Led lighting

Wondering if my 1500w led grow light is enough for a 4X4X80 grow tent, or should i need two

Light manufacturer should have specs on their website. Also, is your light 1500w or 1500w equivalent? There’s a big difference, not knowing make and model.

Thanks for your comment, i geuss its equivalent, 250w. W250 write on the manufacturers label

You will need to see if the fixture lists the actual power draw.
If it's an older 'blurple' fixture, then a simple metric for HID lighting and older tech blurple diodes would be 50 watts/sq ft of canopy.
That's the amount of power you'll need to achieve adequate light levels.
When you step up to current-tech diodes like the lm301h, you can achieve the same light level @ 30 watts/ sq ft.
So, for your example a 4x4 will need 800 watts of blurple leds or 480 watts of top-tier diodes.

Thanks for a very detailed comment, written on label 250w newest model, plants are 4 Bruce Banner auto feminized (first grow) in 10gal fabric pots, in promix. I almost lost them in my incubator (may have let them to long, 2 or 3 days). So I panicked a bit, all is good now, but I guess the real question is should I buy another light later in the flowering stage, the manufacturer says only that the core coverage form 18" to 24" is only 2.5 feet by 2.5 feet. 24" (750umol/ms )and 18" (812ms)

You'll benefit from extra light in flower. The footprint will expand, but flowering plants also like a higher intensity light.

If I buy Bloom plus 3000w (manufacturer says 600w hps/md) and my 250w cheap 0ne i should be good right for my 4x4 grow tent.
Amazon search:
B082XY8B75 (3000w led)
B075SRHWQP(1000w led)

Well, l apologize, l have finally bought a 1000w hps/mh, but I will keep my led light, could I use a 1500w (250w really)led light to keep a mother alive for cloning, I would like to thank everyone for your help.

[gbauto]

Your 250w fixture should do a 3x3 veg area.

[ChadWestport]

Yep, that light will work fine for clones. Likely can keep it 24" off the canopy top.

Thanks guys, the grow is doing fine at 11 days from germination, I think it's going well

The equivalent rating some manufactures use can be unclear, especially when one realizes the real power rating is the key factor.
