So to actually continue the thread, I use COB LED chips. These emit photons; each photosynthetic islet in the leaf needs eight of them to make the proper charge for its chemical reaction.

And yet, spectrum matters a great deal to both performance and potency.

Yin and yang. Can't have one without the other. ...but artful mixing of the two makes tasty soup.

TT get your autocorrect in check dude. I too use a combination of white cobs. Add to that some t5 and a dash of blurple and the aforementioned uva/b t5.

Um ok, not that I want to exclude anyone who purchases their lighting and uses all their equipment in a stock form, my questions will apply to my garden in which my only unmodified light is a 24w t5 uva&b, I'd like to try building my own soil, cure equipment, and such.

Not tryn to be difficult but I would like to learn from your 10 years of experience.

Which bulb??

No opinion to have light is both a particle and a wave if you care to read any of the material the google search turns up. I in particular don't care what it is as long as the light makes my buds nice and green that is all that matters to me.

OK that is fair, and just how do you serve the light.

Some say a photon is a packet of waves, point is the question of how to grow the best garden can be interpreted in many ways and so far there haven't been any personal attacks on anyone's expressed view. Why? Y'alls care deeply about weed and less about the esoteric question of what is light. Yet people loose their shit about what is the best light without giving g it a second thought.

AT this point I can't afford the best spectrum and all that. So it's all about photons and flux.....

And of course watching and listening to the plants....and learning.


here is some opinions....works for what I am doing...

Quick Guide - Lux Levels for Optimal Cannabis Growth

Life Stage MaximumGoodMinimum
Vegetative 70,000 lux 40,000 lux 15,000 lux
Flowering 85,000 lux 60,000 lux 35,000 lux

< 15,000 lux - sparse or "stretchy" growth - plant isn't getting enough light
15,000 - 50,000 lux - good amount of light for healthy vegetative growth
45,000 - 65,000 lux - optimal amount of light for cannabis plants in the flowering (budding) stage
70,000 - 85,000 lux - a lot of light, some strains do okay at this light level, but some plants lose their top leaves early under this light intensity, especially plants that are not resistant to heat/light (like many indicas)
> 85,000 lux - at this light intensity, you've hit the plant's "saturation point" which means your plant can't use all the light. ( bleaching can happen. )

Light Requirements of “High Energy” Plants

Amount of luxPlant Growth
1000 – 5000 lux Min. necessary for life
10000 – 15000 lux Min. necessary for consistent but sparse growth
20000 – 25000 lux Min. necessary for robust growth
25000 – 30000 lux Max. Efficiency for Sub Tropical varieties
25000 – 50000 lux Max. Efficiency for Equatorial varieties
Plants need 25000-50000 lux too grow fast.

@Uberknot there are a number of ways to do led on a budget but ask yourself what would you change? Or where along that lengthy list of lux readings are you lacking?

Right now HPS but once I have more room I will have several spaces dedicated to personal research using other light sources. I want to see how far I can push a plant using a single cheap CFL one day. I'm sure with the right conditions even a weak light can produce a reasonable yield.

None of them. I get 15k-20k minimum all the time at the pots. if I turn it up I get 70k+ at the pots.

That's at like 24-30 inches...

DIY 4 COB light working just fine.

If I could change anything I would make pot legal so I could grow anywhere all the time. :D

I have a pretty far flung brainstorm on that one. But the technology hasn't been invented yet.

Quit whining about the unimportant stuff.

I think a solid combo of broad spectrum light plus a bump in the deep red and some UVB and you've got the right light recipe.

That's not the whole equation, however.

Yup, it doesn't have to be complicated. Well at least when you look at one part of the eq at a time

I found a killer deal on some LED light bulbs for $1 each brand new at the good will they had 80-100 of em so I bought 16 and put em all over the house.

Maxlite 9w 2700k @ 800 lumens with the plastic cover on. I wish they had some 6500k's :P
