You mean 2 times 300Watt... the buds you see are grow'n under a 300Watt spectra unit. the lights hang very low, and LED can only shine stread down... So if you really need too compare, compare it fair...

For me its not about saving energie. its all about bigger buds.
I think this is the way to give yur plants more light than ever. If i could i would even put more wats in there. 1200Watt LED system orso.

I allready know what i can do under 600Watt HPS. But what we can do under LED is still in the dark. thats why, last year I called this LED company that advertises in Highlife. I asked them if I could test their lights to see if their up to it. I allso told them that any result good or bad will be publiched by me in Highlife mag. maby softsecrets and on the internet. They found that no problem convinced that their lamps are oke. Whe talked about HPS and LED other light. I asked them for the 600Watt LED lights, cause they wer compairng the 90Watt whit a 400HPS or even maby a 600W. So i told them why not compare a 600Watt LED with a 600Watt HPS. just to see waht LED can do as far as we are now. We can allways go down in watts..
They didn't have a 600Watt LED unit at that time. So I started to test what they gave me instead.

So from than on i'm testing whit the ufo lamps, the 80/10 red/blue , the 90blue. this didn't go that well, lots of stress in the plants and I didn't know what to do whit water of nutes , the temps wer like shit. lots of probs. But I still harvest some buds.

In the meanwhile I stardet to study light, spectra, and the needs of the plant concerning light.compaired my study to wath i see happening under the LED's with cannabis. I asked the LED company to send me LED spots of diferent colours so I could expiriment with these collours on cannabis in her different stages , in combination with the LED lights I allready was testing. They liked the idea and sendet me all kinds of LED spots to exprirment with. And to make a long story short, I gave them al the info I got from these tests and told them why not copy the spectra from the HPS green power master sont + and put that spectrum into a LED cluster. Allso you need to put UV and Infrared into the spectra...Well they listend and as far as they could they broutend the spectra, and they came up with a other light. this one had a brouther spectra and should do better. So I stardet testing that one to. Meanwhile I'm publiching everything that happens in detail.


Than I got a call from Dutch Green Grow Lights, ''hey Dokkie, Its ready, I got the 300Watt Spectra unit with extra UV-a and Infrared, and some other colors, wanna test it?.
Yeah finaly!, cool.....So i made some space placed me tent and mounted the two 300Watt SPECTRA-UNIT's inside.. Now I can grow some dank bud under these freaking LED's. And we'll see what happens. maby it still needs more colours or different colours in its spectrum, but heey i'm no einstein. I only know, that I will know i a couple of weeks what this lights can do. just like with the Spectrabox 90Watt. Because I tested en publiched that test with detailed pictures, everyboby can see for them selfs wath these lights can do.

And now its the same whit these 300Watts, I wanna know too.... I wanna know if these light are what they say they are. And i am most critic and sceptic, believe me. If turns out to be crap , I'll publich it to. But I am allso positive and I think these lights will suprice us.
For me personaly its like a cool thing to test. It expance my hobby a bit. and its a challence to do this..
it gives me lots of stuff to think and write about, and peeps wanna know if these light are any good, anyway...now you know why i grow under LED.

And personaly I don't give a shit anymore about peeps making money in the cannabizz with new toys, products and or big asumpisions, there is always this geek who is gonna test it and publich it all...


All my story's and grow reports, experiments like this one are publiched in de softscets EU magazine's and the Dutch, Highlife Magazine.

grtz,


Dokkie

wow sound like you realy did your homework i congradulate you and hope you continue producing killer buds and paving the way for LEDs and showing every one that there future is very promising
+rep

and i agree with giving the plant light it can use..

This is the best LED grow I've seen to date and I've looked at them all, believe me. I'm still not convinced they can replace HPS (although it's getting there) as the volume of growth does not look quite there. Dokkie's buds look awesome here, but it's not unheard of to get 200g of bud and an equal amount of popcorn for hash from 600w HPS as you can grow bigger plants. These LED's look perfect for SCROG or SOG but when you're limited to only 6 plants by law, size matters.

Keep up the good work.

Not to include this guy is using soil! Imagine Hydro with these lights...

Im at 36 days into flowering with 3k HPS and my buds are no where near yours...

Im beginning to worry, My room temp with lights is around 87. Could that be the problem?

+rep for a great thread. I'm thinking about investing in an LED setup soon and this thread was inspirational. I'm moving pretty soon and I might set up an LED grow room so the thread was useful. Thanks

As i'm reading the Softsecrets 03-2009 page 16. right bottom of the page, Its article from Ed rosenthal. He says that we can keep the pure blue light on at night!!! the flower cycle wont be desturbed and the plants will benefet and give bigger buds...

I quote Ed Rosenthal:" plants use blue light for certain regulatory processes and also for photosynthesis. Chlorophyll absorbs both blue and red light and uses the light energy to power the complex process in which water and atmospheric carbon dioxide are converted to sugar and oxygen gas. Blue light does not affect the regulation of flowering.

When blue light is turned on during the dark periode, plants photosynthesize but their flowering isn't affected. This results in more growth as the plants produce more sugars. Before LED light it was diffficult to create a pure blue light. Instead, most of the time other spectrums were filtered out. Which can be an inconvenient process.''

So next LED grow, that will be whit one 600Watt Spectra unit. I keep a pure Blue LED light on during the dark periode...
