You can't run just one of those boards on that driver, min. rating is 114 V for that driver. Plus I don't think you'd be able to reach 150-160W at that mA, you need more mA power to get there. Look to the 2800 mA

I've read that plants like temps ~5 degree's F higher with CO2 injection. I've not heard that humidity should be higher, however I know that they are related to a degree. Everything I've read has said that humidity should be 45-55 %RH towards the end of flower. During early flower I think...

Okay, something like this may be the only good option. No one wants to consistently waste CO2 nor do you want to give up valued grow space if you don't have to. A full sized unit would cost SWIM between 2-3 ounces each grow -- ouch! I looked at your unit and it says that it only pulls 8...

What size dehumidifier do you use? Maybe I should purchase new dehumidifiers that are really little and can be hung with ratchet straps or put on top of a DWC container to allow plants to grow around it? The two flower tents are 5x5 (well one is 4.54 x 4.54 but whatever).

The QB 96 elites on HLG's site look really awesome. Does anyone have these or any experience with them? I'm not sure if that can be hung on their own or if they require fixture support? Would love to hear some experiences or info. from those who have tried them out -- that heat sink looks...

@pop22 wow buddy! Those are looking *AMAZING* what QB's do you have over those fine ass ladies ;)

Because at some point the tent is going to dump it's internal atmosphere (probably around once every 2 hours during lights on) and pull in dry air (if the dehumidifiers are external to the tent). Obviously sooner if humidity spikes. I'm worried less about temp's as the HPS fixtures are...

Hello all -- I'm curious what everyone does to dehumidify during flower. SWIM has two dehumidifers that each can fit inside the flower tents, however they will take up valuable space. SWIM also is using co2 in both sealed tents with controllers and doesn't want to waste CO2 either -- because...

Omg they have super cheap scrubbers of every size on eBay -- just get a fan and scrubber combo for less than $40 and have piece of mind. When I was young, dumb, and full of c....[hold that thought] ... I grew in an apartment and omg, the smell hit you down the hallway. The neighbors had to be...

A driver for each board is not efficient in my opinion. You're going to be generating a lot of additional heat and considering some of these drivers are around $100/ea or more, you can potentially add another board or two in your design for the same light out put, so why wouldn't you? Also...

Nice fixture @pop22

At 20" I doubt it would have the foot print to cover the entire 4x4 grow. He would need it raised to at least 24" maybe 36" don't you think?

I don't think they like to be called "he she's" anymore ;)

Where do you get your STS from? You find better results and less hassle than vs. colloidal silver spray technique?

Where is the OG anyways? We all seem more fixated on this issue than he is! Haha

Word to big bird @ ~1g/watt -- nicely done!

Of course the light was too far away, he had to have it raised up to light the entire grow space... I'm sure this killed him on that basis alone.

Thanks bud! That's super helpful. Currently have four HLG QB 324 V2's with drivers sitting in the dinning room. They'll be super helpful I'm sure. Especially since two 20 lb CO2 tanks, regulator/flow gauge, and Titan Saturn 6 environmental controller are on their way! Yay! CO2 ppm in the...

Are 4 QB 324 V2's an option? Each spaced out equally; driven by two 320 drivers (2 panels per 320)?

No way (in my opinion)... I just bought a T5HO 8 bulb 4 foot fixture for veg. I love those lights -- they provide an outstanding spread of quality light for veg. LED might be slightly more efficient (even though T5's are already extremely efficient), I think the trade off in having a better...
