geologist speaking with a few nerdy things to add to this story: 1: the stuff that initially buried pompeii is called a welded tuff or ignimbrite, it differs from pumice in that it originates from an ash-flow that hugs the terrain as it flows down the volcanic slopes. Ignimbrite contains lots of sharp fragments of rock and lava of all different sizes making it look like a concrete with a gravel aggregate. Only the fragments typically have sharp edges and can easily get up to the size of a refrigerator or a car. 2: Pumice is usually created in an ash-fall, typically a column of ash gets expelled from a volcano, rises into the stratosphere and then loses momentum as it cools and collapses vertically, the fine ash particles stick together much the same as snow. 3: scoria is very different from both of these. Typically these are made from basaltic lava that is degassing. Bubbles are formed in the lava much the same as when you open a bottle of coke.
I transferred baby plants from soil into Lechuza pon by removing all the soil (I did it super carefully, it took me forever, and then I put the plants roots into water for about 10 min to remove the last bits). I didn´t damage almost any roots - but it takes a lot of time. Then for several months I watered the plants as normally from the top until the plant slowly adjusted it (it took me about 3 months, but could be more). I also put the pot on lecca with a little bit of water (water not reaching the pot) and the plant pushed its roots towards the water and it helped the process I think. I did it on baby aglaonema and alocasia silver dragon - they are healthy and grew nice new leaves. Lost only one oldest bottom leaf on aglaonema and none on alocasia. It works but takes time and patience. I used pon in self-watering system
Part 2 of earlier comment if you inoculate pumice bury it in soil it will grow a colony of beneficial bacteria and fungi all around it.in good soil you can dig up a piece and it will be covered with fungi looks like its covered with spider web this is very beneficial and it doesn't break down like perlite this is also why they discovered better plant growth on soil with pumice on top great videos 👍
LOL! ...SPG Shorts!! That's a great idea for merch! And one of them is wearing shorts in this video. All they need to do is add an embroidered monogram, "SPG"! 😂😂😂
I'm not an expert. I just think that whatever 'inside' depends on what I will grow (root type, heavy feeder plants or not, what size/how does pot keep the water (if I'm using container) etc. I really like this discussion. Please keep it on 🙏
Pumicecrete is by far the best building material on the planet Pumicecrete is a mixture of pumice cement and water mixed and poured into a set of reusable forms walls are poured from 12"to 24" thick pumicecrete is fireproof termite proof rust rot and mold proof and has a high R value and good sound attenuation solid poured walls means no critters can live in your walls Pumicecrete can be built for a fraction of the cost and time and pumice is one of the few building materials that can go directly from the mine to the job site ready to use without any additional possessing and zero waste Google all the walls of my house are made of pumicecrete
You have me completely sold on the pumice. In fact I have the need to repot from pumice to pumice but cannot find any "Tips and Tricks" video.....not even one covering Pon to Pon. Is there any tips or things I should watch out for when repotting begins this spring??
What is your opinion on IKEA “greenhouse” cabinets?? What are the pros and cons of those ikea still cabinets? what plants would do best in a IKEA greenhouse? Is there a better alternative cabinet? 💡 This is for people who don’t have a ton of space but want to build a friendly environment for their plants to thrive
I have pumice and calcined clay. How much clay should I mix in with the pumice to produce a planting medium for limelight dracaena cuttings that I’ve rooted in water?
Can you help and tell in which video they talk about measuring PH when using pumice? It's essential on semi-hydroponics but I feel like maybe it's not necessary in their method with puting plant to pumice without removing soil? Unfortunately I cannot find SPG adressing this topic.
Hello I would like to comment but it's a little off topic.I am a organic soil only Gardner medical herbs and vegetables I love pumice in soil it does hold on to beneficial bacteria and fungi which contains nutrients and water but you have to inoculate it before use.one square inch of biochar is equal to 100 meters of surface area incredible pumice is not as pourus but 2 big hand fillip of pumice
If repotting by placing plant and its soil in pot then adding pumice around it - is the pumice not being used for aeration or will it mix into soil over time?
Yes it can. Roots don't rot because of water but because of too much moisture. Leca, pumice, perlite, vermiculite, lava rock still hold a lot of moisture and if you water a plant too often and don't let the roots dry a bit, it will still rot. Roots can acclimate to this kind of moisture, but they must do so gradually. I would recommend to water as if in soil for the first month at least and then introduce a small reservoir of water (or a self-watering system). It's best to use transparent pots for this and keep a constant eye on those roots in the beginning. If they start to develop brownish tips, that's rot.
Har alltid använt fingret ner i jorden för att känna efter när jag behöver vattna växten igen, men tycker det är svårare att känna efter när det är pumice. Hur gör ni?
I always get a good start with pure pumice (with a little vermiculite mixed in for higher CEC) but invariably things fall apart and I notice green algae growing on top. What do you do to stabilize pH and prevent algae bloom?
Hi guys, Allow me.. There is a type of snake plant called many names Black gold Gold hahnii Bird's nest This is what the shop has sold to me as a snake plant I am not having any issue with this because it looks decent when placed in my bedroom beside the bed and got hereby convinced that a high plant more than 20cm cant fit in this place. But still worry if this would become of 20 cm height during my life time I noticedit has flowey shape which could be seen before getting deep into sleeping and while walking around the room This is better than other 36 species of sansiveria that could be tall upwards and see only leaf back side My personal view only Now i noticed when it has arrived in my room 2 things First it has refreshed and standed up little and the height from pot edge has become 8 instead of 7 while leaf sizes still same Second and i am not dreaming or getting illusions, there is a tiny fisherman rope protruded out vertical of the pot with tiny yellow point at its end and that was last evening while this morning the tiny tip turned into 2 tiny yellow leaves like those coming out of a seed germination What do you want This is your q to me I want to know exact requirements of this plant if it is really a part of snake plant family and i want to know what is coming from the pot out
@@benoitrosset7400 I have most of my orchids in leca and my houseplants in diy pon or leca. Still seeing a few gnats but have a few more to repot. I am worried about killing some of my rare plants and wasn’t sure if pumice would be an option for those and keep the gnats away.
The more I watch these interviews, the more I come to the conclusio just him speaking. Even the few words the humble colleague says is disrupted by his dominant colleague. It makes me very sorry for him. Yes, it can be this is your passion, pls be aware of how dominant you are. No offense but truth. He is just sitting, being led by him and the interviewer. Also shame on him. As an reporter you have to be sensitive to such issues. I would stand up and just leave. He anyhow knoes better, I don't get the chance to say anything. Emberassing. Really, just leave! If u can't believe just watch the other videis.. He really interrupts him, even he is talking so less! Both look so nice. Maybe he does not intentionally, but plss be aware!
Same thing, I use lechuza pon instead and my plants love it. The pon contains pumice, lavarock and zeolith so you do not have to add clay for cec. Do not use only zeolite

Thank you guys so much new plant parent I’m going in this direction along with some self watering planters
Fascinating! While I knew that pumice came from volcanic ash, I never wondered how it has come to be used in potting soil! Keep up the great videos! ❤

Great video! Could you make a video for Sphagnum moss for small indoor trees (like ficus and jade as indoor bonsai) and other house plants? Thanks! :)
“Our shorts”-I was thinking you’d be releasing some cool Swedish Plantguys merch! Thanks, as always, for this most informative talk. 😉
LOL! ...SPG Shorts!! That's a great idea for merch! And one of them is wearing shorts in this video. All they need to do is add an embroidered monogram, "SPG"! 😂😂😂
Me too!
Another great educational video! Thanks SPGs!!🌴🧡
Apparently pumice is like crack rocks for plants! Lol. I think my zz's and pothos can do without, but my calathea on the other hand I think needs it!
Does it matter what is the size of individual pumice rocks? I typically see them listed at different sizes with largest usually around 3/8” (~10mm)

Are there any type of plants that are not recommended for pumice? For example I have a lot of African violets and bottom water.
So,what are your opinions about LECA? Please do give us your answer. Thanks from Florida,USA
What else could the pumice be mixed with ? to have a good nutrients retention capacity, except vermiculite ?
I have pumice and calcined clay. How much clay should I mix in with the pumice to produce a planting medium for limelight dracaena cuttings that I’ve rooted in water?
Hi from the U K I want to use pumice as the substrate to grow lithops do I need to soak in fertilizer before planting.
Is adding zeolite is good for CEC? How much to add? 80% 20%?
Yes it is good for cec, you should add around 15% zeolith. It is the recipe of lechuza pon.
Do you want to try Pumice from Philippines? Looks gray color as well.
How do you add additional soil when re-potting around the soil with pumous? I ask because 2 loose materials going in at the same time.
Can you help and tell in which video they talk about measuring PH when using pumice? It's essential on semi-hydroponics but I feel like maybe it's not necessary in their method with puting plant to pumice without removing soil? Unfortunately I cannot find SPG adressing this topic.

Cat litter, non clumping unscented can be used?
My question is where in sweden can you buy pommice?
Love the videos. Do you necessarily need grow lights for your houseplants and if so which do you recommend
Could you please share information where we can get the pumice with pulverize clay here in Canada.
Bra jubbat grabbar :)
can a plant be overwatered if its completely only in pumice or similar mineral substrate?
Yes it can. Roots don't rot because of water but because of too much moisture. Leca, pumice, perlite, vermiculite, lava rock still hold a lot of moisture and if you water a plant too often and don't let the roots dry a bit, it will still rot.

Can I mix pumice with perlite ❤
Between pumice and perlite which one is better?
Plain clay kitty litter as additive?
How much asbestos micro dust in pumice? Some pumice mine and asbestos mine mix together.
What ratio of vermiculite to pumice?

Hi guys,
Allow me..
There is a type of snake plant called many names
Black gold
Gold hahnii
Bird's nest
This is what the shop has sold to me as a snake plant
I am not having any issue with this because it looks decent when placed in my bedroom beside the bed and got hereby convinced that a high plant more than 20cm cant fit in this place. But still worry if this would become of 20 cm height during my life time
I noticedit has flowey shape which could be seen before getting deep into sleeping and while walking around the room
This is better than other 36 species of sansiveria that could be tall upwards and see only leaf back side
My personal view only
Now i noticed when it has arrived in my room 2 things
First it has refreshed and standed up little and the height from pot edge has become 8 instead of 7 while leaf sizes still same
Second and i am not dreaming or getting illusions, there is a tiny fisherman rope protruded out vertical of the pot with tiny yellow point at its end and that was last evening while this morning the tiny tip turned into 2 tiny yellow leaves like those coming out of a seed germination
What do you want
This is your q to me
I want to know exact requirements of this plant if it is really a part of snake plant family and i want to know what is coming from the pot out
Thank you
Will pumice prevent gnats?
I converted my 30 plants with lechuza pon (100% mineral substrate) and I confirm that I have definitely eradicated the fungus gnats.
@@benoitrosset7400 I have most of my orchids in leca and my houseplants in diy pon or leca. Still seeing a few gnats but have a few more to repot. I am worried about killing some of my rare plants and wasn’t sure if pumice would be an option for those and keep the gnats away.
Zz plant just pumice?
What should you do if your plant gets root rot in pumice? Can you reuse the pumice?
