LED and BUD QUALITY

[CannaT]

No. But it looks like I can use my account again.

I'm not sure I follow you. You said this:

So what makes you think only LED plants have Ca deficiency? And in what way do plants not "behave naturally" under LED?

Now you're saying you grow fine under LED???

You guys say stuff and then contradict yourselves. How is anyone supposed to follow you?

And of course the sun imparts energy in the form of IR – that's how the earth's surface is almost exclusively warmed. But it doesn't all stay as IR energy for long – it is converted to other forms of heat/energy. Air currents and ocean warming are the obvious ones. Which warm things up which in turn emit their own IR.

You could be sitting in a dark room at night with no visible light at all and still be surrounded by IR.

So what – exactly – is the point you're trying to make?

If adjustments are made and if you know what you are doing, it can be done. I am not contradictory at all. Only you, like an led seller, misunderstand my words. The palm tree cannot live "naturally" in the northern regions. But if you know how to make things that will cover her flaws she will survive. Marketing trolls and salespeople please. To stick to the topic.

Ever since the led bulbs for the grow room came. always looking for some reason to justify them. Calcium and magnesium, raise the temperature, and add IR... it's obvious that they are insufficient by themselves. Only blind people don't understand that. How many growers do I know who have added a couple of hid bulbs to their grow rooms to make it easier to handle things with LEDs.

Growing indoors in the uk I'm tring to create a warm tropical environment like the Caribbean. Not Winter in Russia.

Ha! This is easy with HIDS, unfortunately not so with leds, i have to add so much more with the little bstards it's just not worth it.

Hids for the win. Plug n play...piece of piss alll year round

hid bud smokes waaay better too. Everyone knows that...

I think that Dutch,UK and a like climates
Are best climates for Hid grows in the world...
Mostly cool and wet...perfect for Hids.

If I live in south Spain,Aussie and climates alike Led only or Led + bit of CMH will be my choice.
Hps are too strong for hot climates...

Only thing bad with hids in UK,NL is



That is the one of reason why people chose leds.

Again, I don't follow you. ALL plants need "adjustments" – and every good grower knows it.

"A poor tradesman blames his tools."

You can't grow an indica the same as a sativa – they evolved in different parts of the world. Sativas can handle higher light levels. They are more resistant to botrytis. They prefer slightly more acidic media. They don't need as much calcium or magnesium. They can handle higher temperatures. You need to manage them for longer flowering times. Etc.

A lot of indoor growers simply can't handle sativas indoors because they don't have the patience or skills. Because they don't know how to make the "adjustments". IE, they don't know how to read the plant.

I mean, how could LEDs possibly be "insufficient by themselves" when plenty of people are growing under them without issue?

I don't use IR. I don't supplement with HID. I have no climate control at all. I don't even follow a VPD chart.

And yet . . .

I disagree.

I grew with HIDs for two decades in Australia. Summers here are always in the mid-high 30s and always go above 40C, sometimes for days on end. I wasn't the only one. And I had no aircon and grew in a tin shed out the back.

I also grew with 1200W of HPS in a 4'x4'x6' box! And yielded 3.5lb like clockwork each and every harvest.

No signs of heat stress here:

But back to LED. Here is a guy on his second indoor grow under plain old LEDs. The guy is an absolute noob, and yet he managed to carry his grow all the way to harvest without a brown spot!

I'm so tired of hearing about how hard it is to grow under LED by people who can't adapt.

How the fuck did he do that???

I grew in a sealed tiny cupboard with 400w hps and no air intake and i got a nice yield of running buds.

I much prefer the look to the greasy hps grown buds than the dryer looking led ones in your pics but of-course both lights can grow good weed.

On a side note..

Haven't you got your brand on the side of these units yet

Happy new year everyone. One love

How can you tell? You must have super powers!

What was this grown under?

What was this grown under?

Super powers aside, there are guys growing 30+% THC under LEDs – proven.

Look at these lab tests done under LED. 29% cannabinoids in two different tests.

^ 24.2% THC (THCD9 + THCAx0.877)

^ 24.6 % THC


Everyone has an opinion on LEDs, but very few people bring facts to the table.

 

[Prawn Connery]

I get the inference that I'm just an LED salesman, but there are people on these boards who have known me for 20+ years when I was growing on OG, even before I started dabbling in LEDs.

Hell, 20+ years ago we were talking about CMH being the next big thing (which didn't happen for another 10-15 years and were quickly overshadowed by LED).

I will put my money where my mouth is every time.

Give me a light and I will grow under it. Give me a strain and I will get the best out of it. Show me superior plants grown under HPS with the labs tests to back it up and then we can have a real discussion.

Until then, most of what I see is opinion.

Hmmmmm.

From the lack of visible resin... i'd take a stab in the dark at leds?

I know you been around for decades.

Top one was HPS. Bottom one was LED.

EDIT: I threw a sativa in the top grown under HPS to compare to an indica grown under LED to prove its more strain specific than lighting, IMO.

Here is a LED bud with a close-up of its resin. This smokes – and more importantly tastes – as good (or better) than anything I grew under HPS.

 

[exoticrobotic]

I may have another go with leds at some point but in my cold room they just dont do as well as hids.

I know. And I'm not trying to be a dick. I get labelled a troll because I "troll for truth" (to pinch someone else's motto) when I'm just passionate about the subject. I know a lot about LEDs and I've heard a life-times worth of "bro science". I am simply trying to dispel myths. I am not saying my way is the only way, only that people should make decisions armed with the best knowledge they have at the time.

So yes, I design LEDs. I don't own Grow Lights Australia but I am affiliated with it – I've always been transparent about that.

But the elephant in the room is, why would someone (like me) who grew successfully under HPS for 20+ years suddenly switch to LED with no desire to go back if I was getting poorer results?

It's something very few HPS growers can answer. Why is everyone switching to LED – even experienced HID growers? Why do so few of them switch back?

I'm not here to convince anyone. Grow what you want to grow. But at least make an effort to understand the facts before you start.

That's not aimed at you mate. And don't worry, I have a thick skin (shell). But I do like to joust!

^ OG used to have a jousting smilie

I may have another go with leds at some point but in my cold room they just dont do as well as hids.

Grab a 3100K CMH for the IR, UVA and violet and then grab a decent 3000K LED for the red balance and efficiency. I got a lot of guys started on LED by mixing CMH and LED to begin with. Most of them still keep a CMH bulb lying around to provide warmth in winter. I still advise people not to throw out their HIDs when they buy LEDs just in case they need to warm their grow room.

Maybe that sounds like I'm contradicting myself, but if a HID can provide metabolic warmth and light at the same time, then use it. Use whatever works.

I did try this combo, the yield was smaller than just leds alone but the quality was way up with the led/cmh combo.

I'm sure leds have come a long way since i tried them but the units i tried are still currently for sale in growshops.

Maybe better units will become available with leds (one that has a bolt on cmh in the middle )

That second bud in the 'guess the light used' post is massive, what led unit was used for that grow and what was the strain?

Great to see some detailed honest and open discussions.

I start to talk about light quality you start to talk how I grow...wtf man ?
I have no problems my led plants are good and hids plants 2.

Stay on topic.

Yep u are right depends of setup you have.
If not ac cooled room,only air cooled room 40C outside and have great buds under hps...I will like to know how to do this magic trick.

I dont know but you start sound bit funny.
For some grower with such expirence.

 

[CannaT]

Some led only grown BruceB..
Fregnant,rock hard...no brown patches...same soil same nutes like this my hps/led grown bud.

 

[maryjaneismyfre]

Easy way to fix the not enough heat problem....throw in more light!

 

[CannaT]

BruceB led/hid grown.
