DIY 4x12 3500K/5000k lm561c two channel board

I got a quote for a nice heatsink from BAL aluminium. Uk.

http://www.bal-group.com/heatsink_detail/200.

450mm long, £53.46. - $71 us
Transfer included they said. I take it that means free p&p

Poweralia has nice deals on heatsinks, pretty sure youll find 1m at the same price that BAL is asking for for half a m. Not sure about shipping though

Thanks, never heard of them.
I'll check it out

 

[Moflow]

I've fired them off an email, just awaiting to see cost of shipping
Thanks @Rocket Soul

They have some heatsink profiles that pretty much looks made for casing and venting, like if you had your heatsink in a cooltube. Very cool for high wattage application.
Also, but im not sure if i got this right: i could get it shipped for cheap and pick it up as they have a site in my town.

Yes , they have great prices .
£60 / meter. 1m = 2 x Heatsink for me
Maybe I'll touch lucky with shipping but as I live in the in a one horse town I'll not count my chickens.... lol
9 kilos per meter it weighs.

Glad to share a resource, no point in anyone paying more than they have to

Here is a completed frame with a power switch and daisy chain power connector for connecting multiple 400w modules into a single outlet.
Power switch with connector is typical pc power connector with a second power connector no switch. Both readily available on ebay.
I use three wire conductor for connections 14 gauge typical and female spade connectors for connections.
Add two pcb's on heatsinks and you have a 400w module. Mount two HLG-185H-C1050B drivers on top and you have a total modilar fixture.
Each can cover a 2x4 area. Two fixtures can cover a 4x4 easily.

Update: 40 days of flowering.

Back left, Strawberry Banana, Back Center, Wappa, Back right, Sensi Star original.
Front left, Sensi Star 2, front middle / right 3 x Bubba's trainwreck haze #1.
The 3 trainwrecks were regular seeds , they're in 7 litre pots. In there to find out whether any are female.

I've the gg boards still running at 150 watts each.
QB is at 130 watts and the 5 x cxbs 3500k, 200 watts
I have another 2 x Mk2 gg boards sitting in reserve, awaiting heatsink from Spain.
Big shout out to @VegasWinner for sending the boards!
Things in the garden are looking rosey
The strawberry banana is huge.
All the plants are starting to frost up nicely.

They are hand watered. I am currently using Tomato feed, Grow-Sure it's called.
NPK 6.0 3.0 10.0.
The banana and Wappa got a feed of 1.1 ec, the 2 stars just got water yesterday.
Thanks for looking in

Great grow. The girlz are fattening up nicely.

That original Sensi star is gorgeous. Is still possible to get seeds of that?

Paradise Seeds Sensi Star.
The Original one is about 10 years old now.
The ss2 is about a year or so old.
There are a couple of phenos to be found in a 10 pack of seeds and we touched lucky with the Original one.
I like both.
I'm not keen on nets, support, for the Original, it flops over otherwise but, as it's in a league of its own it's here to stay. It's quite a finicky plant to get right I find. Lots of trim for making oil and buds can be leafy. Tastes fantastic
The ss2 doesn't need any support, with nice buds from top to bottom with hardly any trim to speak of. Good smoke too.
I always clone seed plants in case a good one appears.

These boards sound great, can't wait to get an update on new supplies after the 15th

Shenzhen returned from their holiday and everyone is back to work.

I am asked on a regular basis why I mix 5000K diodes with 3000K diodes on one pcb and two channels.

I chose to go this route as it is a more cost effective manner to add more 460nm - 475nm light spectrum from the 5000K diodes and add the 650-700nm Deep Red in the 3000k diodes for a great growth combination.

460-475nm Royal Blue is considered for the ability to reduce stretch in plant growth. That is one aspect, but there is a more important aspect to using 460-475nm light spectrum throughout the growth cycle of cannabis and all plants, that being 460-475nm light spectrum provides an energy boost to the plants growth process. There is another aspect to this light spectrum, as well, is it adds flavor and aroma of flowers during the flowering stage.

In daylight, there is 460-475nm light spectrum in the light all day long, all year long.

650-700nm Deep Red is mostly considered for adding stretch to plants during flower phase, but there is much at work. 650nm -700nm allows peak chlorophyll's and photosynthesis , already well known. Perhaps lesser known is the ability of 650-700nm to increase antioxidants and improve flavor of flowers.

So both light spectrum work together to enhance flavors, size, taste and aroma. All that is left is the THC development, UVA, another discussion.

One method to provide The necessary 460-475nm light is to add a channel with Royal Blue diodes at 460-475nm as other's have done, or to add the 5000K to the main spectrum available, which peaks at the 460-475nm spectrum, great for adding that additional light spectrum at a less expensive cost and still get plenty of "white" light and watts.

The same is true for the 650-700nm using the existing in the 3000K light spectrum. The 2700K light spectrum will provide a little more additional 650-700nm and the 460-475nm will provide the additional energy needed to take advantage of the 650-700nm light spectrum enhancing growth during vegetative and flowering phases.

thank you @VegasWinner
For your contribution and love for the community .
Your operation is inspiring to say the least .

I love sharing. Thank you.
Interesting observation at 100w LM561C is delivering 190lm/w for a total of 19,000 lm at 100w. At 200w the LM561C delivers 170lm/w for a total of 34,000 lm at 200w.

If we're supposed to wire the channels in series for a single board, I'd recommend on the next iteration flipping the positive and negative side on on channel that way the channels line up as follows:

C1 C2
+ -
. .
. .
. .
. .
- +

For ease of connection. Otherwise great board, cheers! Out of curiosity, what are these connectors called on the pos and neg?
