Can anyone help me out here? Should I use the CXB 3070 or the CXB 3590 for double the price, is it really worth that big of an investment? I'm only utilising a 4x4 space, i figured 12 CXB 3070 would work well enough. Are the extra 2500 lumens worth it @ £45 per COB? The 3070 is only £25...

Is it worth the extra investment for a 4x4? I was planning on building 3 (4) CreeCXB3070's

probably due to stock, they have alot of them my only question is should i buy them pre-wired or build my own. timber has them but they're a bit pricey... would be about half the price if i used the 3070's instead of the 3590's. Is there much of a difference between them, just an extra 3k...

including shipping rates too... @Airwalker16 said the price is good.. why the contradiction? who's cutter?

In the video, you used the CXB 3070's If you were able to use the 3590's... would you? Is there much of a difference in yield/quality etc. If I were using 12 3590's in my 4x4 would that be "too efficient" i.e heat problems etc. I guess I'd have to buy my cob's from mouser in the uk, right? I...

The cree cxb 3070's are out of stock (listed in your desc), are they the most efficient COB's? I've been looking on alibaba and you can get good quality cob's relatively cheap, $10-15 each, would they be just as effective...

I'll be using a 4x4, how is a 200w cob unit going to cover that?

@REALSTYLES Thanks for the reply in my other thread, think I'm going to go the DIY route. What would I need for a 4x4 grow tent? I've been watching GrowMau5 and Greengene on youtube, and they don't say exactly what they bought for that specific build. Can you offer me any advice?

And these re-branded ones aren't?

Would these work well? --- http://ledpanellight.en.alibaba.com/product/60167367844-800958797/spider_16_full_spectrum_special_add_to_6500k_white_colour_light_900_watt_led_grow_light.html @Atulip I would build my own, but if someone else already has the exact thing I need pre-built, I'd...

I've got a budget of $600< - These lights are the cheapest I could find that were pre-built. Building my own wouldn't be a problem, need a link to a place where I can buy everything, its all hush hush

Should I be looking to build my own COB's or can I get away with using these pre-built LEDs, Would 2 of these work efficiently? - http://www.ebay.com/itm/Mars-Hydro-600-Led-Grow-Light-Full-Spectrum-Lamp-292W-For-Veg-Flower-Hydro-Panel-/281526869368?hash=item418c4f1d78:g:wwsAAOSwZetXO-dJ

Soo... What did you mean by it?

So what was your point? A hindered harvest comes with lack of knowledge. Looking to improve my overall yield with more plants and equipment isn't going to produce less.... Think you've smoked yourself stupid bud.

Haha, if you say so... In this business I don't think there is such thing as being too greedy Unless you're growing for personal use and even then... most people need to recoup their losses on equiptment.

I could settle for that. But why would I, knowing theres a huge market down here

Why not 40k in a year instead? :???: Sounds more inticing to me lol

I'm still undecided...

Yeah, I get what you mean. I've been given an addy to a manufacturer in china. I can get all the kit needed to build the cobs for around >£500. That's for a 5x5 too. Retailers charge a hell of alot more, that £2k is pure retail. 25 x 120 Diameter Passive Heatsinks @ $6 each = $150 25 x...
