Wanted to bounce an idea off you guys.
My next grow I’ll be getting a 4x8 tent.
I currently have 3x260w 3k kits.
I am debating on getting another 260watt kit
Or
Getting 8 132qbs in either 2700k or 3500k.
Or
Strips which I do not know much about yet.
What do you guys think?
Thanks!

I'm liking strips more and more every day.

What area does a 4ft strip cover?
I’m either thinking 8 qb132s or 8 strips.
What distance do strips have to be at?
Thinking 2700k since it’s only for flower.
The area covered depends on the particular strip used and the power level it's operated at.
I've run Bridgelux strips as close as 8", but it depends on the power level of a particular strip.
What are the dimensions of the area you need to cover, the area not cover by your current lights? What are your current lights?

Yes the area not covered by my current lights.
Which are 3x260watt qb kits
Really just help fill it in and get better coverage.
Only problem with strips is I’ll want them to sit about the same height as the qbs which are ~16” give or take 2 depending on plants
Maybe get away with 4 4ft strips?

Samsung strips use the exact same diodes. Just run them at the same current per diode as your quantum boards.

Depends on hot hard you run them - but they don't need much. You can use cheap aluminum architectural channel for heatsinks at about $1.25 per foot.
When I more downtime I’ll have to see which ends up being cheaper and easier.
I’m not a big DIYer lol. But figured I’d try.
I’m thinking either 4 288 strips or 8 132qbs.
Thanks. Maybe I’ll have some time while I have a layover to crunch numbers.

Get a 5x10 tent if you got the room, fits 4x4 or 4x8 trays a lot better.

I run 300w of GrowGreen (3-100w pcb's0 in a 2x4 tent. For a 4x8 I could use just 900w of GrowGreen pcb's with an additional 200w of Royal Blue/Deep Red for a total of 1100w needed.

Most pcb's should yield similar characteristics overall lower watts, less heat, fewer amps of support fans, etc needed to achieve the same result compared to COB's or HPS.

Thanks for sharing but not sure how this helps me lol.
Is this a build you came up with?

Yes. I design my own pcb's and fixtures, and light controllers, as well for schedule. Each pcb is 100w of power with 384 diodes running at 88ma each. I use three pcb's for a fixture to cover a 2x4 area. Four of this style would cover a 4x8 area and only cost 1200w at 1050ma and 120v for a total load of about 12a, excluding fans. Each pcb is only 4x16 mounted on a 6x18 heat sink. think outside the box.

I'm torn between the 320watt qb kit, or making 6-8 cobs. Using citi cobs. With arctic coolers. Which do you think has better coverage?

Not trying to hijack your thread.
