola a few weeks back. Simple pinch and fold and no problem. She is in mid week 4 and is budding up nice.

MEPHISTO TOOF : Week 4

Well she is powering thru with some fading but she has tons of leaves left.
I did up her feeding a bit with a dash of nitro ... ( scratched in to top soil )
But not really too concerned as she uses the leaf completely before they fall.
Anyways she has a deep spicy earth smell at the moment . Figure this will at least go another 4 weeks minimum or so.

I have been running the G8 with these two plants daily but forgot to hang it today , late for work.

Hey guys so got another question here.
Feeling pretty dumb already...
So I ordered my dad a couple HLG qb288 slate 2 double scratch and dent sale.
I got an hlg 480h c2100a to power all 4 of em.
I wired em in series like HLG site says.
So hooked it all up plugged it in and the lights came on but very dim...

Not sure why. I thought the math was right.
Each qb288's are 53.28v @ 2100mA. That's 213.12 V @ 2100mA with all 4 n series right?
The driver is rated from 114v to 229v so 213.12 should be good right?

So why is it so dim? I tried adjusting the screw but it didn't change the brightness of the lights.
What am I missing or what did I do wrong?

Did you wire in series or parallel?

Sorry I seen you said series.

Take a picture of the wiring

Can't take any pics now. The boards are at my dads. But here's a poorly drawn picture lol.
That’s a bummer man. Looks wired right. Are you sure you were able to adjust internal pot? You need a small phillips screw driver and sometimes you might think your on the head of the pot but your not.

Yeah made sure the screw driver was seated well and turned till stop in both directions.
Unless the driver is under powered some how...?

Thank you. I'll attempt it... Lol
Best way to go at this is if you have a meter with very sharp lead tips you can pierce the wire jackets - go across each board from the positive wire to the negative wire and see which board has more voltage across it. That's where the problem connection will be. If all the boards have the same voltage then its probably a bad driver.

Thank you very much. I will try it tomorrow and report findings lol.

I got the 6'x8'x8' for $149. I'm replacing it this year with a 10x'10x8' .The 10x10 can be had for $259 shipped from ebay.
Last year was a shit year, couldn't plant till June 7th and still had an outstanding crop! took a kilo from that little one
What does something like that cost?

I think you have a bad connection somewhere in your loop that's causing high resistance. You need to meter it out and find out where the voltage is dropping.
I had a similar issue over the weekend, i had one wire not long enough in one of the wagos, (medicated before wiring bad idea) drove me crazy, I finally went to the shop got multimeter and found the issue.....

How would a DIY HLG-600 Kit compare to a 1150w DE HPS? i have been contemplating replacing my 12x 1kw DE lights with these affordable LED's but i dont want to sacrifice nug density, yield and quality to lower my electric bills. each HLG600 will be per 5x5 canopy space. this will be about 25w per sq ft. right now they get about 46w per sq foot of DE HPS light
