Which is more beneficial, a 300w LED lamp (red/blue) or a 1000 w HPS? As currently I have a 150 w and might upgrade soon

Im assuming this is a honest question. 1000w hps will blow a 120w led away by a long shot. Theres nothing to compare between the two

yeah, your talking like 2 completely different grow rooms. That led for like a footlocker, or the 1ker for a 5x5 room...

I meant 300w led lamp,my apologies. And I believe you might be wrong as an led lamp features spectrums of the lights that causes the cannabis to flower at an early start and produce a high quantity as red/blue (has orange too by the way) is what they want most

1kw hps will out yield a 300w led too id say. Do a little research there buddy, did you plan on pulling a pound from a 120w led? I havnt read any journals of people pulling a lb under 300w led let alone a 120w and I read alot.

Way too many variables.

What is the grow size?

What are your ambient temps?

Can you get an aircooled hood and larger exhaust if needed?

I'm running a 240w listed LED light in a tiny cab, less than 6 square feet and only like 3 ft tall. The 400w hps fried that little cab

whats your average yield with the 240w led

if anything you should get a few smaller ones instead of one big one if choosing led.

you get better light dispersion. if you had a 4x4 instead of running 1 300w led you should run 3-4 90-120 watt leds

Sadly I have not got to put it to real good use. I had one run that was completely LED. Sadly many of those posts got lost when RIU had major issues earlier in the year and lost tons of posts it seems. I just went through my thread looking for the numbers I had. I had 4 plants, two romulan and two blueberry. The BB stretched into the light and burned the tops, so I bent the stems and they grew into the light a second time. Sigh.

From my thread one bb plant had 12g dry, I think the second one was a little less but better pheno. I'm not sure what I got on the roms. Lets say 4 plants 10g +/- 2g so anywhere from 32g to 48g. I had used those paper cartons that soy milk comes in as containers in coco and used the Lucas formula. The cab is 28inx17in and 30 in tall.
