How much more yield with a good LED 1k vs 600 hps

I have a plant that's a bad yielder, I grow in DWC. I get about 9.5 oz's in a 4x4 tent under a 600 hps. How much more yield would a get with a about avg LED 1k light?

That’s almost impossible to answer, in my experience around 400w of high quality led can replace 600w hps, 1000w of average im guessing will replace 1300w of hps.

I have a true 640 watt LED covering 4’X4’ and it kicks ass. 1000 true watts, depending on type, should cover 7’ square I’m guessing.

For one plant 400 true watts is enough

Well I need it to cover a 4x4 area, any good recommendations on a good light and price, something very good.... Also will this light give off more heat than a 600hps? These 2 plants I'm getting in the 4x4 are bad yielders, I'm getting just above 9 oz's total. Some LED that would give like closer to 12 oz's would be nice.

LED will only lower the electric cost of growing your 9oz. Jusy sayin.
LED isn't a magic yield machine.

Went from 600w HPS (16oz in 4x4) to a 645w gavita LED and got 23 ozs.

Different strains but the buds were much denser.

The amount of light these top LEDs produce is crazy! I come out of the tent and just see green lines for 10 mins lol

I will be doing a comparison journal here very soon just for this reason alone..

I will be comparing 400w led's vs 600w hps, side by side comparisons so we can see what the best option is..

Ive been fortunate enough to have some others interested in this comparison and I cant wait to start it here soon..

9 oz is not a bad # … unless that’s wet weight …. For me it’s not the weight it’s how good the medicine is ….

Going from a 600 hps to a 600 watt LED set at 80%, I'd expect a 50% increase in yield (using less power) for your first grow, but if you dial in all aspects of your environment, media, nutes, feeding schedule, etc, you could potentially yield quite a bit more.

So you need about 480w minimum LED (Samsung 301b efficiency level for example)
Up to 650w , I wouldn't go higher for that space.

So if you want less heat go with less than 600w.

I just pulled about 22oz off one plant in that space. Pulled 37 max before. 560w of QBs

All that's pretty irrelevant but I'm 100% I wouldn't be anywhere near 9oz with even the worse yeilders.

I'd concentrate on your training and canopy management before spending on new lighting.

P.S we are all talking real wattage.
Not some equivalent marketing nonsense

Hmmm ... I would heed the recommendation from the boys of ZZ Top - "... and go get yourself some cheap sunglasses."

Yes! I got some UV glasses cause it was messing with my vision really quickly. Also feels like a get a headache when working under the light for more than 30 mins. So hat as well xD

Maybe some factor 50 sunscreen as well xD

Was that with added co2?

Nah man. Probably could’ve done with it tho as deficiencies started creeping in mid/end of flower. They were autoflowers mind you so could’ve gotten more weight if photoperiods with a longer veg time.

Sszh uses the same light and gets ridiculous yields. His diary is in the grow journal section

Actual watts not comparative wattage
Many times the quoted wattage is false
Don’t believe the output equivalency

You mean a 1000 watt led that only uses a 100 watts isn't the same as a 1000 watt hps? Cracks me up how many people believe what they read when reading what a light company claims.

It’s like an infomercial for cook ware
By now we would all own lifetime pans and knives
