$400 to light a 4x4

[Olive Drab Green]

My point was what you actually said was wrong I'm not sure what you meant but what you actually said was wrong you spent 2 pages saying what you said was right it never was. what you meant to say may be right but that doesn't matter all that matters is what you actually said which was completely wrong.

Besides, the information I was going off of was prior to the V2. I apologize.

Again, you totally missed my point and are now wrestling with your own projections. Scroll back and see where this started. My argument was not about the strips, that was just one passing comment in this conversation.

You said the V2 if you said v1 I would have agreed with you....but thank you for admitting you were wrong.

I suggest you look to buy “samsung quantum” copy boards from china for 400$usd you can get 4 boards with heatsink, shipping and drivers for a total of 520w and will blow out any 600hps light.. best bang for your buck if you dont want to diy with strips or spend more than your budget. Will cover well your 4x4 space. May be a bit less efficient than the top bin real quantum boards but still represent to this date one of the best buy money wise..

Great suggestion but shipping is the real deal

Your mistake is that you think I am afraid of being wrong. I’m not as egotistical as you think, that is merely a projection of your own ego. I did initially mean the V1. I had forgotten the technology had recently been upgraded with the V2. I was confused, and I apologized.

I've been utilizing only 1/4 of my tent space (2 plants) because I currently have a "2,000 watt" LED. I'm committed to spending around $400 to upgrade my lighting with hopes of also lowering my electricity bill. What's the best bang for my buck for my price point?

Welcome to led section where no one cares about op question and they go mad everytime a troll jump in.
I'm Sorry

I don't see the point to the massive efficiency shootout if you limit yourself to a hard budget of $400.
I'd just buy whatever put down the most photons for my money. At the end of the day most small growers can only afford to light a small area, so gram/square meter becomes a more important metric than uM/W

True... Just found this.. https://newyork.craigslist.org/brx/grd/d/hydrofarm-hps-430w-grow-light/6704335192.html

That's a much bigger step in the right direction.

The COBS many have posted are nice, but they're just way too expensive to justify the cost compared to how cheap you can get MH/HPS lighting for.

And unless you live in Hawaii, the power savings isn't worth it either.

Wire and waygos and you're off.

 

[Dear ol" Thankful Grower!]

I’m still thinking 2 closet case 100 or optic 2. Problem with the optic 2 is only covering 2x3 space in flower figured two closet cases at 400$ would cover more room https://spectrumkingled.com/collections/grow-lights/products/closet-case-100w https://opticledgrowlights.com/collections/full-cycle-growing/products/optic-2-210watt-led-grow-light

also a single 400 in your house is pretty easy to cool

Efficiency is only interesting calulated on fixture level so incl. driver loss.
You can built a fixture more efficient like quantumboards; also when using F-strips. In the end it depends on how hard you drive them and what you are willing to pay. 5pcs double row 4footers on an HLG-240H-48 would be <60mA per diode and would beat a normal 260 v2 kit easily efficiency wise but thats not a fair comparision(1440 LM561c vs 576 LM301b).
The only thing where strips are unbeatable is the light loss.
One can use them directly above and/or around the plants with only 4-8" distance from canopy. This reduces the light loss on the walls 4 times compared to 16-24" distance.

Why doesnt anyone ever recommend running cobs at their higher ratings? Efficiency doesnt suffer too much, initial expense is driven way down. Aside from having to wire and power fans, the build isnt any more difficult.

Great suggestion but shipping is the real deal

4 boards = 25$ x 4 = 100$
2 double heatsink = 20$ x 2 = 40$
2 drivers = 2 x 70$ = 140$
So about 280$ + 120$ shipping delivered in 2 days from China (declared value of 60$ to lower custom fee) brings the total cost to 400$ usd.. my last purchase was less than a year ago I dont think prices have increase by much if they did..

Its not a bad idea but you have chances to create massive hotspot you probably need higher height too and im personally scared by many reading about active cooling cob if the cheap fan break your cob fry and maybe everything else.. i think there may just be better option out there at a reasonable cost rather than cranking up your cob to their limit.. might as well stick to hps at that point but just a thought

That cheap fan is considered effective for a extremely expensive cpu/gpu. Burnt out cob can be replaced for around 50 dollars.
I do see your point about height but even run hard a cob will be more efficient than an hps.

 

[CobKits]

Burnt out cob can be replaced for around 50 dollars.

Not many people spending $50 on cobs these days. $10-$25 is a better estimate

true. Think i spent around 30 for my cree cmt 2890's

Your plants look impressive.
Maybe when someone grows a plant that stretches for 7 weeks during flower and takes 14 to 16 weeks they will have a greater appreciation for how difficult it is.
I'm inspired by your long flowering sativa grow.

I didn't realize you were doing it with LED, all the more impressive. ​

I run them hot, personally.

I appreciate it, bro. Thank you. That was kind of my point earlier. The genetics under those lights are pure Sativa.

(Kerala India x Purple Highland Colombian x Thai x Mexican). The female is that, plus Malawi landrace. With that in mind, they sure as fuck aren’t spindly. It isn’t crossed with any indica, so of course it doesn’t look like a squat little hybrid.
