don't know about per chip specs but here they are for the QB 288



  • 288pcs Samsung 301B top bin Diodes for V2
  • 288pcs Samsung 561C top bin Diodes for V1
  • Connectors rated 300V 9A
  • Estimated LER 321.60 lm/W

Does anyone of the esteemed samsung fans around here happen to have the LER

Hey, a little off topic but my little (5x5) QB chamber needs a carbon filter before I start flowering. I've got an AC infinity cloudline 6 blower, any recommendations on a good filter for this fan? 351 cfm

I’ve seen a lot of people recommend phresh filters. I just buy whatever decent priced/reviewed one is on amazon tho lol.

Again, think thats the standard 80 Cri. Ive seen some data around but im pretty sure it was for citizen or vero. Thx to both anyway
Pop, i couldnt believe it when i saw you growing Blu Mataró. Mataró is a small village about 30 mins from here, outside Barcelona. Will be following that one

Edit @Stephenj37826, you wouldnt have data on LER for lm561c 3000k /90 cri?

i'd personally recommend Mountain Air, ive been running one of em for nearly 2 years in a 4x8 and still no smell. they are pricey though...

also seen phresh filters mentioned a lot, too - dont skimp on carbon filters imo...specially if your freedom depends on it.

Wife has been figuring out the camera slowly lol. I am just sticking with my phone for now.
Pregnant wife has been going well so far. We find out gender at the end of the month. :o
Haven’t been trimming yet. I do have a lot drying in my garage tho lol. Trim jail is coming soon.

How has everything been for you bro?

Yes that Poonana is some frosty ☃ bud!

Kannabia has some awesome strains! I grew their Thai Fantasy and that was some badass Sativa! In fact, too much for me I just can't tolerate pure/almost pure Sativa any more. i've heard the MB is a good, balanced strain and she grows well!

the light levels would be good but with hangers and heatsink height he's going to lose 10" of grow height. I can get my QBs to within 2 " of the top of the tent if need be, you can't do that with a cob! I've got 2 cobs in a similar tent, same height, and height is always a problem. A pair of QB 288 or 304 is going in to replace the cobs, I'd recommend them over cobs in a tight space.

A few luminus cxm22 cobs....would knock it out !

AC INFINITY is going to start selling their own brand of carbon filter. They look ok. Honestly, my thinking is anybody making a decent filter is likely using very similar if not exactly the same carbon, and filters aren't exactly a proprietary tech; it isn't rocket science. That being the case (and I'm open to being corrected), I really don't understand what differentiates a product like Phresh from say, AC Infinity. I think a lot of it is just old thinking from old times when carbon was hard to use/come by and certain companies made a name by marketing a solid product. Again, not saying shitty products don't exist, but I have a suspicion that this tech is much more ubiquitous since the time when Phresh was the only name to know.

Look around on ebay. I am not talking about overpriced brands, phresh, etc. The mark up is ridiculous and most of all this hydro stuff is mainly made in china and then re branded(Hydro farm). I just don't fall for the huge marketing game. I have used Vivosun and works well lasted 3 years or so.
