Hey buddy. I'm struggling a bit this time round. Trying to match umol figures in books, that are beyond my expectations. Your grow looks good. Have you been around it with any sort of light meter? I'm at about 1600w of QB over your space, but somewhat closer to the plants. My feed demands are astronomical, so I simply can't run 2500w as you are, but have 2850 installed (If I could use it all)

Thanks for the compliment,no I haven’t taken any light measurements yet,l think I have a fairly even conopy,I’m using 25+ gallons per day in water and some plants are drying out within hrs in a 3 gallon air pot..

How hot do your drivers get? If i dont have a small fan on mine they get so hot that I can barely touch them. And some of the connectors that I use to extend the DC power cable get real hot to the touch too. Just want to see if you have similar experience.

To tell you the truth,I’ve never touched the driver or the heat sink,I don’t even look up as I value my eyesight...lol,I do have a couple of inline fans blowing across the top of the lights...my room never goes above 82 in the cooler months,in the dead of winter mid/high 70s is normal in the room...

Thats all normal.. the hlg drivers can run up around 50-70 C or higher.. usually too hot to touch.

That doesn't seem right. Make sure the cords are properly seated in the connectors and check that you are within the connector ratings.

connectors should have the same temperature as the wires. If they're hotter it means a bad connection which could get worse and even start a fire.
Careful when checking turn the lights off to prevent any chance of shock.

That is a bad ass garden knuckles. I would grow flat if I could do it like you do. All my flat LED plants droop like they dont dig the light. Vert though,Yeah Baby!

Thats what i was worried about. I guess I’ll break everything down and double check them.

Fantastic thread, thanks for sharing!

Very nice knuckles. Are you running those at full power and those buds look about a foot away from the lights in the picture. How close are they ?

knuckles · Jan 9, 2020

Thanks guys!yes I’m running them full on...and yes some tops are 12inches or closer,I’m very limited in height (6:7) total..

Hi knuckles , thanks for sharing this beautiful grow

Can you please tell me, after all this time running the HLGs, how you compare them with your old 6x600w hps light setup?

Take care

Sorry for the late response (under the weather). First thing is the heat has been cut by 40%, which is huge bonus
Also I can get the plants much closer to the fixtures,and the light canopy is way more evenly spread out over my 4 x16 area..I am getting a better product as well,and have found my plants finishing quicker too..I do have have far red coming on after the 12/12 cycle ends for 10 minutes.

Oliver Pantsoff · Jan 24, 2020

Yeah, I notice my 9 week strains finishing like 7-10 days earlier under my hlg550v2's...Been running hps for almost 20 years, so it was a shocker for me. The quality n yield is up to par also. I'm ditching all of my hps now!!
