**ULTIMATE LED TEST** *GLH Spectra 290* VS *Blackstar 500* VS *Hydro Grow LED 336X*
- Thread starter WeJuana
- Start date
I am honestly not too sure what tent is producing the most at this point. My deducing a favorite will all come down to the quantity and quality of the smoke to determine that. 2-3 more weeks and we should have definitive answers.

One question I have yet to see answered is this,
What is the ACTUAL difference between an HPS grown plant and an LED? I have never seen test results that prove LED produces a better bud, I have asked Advanced..they hung up on me, I called the people at Stealth Grow.. They said they can not determine an answer, when I asked them why they brand there leds as producing better bud they said that to them it looks better, to which I said looks are not everything, to which the guy on the phone said and I quote "maybe not to you, but to most people looks equal top quality"
So has anyone ever tested there bud side by side with HID grown bud to prove up that LED is better??

@backwood - I have never myself grown the same genetics side by side under LED and HPS, but that is what the next round holds, so I hope here in about 8 weeks we will have the answer of the differences between the two lighting systems.
@PSUAGRO - Which link is not working (which post #)? Thank you much lad and glad to see your presence back on the thread.

Grapefruit grown under HIDs (2x400W HPS) with 100W LED supplemental light + 125W reptile lamp (the plant was getting roughly 1/3 of all lights)
Here is a clone from that same plant, now grown under 135W LED (blackstar 240). I got almost 3 oz from the HID one, PREMIUM taste, I am curious to see if this one can even taste better, I am hoping to get 1 1/2 oz from it but it would have to grow some more, ... looks like an oz right now.
so if you do the math, 1.5 oz for 135watt or 3oz for 350W ...(just approximate numbers...) it looks like my gram per watt ratio will be better with the LEDs... and if it taste better as well, that would be the difference between LED and HID... lots of room for improvement in both setups but this is just my take on it

I only harvested 2 small plant flowered under LEDs so far... the plants had a really tough life and I fucked up big time. 1 of the 2 plants was not nearly ready, the other one was really dense potent tasty buds... only got 1/2oz though... the Grapefruit right now seem to have really nice buds, not fluffy at all, very tight

I must be smoking crack ex coz u lost me when you said 3 ozs for 350w. I read 2x 400w 100w and125? What do you mean third of light

there was 3 plants in the room... I mean the whole plant was not getting all of the light. I had a big hole in my screen with light but no plant and some of the light was being wasted on shitty clones as well so the plant was not getting the whole 1000W to itself capitch?I got 9 oz total from the 3 plants and I know it's nothing special but it was my first successful grow and its A1 quality.
And I am only saying what I am seeing in my gardens at the moment.. it seems like I will get more buds per watt in my LED cabinet than in my HID room. I am unsure yet...

Id be happy with 9 oz as long as you get more than you paid for electricity then its all good
i think an led light makes a scrog look even prettier
do we know that uv really helps? i think thats what you meant with reptile lamp. i havent researched much but some people are saying its snake oil

Anybody know why the blackstar lights (500)labeled "cree" are sold for $740 at growsmart http://www.growsmarthydroponics.com/500w-Blackstar-Ultra-Violet-LED-Grow-Light-Cree-3-watt-LEDs-_p_9092.html,
yet all the other 500 models that aren't labeled cree are sold for $549?
Seems way to high to be the same light with a markup...

heres his new thread , he seems to be acting pretty shaddy not telling anyone his light ratio among other things .... most if not all companies will give you that kind of info ..... i guess if what he says is true we will all see .... lol

It might be cheep to run but if one plants space yields 1.5 oz in 3 months and another yeilds 3oz in the same time in the same size of space then which is better? you might save some money in electricity each month but it will take twice as many months for the LED to catch up with the HID, just what i have observed reading up on LED grows, so like I have said before GPW is only one part of the equation you also have to look at your Yeild per foot, most LED plants barley hit half of the Gram per Meter squared formats. Note trying to start shit, just trying to get the whole facts.

dying to see those final numbers and maybe a shot of your girls naked so we can see total bud growth all over
