No email adress, mate! Sorry! But feel free to ask what you want. You can also leave me a message on my profile page. I can send you a pm as well and you only have to answer to start a conversation.
It does not take long before all functions are released. It goes faster the more likes you get...

There is no special reason for the 5 and 10% recommendations. Only 5% far-red because too much will increase the stretch and you get longer internodes but you can use also 10% if you like that.
I will add a pdf below where they tested with and without far-red and they used up to 90μMol/s/m² additional far-red.
And the 10% deep-red I've recommended because colored top bin diodes are f*** expensive. If you want the efficiency level you see in the datasheets you need to drive them low(350mA). That's only 0,735w per diode. You need ~40pcs deep-red diodes to get ~30w deepred with ~57-58% efficiency. That's at least 120 bucks and you need a driver too.

I've added the 8 Bridgelux V18 COB's because they are 3000°k/CRI90. They run with ~500mA(17w) and are driven by an HLG-120H-C500B. F-strips are only available in CRI80 and I want a mix of both to get a wider red spectrum and a bit more far-red.
The far-red trigger has only 6 Cree XP-E diodes but when the stretch is done I let them run all day long with the mainlight and switch them off 5 mins after the main lights switched off. This way the plants gets a bit more far-red and this seems to have positive effects(more efficient photosynthesis, faster maturing, shorter flower cycle).
The main difference between CRI80 and CRI90 white is the red shift and the increased far red part(twice as much). Far red itself does not much on photosynthesis itself but it seems to have beneficial effects compared against plants grown under colored or CRI80 white LED's(with almost no far-red).

A few well known members here use strictly CRI90 since they made a side by side test with CRI80.
@The Dawg for example has a few interesting threads showing impressive differences compared to CRI80. But be warned! You will feel small and miserable with your own skills when you see his results, lol! At least you're not alone...

I run a constant setup with mothers and clones. All stages running all the time. I put about 3 to 6 in at a time to flower. Veg is under t5s at least 4 to 8 weeks. I like large scrog plants. Oceans forest, promix, and added perlite. Also run pure organic. Only guanos and castings. Lights are cheap Chinese bull shit but they work great...4 x 1000watts Same as expensive ones I'd say at a 1/3 the price. Amazon 120 bucks.

Glad everything is working well for you. I have a perpetual grow started myself under what I consider entry level COB Units. $128.00 a piece About 300w each from the wall. They are full spectrum white and plants are loving them. My main plant that just got flipped damn near filled out a 6'x5' foot scrog net. Hoping she flowers well under them.

A good example how one can persuade themself, lol!
I promise you that a 135w quantum board kit will blow one of your 1000w lamps out of the water. 2.55 μmol/J (W) vs. 1.3μmol / J means that it generates twice as much light per watt.
Okay, you need 200 bucks for a kit but therefor the boards are made by Samsung using only the best binnings available and not in some backyard garage in shenzhen and crappy Epistar diodes.
They grow indeed some nice weed but you can not compare them. There is no way to get near to 2g/w; in the best case a good grower can get 1-1,2g/w with such lights. That's a fact!

Just curious.
Does it hurt my feelings lol.
Are you trying to hurt feelings?
I just figure someone who finds there way to the LED section and mentions haters probably has a history.
You don't sound like a nice newbie, More like someone with a chip on there shoulder.
You gonna share some love on RIU?
Feel like sharing your history on forums or are you a child planning on hurting my feelings some more?

Yeah, I've already seen the new light in your grow journal. They work even if not that efficient. Entry level COB's is a good term for them and if one knows what he can expect from such lights nothing speaks against them. I just find it's funny when I read they are just as good as qboards. If so, we would all use $ 90 blurple lights from Amazon...

I've a few of these full spectrum COB's myself, 50watters driven below 5w(140mA), 50:50 mix with coolwhite and supplemented by a few red and deep red 10w COB's running at ~1,5w(240mA), only 56w at the wall and a 3ft² area.
It's for germination and early vegging and looks pinkish white. Seedlings seems to love it and stay short enough..

Have currently 5 seeds under them; 4 have already done it, one is still missing. But he(she) should also see the light of the world unlill tomorrow.
Two are my own. A BlueDream hermied last run and has caused a few seeds in the plants next to her(only 12 and 21 sseds), one was an Amnesia and the other plant a GreenPoison. First seeds grown with additional UVB light, lol!
Just germinated them for curiosity. As long as the hermie genes stay hidden it's all good; if not I'll throw them away.
Press me the thumbs, mate. By chance many keepers have already appeared..

No i just dpnt give a fuck. And i dont have a chip i simply am apathetic. And blurple lights always cause a bit o static when you mention you have run them. That good enough for ya local hero.

Just came home from shopping and checked the seedlings; the 5th one is already breaking through the soil. A few hours and he is done.

Glad to hear it Bro. Threw my damn knee out yesterday. Bitzy was watered early this morning. Since clones and lights are in the other room now. Not gonna do shit but lay around and that's all. Wish I didn't throw it out though. Because I do have to stand on a chair tomorrow or next day while the wife holds onto me and take the lights down over the scrog and put that other 2"X4" up on the pivot bolt. Then reattach the lights to that board for my manual light mover so I can turn it once a day during the light cycle. Like I said, not attempting it til tomorrow. Keep your fingers crossed and say a green prayer that I don't fall through the scrog. That would just be awful...

Lol, maybe better you let yourself fall on your wife when ...
To work under the ceiling is always a PITA. Be careful, bro!

Current top bin LED's beat HPS easily by around 20% and more. An example, Osram Square series diodes in deepred reach up to 3,9μMol/J(watt), a 315w CMH is 2,1μMol/J, a DE HPS has ~1,9 and standard HPS have even lower efficiency. Current Quantumboard v2 has for instance ~2,5μMol/J efficiency and 4 of them with an HLG-480 driver(500-550w max.) are used to replace 1000w HPS with no loss in final yield.
There are lots of vids on youtube(GML show, ...), mate, and here are a lot of qboard related threads.
I would suggest you look at a few...

Thanks for taking the time to respond. I'm swamped By the amount of info at the minute. I could really just use someone to point me the right direction of a good Cob set up I can buy in the UK? I am.planning on doing a small.grow in a 1.5 x 1.5 x 2.0 tent. May only use half the space for the plants (a scrog) and the rest for equipment. I have contacted timbergrowlights which will deliver to UK but you have to go to the customs depot to pay the customs charge so they will open and look at the contents so I'd rather not get it shipped into the country. Although I see their lights get great reviews and will just go for it if there no decent alternative here ? Shipping from them is an extra 100 dollars and the customs fee (which I am unsure of the amount but Dan at timber assures me it's not too much) was looking at something to do veg and bloom and cover roughly 2ft x 2ft.

You might want to try one of these for that space. I bought one because of a disability budget, then bought a 2nd one a month later. They are full spectrum white with a great footprint. Pay no attention to the 1800w. They are around 300w from the wall. If you want to see what they can do, check out my current grow log. Not 1st Grow, But 1st LED Grow. Below is a current canopy shot of one plant in a 6'x5' foot scrog. Had 2 plants under them but 1 male on me.

diyled.co.uk but he concentrates on Quantum boards and strip builds rather than COBs.

If you really want cobs best to make your own in these parts. It would be fairly cheap to do for 2x2ft.

But I would just rock this in a 2x2

If you try COB, Cree&Osram chips are best, I tried other chips, but heat dissipation is a problem. After I tried Mars COB, I am satisfied with it,but it is small, not very cost -effective for large growing size. If growing 1-2 plants, it will work.

DIYLED UK has similar good COB fixtures like Timber. Contact him via pm @diyled he's member of this forum.
You can also get H-influx strip or Quantumboard based kits both with latest Samsung LM301b. In your situation probably the best you can do. I believe shipping is free within the UK.
