DIY with Quantum Boards

[BuddyColas]

They are just babies. lol. so i could drop my lights down, or just wait for them to get taller.

IMO, you could dial that down to 25,000 LUX for about 360 ppfd and your plants would be happy! That is my opinion...your results may vary!

What is the max current and voltage a board could take ?

In case wired in parallel and a board failed sending more or all current to a board?

When you say primary and secondary you just mean input and output correct.
I will be powering the drivers with 240v so I can draw less current and don't have to change existing powering setup.

I assume output of driver is the same regardless of input powering choice 120 vs 240v.

Correct. 240v AC is actually 120 vac to ground or common which is not the same but it is. Both main lines must be fused on the primary side on 240. The secondary side nothing is grounded, just floating.

Any new plant pictures today? I want QB board flowering plant pics.

Any QB people thinking about adding red diodes or blue? Any way to add UV or UVB or is it a waste of time. Thanks.

Well here's what I'm doing


Almost done with it had something come up so I had to stop but will finish it tonight.

Where did you get those hangers laying on the ground?

They look like the cheap hangers that come with Chinese burple LED.

Check northern grow lights for hangers

Just ordered 4 boards! Woooooooooo!

now to get a HLG320H-C2800b!

Or a HLG 320H 1400 B

It is not an enclosure.
It is a heatsink just like the one that is on website right now . Just 3 X longer so it can fit 3 boards.

So 3 QBs in a 4' long row, each powered about 150 watts and I would have an even better fixture than the Photon 450?

You would do a 320 1400 for 4 boards instead of a 2800?

That's what he used for each of the two 4 board fixtures I'm running in my overhead experiment. He mentioned wiring them as two in series, and each pair in parallel.

Check out this series parallel config. I like this better than all 4 parallel.

3x boards DIY will be cheaper.
Hard to say which one is better. Both for different audience.
Photon 450 will have reflectors optics and lot of cool features. But not an ultra high efficiency that you can do with DIY

This driver powering stuff confuses me a bit I must admit. I need to figure it out because it frustrates me not understanding something.

Waiting on some parts and a plate. Can't wait to to see what they can do. Going to flip in a week, hopefully I can get it done and ready for this round.

Omg. I am gonna cry. So jealous.

Are the black panels the heatsinks. I cannot wait to see what this becomes.

 

[1000ppm]

Yes those are the heatsinks.
