New german strip

[oldbeancounter]

im in the u.s. my buddy received our order delivered to his house in about ten days after payment was made. They had the package out the door for delivery within 24 hours of receiving payment.

Wow, that is a good thing.
Do you know what he bought and built ?
I always like to here real grower report how did this chip work kinda thing as I like to learn
how to one day grow whatever I decide best for myself and cut out roundup, pesticides, heavy metals etc from my diet in addition to "tomatoes" both kinds! lol

He ordered a bunch of osram square 660, and the osram 730. I actually split that order with him. He went with some samsung f seriees strips. He has not gotten around to putting it together. Work, family, etc. but should have some results in about 4 months.
I'm going with the strips from led-tech. With 660,630,730. I plan on experimenting with heavy red.
Also waiting on the brigeleux gen 3 , 90cri for a different small closet size space.
I have a few weeks before i will have everything put together.

@Warpedpassage
Is the thought higher you get into the red's like the Osram 730 does that cast more infa red heat to heat up leaves any idea or perhaps someone reading knows?
brigeleux gen 3, yes I heard they are coming
Any firm dates and from who ?
Costs? Once I get everything and all the stuff at least laid out I will try and take some pics
I have so much stuff to assemble might be months too before i am ready lol

Thats great! Im planning something similar. Except one less 730nm per sq ft, but adding 2 630nm per sq ft. What do u think is the ideal distance between the top of canopy and the 660nm diodes, 6 per sq ft, 1.5 watts per? Im wondering how far the reds have to be under those parameters to not cause the plant stress.

My red and far red leds are at the same level tan main lights.. I think that they will not cause any stress...blue light and uva/uvb are much more stressing to plants

90 is f-in awesome. 70 aswell.

G/w: i feel its its less relevant these days. Our 2/w was on a 11 week amnesia, they get almost 50% more light than a 8 weeks strain.
But then again, we light starve the plants during 3 week stretch to minimise stretch in order to get the plant/budstructure we want. So in the end its its only 8 weeks of flower intensity and 3 weeks at around 12000lux. How do you factor in these things in g/w??

Also theres a tendency for g/square foot to go down as g/w goes up: lower total yield allthough higher G/w.

Arcadias: nice link, the largest one seems reasonably cost efficient. The smaller, 60€ for 24w, damn uvb leds is almost cheaper.

Yes.. I agree with you.. in the early days..all people used a HPS 400 over 1 square meter, same potency all flower period...it was easyto use gr/watt but now…..with all the posibilities...Also is not the same a gr of a 15% thc strain that a gr of a 25 % thc plant. When I get nice numbers I also starve plants at stretching time...cause with high ppfd, high temps and CO2.. plants become gigants in few days… aRight now I flower at 10/14 and far red EOD.. which also adds a new variable... I prefer to talk about total weight per área and time used to achieve it cause as you cleverly pointed gr/watt has not very much sense these days. And for most Little growers space is really the limiting factor.

@nachooo
Do you know if any any infrared head is emitted by either of the red diodes ?(more likely far red but still not into infra red 800 nm I read is it's nm spectrum)

it is odd there is not more targeted sales for LED white light users when it comes to heating up leaf surface.
I have read many others are having same issue compared to HID or CMH which is really their only advantage over LED, that being red above the far red spectrum in form of IR which is around 800 nm I believe I read.

Looks like you used the German slider red chip and glued is that what I see?
I think you did great job, can't buy a light that is a good as yours in my opinion for that size area.

I think the red and far red do not emit very much heat...well if you put your finger on right on it you feel hot...but is not infrared heat.
You can avoid the issue of lack of infrared heat raising temps a Little and following a VPD chart like a religión...
I am using far red with main lights all day cause it happens in nature and for Emerson effect..also my samsungs are 80 cri..if they were 90 cri I would use less far red.
also I read somewhere that far red is used by plant to check humidity air content...just a theory and maybe more far red helps with the transpiration problem that aparently creates the lack of infrared heat. I think everybody is confusing thinking that plants under led needs more magnesium abut actually is a transpiration problem.. Randomblame knows more of this tan me...
but if you really need a good source of nice infrared heat..I think this is the best and is cheap : https://www.arcadiareptile.com/heat-projector/
Yes I bought the slider German red and far red leds..cause I am tired of soldering and I am so bad doing it… the slider is aluminium and acts also as a heatsink if you dont run very hard the leds althought they are glued to a big aluminium strip...

Bridgelux availability can be weeks to months. It seems to me we all started to take supplementing “white” diodes more seriously very recently. Very few people have multiple grows with different ratios under their belt to be giving any concrete advice. If you were asking these questions a year or two from now, i think we would find more members willing to give advice they feel more confident about.

Anyone know if having two extractor fans in one grow room will lower the temp without cause me any problems it's the only option I have?

 

[oldbeancounter]

not good use of power, if you had one bigger is better, they both must go outside or your wasting your time you will just suck hot-stinky-humid air right back in...are you not able to ditch smaller one ? inline fan near exhaust maybe ?

Good to know
Let's face it, after the Nasa light scare it made this tech not be adopted as quickly as it might, but what if "it" used high end LED Cree or Olson diodes in that pinkish purple in that metal doorstoper HGL instead for those Edison's ?

 

[Buna]

Yeah inline is next to exhaust due to shape of room and I'm trying to be stealth

I dont think you are going to find very many hardliners aginst the spectrum hgl is offering. Its a whole lot of other drama and as mentioned by others the cheap components in their build.

Oh I read some then got tired of it HGL drama but what it does say is that individually targeted didoes of light colour you seek in LED might have a competing or better spectrum than "full spectrum white" there is no such thing in my eyes only leaning towards red or blue etc . try 4000k the try 3000k to veg see what happens same diode , maybe was anomaly for me but doubt it, learned a few things growing up on a farm but of course stuff grew outside not inside so thats why I am here to learn how to mimic that spectrum, the one cannabis spent 100,000's of years adapting to or maybe millions of years ,not one Samsung decides is good to market next year to keep R and D going through profits.
