DIY with Quantum Boards

50watt panel - Quantum

So far this little panel has been amazing . I do have more plants in tent with this main one and all are growing well. The GG4 is beginning to stack up and will highlight that one in a few days.

I began working on two NEW separate builds , one centering around THIS panel which will be modified ....

I expect the last of my parts tomorrow and will highlight those builds in a few days.
Budz it looks great ! I know with my 2 board build I can't run it at max with the two autos I have flowering. There just isn't enough canopy of plants for the light at max. Right now I'm at 150W total, 75W per board in a 2x2.5.

The next round I'm going full on scrog with a Nirvana Papaya to fill the tent with canopy.

Oh and for the doubters and naysayers in the past. Not only do the boards veg but they flower well too.

For a quantum? Why do you think it needs one?
Yep,
Simple sloped one much like the old hydrofarm hood
The boards blast alotta light out the sides be nice to reflect that down
I don't want optics as I like the spread just wanna reflect that side blast
I've got my kit qt on top of my refer in the kitchen the side blast lights the whole room as the refer is in a corner

Interesting. I'm looking forward to seeing your grow with it in place.

Also to anyone who knows COB grows. What the consensus on Watts per sq ft in Veg and in Flower ? I know there are a lot of variables but would like to know a ball park.
I generally recommend 20W/sq ft for highly efficient LED setups (25% or less of peak output per chip) to 40W/sq ft for LED pushed hard. I'm running my COB LED at 37.5W/sq ft and it's borderline excessive.

@robincnn you have prolly answered this a time or two but I just thought I'd get ur opinion
I wanna do a rack system in my closet it's two by two
I was thinking four boards two on top level and two on bottom and wanna use two drivers
Would these work https://cobkits.com/product/meanwell-hlg-120h-48a/ or what's your recommendation
Sorry for not paying great attention I guess lol the things that makes these boards great is they are easy for diy dummies like me I wouldn't know how to wire them either and I still get series and parallel confused but these things make it so easy

i always end up at max 50 watts a sq foot. i build them up to that in my flower tent start them around 200 and ease my way up. i do grow auto's if that makes any difference

edit not that you need that much i have seen great growth with as little as 25 watts sq ft

HLG120H-48ais driver peaks at 54 volts, quantums require 105V+, it won't work
