Damn. Gonna have to find some of that action!

How are half you cunts running gg4? Did a clone make it over the pond?

Every time I see this thread title I'm reminded of Ice Cube - Check yourself...

The guy is just a salesman. My Meanwell HLG-600H drivers are managing 95.5% efficiency (tested power consumption myself). "Medical grade drivers"... Lol. He uses every opportunity to bamboozle buyers. People like him a big part of the reason LEDs continue to have a bad rep. He doesn't care as...

I thought he'd probably discounted that as being a pain in the arse too :)

There are 2 issues here. 1. You probably have 1 or 2 hermies. Just a few bananas is all it takes to seed your bud. Particularly if the hermie spills it's pollen around week 3-4. 2. You have seeded bud. This does not mean all your plants were hermies. It just means all your plants were...

Easiest option for dimming with those drivers (IMO) would not be dimming at all. It would be having half COBs on a circuit off the mains with a simple on/off switch, and the other half on another circuit. That way you could switch off half your COBs at a time. You could wire it up so that...

1. Your COBs are 36V. If you run them at 1400mA you get 1.4 * 36 = 50.4W. I think that is the max light you can get out of this combination of driver and COB. 2. SEC goes to the COB. I have no idea about a potentiometer. Maybe someone else knows? 3. Yes 4. Yes to the mains. You can connect...

He's right. There is an extra 12V output on the driver to power a 12V fan. You don't need to use it but it's a nice little extra.

You're right. One is in Tartumaa, Estonia and the other in Tallinn, Estonia. Not being familiar with Estonian geography and knowing Citizen usually only has 1 distributor per country I wrongly assumed they were the same.

You know what everyone would love to see? 80CRI vs 90CRI a shootout! 80 CRI Citizen COBs give around 20% more lumens than your 90 CRI COBs but does that translate to more buds? Nobody really knows (although there have been a few basic tests done by people posting here). Most people are opting...

That is a difficult question because there are so many variables! But I would say that sounds like a good plan. You've already bought the COBs so there's no point discussing that :) At 50w each you will have around the same total wattage and around 20-30% extra light compared to the Gavitas...

The drivers will work. Datasheet here: http://win.tcisaronno.com/Downloads/?IDitem=543&field=docs 90% efficiency is something to consider, but you'd have to spend at least 2-3 times the amount to get a higher efficiency driver. You could have them set to 1.4A which would run the 1212s at...

Genuine blueberry seedlings do this. It is a hallmark caused by their inbreeding. The majority will grow out of the mutant leaf phase into normal plants. Don't worry. Be happy :)

1800w of water cooled COBs in a 8x4 space (have 2 identical tents flip flopping):

I'm getting there slowly... Added another 600w per tent today and did some fiddling with ventilation. Here's a tent in flower mode: And veg mode (I'm only planning on vegging for 1 week max once plants are moved into these tents from the dedicated veg area): I now have 1800w of water...

Your camera is back focusing because it's too close to the plant. Move back 10cm and try again.

Great! Do that :)

The meanwell drivers don't care if you're running 120v or 240v they will work fine either way and auto accept the input voltages. They don't care what plug you put on the end. The issue is safety. You're creating a situation where you could plug in other 120V items into a 240V socket... which...
