DIY with Quantum Boards

Got a great deal on a 2 board quantum board with LM301h diodes, from a local seller who built it but couldn't use it. Excited to push these ladies hard, might need to lift it higher
*might*, don’t know how hard the board is being pushed, but all my kits can’t get closer than 22”.

Im probably not doing something right.

Grats on the new light!

Thank you! I decided i should go check on the ladies before lights out and there were a couple lightly burnt leaf tips, and early signs of bleaching so I raised the lights a couple inches, I think it might be good to a little higher yet, will check them out when they wake up

KKP ( Durban Poison x GG4 photo ) :bigjoint:

Well the 3 Soil grow bags outgrown the 3x3 so had to shuffle things around. Kids STILL didn’t come for their shit left in room so had to improvise…..

2 went to that area ( after the Ethos and master kush came down - now drying ) under QB225 and Supplemental lamp. They bushed out pretty damn good for a single gallon grow bag.

The largest one stayed in the 3x3 alone under the QB 304 / COB rig.

They will get their final pruning this weekend and LST retightened. All were flipped 3 days ago.

Medium :

EB Stone Recipe 420 soil
EWC
Perlite / Pumice
Dry Fert ( Recipe 420 Recharge Mix 6-8-4 )
( using thru week 2 of flower after stretch ) then
Recipe 420 Ultra Bloom 2-8-8
Tap Water with Kelp
1 gallon grow bags

Droop from watering a few minutes ago. :D

Hey y’all I need some assistance. I have the HLG 288 V2 dual quantum board, it pulls 273watts from the wall at it’s highest notch, and 173w out of the wall at it’s lowest . In veg I usually have it 18-20 inches from tops and at 30-40k Lumens. Temps are around 81, humidity 50-60. My last grow was in a 12gal SIP, in coot’s mix, it seemed like it burned through all the nutrients. Anyways my tops started to get real crispy almost burning them at around week 8. I started getting fox tails around 7 or 8 weeks and my final product has a grass smell to it. I would say in late flowering the closest top was at 55k lumens, maybe 16-18” away.They are good genetics: SFV OG x Stardawg from Greenpoint. I kept the humidity down to the 39’s.

I grow in a 3x3x72” tent, 4” hurricane in-line blowing the air out of the tent through a filter.

It just seems like this light is too intense. I had a clone in there at least 24-30” and my leaves were constantly droopy regardless of the soil moisture. Even when I took it out and put it under my bathroom lights the leaves come up.

How far away from the tops do you have your light at? What is your ambient temps? Do you raise your lights towards the last few weeks?

i’m stumped

Pics of damaged tops.
I run mine 18” - 20” from canopy ( dim controlled ) i look for lateral leaf spread to dictate . Plants can often run differently under led at times - some become calmag or feed hogs.

I never tun balls to the wall with my gear - best to have more pedal than lack of it.

Also … not to be a debbie downer - take Greenpoint offerings with a grain of salt. Ran many “ stardawg “ crosses from them and was mostly meh. They used to run seed auctions and was suckered before. The Deputy was a good one.

Yeah it’s definitely my last run with them. Do you have anyone you recommend?

I wasn’t seeing any cal-mag deficiencies, I thought about adding more, but with the amount of good homemade worm castings and the fish bone meal I figured it’d be enough. I do believe I could have gave her more nutrients there at the end.

what are your preferred temps? It seems when it’s lower than 75 they don’t grow as well, 81 seems to be fine. Do you keep those temps well into harvest?

For me , I try to keep plants around 80° + ( cali ) …. Growth can slow with lower temps sometimes.
I don’t use cal mag much at all because of it being in tap water / nutrients. EWC / Kelp are always added to my soil mixes.
‘Silica foliar during veg stages ( twice a week ) ….. that’s pretty much it.

No particular breeder - but green point has had some drama when it was discovered strain “ pics “ where grabbed / colorized ( beautified ) from other sources - claiming that was what strain would look like. Many decent breeders out there.

Mosca
Dutch Passion
Cannarado
Hazeman
Etc.

Well the tops didn’t get burned just crispy. A lot of trichomes looked like they were degrading. I think next time I’ll make sure the plant is small enough

There be some chunky nugs there. Good to know plants are working thru it. High intensity light can stress a plant thats why i dont mash the gas too much plus it keeps the gear lasting long term.

A few points of clarity and honesty for our community…

HLG and GML in 2021
Thomas Gibson (GML) demanded 10% ownership of HLG, Steve and I were not comfortable with that. At about the same time, we became aware that GML sent samples of HLG lamps to China to have them reverse engineered so that he could develop his own brand. This created a situation where continuing our relationship with GML being our Canadian distributor was no longer possible. We wish Thomas the best in his pursuit of developing his own brand.


Is HLG being sold?
The short answer is NO.
Steve and I love what we have built at HLG and we are excited about new products that are currently being developed.
We are one of the last remaining North American manufacturers of LED lamps for horticulture, so we get approached regularly by different types of investors.
There is no way to predict the future, but currently there are no plans to sell any portion of HLG. Steve and I stand committed to continuing to build our brand and pushing LED technology forward for the entire horticulture community.
We invite any of our customers and supporters to visit us at our manufacturing facility in Tennessee at any time. We love to share with everyone what we do and how we do it.


Is 3.2 mmol/joule real?
Yes. Independent tests confirm that HLG lamps have been tested and certified at this efficiency.

That said, there are variables involved in testing (test methods, testing equipment, driver performance. LED tolerances as per manufacturer, etc…), so there will always be some variation in product performance, but independent 3rd party testing is the best way to compare products from different manufacturers.

HLG has never and will never produce a lamp for test purposes only. All lamps sent by HLG for testing and certification are produced 100% with our standard components with our standard processes. Any contrary suggestion is malicious and slanderous.
We will not participate in juvenile mud slinging, but we will defend our brand.

Do any manufacturers use only the highest flux bin LEDs available?
YES! HLG uses only the highest available flux bins on our QB 288 and QB 648 modules.
Even smaller lamps like HLG 100 and HLG 65 are transitioning to highest available flux bins and we do not plan to stock anything other than highest flux bins.


HLG USA Production
100% of these models have been produced by HLG in Tennessee:
HLG 65
HLG 100
HLG 225
HLG 300
HLG 350R
HLG 550
HLG 600
HLG 650R
Scorpion RSpec
Scorpion Diablo


HLG was born here in RIU and we still value your support. :)
Please feel free to let us know if you have questions, concerns or feedback.

Sincerely,
Amit

Ethos Endgame R2 ( pulled a few weeks back ) …
Loud nose smell - gassy fruit
Crimson reds and purples

Haven’t really had much to say about this one as it seems to lag a little compared to my KKP that are twice the size in same time period. This plant is very sensitive to handling - fans easily break off.:cry: But so far i am just watching her i was going to continue training but decided to keep her going a couple more weeks then just flip it. She has been responding to the silica foliar well so far.
