- Making your own seed starting mix can be very rewarding and save lots of money. But if you just mix ingredients, there can be some negative effects from mixing in not enough or too much of any one thing. In today's episode we are going to be discussing the dangers of using too little or too much vermiculite.

Thank you all so much for watching and Grow BIG!
Sometimes I wonder how have we come to this point. Ages ago dirt was dirt they still managed to grow crops. I spend so much money and sometimes fail, then i see a plant growing in a crack in the sidewalk. 😢
So go ahead. Grab some "dirt' from outside and start all your seeds in them. See how well they do. I'll make my seed starting mix like I do every year and add it to the garden when I transplant my healthy, strong seedlings out there and enjoy my almost 100% germination rate over 95% survival rate of those seedlings.
@@tonileigh8660i want to argue with you. When i get germination rates above my current 20% i will try to haha.
Differences include the soil and the crops. In spite of imaginings about doing good ag, there is lots of proof that we do it badly. Our soil is bad and depleted but productive only by adding massive inputs. Terra Preta is 3 feet deep of fired pottery, charcoal, bones, clay and organic matter and results in untended islands of forest in barren landscapes. When your soil is rich with life and nutrients and porosity, most of the micromanagement is just unnecessary. Also our garden varieties are increasingly unsuited to natural competition as they have had no selection pressure in countless generations. Thats how it all looks to me, at my current level of ignorance so hopefully i will understand it better someday
@tonileigh8660 there was no need to be rude. She was only making a statement.
Geez, she was just thinking out loud. What beginner hasn't wondered about that? No need to be sarcastic.
I love more videos like this with measurements like how much coconut coir, how much perlite & how much vermiculite kinda like a recipe. At my age 10% of this 15% of that is too much calculating. Make it easy on the old folks who want to mix their own seed starting mix without going to school. I just want to play in the soil. Thanks 😄
I was gonna say this exact thing , I need a recipe. The percentage thing is to much for my brain. Lol
ruclips.net/video/PDri4FF7Jdk/видео.htmlsi=vQaLXI3XeeZQ7PDB
Yes, I would like the entire recipe broken into percentages divisible by five.
ruclips.net/video/PDri4FF7Jdk/видео.htmlsi=Ed3lfehBvngFM1OI
@@Anne--Marie???? 10% and 15% are both divisible by 5.
Made my own seed mix for years. Back in the day when I grew questionable plants, 25/25/50 perlite, vermiculite, potting soil did great. I now battle between soil blocks and containers, and also grow plugs. Still looking to find my overall sweet spot for seed starting. I feel every seed has their own sweet spot for temp, water, light and space.
Keep doing what you do.
I've been experimenting and came up with putting potting mix in the bottom 3/4 of the seed starting container and coir in the top 1/4. The seeds easily germinate in the loose material and the roots travel down for nutrients.
Thanks for the tip
I’ve done this too
I've tried this, too, seemed to work pretty well.
😮, that’s what I’ll try!
I’ve had not so good results in starting my seeds the past two years using just the seed starting mix. I like this idea. I’m going to try this. Hopefully this year will be better.
As a retired baker, I just want a recipe! Weights or parts but a recipe I can follow. If you want to give out that recipe that would be great and util then I will use Jiffy mix because it works well for my area. I try to avoid fungus gnats but a dissolved mosquito dunk in my watering can will take care of them and it is organic!
I agree! that percentage stuff just makes me more frustrated. I'm tapping out. Bye.
Just replace parts with scoops, spoons, or cups. A kitchen scale helps with weights. As for percents 100% is the whole thing, 50% is half of it, and 25% is half of the half, and half of that is about 12.5%. So you can eyeball it like that.
@@brandywineblue..the way I took this is: 65% peat or coco coir, 20% perlite, and 15% vermic. Which would be: 6.5 parts/2 parts/ 1.5 parts…. (He did say 20% perlite, right?🤔) 😊
@@cyhomer no I don't think he said to put both vermiculite AND perlite. Peat moss OR coco coir, aged compost, and perlite OR vermiculite
@@brandywineblue..he literally sat right there and added the vermic to the mix that had perlite in it…and he didn’t say ANYTHING about compost. Lol… .
I do 1 part potting soil, 1 part peat moss, 1 part Black Kow compost, 1/5 part Perlite, 1/5 part vermiculite and i filter the soil to get all of the big pieces and bark out of it and my plants grow fantastic.
What do you use as a sifter?
Great video, Luke! I appreciate you taking the time to demystify perlite and vermiculite and their individual benefits within your growing medium. We get to learn something new every day. ❤🌱
Awesome video: My mix, and the mix I teach my students. 3 Parts Peat, 1 Part Perlite, 1 Part Vermiculite : This is xDoc's Permaculture Seed Starting Soil. (What is a part) Using the same container to add everything. @MIgardener Thank You for a great video.
I'll challenge the "must have" emphasis of vermiculite. By the time you're starting to worry about nutrients and fertilizing your seed starts you should be up potting into a soil mixture with compost and/or other organic matter in it. that plus the peatmoss/ coco coir does a fine job holding on to nutrients (as much as you can expect for a container). top watering will always wash out nutrients in a container.
It would be nice to get a recipe done up in cups instead of %ages for people like me that have problems with the math
Multiply the total amount of cups your want (or quarts or pounds) by the decimal version of the percentage for each item. So, if you want 100 cups of potting soil in the end,, your equations would be 100 x .65 = 65 cups peat moss; 100 x .20 = 20 cups perlite; 100 x .15 = 15 cups vermiculite. (Using his measurements of 65% peat moss or coco coir + 20% perlite + 15% vermiculite.)
@@mlynnw7831 thank you for that!! I really appreciate it. 👍🤗
@jeanblair1751 I’m in the same boat!
there are 2 signifigant differences between peat and coco. 1 is ph. peat is 4.5ph and coco is neutral 7 ph. 2nd is water retention peat doe not drain or wick water near as fast as coco. coco you need less perlight/vermiculight. seed starting mix should be strile and no nutrients. potting mix no need sterile but should have nutrients.
My understanding of potting soil vs. seed starting mix is that seed starter is generally soilless and sterile. This is to prevent diseases like damping off which is usually caused by a soil-borne fungus. I used to lose a lot of seedlings to damping off when I first started growing from seed, until I switched to a soilless, sterile seed starter. Never lost another seedling to damping off since using a good seed starter mix.
Great video!
I have typically used ProMix, but I never see anyone mention it. What do you use?
@@loris.8323 I love pro mix for potting soil. I add some slow-release fertilizer to it and my plants to very well.
So once seedlings sprout in sterile mixture, how do they get nutrients to grow?
@@t-bone6467 I always transplant them into soil once they get true leaves. By then they are no longer susceptible to fungal problems. Or you can feed them with a liquid plant food.
@@357pls ok thank you for the information. Appreciated.
I use compost and perlite at about 50/50.
The compost holds a ton of water so the high percentage of Perlite helps make air space and keeps things from getting too dense.
I'm also generally not starting veggies, but perennials. So far it's worked for me...your milage may vary of course.
Lightbulb moment here - i didn’t realize how little vermiculite you need! This does a lot to explain why my seeds in my homemade seed starting mix did so poorly last year. I didn’t realize I was adding WAYYY too much vermiculite! Thank you for this!
In the early 80s, when I started gardening and information such as this was difficult to come by, I assumed that perlite and vermiculite were forms of plastic, so I refused to use them. It’s no surprise that I struggled in the garden!
This year I’ve made my own seed starting mix of equal parts worm castings, homemade compost, commercial “lobster compost” (all rubbed through window screen to eliminate chunky bits) and perlite. I’ll see how it goes…
I ALSO ASSUMED IT WAS PLASTIC OR SOMETHING MANMADE ?!!!! Going to have it in my GARDEN GAME FROM NOW ON!!!!
Ahhh kids these days have no idea what it was like pre internet. People just didn’t know stuff and went their entire lives not knowing things lol we used to get the words to songs wrong and just sing them wrong forever too 😂
@@LovelyIslandVacation-ch6wo People still get things wrong now because they learned something wrong and didn't double check.
well, you still have to be careful. I have found that plants I buy from the nursery sometimes DO have STYROFOAM in the mix NO KIDDING It is not perlite, it does not crumble, look at it closely and you will see that it is styrofoam. It makes me mad because even years later where I have planted one of these plants the styrofoam is still there!!!!
Luke, I think you should create a gardening science curriculum for homeschool! 😊
Thank you for the information-- I learned something! Any other videos about soils, mixes, compost, etc would be welcome!
Do you have a video on the differences between a seed starting mix and a potting mix? I will start my own seeds this year and assume I will transplant them into bigger containers over the 8-12 weeks before moving them outside to the garden but am not sure if I make a different potting soil mix. I feel like I do but I watched your potting soil mix video and it has the same ingredients. Are ratios different?
I don't use seed starting mix anymore and I start all of my plants from seed. Years ago, I used to buy seed starting mix, then graduated into making my own. I now use potting mix and add in worm castings and vermiculite. This way I don't have to up pot as fast. I don't see much if anything in the way of germination difference but I save my own seeds so I always have plenty. Seriously, farmers direct sow right into the ground. Took me a decade or sp, but I've learned, at least for me, starting mix is not necessary.
Wow, I literally bought vermiculite for the first time last night. Just sprinkled what felt right for my mix. But this video method is way better. Thanks Luke!
My brain can't handle figuring out percentages I just try to remember what each ingredient is supposed to do and mix with my heart lol I made my own seed mix last year and it did better than any I ever bought at a store. This year I'm using compost and coco coir as a base about 1 to 1 and then I think I'm going to add some vermiculite and maybe a little perlite if I can find some fine grain stuff cause I know I don't want the super chunky that I'd use in mix for full size plants.
I’m the same way- I do it by feeling
I use soil from my garden and sift it to very small size based off one of Luke's previous videos. (I use shade cloth) Then I'll just throw in a hand full of some larger size soil after I get it sifted and mix it in. So like 90% small stuff 10% medium. Ill just hand pick any larger peoces that made it in. I understand ver and per are better ways to do it but i have had pretty good success with this method as a completely Free option.
Also Luke is the GOAT! Love all his content
Indoors I use just coco coir to start seedlings. Then once they have their first leaves I up-pot and put their coco coir plug into a nest of typical potting soil mix blended with half coco coir. Then if they are staying in and not being planted out I move them to a foxfarm mix when they get to about a 4 or 5" pot.
If they are going outdoors they are placed into a custom mix I put in my beds. Which is basically 1 part vermiculite, 2 parts coco coir or peat moss, 2 parts compost, and 1 part topsoil or sandy soil mix. Have had great luck with this and the soil feels right, if that makes sense. This soil mix fills the top half to 2/3rds of the bed (Birdies legacy tall) and the bottom 1/3rd or half is filled with yard waste and logs.
Thank you! This sounds like the recipe that I needed!
Very informative video, thank you. I started gardening by following the sq. foot gardening method. Mel didn't make a distinction between perlite and vermiculite listing them both as an aeration component. My area experiences drought conditions most years. With that in mind I added vermiculite at 1/3 total soil volume. It ended up being a soggy mess. My plants got nutrient lockout from being over watered. I remixed it the following year and added pumice at 20% total volume. All was good after that. I prefer pumice to perlite for larger bodies of soil (due to the pumice floating).
I love how you use science and math! I am a 5th grade math and science teacher!😊
Thank you so very much for this video! I could not find vermiculite locally and my strawberry towers turned into cement. I will have to buy a bag online and I think I'll start with 10% since we get so much rain in Florida and up it in July when we tend to fry. Last year I learned to adjust my mix during summer because of our conditions.
One thing I hope to research is carrot soil, my carrots were pretty straight but the tasted like fertilizer and didn't grow that big - I think I purchased seed starting mix for them
Fantastic tutorial! Thanks.
You gotta measure the water, what the hay hay! Oh perfection???? What are we looking at youtube for? Get it Luke, your doing awsumm....! I love your videos
This is so helpful! (Thanks for homeschooling me and my boys today! Let the soil mixing begin!)
I'm the "too much" guy. But I love using Vermiculite. I actually use vermiculite over perlite but I will use the perlite like you said this season. Thanks for sharing!💚🌱🍀
Michigan here too. Great video! I thought these two work the same? I use self watering trays just started my first seeds under a week now.
I have heard several "pro" gardening channels speak of perlite and vermiculite as if they were interchangable, like peat moss and coco coir. Last year when I made my seed starting mix I only used vermiculite, no perlite, and after watching this video now I know why I had problems with my seedlings staying too soggy and having gnat problems :(
Thank you, I learned so much and this video gave me more confidence with mixing my potting soil for my garden this year.
Thank you, Luke! Great video of why too much vermiculite can be harmful.
I've mixed my own potting mix and seed starting mix for over 10 years. I've used the same recipe for years.
Now I know the "why" of the portions.
Looking forward to more videos. 🎉🎉
Excellent video! I thought vermiculite was a perlite substitute. I’m glad I know better now. Regarding perlite, what millimeter size do you recommend?
Sorry if I'm getting too pedantic but I've seen two methods of notating percentages
One where you start with final volume desired as 100%:
65 units peat
15 units vermiculite
20 units perlite
= 100 units final product (100%)
Another (baker's) where the base ingredient is considered 100% and the other ingredients are percents of the base ingredient's volume:
100 units peat (base=100%)
15 units verm (15% of 100)
20 units perlite (20% of 100)
Which one is used here? They've both got pros and cons.
The baker's method would require 65 units peat, 15 units vermiculite, and 20 units perlite to equal 100 units of final product.
he's doing your first list. someday, we'll join rest of world and go metric!
Well... This is great timing of the video for normal people who haven't started seeds yet, but in my excitement to start gardening, I've already thrown my soil ingredients together. I just tossed so much stuff together - promix, compost, perlite, and vermiculite - and mixed it all up. I hope things turn out this year, but if it doesn't, I'll remember this for next year :P
So.. everyone not in your growing zone is abnormal lol 😂
@@LovelyIslandVacation-ch6wo oh, I wasn't thinking of anyone outside of Michigan since he's MIGardener 😂 thanks for pointing that out!
I use perlite in my bucket vermin traps. Cheap, dump catches in my compost.
I will be making my own this year and am glad u did this cause this is all I needed left to research thank u❤❤❤
Thank you so much for helping me. Your videos are excellent. You are exactly right about this being the biggest issue with my starters. Looking forward to doing better. Also do you have a video on winter sowing in jugs?
Yes, learned something new. And understand now why my seedlings damped off last time. I covered the soil with vermiculite. Thought I had heard that somewhere. Guess not 🙈
This is a great video! Thank you for taking the time to share this!
I understand the idea of how much water is retained and shown quickly this is a good video. When it comes to a grow that would be interesting, if it is a non-tomato plant. And to see how the result is from the grow to labor result. So water accordingly, feed accordingly and what the differences are. And to measure grow result.
I buy 3.8 cubic feet of Promix at the end of the season on clearance. No mixing and works perfectly.
I use soil blocks and see different information out there about adding vermiculite to soil blocks. I do add vermiculite to my soil block mix. I’d be interested in your thoughts on it.
Yes! Thank you so much for this!!! I would definitely love to see more videos like this. VERY helpful!!
I love your videos they is so much information. I wanted to start gardening
Great tip Luke! It can also be use to help prevent algae on top of soil.
Great straight forward video with a lot of details appreciate it a lot. Yes do more of this type of videos and info that help us a lot in addition to helping our plants succeed. Also would like to know your mixes for propagation mixes for soft wood cuttings verses hardwood cuttings type propagation. Thanks again !
Thanx
I usually add vermiculite to the top of the seed starting mix to keep moisture in and I don’t have to water as often
This was extremely valuable. Thanks so much. This might explain why I had some troubles with dampening off in previous years.
That you for explaining the why and how in the mix.
Would hate to ruin my new migardener seeds.
This will help get the best out of my indoor startings.
Would you suggest Star losing the least base?
I love this video! I just returned from Lowe’s and was about to make my potting mix but saw this. I’ll have to grab some vermiculite!
Vermiculite is essential for a good chili pepper soil mix! You had me laughing at the "pour over coffee vibe" 😂. I hate the large chunks of wood chips in soil. I make my own as much as I can, but when I do have to buy soil, I dump the wood chips into the compost pile to finish then off.. lol
what about pomice? i like using that.. and also i use coots mix. 1/3,1/3,1/3 castings, peat, pumice
I use Pro Mix to start seeds then homebrew potting soil.
Compost+ topsoil + peat moss + vermiculite
I seemed to have missed whether you measure the soil mix before you add the vermiculite by weight or by volume?
I love the way you explain the how's and whys.Another great lesson.Thanks so much
Perfect timing! You explained that perfectly!
This was very informative, thank you! Curious if the ratio of vermiculite would change if using compost instead of potting soil?
I also wondered this while watching.
Look what about sweet corn in a small garden could you add vermiculite right as you plant it Just to help hold moisture and I don’t mean acres of corn
Love a good experiment
Have you tried to add springtails to your starters?
How would using duck water affect the growth rate of starters?
So what I got out of this video is some vermiculite is better than none, none is better than too much. (Like cooking it’s easier to add than to remove) but what about garden soil? Should I follow the same rule? Or is this not worth adding a garden? Sometimes I feel like the garden drains more water than it should when it gets dry in the summer. Will definitely need to consider some sort of mulch/straw as well, last year mushroom soil worked great as a mulch but I’m afraid it will add too many nutrients if I keep repeating.
Each test should have been the same moisture content from the start. Peat moss can hold 90% water so, of course, each fallowing test will be heavier.
I agree with you, this is not a valid test. He is taking the same mix that already has absorbed some water to it and it is absorbing more water each time. Should have started with a separate portion of dry mix for each test. Peat moss is hydrophobic and it takes time for it to absorb water especially when just adding water on top.
Thanks for explaining. Could you give the ratio in parts please, the percentage ratio is confusing
Thanks, Luke!
👍👍 Different grades of vermiculite I find puzzling.
I read in comments elsewhere someone used plain sand to start seeds, another used moist paper towels. Has anyone tried? I assume you’d have to up pot pretty quickly though
You can germinate seeds in a moist paper towel, but then you immediately need to get it into a growing medium (seed starting mix or potting mix).
I’ve used sand (kid play sand from Home Depot) in a to go tray to start seeds. Keep damp (not in a puddle) and then transplant once you get the first true leaves. It’s fun, and no fungus gnat issues.
Have also used ziploc bags with wet (not drippy) coffee filters (the flat kind). (Seeds on top of wet filter, not inside.) Zip completely. Stack them in a shoebox and check after 3 days. Plant germinated into potting mix. It’s fun to see the seeds sprout. Usually don’t have to rewet the filter if you close the bag completely. Helps you identify which seeds actually germinated.
I like both methods; ziplock is my go to. Not for those who are anti-plastic. If you are one of those, please spare me the hate.
This was very helpful Luke thank you😊
I was wondering what you think about adding worm casting to your seed starting mix ?
Oooh, good question!
I use a bucket and fill once with each peat, compost and vermiculite.
Just to make sure I am understanding this, you mix (by volume) 65% coco coir or peat moss + 20% perlite +15% vermiculite? And this is by volume, not by weight? Do you pour boiling water over the mix to kill off any gnat larvae, etc?
We had a large job where perlite was being used as insulation in large pipes carrying steam to melt oil shale and let me tell you, DO NOT LET IT GET IN YOUR EYES! Make sure you are up wind when you pour it because it is absolutely horrible when it gets in your eye
Great demonstration, helpful information.
Perlite holds water. We soak it and use it to humidify grow tents
In your video about gnats , we should boil the soil 1st, but it’s okay not to boil the vermiculite?
Hi, can you tell me how many times can I use the used potted soil from the previous summer or summer before? Thanks for your help
Does the Grade of Vermiculite matter? Grade 1 is Extra Fine. Is that too fine?
it doesn't matter as much honestly.
interesting... food for thought. thanks!
Love your videos :) However here, your base soil looked dark and not like coco or peat. 65% coco/peat, 15% verm, 20% perlite is what it looked like, but what made the base soil dark if this is correct?
the peat I buy looks exactly the same as his
Thank you
Mother Nature is always in charge regardless of the trouble and expense, or the good old sidewalk crack!
Great info! Thank you.
Question on vermiculite: Could you use activated charcoal the same way since it is supposed to hold on to the nutrients? Thank you!
I intensely dislike the "monkey see, monkey do" approach to anything. My brain doesn't do "just do it" (sorry - Nike 😢🤣), it needs to understand "why".
So your explanation of what each ingredient does is very refreshing (I 'had' Perlite completely wrong😢 poor stuff).
Your 'hidden gem' needs to be emphasised I think. That bark 'steals' nutrients was pointed out to me by a farmer friend who noticed that I was using bark as mulch as well as digging it in to 'add organic matter'.
The soil in my area is "very fine, very silty, aeolian sand" with practically zero organic matter and even less naturally occurring nutrients. It either doesn't drain (even in raised beds) and plants drown or, with the copious amount of bark I was adding, drained too quickly, leaching/flushing out any fertilisers I'd added.
A rethink is now due but in the meantime it's "hey ho hey ho it's off to find some vermiculite I go..."
I've added the link to this video under "Gardening" in my "My Recipes" app. "Lest we forget"... 😅😅😅😂
Another great informative video….ty Luke
Very helpful video. Can you put Vermiculite in a raised bed instead of coco-core? I am in Zone 10.
Just curious: Im using Coir this year, and I prefer to hydrate/wash/sterilize first. It’s also a lot easier to measure out wet. Will the recipe change drastically by doing this? Like, should I go to 6 to 1, since the coir expands so much? Or am I just overthinking things? 😅
I was about to ask the same since the volume change (wet vs unreconstituted) is extreme (±4:1 I think). I tend to think that reconstituting, allowing to drain and then lightly compressing would about do the trick. But I'd like some confirmation... 🙏
Many years ago when I first started gardening. (When I didn't know better...) I dusted my raised bed with vermiculite like I was dusting a funnel cakes.. 🤭😵💫
Percent by volume, by mass, percent of the whole or bakers percentages?
Also, thoughts on lime?
by volume sorry!
Hey, Luke! I love your videos, and purchased a set of seeds from you for the first time a couple of months ago. I'm excited to test them out during the new season.
For a more accurate scientific experiment (in which the dry vermiculite weight won't impact the final results in any way), you could let each test subject drain into a separate container, and then weigh the drained water instead of the water retained in each pot.
I have a question about recommended soil mixes:
What is the reason to have aspects of the growing medium contain moisture-holding substrate and also including a well-draining substrate? I understand there's something to it that is beneficial, but it seems so counter-productive whenever I try to make sense of it.
Thanks for all you do!
How would you measure the percentage? By overall starting weight? Good stuff in this video. Valuable for newbie like me.
Measure by the amount you want in the end. If you want 10 quarts of potting soil, multiply 10 x the decimal version of the percent. For example, if I want 50 quarts of potting soil, the following equations would be used: 10 x .65 = 6.5 quarts (65%peat moss or coco coir), 10 x .20 = 2 quarts (20% perlite), and 10 x .15 = 1.5 quarts (15% vermiculite). 6.5 quarts peat moss + 2 quarts perlite + 1.5 quarts vermiculite = 10 quarts potting soil. (You could use weight instead, if you like.)
@@mlynnw7831 Thank you for the explanation, I appreciate it and the example was awesome too. 👊
thanks for the info. I wonder if any of the premixed starter "soils" have this percent already mixed in with them?
I buy Burpee’s potting mix. Does anyone know if anything needs to be added to that mix. Thanks for any info.
You didn't mention the percentage of coir or peat moss in this mix. Also, I raise worms and have worm castings so that would be the other ingredient and wondered about percentage. I was going to use my own homemade compost as a base unless you think that isn't a good idea.
Thank for the inforamtion
If I have this right,
65% peat or coir
20% perlite
15% vermiculite
All pretty much sterile. And you don't start fertilizing until true leaves put on? Would love any and all opinions please.
TY
Can we get that converted to parts? Some of us don't use a calculator when making the seeding mix. 😂
It would be 6.5 parts peat moss or coco coir, 2 parts perlite, and 1.5 parts vermiculite.
