ok got it.... I dont plan to do 5000k mixing + 2700 panels. So lets suggest what to order 1. 3000k or 3500k? for whole round (veg/flowering) 2. for Mother plants only 4000k or 5000k? 3. 660/730nm chips one day china supplier tells me 12usd for strip with like 48chips, next day is problem to produce ...

This has been well documented and even lab tested. Mixing spectrums of white LEDs with the same CRI results in the mean spectrum being dominant. To each their own (on other thread someone was writting me that is no sense to mix 1:1 as its the same as 3500k, but 4000k has more blue so plants could g...

aah ok ...

So either by counting each panel Current (AMP on -CXXXX series) or Voltage (48 / 54) i can pick right driver

so for 2x QB both could be right:
a) HLG-240H-48AB
b) HLG-240H-C2100B

interesting...

Ive checked here
https://led.meanwell.com/webapp/product ... d=HLG-240H

its mention is like "12V/15V/20V/24V/30V/36V/42V/48V/54V" but they do also MODEL marking with "AMPs" values

so is 240h-CXXXX (and silimar) some new way of naming?

yeah the total size of such frame (6x QB) will be large and maybe an issue to hang it first time. So the idea with 2x frames (3xQB) could work as you mention will connect the same 2 middle QB with HLG-240h-48b and later for Flower 4 rest QB with HLG-480h-48b, BTW what is the difference between: HLG-...

Frame is just example - but i want to build something similar , i keep in mind that distance suggestion QB size should be 286*174*1.6mm If i would do your 2x frame setup i would need to put 3x drivers for those panels + 1x driver for RED chips With my frame plan is 1x driver for 2x middle QB and 1x ...

3000/4000k mix 1:1 is meant on 1x QB so 144x 3000k/144x 4000k chips so light color temp will be equally spread on each panel. (on other thread someone was writting me that is no sense to mix 1:1 as its the same as 3500k, but 4000k has more blue so plants could grow a bit more i guess :roll: ) Panels...

i live in EU so HLG / Atreum boards are not option. yeah 150x150cm box. My plan was to use 2x board on like 50-70% only for veg and after 10-14day put additional 4 boards (6 in total, to have light/chips equal on whole area) + 660/730 nm strips (red parts on picture). Planning to order them from ali...

hm do u have some details to this?

As ive checked 4000k has more blue so i wanted to reach better growth....

If they are able to build it for same price (30-40usd) like 3000k or 4000k, why not?

But im open to get more info on that...

That looks sweet.

How much would cost 4x 4 foot mounted on heatsinks to EU (Czech Republic) ?

je to z US takze dost

From US to EU i assume around 100-140usd + tax / customs
