MEDMAKER420's 2012 LED Grow Show - ICMAG Grow Diary

[perfekto]

Hey. what homepage do you buy these brand : BLUE LED?.

and since you seem to know pretty much on led's. could you answer a question i got?. if so here it comes...

In grow stage what LEDs do clones and mother's need?
is it blue and white?.

and you can get like 1,0 / 1.3 up to 2gram per watt on hps lamp they say. is it possible to get 1gram / watt on LEDs? or even more?.
for this i know that the plant should be avoiding stress moments for being able to get a good yeild...

Someone told me that 300watt LED can give you the same amount of yeild as a 600watt hps lamp is this correct?.

for the moment i got a 209watt Apollo 6 lamp for flowering. will be ordering more..

one question more. how do you count led lamp's power drainage?. i mean they say led doesn't drain as much electricty as hps does

These panels are not for sale right now. I am testing different spectrums and different manufacturers and different panels for growblu.com

You can test your panels with a kill a watt meter to see what sort of power your light is using.

As far as the yield comparison, I am not one to pitch the leds can outgrow hps. I believe in hps lights and I am starting to like LEDs more and more.

On the yields, I don't know what these different panels will yield to be honest since I am running multiple strains which are from regular seeds so who knows what phenotypes might pop out whether good bad or great.

I don't like the ads pitching 300 watts of leds killing 1k watt grows yield wise. Can it happen? Sure but that is grower, environment and strain dependent. I don't think just ANY GROWER can outgrow ALL hps grows using half the wattage until they dial in their grow.

We have all had many years to dial in our hps grows and many ( including myself ) are new to growing with leds even though we have been researching and reading up on them for years. There is alot of growing that needs to be done to really figure out what panel is needed, what spectrum as well as which strains perform best under leds.

On the veg spectrum, I tested 4 different spectrums so far and all were variations of blues and all seemed to do well ( in the end ) but 2 of the panels were either too strong for the germination / seedling phase or I needed to back the lights off even more. I tested more seeds under all 4 lights with the panels moved up even further and had better results.

I am unsure which spectrum works best BUT I can say that most lights can veg plants and it doesn't take that much wattage to get the job done.

I would love to test without fans but among many reasons not to (like what you brought up) it is best to just get its watts as it sits

I suspect the amount of power the fans use relative to the amount of power the LED's use is so insignificant it's got to be all but irrelevant.

loving the new light so far

loving the new light so far

Can't wait to finish up the "sexing the plants" video and images at the end of the week and see what females I get to flower out.

 

[medmaker420]

Added a couple more updates to my grow journal including pics and videos. The kill a watt meter I ordered off of amazon came in so I took pics of the different wattage readings from the 5 different led grow light panels I currently have.

I also did a cloner video and the start of flower / sexing the plants updates for those interested. Just click the journal link in my sig and it will take you to my icmag grow thread.

 

[medmaker420]

click the image below to go to my grow journal thread to see the latest updates


A ton of new updates have been posted about the led grow updates from the veg and the flower led panels. I am uploading kill a watt meter readings for each of the panels I am running ( currently have 11-12 led grow lights ) and will have video and pic updates on the way in the coming week as well.

ALOT TO GET DONE but the show has just begun

I've been going through some rigamarole with Byssen recently and I think you are testing one of their lights judging by what they look like and might be interested:

My unit is supposed to draw 140 watts, it's the 4 round module unit with 80 led's.

I've got it plugged into a wattmeter and monitor it all the time. It comes on at 3am and goes off at 3pm to take advantage of the coldest times.

Due to the power regulation heat protection system we talked about before, it powers down if it's too hot then back up again to protect the led's.

So far at any ambient temperature above 21c I get a reading that varies between 117 watts and 112 watts at it's lowest (I think that was at 23C).

However my wattmeter has a maximum draw feature and it *does* draw 141 watts at some point that I miss out on. Likely at cold startup at 3am.

So perhaps it draws 140 only for a few seconds then plummets as it warms up.

I advise you when testing to keep the wattmeter on and compare during different ambient temps because I suspect these units are programmed to be excessively cautious in their LED preservation circuits. They use quality LED's, so I"m not sure why the can't be run at half capacity all the time, why do a few degrees ambient around room temps make any difference?

Also my Byssen unit sucks hot air from the top and blows it out the bottom for cooling. I've asked, they say this is by design because it's good for the plants and "no one else has ever complained". I thought I saw you saying your unit blows upwards sucking in cooler air from below can you confirm that because these guys are telling me I'm crazy for thinking that's a good idea?

Great questions, they all suck from the top and blow out, I thought the bysens were opposite but it was just the airflow back pressure I think I was feeling on the tops. I agree about the fans needing to be switched around and suck from the bottom and blow UP.

I was actually planning on modding the led panels I have to do exactly that BUT not messing with these anytime soon until I get plenty of grows out of them however as I keep growing with these panels the whole heat issue really isn't an issue so I stopped focusing on it. I think I was still stuck in my hps ways or something lol.

Yes these manufacturers in my opinion have the fans running BACKWARDS or they are clueless to tent growing and the fact that all hot air NEEDS TO rise up and not be sucked back down. If you have an inline fan however these fans and the air it is moving really isn't an issue though.

If enough bring it up maybe they will research it themselves. I would like to see a surface heat temp test with the fans going both ways while being hooked up to a watt meter to see what changes happen.

As far as the wattages, I have tested these and posted video and pic updates in my grow journal thread. On the wattages though I never go by what they are saying and most are ran much lower than what we assume they should run at.

For example I have a few 200x3w panels and they all average 300 running watts whereas in my head I would think that it would be in the high 400's to low 500's including fans.

There are alot of things that I too am questioning with the different grow lights as well. Right now I have 3 or 4 different manufacturers lights that I am running including micro panels and they all have many pros but also with that comes a few negatives like the backwards blowing fans for example. I wonder what the effects on the heatsink would be if the fan was being sucked in and then over it versus blowing straight down and then across.

Have you thought about switching the fans around? If you do please keep me posted on your findings.

Hi guys... You know, I could try writing a letter to my 'friend' over there at Bysen and asking if she can find out from the techs there as to why they have the fans in that orientation...

I'll let you all know the answers.......if I get one that is...

It was one of the first things on the different led lights that I noticed and had me ask growblu right off the bat as well. Not sure if they brought it up to the manufacturers or not but odds are they got the same sort of semi answer everyone else has gotten.

I think if enough keep bringing it up though it might get ironed out or at least tested.

 

[vukman]

Below is a copy and paste of the email I got from Bysen.....

About your question ,I have the answer yet ,
I could fully understand what you want to express,
I asked my manager just now ,He said it is a easy question,
Take a fan For example ,
When you stand at the back of the fan ,but you feel the wind from the forward ,
The wind blows in from the back of the fan ,but blows out from the forward ,
So the principle of work of the led light is the same as the fan ,

May be you saw the air outlet at the side,the warm wind will out form the side ourlet ,
Look the outline carefully,
You will find it is different from the other lights ,
the special design to be used for waterproof,
If you know what's my meaning ?
That's the language difference,

we have tested the two ways ,but this design was proved to be a good result,
it benefits for cooling down the temperature ,
Wish you could understand me a little ?
did you ?
yours,

My email was better but basically it all boiled down to "that's the way we do it" and no real explanation like that person at least tried to give you.

I still think the much bigger issue for me is the lower wattage being drawn (112 at it's lowest at common grow tent temps). I just feel like it should be able to fully handle a 75f / 24c environment without having to dim the lights.

I've noticed that it's consistently drawing 121 watts now that the temps are down to 70f / 21c and that's actually what I would expect it to draw if it was set to never go beyond half the rating of the LED's. If it could truly put out 140 watts as advertised at room temperature even better but I don't think they can.

Sneak Peak

Sneak Peak

Here are 4 of the led grow light panels in their new homes. The other panel is in its own 2x4 tent. Each light will get a 2x4 flowering section for testing purposes.

 

[Phychotron]

what type of fixtures are those?

 

[vukman]

nice bro, nice....what are those?? Bysen and Apollo's or they Eshine?

Whatever they are,,,should be an interesting go of things....as usual with you..

 

[medmaker420]

what type of fixtures are those?

A couple different manufacturers being tested, these fixtures are all different spectrums though so that in itself are their own variable as well.

VUKMAN thank you for the kind words and hope your grow is killin it as well brother. Your lights look a bit like some of mine as well but we are all rollin with different spectrums. Got to love testing lol.

 

[vukman]

Yes..so true and that was my bad about my post and I want to apologize in public brother.. it's not my place to name name's and I am truly sorry about that..

The manufacturer's do not matter in this case because GrowBlu.com (not sure of spelling of name).......has their own proprietary spectra and wave length ratios which is only known to them.

To achieve the same results as brother medmaker420 aka Aardvark.......you need to get the GrowBlu lights..........going straight to the manufacturer in this case will not get you those same wave lengths and ratios......

My bad bro...................sorry

Do not apologize brother because there is zero reason to.
There is nothing wrong with your posting info in the least. I think apollo, eshine, bysen have been mentioned throughout the testing threads and conversations here anyways.

I agree the ratios are all unique but as I have said many times most of the top led grow light sellers all use the same 3-4 manufacturers yet pretend they are making them in house. Growblu states on their website that they go through multiple manufacturers however like the apollo style light I have found that through 3 different places so far or ones that look so close its hard to tell so while I think I know where some come from I am not 100% and honestly am still trying to blind grow test these as best I can without focusing on manufacturer or the spectrum the plants are growing under.

I am not even trying to focus on the panels wattage in flower either because being used to growing with multiple 1k watt bulbs and going to around 1500 watts in total makes me want to estimate yields already and I do my best not to focus on anything that my affect my grow tests atm.


As I said though, bring up ANYTHING you want. I am not here to censor anyone.

Here is a picture I shot today ( more can be found in my icmag journal )

For those who haven't seen the different led grow lights I am running right now don't forget to check out my grow journal thread ( located in my signature file below everything I post ).

 

[vukman]

As I posted in the main thread already brother...!!!!! hehhe

Great results....must be something in the water...
