Your plants are looking bomb, mate. Can you tell us more about your panel? Seems to be doing a great job to me. What strain is this?

Panel is homemade, and consists of only 3x 30W Cree modules (8 red, 2 blue in each), driven at 24W each.
So it's not a lot of light, but it seems to do the job. For my next grow I will add more for sure.

I don't know what strain it is, it came from a mix bag.

If it's not a trade secret, I'd love to see some pictures and explanations on how you did it and what exact modules you used. :D

Share the info mate, it seems to be doing a very good job that would potentially be beneficial to others looking to grow in a similar manner.

Of course it's not a secret - I'm here to learn about what I don't know, and to share what I do know :) The modules I've used are these: http://www.topledlight.com/30w-cree-led-emitter-30-watts-red-blue-grow-light-diy_p1096.html

Each module is driven by a Meanwell LDD-1000H, which is a 1000 mA constant-current buck-converter. The power supply consists of a transformer, diode bridge and capacitors.
The mounting isn't pretty, but that's what I had lying around - and most important.. it works!

look good, a little more light and a little less nitrogen in flowering next time would do wonders, hope you get your hydro system up running, what kind was it ?

Thanks I'll remember that :) The hydro I bought is a GHE Aquafarm 45 L.

Good shit mate, this is great. Simple yet very effective. Hi-powered diodes do the job. Would you like to venture a guess on yields?

Not sure yet. But they had a very rough start with way too little light where they almost died. The pots are also way too small (about 1 gallon), but that's what I had and I wouldn't wait :)
I'm gonna harvest it tomorrow I think, then I'll post wet weight.

Next is going to be a 45 L hydroponic! Major change up.

I'm about to start my next grow, but the auto seeds i got from Royal Queen Seeds are having some trouble germinate.

Will post new thread when next grow starts.

I'm very happy with them. Been thinking of getting a few more, or the ones with warm whites.

Good call...step up to the 50w warm white modules as your main points of light with your existing 30 watterz quietly doing their thing in the 'background' :)

Yea, I've been looking at those. My drivers are only 1000mA though, so I might have to fix some new drivers.
It's fun to test various approaches :)
