I agree, the price just needs to be more reasonable, and I know its already gotten a whole lot better.
To be fair, if space, temp, and other environmental factors were not an issue, I still may use HPS at higher wattage for the 'bang for your buck'.

That's the reason I went with VERO 29'S instead of the CREE's was the price. I still have my HPS lights if I need them. I do use MH at end of flower. There is a noticeable difference in Electric bill. I can grow more in my space. L00king at a 20% increase in yield. The lights paid for themselves the first run. So bought more and more of the VERO's.

I can run 6 COB's at 1050 ma with a HLG240 2100ma. 2 in parallel x3 in Series or 9 at 700ma. But running at 1050ma is the sweetspot. Doing it this way gives you better coverage plus lower temps which extends the life of the COBs and you get better efficiency. Heat is what destroys the components.

1050 Ma depends on the forward voltage of the cob.a D series or A series will be completely difderent.
I run D series so there only 38 volts.1400 MA is perfect for D series.38 volts multiplied by 1 amp would give you less than the required 40 watts per square foot.would take alot more cobs with 1050.
1050 good for 45 volts and up

@Heisengrow I know you know your stuff, the proof is in the pics of the plants that you post, but you're leaving out bits of information that may leave an LED beginner confused. For instance I run my cree CXB3590's at 1050ma for the extra bump in efficiency, although to do so I have to run them tighter together and more over the same space than I would at 1400ma. In my situation 8 at 37.5watts each is perfect to cover my tiny 6sqft space at 50w/sqft. I don't have the space or headroom to grow the massive plants you do so the lower wattage is perfect for my application. The versatility and scalability are part of what makes LED so great.

I was saying you have to multiply the forward voltage of the cob to the amp draw on the driver.
That means everything.all cobs have different forward voltages so that has to be taken into consideration when choosing the driver.
I run 38 volt cobs and 15 of them over a 4x5.
The 1050 driver would only give me 28 watts a square foot so I needed to run the 1400mA driver.
Saying the 1050 is more efficient is a blanket statement when it all comes down to the cob forward voltage.
28 watts per square foot on a 4x5 is to weak.
The 1.4 amp gives me 39.5 watts per square foot which is perfect IMO.
I have 15 cobs over 20 square feet giving me right at 1 cob a square foot minus the 6 inches of outside diameter

Yes, you are correct. I started out running the COB's this way to get the COB'S closer to even the spread out. About 8' apart. 1400ma is what I normally run at 10 to 12' apart. It's a win win which ever way you run them. Also I have accumulated more COB's than I need,so I put them to work this way.

Thought about ordering some 2100 drivers and light them up lol to grow 8 foot plants in 13 gallon buckets.would be bright as fawk

Nickel is a micronutrient that the seeded plant should have in proper amounts for strong seeds.Alot of breeders miss that important micro or change something up in there solutions.Could be a possibility.

Yup when you are producing seeds your nutrient regiment should change. You definitely want way more micros and veg through 'flowering'. Micros micros micros.

Just my 2 cents but for $25 more you can have the latest Samsung LM301B and support a US based company and family that does their best to keep as much production and assembly as possible in the USA. I am one of the early adopters of QBs and thankful for HLG for proving the naysayser wrong with these lights. I stick behind them and their product and so do they.

Thise are nice too. I love my lm561c s6's but I like those too. I believe they are just a bit more efficient than the 561s aren't they

Lol I'm over 100w/sqft if I crank em up. But I do run more than needed. But they do dense up the bottom nugs even with some canopy in the way. I usually try to stay at around 85w/sqft. I needed it for the LVTK. I pulled it out. Had a really good look at it. It is super lanky og structure. I may put her back in flower.

I have a keeper LVTK. Frostiest bud so far.

There are some amazing phenos in that line I have seen. Some people are getting duds though every now again with not much vigor and buds are bit stringy. Not a big deal imo at all but it does seem to be popping up.

That's why I pulled her. Bc the bud sites are very stringy.not even sure they would make gold ball size. I cant remember what day it's on. But they should be slot bigger by now. They are about the size of your ring finger fingernail.

I've got one for you...I had some plants going late last year, outdoors. I was working on moving them from Solo cups to 2 gallon nursery pots. As I'd translant, I'd set the 2 gallon pot on the ground. I'd just set my third or fourth plant down, and no sooner had I turned my back than a chicken came up and started stripping leaves off, starting with the top, of course. Chickens love marijuana plants.

I have stoner bushy tailed wood rats, once many moons ago when I did large gorilla grows I hiked in to find over twenty plants totally gone at first all kinds of thoughts went thru my mind but looking close seen the plant stumps looked like a beaver had chewed them, looking around it had stored them under a fallen tree all neat like, then in my yard couple days ago it happened again only more devistating two of my four girls fallen like cord wood... SOBs
