So is part of the problem with some of these COB lights that they don’t have the lenses that say the Optic 1 version does?

lenses will change light focus most definitely! But in general you want to start lower on light intensity with Autos vs Photos. It is better to ramp UP intensity, vs have even 2 days of overly intense lighting. Lamp distance is huge. But whenever possible a n LED with adjustable power is ideal. My light bars are crazy intense! They create wall to wall light! Lamp distance should be minimum of 18-24 inches for full power. If you run full power at 12 inches, you will have issues. Turning it down to 50% will allow for 12inch distance. Without adjustable power, the plant would turn yellow and do horrible yield wise. The same plant with more space would flourish! If you try too much, plants will respond. But some people can mistake their LIGHTING intensity symptoms to a NUTRIENT issue. Because they can mimic each other, and some people Assume Low Watts can't cause stress. As I said. Start low, ramp up slowly ..Not having to turn down due to stress ever! Respect the plant more than anything. She will give you signs. Pale growth of saggy leaves can be overwaterring...or light stress. Raise lights and reduce power of you see pale saggy growth, plants will respond to overly intense lights quickly. Lights are brighter than we realize. If you see a light claiming very high watts, it is prob lower quality. Certain lights do better staggering plants, vs directly over plants. Cobs run that way. Looking like the best buds are in the shade vs under the plant directly at times. @gringuito98 points this same fact out! Overlapping is not good and creates not spots. Added height helps with certain lights. That is why 2x4x5 tents and Cobs are not ideal for full sized plants. Not tall enough for the lights. Peace, slow

Obviously you dont have much experience with COBS, or many other types of LEDs. Three Autocobs running 55 watts each in a 2x4 is not needed and you will have better results with 2 COBs vs 3. Watts is not what matters. Light intensity from Cobs is directed like a spotlight. You need height with Cobs to avoid the spotlight effect. Many times the nicest buds are in the "shade" when using cobs. Also, you have to look at the SHAPE of the area to be light up. Overlapping lights can cause hot spots or cold spots. I have personally used 50+ Cobs for years now to grow.
Now the other thing is TRUE WATTS vs advertised watts. If you go buy an AMAZON off brand claiming 1500 Watts, it would be wise to know that is false advertising and wont put out a fraction of that. With Autoflowering strains and Cobs running 55 watts each, 3 Cobs in a 2x4 tent will cause light stress eventually as the plants get closer to the lights. If you have a 4x4 tent, 5 Cobs is the Max needed for a 4x4 tent. Csn you try to use 3 in a 2x4? Sure it can work for veg, if the lights have enough distance. But ideal lamp distance for Cobs is 2 to 3 ft away from the top.of the plants. Most 2x4 tents are shorter than normal, many being 5ft tall. This is a key factor, as a Gorillia tent with 8ft of height would have the ability to raise the lights an extra 2 to 3 ft. In which case, you might get away without having light stress issues. Moral of the story, dont look at WATTS as your way to light up a space. Look at the shape, height, and type of lights u are using. I have a 6 light strip Samsung light it is perectly shapped and sized for a 2x4 tent. It adjusts to 185 watts MAX. The lighting is wall to wall and even as can be. Lamp distance matters a ton. If my plants are 12 inches away from tbe light, 185 Watts would be too much...and lowering the intensity would be a requirement to avoid light stress. Turning the light down to 50% or Approx 90 Watts would allow you to keep the light 12 inches away without stress. But ramp it up to 100% and that plant will turn yellow and sad within 2 days. Read your plants more than anything. Dont ASSUME lights WATTS are a safety measure or valid number to trust when choosing a light for a perticular space. The same light in a 9sqft SQUARE Tent will not light up a 2x4 tent the same, especially if at different heights. That is why you are seeing different light shapes these days, tailoring the shape of the ligjt to suit the shape of the tents. Good luck, read your plants and dont assume MORE is always better. Peace, slow

I have a 4x4 and run a diy rig of 5xCree CXB3590 chips running @ 250w total.. 50w each. The light is 42" above the surface of my pots and my plants grow into the light. That's the seeetspot for my setup...they're not stretchy or too squat. As things move deeper into flower, I add an Autocob here and there to increase intensity within select spots in the canopy. My lower nugs are almost always rock hard and among the tastiest.

I love my COBs.

5 in a 4x4 is the g spot at 50 watts per Cob 4 sho! You need that height as you also point out. Cobs rock, but in a 2x4x5 you cannot run 3. There is not enough room height wise. I would rather run them higher and avoid the spotlight effect. I like to split my plants, where the center of the lights are between the plants when possible. When you run Cobs you get used to the plants love to grow with the lights higher than one would think. They don't stretch much at far distances. And like you said, the density is really good low on plants. Love my Cobs too! Peace, slow

Ok, here’s the current state of affairs... I now have a squatter in the 2x4... a refugee from my 5x5... it’s a White Crack x Double Grape think it’s about 53 days ( would have to look back to be certain)

 

[R_HIDIA]

Obviously not ideal but it really helped the situation in my 5x5

Day 36
Things are looking fine in the tent, but I can’t help but feel like I’m putting the vigor and gusto of this strain on the shelf a bit... aside from the crowding, I’m having to deal with low temps as well. With the WC x DG in there having a full 2 weeks of flower head start, I had to be wary of the humidity. Without the extraction on I had temps between 23-25C but the humidity got up to the mid 70’s. So even with my inline fan dialed all the way down temps fall to 17-18C and humidity drops to 50%. Just hoping for warm spring temps to hurry up and get here so these babies can really shine, but I’m sure these past 5 days or so of 17–18C have probably already made an impact on the final result, but we still have just under a month to see how it all shakes out in the end...

Looking good! Low temps can slow down growth. Low temps are more important at this stage. How about you try putting your extractionfan on a timer? Do 5hr on 1hr off. 4 times. Or maybe vent back into your grow space til warmer weather hits? Or use the same fan to extract another tent. That will slow down the air exchage, if you have another tent available?

Thanks for the suggestions slow, unfortunately with this tent my only option is to set up a timer, and pray for the warmer weather to arrive! My hands are tied when it comes to venting options... on the positive side of things the plants are all quite healthy and have a fair amount of budsites.... going to spend some time over the next few days monitoring and tweaking the timer cycles to see what works best.

Day 42 update (didn’t get to it yesterday)
So the Sour Cracks are happy once again! New light, new tent, and no temp issue! Oh, also they have the space to themselves... no more White Crack x Double Grape squatter suffocating them...

Hopefully the past 7-10 days didn’t affect the final outcome other than maybe extending the grow. I’d gladly have them go another 7-10 days if it means they will still reach the potential outcome I had envisioned 2 weeks ago! I’d hate for them to finish way short of expectations. But... that’s how the game is played I guess!

hi, pal, you have a great little garden :smoking:
