The Light Your Plants REALLY Get Will Shock You 

Glad you enjoyed! Thanks for watching 😁

Good to know!

This is a really underrated comment

Keeps you busy for sure 😂

Nice tactics!

Wow that’s great

Definitely!

I'm so glad!

Any time!

👍👍👍

Go for it! It’s good fun anyway

Cool, glad you found it useful!

Fab!

That's them trimmed! I like it for privacy

Awesome! Thank you!

Great point

That is awesome!

Glad it was helpful!

Ph is surprisingly important too

I leave them on for 12 hours

Sounds lovely 😊

Sure 👍

So true!

I have 10 plants now but that's abit too many for my big home any more would be too much. I how do you manage with all those plants

Thank you 😊

Yeah, I needed to put double sunglasses on 😎

@@_evangelina__ lol!

👍👍👍

Thanks for the tip

@@SheffieldMadePlants the Sansi bulbs are good though, I meant the generic “grow lights” that litter amazon and eBay

Great stuff 👍

My pleasure 😊

Glad it was helpful!

Fantastic! That depresses me slightly 😂

@@SheffieldMadePlants I'm sorry about that, do you want me to cancel the Sansi order? 😜😂

@@TheNetsrac no we all need it. Winter coming is the depressing thing 😂

@@SheffieldMadePlants I know, I was just being silly

Glad i'm not the only one 😅. So true about the science lab look

Thank you so much!!

Thank you 😊

Great stuff 👍

I've not tested that. One for the future maybe. Foot candles is a smaller number so i'll use that 😂

Is any unit intuitive? I'd argue probably not. I think feet used to be based on someone's foot at one point but no longer. A degree Fahrenheit/Celsius? What does that mean? A second? What is that? None if it has meaning until applied to a context that you become familiar with. So seconds, minutes, hours, feet, meters, etc. are all intuitive to most people because we constantly use them. It's probably rare for people to work with light measurements, so none of it will have meaning until you develop that context and experience.

@@plant-logic You can say all units are arbitrary and you need to learn their use contexts to make any sense of them, but some are more intuitive to use than others. Celsius surprisingly makes quite a bit of sense for 0 ℃ being freezing water and 100 ℃ being boiling water in normal atmospheric pressure, even if it's difficult to place a number accurately by perception (due to tolerable temperatures for touch and the material in question being a factor that changes the experience for how temperature transfers). It's still somewhat easy to approximate that 60 ℃ and above is quite hot, burning, and 40 ℃ being at upper end of pleasant. Metre is a slightly large step so not that unintuitive and foot is pretty much foot, inch roughly thumb. Foot and inch I'd argue are close to the definition of intuitive unit, having been born from our body measure itself. 1 kg is a carton of milk (obviously tied to region) or litre of water (10cm x 10cm x 10cm, roughly the distance between eyes). You do have some clue about how heavy things are from just the number until you reach objects that are difficult to fully grasp anyway. With the previous examples of units you're somehow able to paint a picture in your head, but megapascals don't become more intuitive even if you work with steel beam tensile strength and know that S355 has σ of 470 MPa. It just doesn't mean much (perhaps because you either snap a stick or don't, you don't approximate how many Newtons you need/can apply in square millimetre). On the other hand, light you observe a lot all the time. 10 000 or 30 000 lux just is a number on such a scale, while 50 being living room lights, that the numbers give no clue even if you have been in candle light or daylight. Where would 500 place with that knowledge? I don't think you could become too accurate in gauging lux or candle feet by eye in a room even if you did it for work. But for example a unit tied around daylight and scaling in a manner that felt more connected to how we perceive and experience light changes. Probably logarithmic since luminosity grows so extremely to daylight. To me it would make more sense if moonless overcast night placed at 1 instead of 0,0001, bright daylight to direct sunlight took the space of 9...10 instead of 10 000...100 000 and indoor lighting 6...7 instead of 50...500.

@@Yupppi I guess we are focused on slightly different things. It's taking me a minute to try to figure out how to how to clearly spell it out. I guess units are always tied to some kind of concept or context. But maybe these are different things... So we can have a concept like distance or temperature. Those are things most people are familiar with. Then you have Fahrenheit and Celsius. Those are different units of temperature. Yards and meters are different units of distance. They serve the same purposes but have different use cases/contexts. Aside from knowing meters are about 3 inches longer than yards, it's hard for me to gauge how they apply to different things. The idea of a 39 inch measure of length is indeed easy to grasp. However, it'd say that's not an intuitive unit. Throughout my life, I haven't considered distances in factors or multiples of 39 inches. I'd have to perform calculations or take measurements to grasp what I'm working with. The same applies to temperature. Aside from the easy freezing and boiling points you pointed out, none of the rest of the values in between have meaning to me. But if you give me any number between the oddly chosen 32 and 212 degrees in Fahrenheit, I can instantly understand how hot or cold that might feel and associate that with conditions where I might find those temperatures. I would say the Celsius scale is more intuitive than Fahrenheit without further context, but it's not intuitive to me at all. (one can dream of the day the US moves to metric) So even with some of the simplest concepts to grasp, I'd say those corresponding units aren't all that intuitive. It's not until you add the experience of working with those units constantly that the intuition develops. It's not like I'm an expert on temperatures in the 40-49 degree Fahrenheit range, but I have a much better feeling about them than what 40-49 degree Celsius signifies. So maybe the difference in how we're looking at intuitive units relates to looking at "what a unit is" vs "how a unit applies to different contexts". Going with the first "what a unit is", I think I agree with most of what you said. Looking at light, I think it's probably a much more difficult concept to grasp than something like distance. From an early age, we're constantly exposed to distances. We have our heights measured regularly. We play with blocks/legos and learn how they fit together. We grow and have to find clothes to fit. We're told school is so many miles away. Grandma's house is a different number of miles. We're also constantly exposed to light, so we're familiar with the concept. However, when do we ever see measurements of light? Until my interest in plants, the only place I recall is the non standardized brightness readings for TVs and monitors. We can call something dim or bright, but what does that mean? It's always relative to something else, but there's hardly ever a quantified measurement. I'd argue we have very little understanding of what's going on. The first time I took physics, it completely warped my view of reality. It's crazy how far off I was from understanding something like kinematics before learning some basic physics theories/rules. With my very limited understanding of light, I'm not sure it's possible to come up with an easy to understand unit of measure. The concept may just be too complex. A lot of the simpler concepts scale linearly, but sometimes that's not the case like you mentioned with a logarithmic scale. So even with a nice and intuitive starting and ending point like moonlight/sunlight, all the values in between may not have much meaning. A lot of people don't realize decibels work logarithmically. In your first comment you mention trying to decipher how candles might affect plants, but then there's even more to it. You've got PAR to take into consideration, and I don't believe lumens or foot candles really tell you much about how a plant will grow. So I guess the TLDR would be that when looking at how easy it is to grasp what an individual unit is, I'd agree some units could be considered intuitive. I think some units are more intuitive than others to grasp in this way. When looking at how units are applied in different contexts, I still think even the simplest units for the simplest concepts aren't all that intuitive. I can't really say one way or another if a simpler unit could be created for light, as I simply don't have a strong enough grasp of the concept of light. I've seen it around me all my life, but I don't have an intuition on how to quantify it.

Hey there!

Glad it was helpful!

Couldn't agree more!

You bet!

😁

👍👍👍

Glad it was helpful!

Time to part ways 😂

@@SheffieldMadePlants Oh my! I was gone for a couple of weeks for gallbladder surgery. I thought my plants were over watered. Nope. Thrips! 45 plants!

@@barbaraowens2299 😬

I thought I said that?

Yeah no way bright enough

Well worth it!

Needy little thing!

😅

Good shout 👍

Thanks 😆

They always do!

It’s tougher but I keep things away from the burning stove. It’s the lack of light that’s the problem

I’ll have a look

I was shocked too!

IKEA

Not sure about shadows. Seems a bit unreliable. The cost of LEDs isn't that bad really

LEDs are so LESS expensive to have on. I have them in all my light fixtures. I have grow lights on my larger plants. They help with the growth of my plants

Sounds great!

That all sound very technical 🫤

@@SheffieldMadePlants It is! I haven't been able to find an answer, yet. The daily light integral is useful, but it has its limitations. If it didn't, you could satisfy a plant's daily light requirement by blasting it with 9 million foot candles. Of course, you can't, but that's the point and my question: How much light can a plant use at any one time? Thanks, again, for your excellent videos!

Thanks!

Thanks for watching 😁

Yes you can

😁

Should say on the website which fixtures they fit into

I don't think i ever did 🤔

Mine came with a uk plug

Just seen the link on your amazon thanks ☺️👍

🤔

I'd be interested to know too

there might be free phone apps that can do similar things. don't know how accurate they'd be compared to more serious stuff though. some of my normal lights seem to measure up to a few thousand but they are probably a bit strong, grow lights seem stronger. and i think some light fixtures may focus the light more than others.

I've not no...

I'm dubious using a phone but i've not tried to be fair

Thank you Sir for sharing your valuable opinion about such apps. Undoubtedly, the meter would be a wise decision to use. 👍

Im surprised you can't find something off SANSI. They're all i use so can't recommend another

@@SheffieldMadePlants maybe they just keep selling out when I look? I'll have to check more regularly! I tend to have piss poor luck at most things so it wouldn't surprise me if my timing was just awful 🤣

Yep that's right

Nah

Nope

Expert moves 😁

😂 it's saying low light?

@@SheffieldMadePlants I mean, on a Portuguese, clear sky, sunny summer day my best windows give me not even in the vicinity of the 500FC's... (Lux app).

👍👍👍

Where did you get the 2% from? Light outside is usually much more than inside

@@SheffieldMadePlants it is, but in rainforests like the Amazon all the trees shade out the light and it gets really really dark even during the day.

Not sure what you mean. I thought I did that here?

@@SheffieldMadePlants I meant other plant channels who try and give advice. Sorry

@@teresawingbermuehle4212 got it 😁

Thanks for this tip! What is the name of the app you have?

@@CrazyPlantLady911 ​​⁠​⁠ Light Meter - Lux Meter by Coolexp Also converts to foot candle (fc). Has minimal ads but is free.

​@@CrazyPlantLady911check out Photone

Either is

I need that hedge for privacy

@@SheffieldMadePlants Have you considered fencing with some gaps plus some mesh netting so light still filters thru? I love this battle between light for houseplants and privacy! lol I went thru this and eventually tore bushes out. I got that lacey netting (not sure what it is called) for the windows.

@@theuglykwan I’m happy with the hedge tbh

Mad isn't it!

They fit e27

@@SheffieldMadePlants thanks!

I'm no scientist but isn't bright light bright light?

@@SheffieldMadePlants To a certain extent, yes. However the light has to be usable to the plant which not all light is ( I think between like 400-700 nm wavelength) and a unit such as PPFD is taking that into account whereas lux/footcandles are not

If you look through the different details on Sansi's lights, it even breaks down how the PPFD lowers the further you stray off an x and y axis from the center of the light. For a very affordable light they aren't bad to supplement sunlight with

However for myself, I need much more due to how much my new apartment lacks and had to look to brands like ViparSpectra or Mars Hydro to do the heavy lifting in my poorly lit space

I like the privacy 😁
