Pictures of your DIY lights - Post your pics!!!

I don't spay under my lights. I don't even water under them. They all come out every 3 days for health inspection, watering, etc. I don't advocate spraying anything on any light or mixing water and electricity. I have to raise my lights to move my plants, and that's what I do. Hopefully I have the downtime to setup an arduino and automatically adjusts light height in the future

didn't know you were spayed

Agree that it's a legit question, my aggression was more of a personal frustration with OneHit's inability to ever acknowledge anything positive regarding COBs in general. I should have just zipped my lip, but I was on the rag that day. Hope we can all smoke a bowl and get back to posting DIY light porn.:leaf:

Me too apparently, didn't mean to call you personally or anything, THAT wasn't my intention :joint:

Still we don't have a solid answer on LES and grow room conditions...it seems to lean towards being okay over a longish short term duration 1-2 years +.....still will their be breakdown?

I haven't seen any evidence, but MY eyeballs are poor indicators imho

@ stephen waterproof lenses with proper airflow would be the ultimate band-aid it would seem especially with KB offering 120 D lenses?
 
Here is one of the few brave enough to approach touching the LES

From a COB's perspective

That's usually what I expect to see if I don't go down there and adjust the lights for 2 or 3 days. He was at around 3-4 inches from the COB

3 days into flower (today). I saw what could have been mites so they were all pulled and sprayed outside of the tent, before before put back in.

IMHO, When people realize just how much healthier their plants are under led's they will take over. They say that 95% of a plant comes from light so a lot of nutrient companies will need to brace themselves whenever people figure out, oh..., I don't know,.........like,... it doesn't make any sense to feed your plant sugar derived from another plant. Plants manufacture their own sugar. That goes for most of the additives and other bs that people buy unknowingly to make up for bad lighting. These statements may just cause a war but mark my words. You can't make a plant do anything. Grow.......? It has no choice!

Most of the sugars added to nutrients are to actually feed microbes in the soil. Tiny bacteria are prolific at the rhisospere (root zone) along with mykorhizza (fungus). Now what most people don't realize is that these microbes are actually how 90% of nutrients are uptaken by a plant in soil (aside from water soluble chemical fertilizers that the plant must take up whether it wants to or not). Look up Cation Exchange.

The books "Teaming with Microbes" & "Teaming with Nutrients" are both great reads for anybody who is interested in plant biology.

Now I do feel that the spectrum probably plays a role in how the plant photosynthesizes and what ratios of different nutrients the plant needs. Other than intensity, I feel that is part of why plants are so much more vigorous outside. We could match the Suns intensity with HID inside, but the spectrum is not full so we would not see the same exact growth as outside.

Thanks do you think it was the paste that have out or was you using kapton tape and it lost its adhesion?

plants have "Active transport" for specific ions. Its not a matter whether they want or not. mostly only the smaller ions like NA or K that are absorbed passively.,
there is also the fact that while a plant does absorb some ions by osmosis, if they don't "metabolize them" ie incorporate them into proteins, cell walls etc. it just sits in solution, just like the blue dye in celery uptake experiments
 
Just thought I'd compare with 95% of what is being used at peoples personal home-grows.

Vertical hanging reflectors are far superior in terms of reflective losses compared to a traditional horizontal light. Not sure about the foot print at higher than 24".
Are most of these HID guys growing 24" under 1000w setup's?

I know my plants got hella crispy @ 24" when I did a run of 1000w with yield master hoods.
That's why I switched to 600w on my HID side.
