Are LED's practical for a grow room? (24 ft x 12 ft)

[Darth Vapour]

Yea, total yield, check. 47 g/sqft here.

Photons are photons. Nothing magic about bulbs. Desired photon density can be reached with either and LED can do it with less watts. Not a lot to debate about those facts.

And this whole concept of one being better outside effeciency, not a matter of yield. You do realise there's upper limits to what a light can do? As I said, both led and hps can be set up to kill a plant with intensity... LED can do it with less watts, that's all.

But hey, maybe DE bulbs have magic in them

But the numbers are not staking up to real time grows with LED / Cob of course you will see on the tube some nice LED grows remember lets put this into perspective most of the times them ones are sponsered by the LED company so there going to make it look outstanding and remember its the internet ,,, whats to say when he was not taping vid ,chances he ran some HPS in there to bump it up lol truth , like you say magician
we just hae to look matter of fact i am going right now into LED forum and will pull pictures from fellow growers and compare them to HPS grown plants REAL TIME

 

[Darth Vapour]

You have been setup for the kill dumb ass. I've grown 20lbs in 1 run before my accident and quitting the dispensary. When I hit my head it knocked some sense into me. Your weak shit is shit and now it's time to show everyone how fucking stupid you are with your own help and keep posting stupid shit please. I need your help

omg yeah from living in your condo right nit wit

I can understand wanting results, especially considering led track record.

But refusing to look at the math, or believing everything is known based on past experience is dumb.

I've provided my data. 1.35 gpw growing bushes is pretty bad ass imo. I'll be trying mini hemp buckets next, 23 1 gallon containers in a 4x4. I suspect I will hit 1.5 gpw my first try, and that will be with year old V18s running at 1.05 amps.

 

[Darth Vapour]

hey real styles here is a idea seriously go into your garden of coblins and pull out a couple take some seperate pictures of the plants show us the MAGIC of what them COBS are capable of ,, I DARE YOU
PS : make sure you take some pictures of them 8 - 9 week stalks lol

Rahz your limiting your self with 1 gallon buckets bump it up to 3 gallon and half the plant count can guarntee you better yields then from 23 1 gallon plants..
I have done multiple rooms 5 gallon 76 plants rooms SOG problem is your really only harvesting top portions of it meaning less yield 1/4 to half the plant if your lucky ,, down size and up size pots is the key for any grow

 

[Rahz]

Well, I've given you my personal experience, that's all I gotta do.

But consider what if... some 1000w bulbs put out 50 lpw, some 70 lpw, some 100 lpw, etc. there would be much confusion. That's the history of led.

Now there are companies producing 130-135 lpw emitters. A person just needs to educate themselves and buy the right gear. Nothing magic about it.

3-4 years from now we'll likely see 140, 150 lpw at test current, maybe more. It's just a matter of time til bulbs hit the dust bin.

Remember lumens are for humans not plants

 

[Positivity]

Hows about upside down?

About a pound from 3 plants...plant on left is split into two for drying grown in a 2 x 4 using 400w. I was pretty happy with the harvest, more so than with hps. Light cost about $850 to build and has quite a few grows under her belt with no end in sight..

actually have to turn her down because she produces too much...

But..I guess this is supposed to suck right?

One of my favorite shots. Leds finally produce heavy plants..



Should be building something...much more productive than
playing whos light is better

 

[Rahz]

Yea, it's just an easy way to talk about it. As lumens goes up for a given area so does par, umole, PPFD.

Getting the price lower on existing models would speed along market adaptation better than developing higher efficiency models. It's hard to choke down $50 for a CXB3590 when 600w hps bulbs are $25 each.

A good 600w hps bulb is about 100$ I don't know where you buy those 25$ bulbs but for a good eballast compatible bulb they aren't cheap. I use the hortilux ones they are more expensive but they are better spectrum wise.

Agreed, but those two things go hand in hand. Drivers and aluminum aren't going to drop much though so efficiency is needed to create substantial cost reductions per watt.

Ebay, amazon, never said they were the best, but they will get the job done.

It is estimated that five million LED light bulbs were sold in the UK in the past year. Which? researcher Matt Clear said: ‘LED light bulbs have a tendency to make grand claims about their lifespan – it’s common to see manufacturers promise bulbs will last 25,000 or even 50,000 hours. But we’ve found many failing well before this.

‘One of the attractions of LED light bulbs is that they’re supposed to last a long time. So if you’re shelling out for these bulbs – typically more expensive than other types of light bulb – you’ll want to be sure that they’ll live up to those claims.’

LEDs create light by passing electricity through a semiconductor. They can fail if they are made from poor quality materials, and are also more prone to burn-out from power surges.

They are also liable to fail due to over-heating if the heat from the light emitting diodes is not dissipated efficiently. Brighter LED bulbs with a greater lumen power are particularly prone to this problem.

Pretty sure those are not eballast compatible they are for street lights not growing weed maybe you should know a thing or two about the technology before you speak about it.

The problem isn't really the price of the heatsink. Most of the time it's the price of the emitters themselves that far outstrip the price of the rest of the components.

Pretty sure those are not eballast compatible they are for street lights not growing weed maybe you should know a thing or two about the technology before you speak about it.

Considering they're typically packaged with electronic ballasts I'm pretty sure they function just fine.... Even if they weren't, magnetic ballasts will still get the job done....

they can and do work but nicer bulbs are obviously better

let's see you talk about something relevant to our lights and not whatever vids you can pull off youtube

 

[Darth Vapour]

you see how nicer buds are better ???? what do you consider nicer buds ???? LED grown lol CFL grown, T5 grown ??? you want something relevant ok
everyone is talking Cree and then on other hand calling Chinese made led's JUNK haha..
When in fact CREE is made in china , Taiwan, Indonesia people are talking about running there Diy LEd's @ 700 mah when in fact its takes different wattages or MAh to create a specific spectrum of wave length cold this be a double standard ???
i mean really
Your mentioning now for some reason LED produces better buds ??? like saying organics is better then chemical grown ??? again talking real time science and studies done proves that is not the case again double standard

could this be the reason Real styles PLANTS ARE STRETHED TO FUCK

PS still waiting for them single plant shots there RS

 

[a mongo frog]

Im actually totally impressed with the diy leds. I used to be a sceptic, however I'm impressed. I just really want to see an og run with them. Same with the double ended lamps also. Sure we all can get great yields doing Dreams or other high yielding strain. So far with the double ended bulb I've only seen 1 run on this site with them and no results data for them. Same with the diy leds I've only seen higher yielding strains run. Veg time and strain play a super huge roll into what this disscusion is about. I could be wrong but i think @REALSTYLES only vegged for 3 weeks, and theres others out there vegging for 6 7 8 weeks. So comparing anything is still sort of up in the air. Id love to see some results from the lower yielding og cuts going around.
