I did a run and used the 90 degree angelinas. A few weeks into flowering i actually took them off on some of the COBS as some of my branches were quite high and the anjelinas cast a shadow. Mind you, my COBS were about 6 inches away from my canopy running at near 50w @ 1400ma. Didn't experience...

You need to have a look at how refrigerative AC's work. It recirculates the inside air i believe and doesn't actually suck anything out

The ultimate active cooling

Hi Just about to purchase some 600H's got a few questions . And godamn they are expensive here in australia! Price is 283USD TO 610USD + !!!! I'm not kidding. Anyway i found some in China for $183USD posted. 1. Has anyone figured out if the A series is fully dimmable yet? Or are we on the...

Hi Mark, None of those custom brackets in yet? Also, any chance you can do a good deal with the Growmau5 kits without the drivers? cheers. BTW , nothing seems to be in stock atm?!

I think my ideal driver would be HLG-600H-36A Any chance of you getting that cutter?

Are there any drivers that do 10 x cxb3590 @ 1400ma?

Not so much of my LEDS but finally got my control system up and running. :)

Please let me know when the brackets are included. I'll purchase then! :D

Been meaning to ask this. I have a cxb3590 4000k with a ZPE 60w driver. @1.4a Is it possible to add a 5k 3590 in parallel with that driver making each led run at 700ma?? And driver failure won't be an issue because each drivers heatsink will be fine with 1400ma. Also, last time i used my...

Had my heatsink about 10-13 inches from my 600w mh and this was what happened. Gave it a very nice colour. Anyone know why it would appear this colour and not silver like aluminum?

Dimming on the last week here to save on some power lol

You are looking too deep into your electrical dude. You claim legally you can't go under 1.5mm2 but that's mainly anything ac mains in relation to the circuit breakers. Also, legally in most countries, you're not even allowed to wire up your own electronics without a license anyway. Just buy the...

Was thinking the LED advantage of under canopy would be narrow lens' for extra leaf penetration. A lot less wastage than a dude I know who used to put a reflector and hps upside down a well as less dangerous

I'd rather buy a grow tent. But this system is automated. There's not much to do when you know what you're doing anyway.

Hi. Because LED are so damn bright, don't put out much heat etc, I think it's time for someone to try a few under the canopy facing up. I've noticed they are bright enough that you can see through the first leaves it hits. Wonder if there is any photosynthesis efficiency data from the light...

Having read a little bit of this thread, I understand what this guy is trying to say. But with growing as we all know it's impossible to get even light to every single leaf on the plant. Here are some of the reasons "I" wouldn't aim use only 400ppfd. 1. It's not hard to get 800ppfd+ for these...

Not going to happen mate. I'm running a 12 x 18 with 6k watts and regularly hitting 100f+ without an a.c. 20 x 40 litre airpots?? Geezes .. I'm using 10 x 45L air pots with 4wk veg and pretty much fill out 80% off the room leaving little space to walk around (I mainly crawl).

I don't know about your country but the there is 1 live, 1 neutral and one earth here in Australia

Highest Driver DC output voltage / COB forward voltage = Your answer. 305v / 36 = 8.4 So 8 CXB3590's on that driver. Of course, maybe double check or wait for someone to confirm I'm correct before proceeding. The CXB3590s although have a forward voltage of 36v, might 'ACTUALLY' require lower...
