New light or????

[Olive Drab Green]

I can tell you this, I don't imagine being able to grow the size of trees you have pictured above with my EB panels. The intensity drops off fast, the lower branches will not receive the saturation of light any where near what the tops will. Could it be done? Sure, but at what point is the even spread not worth the loss of penetration.

Ive found, in order to generate the type of penetration that would be required, to get those lowers that thick, on plants that height, the strips need to be packed together to such a point where it is nearly counterproductive to do so.

To get 20,000 LUX at 36", I had to put 15x 2ft' EB gen1, at 700ma in a 30"x30" box....
Strips are IDEAL for scrog type training, limited height situations, but Id have to say COB would be the better choice for "tree" grows....

I definitely think that the intensity in an 18x18 put out by a single harder-driven COB is the cause or greatest contributor to having such great lower bud production. This is an opinion based on personal observation, but this is what it appears to be for me.

This was 241w of COB in a 4x2. 4-foot tall plants. Strains were HSO Lemon Garlic OG on the left, RiddleM3’s Colorado Thunder Fuck on the right. Can you show me something similar?View attachment 4086439View attachment 4086440View attachment 4086441View attachment 4086442View attachment 4086443View attachment 4086445View attachment 4086446View attachment 4086467

250W of Samsung strips Yielded over 9 ounces - after bud rot losses. 2x4 foot space. Roughly three feet tall. I didn't grow it tall, because I didn't need to grow it tall to get a good yield. Height is not relevant to yield.

Just under 3 feet tall, been in flower for almost three weeks, I'll be trimming her this weekend.

Still less than what I did with 241, by a bit. I was also running two plants. You can see the Samsung strips don’t penetrate well, comparatively. That said, very nice. Beautiful plant. I’m actually pretty impressed, for what my opinion is worth.

Honestly, I don't think a valid comparison can even be made. Growing different strains (even different phenos) changes the equation entirely.

Not really comparing quite like that. I’m just saying, you can tell the EBs lack in penetration, intensity-wise. Still, I’m pretty impressed with the EBs at 250w. Maybe I’ll at least expand with them.

 

[Olive Drab Green]

I think using the COBs in conjunction with the EBs would be perfect. COB for the core, then EBs along the sides. Maybe I’ll just add another driver to my frame, daisy chain the setups together, and run the EBs modularly as I see fit.

Two factors to consider - one, significant losses to bud rot as I had to chop off 4-5 decent sized colas. Two, these are not even the high efficient Samsung F series strips at 180 lm/w, these are closer to 120 lm/w efficient. With Samsung F-strips I could drop my wattage to 180 or so and still have the same amount of light - OR run them at the same wattage and raise then up some to get a deeper "sweet spot" Either way adds up to more yield per watt.

Oh, dude. I wasn’t even patronizing. Great work. I’m legitimately sorry about being a dick before, by the way. I’ll have to look into the F strips.

No prob, I didn't think that at all. Just wanted to point out what's holding me back from even better yields. I'm actually looking to pick up some better strips here soon for the other side of the cabinet (its another 2x4 foot space) and I'll retire the $2 Ebay cobs running in there.

What nutes do you prefer? I run Roots Organics. And what strains are you running? What I have right now is SR-71 PK x Sour Diesel, and a pure Sour Diesel.

I've been doing good with just GH Maxibloom and CalMag (Lucas formula) from start to finish. I found using the Maxigro seemed to cause N-tox every few weeks. Haven't seen that since I stopped using it. Last few plants have been Plushberry (that first pic was the last plushberry clone I had), the one in there now is a Harly Tsu. I've also got a bunch of Black Gorilla seeds a guy gave me that I'm going to start soon.

Have you ever thought about organics? Like, I dunno how long you’ve been growing, but if you haven’t ever tried it, I have really fallen in love with Roots, personally. Organics are self-buffering, pH is less important, and it’s not as easy to overfeed with.

Well, I figure if its not broke don't fix it - the GH nutes seems to work well in my setup. A $12 bag lasts me a year, so its affordable.

Ah, yeah, certainly. I just meant if you ever get bored and feel like experimenting and branching out.

If I ever get around to expanding my grow area, I may experiment a little more.

Are you still curious about some F-strip results then check this out.
The thread is from a very gifted member who works with stripes for the first time. Imagine what he can do once he has gained more experience with strips ...

This is just one cola of many and as you can see, nice and hard buds down to the very bottom.

Strips indeed have a better "penetration" because the light from hundreds of diodes hits the plant from thousands of angles, so you barely see any shadows in the upper half of the canopy.
The more light sources there are, the more diffuse the light becomes and the deeper it can "penetrate". With one or even with three light sources, you have much more shadows and the light is reflected much earlier, with stripes always a few light rays make it "under" the canopy because of many different angles.

I definitely am interested in the F series to expand my COB setup.

The small and more varied the light sources, the less penetration. The reason COBs penetrate better is because one massive emitter face concentrates all of the light into a massive beam which, by virtue of its intensity, can penetrate into the lower nodes and allow for proper internal circulation. Those multiple diodes spreading out the light is the reason regular panel LEDs can’t compare to COBs regarding penetration (besides cheap knockoff parts and underpowered current.) It’s the same reason you stack strips tightly against each other: To concentrate more light for better penetration.

That said, beautiful cola.

 

[Olive Drab Green]

I dunno if you realize, but light hitting the leaves draws moisture, nutrients, and respiration up through the root zone, up into the plant’s stem and branches, and it brings that pressure of metabolism, hydration, and respiration through the leaves. The plant’s almost like a solar-powered wick or straw. If you can give adequate light intensity, it’s like sucking the straw harder, rather than just spreading it out over the canopy, that increases the metabolism and respiration throughout the plant.

This is totally wrong, buddy!
It seems you do not understand how penetration really works.
At first, penetration is a myth!
When intense light falls on a leaf, the exiting light on the other side is green and has lost most of its intensity. Also, the light that is reflected from the leaves and so penetrates deeper is mainly green light.
All areas that lie in the shade of the canopy, get no direct light.

Please google "Benefits of Diffused Light".
I'm sure after a few articles you know that only diffused light is able to penetrate the canopy. Consider why greenhouses are made of diffused plastics and not of clear plastic. Diffused light harvests up to 12% more, due to better penetration.

People have been switching away from panel LEDs to COBs because the varied light sources couldn’t penetrate for shit. Like I said, it’s why you have to stack strips: better concentration for better intensity.
