Calling out to Weezard for LED advice

[Bubbleblower]

It seems what I am looking for is a so called led droplight (or stem or canopylight). When I google that I get the same products from the same manufacturer every time again.

Is that any good?
Are there better non-diy alternatives?

The x-mas tree light design looks like it would take up a lot of space and wouldn't spread the light evenly and the net design would have to be hung vertically, because otherwise it gets too much in the way.
So I could only hang about 4 or 5 of these per m2, while

Percentages of IC lighting generally varies from 25 to 50% of the total light.

so I need 4 times that.

Nets like these that are less wide (deep) and have about 30 or 40 watts in power would be just perfect.
Especially if you could have the spectrum custommade.

Searched some more for intracanopy light, but no one seems to call it that.

I did find flexible strip lights, led ribbons, ropes and strings, light rings, decoration and advertising strips, led softlight and dura flex or even curtain and x-mas lights.
Now I realise I always had one of these strips in my garden and from that I know the thick PVC type strings are no good -too heavy and too big-.

It will take a lot of time untill I can see the trees through the woods, especially since all this stuff seems to be for sale in China only.
Chinese companies usually don't give the information that is vital for your decision.
Isn't there any hydroponics store selling intracanopy lighting yet? (the ones I found seem to be out of bussiness).
To me it seems easy to design and it has many proven benefits.

That's what I call a "clue".

No wanna burst no bubbles, brah, but da only "proven" benefit is the ease of design.
Though they do come in handy 'roun' Christmas time.

Sorry 'bout dis.

All kidding aside,
Dey have been well, and thoroughly tried.
An' when dey post da yield report,
Droplight grows?
Dey come up short.

Suggest you buy a UFO fo' da veg. grow.
That, will give you time find a decent bloom light.

'course you CAN bloom under a UFO.
(I've read that, have not tried it personally.)
I did personally futz with droplights in 2007.
Wasted a couple months.

Just FYI.:beatdeadhorse:

May be I wasn't clear
but I already have some blooming lights here.

According to Purdue University
you want some extra light under your canopy.
At least 25% they recommend
to get a dense and healthy plant.

So I wil get
a special net
but I need to find
the proper kind.

I wish you well,
you could be right.
The plants will tell,
What's enough light.

But, once you find the proper LED,
Be a pal and start a thread.

Da weeze will lurk there-in.

He custom made me my LED lights. WAYYYY less than buying them from anyone else. Three year warranty. Very nice to work with.

I vegged under my all blue one. It worked well but had some stretch as the blue lights don't put out as many lumens.

I'm vegging under my red/blue 120W right now and the plants are MUCH tighter. $180 bucks shipped for a custom 120W LED light. Can't beat that!

May I ask what the finished height of that one was? and what do you ususally finish at? It does not look like it lacked for light down low, that's for sure.

Sorry not to answer ya, I got sidelined by some medical problems. Guess ya saw the measuring tape by now, those plants finished around 24". They had vegged to 20" before I was able to flip them.

I would have preferred to flip them at 15-18". At that height I can easily hold them to an inch or two of stretch simply by cranking up the blues and cranking down the reds until they settled down. Finishing at 20" or less worked well for this strain and my current setup, and 3 gal. pots gave them plenty of toe-room.

But flipping them at 20" made it harder to hold them back with the light color manipulation. 24" was as short as I could keep them, (but I didn't use Bushmaster or other "non-photonic interventions").

I'm wrestling now with some I flipped at 24" and I can't seem to hold them any smaller than 36-38". At that size they need to be in 5 gal pots, which is a pain. Seems like the bigger they are when I flip 'em, the more determined they are to try to become big-ass plants. Of course, this is just my experience with two strains, in dirt, under these lights.

But, you are correct, sir, I got good light penetration all the way down the 24-inchers, and the 3+ footers are doing okay, as well. I do subscribe to your philosophy of producing just usable bud, not lettuce and lumber. And 5-gal pots fulla wet soil are heavy, and my space is kinda tight so it's a drag for my sick old self to jockey them around to feed and maintain. Ankle-biters are preferable. And next time, coco, if not bubba-ponics.

My motto: "Shoot low, Sheriff-- I'm ridin' a Shetland!"

Best, Hermie

Weez,

I just got my meter in today. To be sure it was apples to apples I ordered the same one you have. 30 bucks shipped from Hong Kong.

It looks like my 120W light is just slightly weaker than yours. At 12" from the center of the light my meter is reading 1012. The beam angle on these 1W must be very narrow as when I go just slightly outside of the glass on the the light the intensity drops off significantly.

Nonetheless, the red/blue light is growing much better plants than just my all blue one. Remember I have the two different wavelengths of blue in my red/blue light as well.

This batch is MUCH MUCH more bushier with much less stretch. Most likely due to the increased light output from the red led's.

Just thought I would give you an update on my china lights. The 120W light only increases ambient temps by 3-4 degrees. Gotta love it!

Maybe one of these days I'll up the ante and build a 15W LED light like you have but for now this will do. How are things for you down in Hawaii?

That's lesson #1. Ya need at least 2 different colors for a healthy grow.

Remember I have the two different wavelengths of blue in my red/blue light as well.

I think you'll find that it's the blue that produces shorter internodes.
I have to turn my reds down to control that 7th inning stretch.
3:10 = Tall.
3:7 = Not so tall

No need now.
All you need now is patience.

How are things for you down in Hawaii?

No wanna gloat, but every time I say, "It just can not get any better than this", it does!

Best end-game ever!:thumbsup:

In this 120W light I went with 100 red and 19 blue. Seems to be doing the trick.

I had two plants that for some reason have wild PH problems. Stretched a bunch and have PH problem signs all over. They were a good 3-4" taller than the others. I pulled them today as I feel correcting the problem and keeping them a reasonable size will be a tougher task than I'm willing to take on.

Well, at least I have an all blue light that I can turn on in flower if they start getting out of control!
