Lighting for a 32"x32"x48"

[Olive Drab Green]

You think 3x Vero 29 will cover his space well??

Yeah. I cover a 4x2 area with 3.

Ideal! Think ill purchase tonight

See?

See?

Is there a reason your lights are all individual? Isn't there a driver than can push the three to the limit? Looks great.

What are the ambient room temps? What about the temps under the lights? I see you're not doing any cooling.

I just bought them that way. I bought three Tasty T1s instead of one Tasty T3. For modularity. Ambient temps are room temperature plus maybe 2-5 degrees.


That whole closet is only under 241w of light. 270w altogether with actively cooled heat sinks.

You can get em separate like that so you have more options to move them around.

you can also buy athem all in one too.

Plus it looks like those single lights use more wattage than the 3 in 1's

COBs don't need AC. What are you talking about? And if you are sharing AC with the veg room, you are still paying for AC. You don't need AC for COBs. You are clearly the one who doesn't know what he's talking about.

I save real money by not wasting it.

COB LED needs less cooling per kW than light bulbs but they still need some. In small grows it's much easier to get away with no active cooling for them but as scale increases it still becomes necessary.

I understand. All my COBs are actively air cooled. I just mean there is no way that they will get anywhere near as hot, watt-for-watt as an HID incandescent-type operation.

Agreed.

Having run the experiment, I can definitively say that plants do need some heat as well as light. Balance is key; good quality efficiently designed LED comes much closer to the ideal mix than any light bulb I've ever heard of.

Looks like what's his bucket got his hps light. Otherwise he'd have been happy to show us his plants, lol

Tasty LED

T-22 would be perfect, it is $310 for a kit or $360 assembled.

$200 would get you two COBs and driver, from Tasty, that could run up to 140W and put out more light than one of those 900W LED panels on Amazon.

The T-22 runs four COBs at 45W, I believe.

 

[Enigma]

I forgot to mention, the 5W emitter panels on Amazon that claim 900W are actual draw of about 400W.

Less than half the power with a higher efficacy.

One thing I've learned from other LED grows is the temperature increase, most have noted that an ambient temperature of 80°-85° F will allow better respiration than 75° F.

Lower temperatures were needed for HPS because of the heat, LEDs are more efficient sources of light in that less wattage is waste-heat.

On top of that, 140W of LED will bring my space over 1k PPFD. To do that with HID I'd have to actively air cool or water cool the lamp.

And since higher air temperatures are better, that means even less load on the AC system. Win-win!

 

[Enigma]

Exactly!

I'll still run everything at night though, power costs less at that time. The COBs are passively cooled for now, if I drive them harder I will figure out an enclosure.

Still, the only issue with the temps is drying and curing. I'll have to build a cooling box to keep them under 70° F.
