Then also the fact that it's plausible the slight reduction in size can be offset by a change in density. Often seen when grown under a more blue leaning spectrum tighter denser buds.

Can you think of a way to measure bud density so I can compare test to control buds?

My only thought would be accurate weight before a water displacement type scenario. Or maybe vegetable oil would be better? Something that does not enter the cell via osmosis?

a caliper that measures tension?

I don't know what that is. Got a link?

Dry them to 100% and just measure plant mass?

Can do, I have a freeze drier that works perfect for that.

But how do I measure the difference in density of 2 dissimilar buds in both shape and size? And what about all those nooks and crannies inside?

Here is the question - If the bud under UV stops getting larger but the internal density goes up maintaining the same weight as a bud that is continuing to get visually larger.

Stupid idea. Put the buds to be compared in the laser cutter. Cut them into perfect cubes. Weigh.

I have no idea if this will work or just start it on fire and get everybody high, but I'm willing to try, FOR SCIENCE! lol

If the buds are the same size and one weighs more when fully dried, it's denser, right?

OK, I'm picking up what you are laying' down

Bud A - UV Side ~ weighs 25 grams wet --> 5 grams dry
Bud B - No UV ~ weighs 25 grams wet --> 5 grams dry.

So same density? Maybe, but density also needs a unit of volume in the mix. So how do I make sure the buds are the exact same volume?

Density = Mass/volume

Maybe with the 3D laser imaging system that you have next to the exact replica of Neal Peart's drum kit?

you need to hire a certified 3rd party manual bud squeezer. They will certify and report bud squeeziness. Problem solved!

does his replica rotate and include an extra basic 5 piece jazz set?

A small beaker and something dry and grainy. Sand? Maybe too dense. Rice? Cous cous?

That could actually work. I've got this silica 60 I use in my column - it is very precise in the size of the crystals and is incredibly fine.

A bud in a beaker. Throw on top a known amount of silica. Vibrate. Measure.

Fukkin genius.

I love this place.

UVB is useless to cannabis. UVA is a different story. But even then I question whether it’s worth the extra expense for the lights and the power to run them.

I was thinking about this and i think you would want to mix in some of the measured silica (maybe 30 mL or so), then the bud, then the remaining silica. That way it doesn't smash against the bottom.

I'm thinking a graduated cylinder in layers from bottom to top

an inch of sand
freeze dried UV bud of precise weight (zero water)
sand to cover bud 1/2 the bud
shake it by putting it on top of a random orbital sander
more sand
shake
top it off with the rest of the measured sand
shake

Repeat process with control bud

stand the graduated cylinders side by side and compare. A denser bud should have a lower sand level. Could also cut the bud in half after to verify full sand penetration, but this stuff is really fine so I think it will get everywhere when vibrated.

Now the question is how do I get the sand out so I can smoke it?

Water displacement would probably be the best way imo
