Is that a black light Gazoo?
Now that is a well set up grow chamber Gazoo! You really pushed the limits! Some awesome adjustment too!
And I love the action figures!
Nice setup, I like the scrogs, I hate putting a bunch of stakes up.
I was thinking of 36"x30" screens, one for each plant. I have shitload of 1" pvc conduit and string.
Nice setup Gazoo.
Gazoo, the blacklight has me curious. What are you testing?
I'm trying to optimise light penetration, see my avatar.So... why have I decided on PCB board lights as being the best for growing?
Efficiency (of course), and penetration. Wait a second...these boards have 304 little 0.3W diodes. People have always said low or mid power diodes don't penetrate! Shiggity must be hitting the Huckleberry Kush rosin again! He's saying that low power diodes penetrate better than the king of penetration the 1000W de hps. He can't be serious right? I am as serious as a catholic school nun baby and this is why!
Penetration is an interesting subject. In the past most people have referred to a single point source of light like an hps being best at "penetration" but the truth is that most photons are blocked by the first layer of leaves they encounter! Think about one of the most efficient grow styles, the scrog. HPS or led no light is getting through that scrog layer if you are doing things right.
So what is penetration defined? I would say it means how much of the % of plant leaves are going to be hit with good light?
The answer is slightly counterintuitive. But makes a lot of sense when you think of it.
Really the more sources of light...the more the emission is spread out the better the penetration of light into the canopy. If we are doing our jobs right the entire canopy will block light that is traveling vertically downward.
The key is that a spread out light source will hit the plants at all different angles increasing penetration of the canopy. Take this example. There is a cola directly underneath an hps. It will get light directly from above. On the sides it will get light that has reflected off the walls. But there will be shadows on that cola. Places that never get good light.
With a cob array that cola will be illuminated from all sides. Much fewer shadows, therefore better penetration.
In the past I have seen people argue that LEDs don't cut it because of lack of penetration. Especially low wattage diodes. But the truth is that a photon is a photon. A single photon won't travel any faster or slower or farther if it is from an hps or from a 0.3W diode. That photon will behave exactly the same as any photon of the same wavelength. So really we need to think of how many total photons are traveling in the direction of the plants.
A perfect light source would be a uniform light "film" that had a completely spread out light emittance. It would throw photons evenly across the whole canopy.
Right now the closest thing to that are quantum style boards. 304 Samsun Lm561c diodes on one rectangular plate. Or sunboards with 240 diodes. Or chilled boards etc. These Samsung based boards all beat hps and cobs because:
1. Light is spread out evenly
2. Efficiency is higher (more photons per watt than any other current method)
3. Emission from many low watt high efficiency sources means the least amount of heat. (I can put my boards less than 12" from canopy and the plants are fine. There are no dark spots and no hot spots because the light emission is so spread out.
We are looking to create the most diffuse emission of the most photons per watt. This creates the most "penetration" and is one of the reasons why high efficiency mid power diode boards are the new best choice for maximum canopy penetration.
I'm trying to optimise light penetration, see my avatar.
I've hung my 600's bare bulbs x 6 ......horizontally.
It's hard for me to see the avatar. Can you upload a pic of the room?
Gazoo, have you seen my current light setup to get uv-a maybe?
I apologize for the quality of these uploads ,I can't fit the whole room into a photo.
Hats a crazy jungle brother. How many days post flip?
EDIT:
Seems I address this to Shiggity when I really needed to address PlantWrestler, I could
change the header but that might mess things up so I will leave it alone.
Original post
Well on the way to Double Canopy Jungle Those 600w bulbs down inside the jungle would
worry me, I see you positioned some heat shielding GOOD idea.
You have a lot of room to supplement but maybe some 4 foot T5 full spectrum fixtures hung
vertical could be less expensive and a lot less heat.
That's 1.86 grams per watt, never seen that kind of results with hps .
