Is there a mega crop thread active on a different site?

I'm confused... QB324's are 54 VDC I thought? And max. mA at 3200 mA ? Why wouldn't 320-c2100's be enough to run two boards?? Why can't you run two of these boards on 320H-C2800?
I can't find a Flux chart nor does this voltage driver stuff make any sense to me...? Thanks

Depends if they are the V1 or V2 boards. V1 are 100+ volts, V2 are 54. Sounds like he has the V1. And that driver is perfect for V1 QB 324 boards. You can't run the V1 at 2100ma that would be pushing about 240 watts thruogh 1 board! the are rated to 150 watts. In parallel they'll be drawing about 115 watts per board, about the same as a QB 304. You can run a pair of V2 QB 324 in series on that driver. I run 4, QB 304 on a 320H-C2800 in parallel for 85 watts per board and that's plenty in my 4x4 tent.

Mutiny in the ranks!!So.... Megaxrop users, are you sick of the RIU bullshit? I'm trying to talk the guys into telling RIU to fuck off and become active on AFN. I thought forums were suppose to be for the members, but as usual, the almighty buck rules..........Grrrrrrrrrrrrrrr
ok rant over. Sorry for the off subject.
What is AFN?

Ah that makes sense now. I wasn't thinking outside the box.
Think I will pass on that. Autoflowers??
RIU has its pros and cons. The pros out weigh the cons for me.

I am about to check it out. Never know where you learn something.Ah that makes sense now. I wasn't thinking outside the box.

Never tried autoflowers.

Their focus is autoflowers but the forum covers photos also. I grow both. and its well laid out and offers good information. And unlike RIU the mods there don't allow bullshit. You start talking shit there and your gone PFFFFT! Trolls last maybe 5 minutes. Its worth a look. Might find a second home. Its my home base but as you know, I'm here a far amount also.

Thanks -- do you think SWIM would be okay to run 2 x 324 V2's on a 320-C2800 in series? My math tells me that it's enough driver. Is 2800 mA too hard? I've read that 324 V2's can be pushed a bit harder and up to 3200 mA max. What are your thoughts?

I never understood the appeal for indoor growing myself for auto's. Everything can be controlled, why rush things for a smaller and less potent yeild?

The 320H-C2800 would work fine. I haven't seen specs for the V2 but considering the chip count is not that much more than the 288, i'd think 2800 would be max. Even with this driver your looking at 140+ watts per board. I've got a V1 running at 117 watts and you need suntan lotion around that beast!

Okay thanks. SWIM will purchase four 324 V2's and 2 Meanwell 320-C2800's (one driver per two boards). It says that the 324 V2 can go up to max. 3200 mA but I think you're more limited by the heat sink. SWIM will get the heatsink 2's and was thinking about order a computer fan to wire separately to rest on top of the heatsink to pull heat off the sink.
SWIM probably won't run these at 2800 mA on blast, but rather keep them turned down a bit since they'll be in a tent with HPS 1:1 until SWIM can purchase some more to run 2:1 QB:HPS

Things have changed a lot as far as autos go. Many strains now testing THC at 20% +, Mephisto has a couple that hit 27%. As far as yield, DP has several strains that can drop a pound+ plus of bud. I believe the current record for an auto is close to 2 pounds. I grow both and I'll put my auto bud up against the same strain in a photo period any day. This isn't Lowryder crap! And there are small so so photos also. You should take a look at what's available today. Only real disadvantage to autos now days is you can't clone them. Well, you can but most clones don't amount to much. I have however revegged an auto and got a nice second crop from her. I grow either as the whim strikes me.
