You're confusing the 660nm monos with the PC Red, which are lower efficiency but have a much broader red spectrum as @welight explained above. The PC Red doesn't use Samsung LEDs, it uses Sanan. I also need to point out the obvious that by the time the LED light passes through the diffuser, up...

OK then, let's look at the White and PC Red Buddies. But before I go any futher, anyone who doubts the accuracy of LED Teknik's $80,000 Danish Goniometer should read this first: https://www.visosystems.com/products/labspion-uv-vis-goniometer/ Compare the above goniometer to any of the cheap...

Teknik isn't here to defend himself, but as a distributor of these products and someone who works with Teknik on various horticultural projects, I can address most of these claims. The link you provided explains much of the background of Buddies, but there's a bit more to it. Here is a quote...

I think my point was that it was exactly the same study. The study Bugee refers to in his YouTube video is the same one I linked to but he had different conclusions when pointing out the results. IMO only one conclusion from that study can be right. Spectrum either affects yield or it doesn't...

Unfortunately Bugbee contradicts himself. And not for the first time. Here is the actual peer-reviewed scientific test and you can see Bugbee's name on it: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0248988 What does the abstract say? So you can see that while Bugbee...

Thanks for the study but I can't help thinking that if white light is so effective against mites then why are all LED growers prone to them? Almost every LED grower I know has dealt with mites at some stage or another, LOL! Cloning is a good example as many growers use a high CCT light around...

We believe Bugbee is wrong on this. I have seen the claims but I haven't seen the evidence. I don't think Bugbee has ever produced evidence for this, he only stated it. If I am wrong I would love to see the results so that we can all compare which spectra were being tested. If we took Bugbee's...

Thanks to everyone for the kind words :oops: @grotbags love your spectrum mate! I can answer this. From very early on we discovered that adding far red light accelerated flowering and increased yields. In most cases we saw flowering times reduced by about 10% with the same yield, and in some...

I asked @Prawn Connery to answer this and his short answer was "No". He said he still had to watch out for mites and aphids under UVA. I guess that makes sense as the sun doesn't seem to kill off mites and aphids outdoors but maybe that's because they hide under the leaves. Perhaps it also...

We'd love to hear your results if you can post them up. It may be that UVA "hardens" the plant in preparation for UVB exposure as natural sunlight contains both. We also have to remember that cannabis has been selectively bred under HPS for 30 years or more, and that those genetics may not have...

BUMP! Two weeks to go :rolleyes:

Just a clarification on driver kits outside Australia. Sorry, we can only deliver free shipping for full driver kits to Australia and New Zealand. Our drivers are Australian spec, so the warranty only covers AUS/NZ and the plugs will only fit those countries anyway. If you are outside...

FREE BUDDIES OR FREE INTERNATIONAL SHIPPING! It's the end of the Financial Year in Australia, so for all of June we are offering FREE INTERNATIONAL SHIPPING with any order over A$300 or FREE QUAD BUDDIES KITS (60W side lighting) for all orders over A$800. That's right, up to $200 worth of FREE...

Yes I can't remember the thread and I think it was @Prawn Connery who posted it, but it rings a bell and is the post I was talking about. For "short bursts" they could maybe be for 2-3 hours a day continuous, which is the same as turning the on/off once a day. If we can find someone running...

You may be correct that the best way to utilise UVB is to run it for short periods to stress the plant into producing secondary metabilites, and then turn it off or dim it to prevet those same metabolites from degrading. I still think @Rocket Soul has a good point, because while cannabis...

Hi guys I'm sorry I missed this earlier. @Rocket Soul is correct: the grower has his lights lower and he uses the fluros as supplemental light for longer periods. He thought it better to err on the side of caution with UVB because he figured he could always run them a bit longer if the UVB...

Hi mate, no news yet. I know they are being produced as we speak, but no ETA yet. I'll ask LT again later for you. Off the top of my head the Blue Buddies are going to be a mix of 405nm, 420nm and 480nm. It will be something like 405-420-480-420-405-420-480 etc with 2x420 for each 405 and 480...

Hi mate, yes I know. I'm just trying not to spam (although I think I already have – sorry). All our LED panels feature a small amount of UVA, near-UV and almost 10% Far Red on one channel. You can check out the link below or you are welcome to email or PM me if you'd like to discuss options...

Hey mate, well I didn't post here to sell you a light! But I can tell you the R-Specs have negligible Far Red in them, which is where we believe the real yields and shorter flowering times come in. In that respect I think the COBs you have now fit the bill. Even though they are less efficient...

The problem with the horticultural LED industry is there is a lot of bullshit out there, such as claims that 200W fixtures can replace 1000W of HID etc. We have a lot of experience replacing HPS with LED and I can tell you the secret to HPS yield is threefold: 1. Cannabis has been selectively...
