Experiment: Do Pebble Trays Work? Testing if pebble trays raise the humidity for your plants.

[@peritapugnandi6624]

Hey Scott! 😊 I use pebble trays in my living room and it makes a huge difference, but only in fall/winter. By the way: I live in Germany. 👋 My plant journey began in spring 2020. Humidity level was between 55-65 %, very fine. But in fall I was shocked because humdity dropped to 38 % by using our heaters! I got several pebble trays for all my plants in that dry room. The trays are big in comparison with the pots. And humidity got to 55-60 % again. Even away from the plants were about 50 %. This was great along the winter. Our noses didn‘t get sore either. Now in spring again, there is no big difference to the last spring without pebble trays. At the moment 57 %. I kept them in their places, because I‘m to lazy. 😅 My theory is, pebble trays are good for rising up a low humidity. But if your humidity is high, it is more difficult to rise it even higher. And if you use a lot of trays like me, you rise the humidity level of the whole room as well (in my dry winter). Do you have an email adress for your channel? If you like, I‘ll send you some pictures. I‘ve got no instagram or facebook.

I would like to see how you are placing your trays. I need to increase humidity in my garden room in fall and winter for my orchids. I will be adding heat to that room when cold. I’m in texas

These curls thooooo!!!!!!!!! Forget the humidity tray, let’s get some curls video !!!

hi Scott. I live in a desert region in Arizona I've tried pebble trays over a number of years and a variety of plants and conditions, I've never seen a real improvement in humidity around my plants. I did notice those trays can be a haven for pests though. I bit the bullet and bought a humidifier, it's so much more helpful. great experiment, thank you for sharing this information.

[@michaelvaughan9157]

This was exactly what I was looking for. Thanks for spending the time

[@relearnalanguage]

How does this video not have a million views? Thanks for making it - it was awesome to watch and helps planning a lot!

[@jaclynns.jungle]

I like to put mugs of water on top of the heaters in winter to help increase the humidity lol. The humidifier I got certainly helps too though. Let me not kill this Calathea 🤣

[@siitupe]

Thank you for conducting this experiment and posting it. It makes sense that putting the water out that would increase the humidity at least slightly, if not more.

[@grzegorz__]

This experiment is great! Thank you :) I wonder if the increase would be still 3-4 % if you had repeated this experiment in some low humidity environment. ie. during fall, in my flat, there may be ie. less than 40 % of humidity. I wonder if the increase would be still 3-4 %, or, if the difference would've been bigger :)

[@joshuamohle4116]

For my tropical Nepenthes that which loves 70 to 80% of humidity I use a fish tank with a screen lid to keep the humidity high but allowing air flow

[@halfbakedplants9901]

this is cool! thanks for sharing, and i like the info at the beginning leading up to the experiment. i don't think 4% increase in humidity is worth it for the effort of having standing water that can attract gnats or whatever. like you said at the end, it won't increase from 30 to 70 percent. it's a tiny bump and may be useful for some folks, but it just doesn't do enough for me. I would love to see a humidity experiment like this where you bunch plants together. test humidity before and after a thorough watering, compared to plants that aren't bunched together.

[@ScottGrowsanAvocadoTree]

Thanks for your comment! I’m curious about more closely bunched plants now - I might need to test that out!

[@onionmagpie]

Great video! Very interesting and informative! I now know to consider the humidity and plants relationship!

[@KatFib]

Winter in Europe France, +1% or no difference at all :-) Actually, I did some tests after seeing "pebble trays advice" everywhere :-D I tried with several trays in one room. My humidity meter did not show any improvement even after being placed directly against one of the plants over 2 days. No impact on room humidity or local humidity. I'm happy to see that someone else also actually MEASURED the pretended impact :-D Good job.

[@lesliengo8347]

I think the results can differ if the size of the pebble tray is smaller or if there are multiple pebble trays. It can also differ if placed under direct sunlight versus shade. As someone living the the Pacific Northwest in Canada, we have high humidity but growing native plants indoors requires multiple pebble trays. I'm glad pebble trays work, even if it raises humidity slightly.

[@tamaranaszer9113]

Really informative and yet totally understandable, love it!!!

[@guess2300]

I loved this experiment! I have the same hygrometer btw and I have notice a ca 10& increase in humidity when I place mine on the edge of the pot of the plant, clay and with a moist (sorry) moss pole in the pot. I have an idea that a fresh watered clay pot will give some humidity away and I have also read that grouping plants together will give a better more humid microclimate for the plants. I've love to see something on that in the future. (Sorry if you already have, I just found you and will check out the rest of your videos now) Love from Sweden

[@denisekatz4355]

Love this easy to understand, informative and fun video!

[@j.a.velarde5901]

#ScottGrowsanAvocadoTree - This video was very helpful to me. - I just want to ask that you use more music variety and longer tracks, and that you improve your audio! - I have subbed and hope my suggestions help you grow your community. -

[@jaclynns.jungle]

This was so interesting to watch!!

[@ScottGrowsanAvocadoTree]

I’m so glad you liked it ☺️

[@bellsibub9951]

Interesting but I think it may have been more helpful if you moved the control further away.

[@amurphy8278]

I would be interested to see what it would do in an enclosed space. Most of my pebble trays are in a cabinet type area

[@ScottGrowsanAvocadoTree]

That is a terrific suggestion! … I’ll look into it.

[@elizautulo6862]

Hi. I'm just curious, why there should be pebbles on the tray? Would the result be the same if the pot is just in a tray with water? (Given of course that the pot is not submerged in water).

[@devinwalters8808]

surface area

[@deltatango6793]

How much water was in each of those cups? Should have covered them with plastic wrap!

[@johnnymula2305]

Im wondering about the humidity level only going up 3-4%. Is it really worth doing for that little bit of gain? I would think house plants, especially tropical varieties, would need at least 15-20% to make an actual beneficial benefit. Im in Arizona. Obviously we’re in an extremely dry climate. I would be curious to see how much humidity can be added to a room with a humidifier.

[@nickde6339]

No. But maybe in direct sunlight it could increase a lot more

[@kyletullyowns]

Unrelated, but aussie jesus, you have beautiful hair. BEAUTIFUL. Also this video is awesome thank you. I use pebble trays for my ferns in winter and they love it.

[@endor8witch]

your control and pebble tray are too close together. that's why when you put the plants there, there's always air movement even if it's not strong enough to be detected so it may move the humidity from the pebble tray to the control. that's why when you switched the position, then u get a more "Expected" result as the air movement is from one side to the other.

[@yadiaag7771]

I get constant humidity……outside When it’s cold and rainy at 40-55 Fahrenheit which most plants would probably die because they like 60-72 Fahrenheit My home is at 62-64 at its highest I bought a humid thermometer and it’s kinda dry in my home…..darn it

[@susandraluck25]

What is recommended humidity for non succulent houseplants?

[@LUIS-zk9oe]

What if instead of pebbles we use small chunks of wood?🧐

[@kyariscar]

i wonder the difference between cold, hot, and room temp water

[@samgutierrez4203]

Hey can I use perlite for the material to build the trey

[@GlitcH-lp9ou]

Hi, what happen if you use more porous pebbles for more evaporation?

[@ScottGrowsanAvocadoTree]

I love that question - I also wonder about the size of the pebbles. Things I might have to try in the future!

[@lovikate5900]

Can i use pumice or nah?

[@bendietrees]

You looking like plant Jesus
