How's it going fellow LED Growers. I finally had the time to post up my ICMAG Grow Diary which you can follow along with at:

https://www.icmag.com/ic/showthread.php?t=244897

I am running 4 different veg lights currently and have 6 flower lights headed my way. They are all different spectrums so who knows what will happen



There is so much led grow light testing needed to be done and I hope you all subscribe and chime in from time to time with words of encouragement and advice!

Good luck and make us proud!

I posted up a ton of videos and updates in my grow thread ( in my sig )

- week 2 veg update video - shows some yellowing which I am fixing with an up pot and their first drink

I can't wait to get the girls up to size to start the flowering side of the tests as that is where all eye will be.

Posted more updates in my grow journal thread. Feel free to post a comment in my grow journal thread ( linked to from the first post in this thread ) and get your screen name mentioned during my next youtube video grow update.

How are you liking lights 1 & 2? I really want to buy a set of these. Any chance you could get a kill-a-watt reading on them?

I am LOVING light #1 and #2 compared to #3 and #4 personally. Out of the #1 and #2 its still a toss up but one thing I will be talking with growblu about is testing different led angles as that too can be customized and I feel having 30's 60's 90's and even 120's in certain instances during growth could be beneficial.

I will be getting kill a watt readings from all 4 veg lights and the 6 flowering lights when they arrive. I also want to do watt tests with the fans disconnected as well so I can get a REAL light wattage amount for the different led panels.

Just remember that both light 1 and 2 are different veg spectrums as are light #3 and #4 and not the "stock" units and spectrum you would be getting from the manufacturer but once the testing is done growblu will then buy and then stock their custom panels here in the states.

These 4 are being tested not only to find out which manufacturers growblu should order from but also which spectrums that they will be selling for the veg, flower, full spectrum and micro panels.

Yea I'd be ordering these straight from China so I wouldn't have the same spectrum as what you and GrowBlu have got going on. The "default" spectrum includes lots of deep reds (660nm) so it should be good for flowering.

From what I understand it is desirable to have a wider lens angle (like 120*) during veg because the plants don't need as intense of light, but in flower it's best to have either a 60* or a 90* lens and adjust the height as necessary to maintain high light intensity. You know what would be interesting? Mixing LED angles... I wonder what effect that would have on PAR rating and light distribution?

Great idea about disconnecting the fans before taking a reading as well!

Man I really want to get these now! Thank you for the consistant updates, hopefully you keep this up because it will give me a really good idea if I want to get these lights or not. What spectrums are the flowering lights they're giving you?

[medmaker420]

On the flowering spectrums, I am uncertain but I do know they are 6 different spectrums just like these 4 veg lights are all unique spectrums as well. They are trying to pinpoint which combination will be best for marijuana growth overall as far as veg and flower goes.

I asked not to be told the spectrums each light had so my grows wouldn't be biased in any way as I have done my own led research over the years and feel that I know what works best BUT didn't want my "opinion" to sway the results and just let the plants do the talking.

In flower I will be testing more manufacturers than the two I currently am however so there might be lights that perform and work BETTER than light #1 and #2 so that will be a blast for everyone to checkout as well.

I will also be doing vertical grow tests as well as led light mover grow tests among a few other fun ones using ir/uv so by all means continue to follow along.

Later I want to do an all blue flower tent just to see what happens using the veg lights. This test will be done after all the tests they want me to do however because it is something that I want to test just to see what would happen without ANY red and see what the plants do.

On the mixing light angles, you will see me writing about that plenty in different led threads here and totally agree. Different angles for different stages of growth as well as where they are placed in the panels themselves would be very important to optimize.

Can't wait to check out your grow show once you get the leds so please pm me the link so I can follow along as well.

If you really want to be blown away, check out 'plamsa sulphur' lights!! LOL...now there is some serious lumens!!

Lumens is for humans eye, right?!

Sup Bro? No update, no answer, no opinions?! I don't want to hurt your feelings about asking from HGL products. Are you associated with HGL?!
