Organic Super Soil Recipe for Indoors

Most super soil recipes online use around 40 lbs
of organic and inorganic fertilizer inputs per cubic yard of mix. Here, we’re
going to use around half that. I want to create a grower-friendly mix for
cultivating fast-growing, light-loving, fruiting annuals in containers indoors
with a vegetative period of around 3 to 4 weeks before
switching to flower. My basic indoor organic soil mix for container plants is based
on 17 easily obtainable ingredients that fall into four main categories. And although it is basic, I am not. Fibrous textures, humic matter, aggregates and
nutrients– I will deal with each category in turn, and you’ll find the full recipe in
the video description below, for those of you who think I talk too quickly. A
concrete mixer is an ideal tool to blend all the ingredients together
homogeneously. First, fibrous textures: really important. In fact, they make up
half of the overall potting mix. 3 parts peat, 1 part aged redwood bark, and 1
part coconut coir, or 30%, 10%, and 10% respectively, in terms of the
overall potting mix. Essentially, these ingredients provide a physical structure
for your potting mix. All these components should feel light and airy, so
if your peat is compressed you’ll need to fluff it up a bit first, and who doesn’t enjoy a
little fluffing when they get the chance. Look for grower’s white spaghnum peat moss; I like the Canadian stuff, eh. Redwood bark should be ground up, aged at least 9 months, and from a
sustainable source. It should feel really light and soft. Coco coir should be hydroponic-grade,
not the ornamental stuff, so that means well-washed, and buffered to ensure low salt
levels. Next, humic matter. This makes up a quarter of the recipe. In terms of the
overall mix, we’re gonna need 5% humus and 5% worm castings. Humic matter is
essentially all about adding beneficial biology into your mix– friendly bacteria,
fungi, nematodes, and protozoa all work together to break down all the organic
nutrients into a form that plants can assimilate, which makes your soil alive! Aggregates make up the other 25%. They help to improve the
physical structure and porosity of your soil. They’re great for improving
drainage and air content–so important for healthy roots–and they allow you to
feed your plants more often. The 25% aggregates is made up of 4 parts perlite to 1 part lava rock. Lava rock is denser than perlite, so it doesn’t rise
to the top. This helps to create homogeneous
drainage throughout the media. So, that’s our base. Now it’s time to add the main
organic inputs, and this is where it gets very interesting, and there’s a lot of
scope for experimentation and discussion, but remember though, my goal is simply to
provide a broad spectrum of both quick, easily-assimilated, long-lasting
fertility for a quick veg period and then straight into 8 to 10 weeks of
flowering. I’m going to give you the doses in terms of pounds per cubic yard,
grams per cubic foot, and grams per liter. Bat Guano, AKA bat
poop, is an organic nitrogen powerhouse. Choose sustainably sourced stuff from
Indonesia. It contains up to 50% soluble nitrate– be careful it’s highly soluble,
so if you use too much, you’ll burn your plants. Some guano is low
nitrogen and high phosphorus, it depends on the bats’ diet, so always check the
label. Seabird Guano– cool! Fossilized sea bird poop, usually from Peru. Okay, it’s a less
soluble form of phosphorus, but slow release. Steamed bone meal. This is a
byproduct of the meat industry. It provides twice as much phosphorus as seabird
guano, and also calcium with a small amount of nitrogen; it’s less soluble than the guanos, but
compliments them because it’s slow release. Potassium sulphate: it’s a mined
mineral available in refined inorganic, or organic form. And as you’d expect, it
provides sulfur and lots of potassium, so it’s great for both flowering and vegetative growth. Highly concentrated, so do take care. Fine Dolomite Lime. We primarily add this for
pH stabilization, but it’s also a great slow-release source of calcium and
magnesium. Don’t overdo it, or you’ll lockout iron, which is a big no-no. Feather meal
is basically powdered protein– very high in slow-release nitrogen to keep your
plan green throughout their lifecycle. Azomite: nothing comes even close to
delivering all those super important trace elements at the right levels. It’s
mined from the Midwest, USA. It isn’t cheap, but it’s incredible stuff, hence you’ll see it
on almost every Super Soil recipe, and it also works great as a top dressing. Dried,
powdered Sea Kelp provides B-vitamins, growth hormones, and trace elements. Watch
out for elevated sodium though, and this stuff should be well washed. Finally there’s
alfalfa meal. This is relatively low nutrients, but it has good slow-release
nitrogen content, as well as Triacontonol, a natural plant growth hormone.
Okay, that’s it. Obviously, there’s a lot of other stuff you could add, too. I’ll flash
this up on the screen quickly, so get ready with that pause button. If you’re
starting off seedlings and cuttings, then I suggest you change my recipe so that
it’s faster draining, and less dense in organic matter. A quick fix would be to
blend it one-to-one with a soilless mix, such as VermiPro or coco coir.
Alternatively, you could buy a bag of medium-strength potting mix. Something
like VermiSoil would be ideal. The truth is you’ll have a hard time finding
true organic super soil in bags, hence all the DIY recipes on the net. At this point,
I should point out that there are amazingly rich and wonderful potting
soils out there, and yes, they come in sealed bags, which makes the ride home a
lot less messy. VermiSoil by VermiCrop Organics is widely regarded as friggin’
awesome, and definitely a favorite with growers. Notably, there’s also its
stronger and super potent big brother, VermiFire, which is arguably right
up there at the top end of what you can buy in terms of quality, decadence, and
richness. Proponents of super soils claim the stuff is so nutritionally
dense that it can take a transplant right through to harvest with no need to top dress or to add any liquid fertilizers further down the line. Sounds great in
theory, but bear in mind that super soils are too rich for cuttings, seedlings, and
young plants; you’ll need a lighter mix. Questions and comments down below, as
always. Please log into YouTube and subscribe to my channel. Thanks for
listening, and happy growing, amigos. This is Everest: star-shaped, spread-eagled, smeared
head to toe in seabird guano, and lightly dusted in dolomite lime. Bye-bye.

  1. I love super soil mixes, but I've research more on soil biology to maximize my grows! Nice video info. Look into Insect Frass!

  2. I love your videos man! I must have watched every single one over the past 2 days… You really have a talent for packaging the invormation and delivering it quickly and understandable to the viewers!

  3. Would you still be using nutrient water such as the Flora series or the masterblend with super soils or would you only use straight water and recycle it through the system?

  4. Dude! I think you forgot one of the most important elements in your mix… Where's your mycorrhizae? All so do you let it bake for a couple of weeks or straight use. What's your PH levels at with your mix? and awesome videos! love watching them!

  5. Another great post, I'd like to try creating this super soil one day. Might be a little too complex for me at the moment though, I'm still using the Canna line.

  6. Excellent video, Everest. I really recommend watching this video to all gardeners. I'm just about to revitalize some soil when I saw this video. Looks like I'm headed to Harbor Freight to buy a cement mixer. Will save me a lot of money in the long run.

  7. your videos looks great but I had to stop in the middle to look for other channels because I had to concentrate too much to understand and remember the informations. If you could talk slower that would be great, trust me you wont look like you dont know your stuff. Remember that youtube is worldwide and some people arent native english speakers. (I could find channels in my native language but there isn't).

  8. I like how you break it down for people who want to take supersoil to the next level but for people who think this recipe is too complex to try, Subcool's supersoil recipe is super simple and super effective

  9. The part where you said "where your peat is compressed", I thought you said penis. What followed was hilarious.

  10. thank god youtube can slow this down altho you sound stoned lol, love your videos but my god you speak fast ! breath man lol

  11. I want to make a good soil to put in a dual root zone in my aquaphonics system do you thank this mix is good or do you thank I should Latin it up a bit for the type of garden it is !!!!

  12. Help me plz! I've received my titan controls regulator for my 50lb steel co2 tank so i can enrich my indoor garden. I drove 7hrs to pick up my used atlas 1 controller and im trying to make sure all the settings are correct. I set my elevation and where i want my ppms to be but i dont know what to set my ppms when i try to calibrate it. Online people say the average ppms are between 300-500 so i figured set it at around 400 but just want to be as accurate as possible. Where should i set my ppms for calibration??

  13. Really great and informative recipe. I like the explanations for the ingredients. I use them every day but didn't even know what some of them do. I heard VM Organics got bought by scotts though so now they are basically monsanto 🙁

  14. If Everest talks too fast for you, here's a pro-tip:
    press ctrl+shift+j
    copy/paste this into console: document.getElementsByTagName("video")[0].playbackRate = .85
    hit enter

    .85x is speed the video will now play as.

  15. your videos are really long. you should talk faster to make them shorter, like my attention spa…..squirrel!

  16. not sure guano is sustainable and not sure i agree with more aggregate allows you to feed more. In that scenario less aggregate means less feeding, that we would all prefer; the reality of course if feeding the right amount either way 😉 thumbs up tho, i tend to worry about texture of the soil(less) mixes as oppose to the nutes that we add anyway 🙂

  17. There was a point that I gave up on you tube because I grew tired of sifting through 20 min videos for one piece of information. Watching your channel feels like the matrix. "I need a super soil program." Everything I need in a few minutes.

    I've been experimenting with a slow release SO4 by balancing levels of elemental sulfur and humic acid derived from leonardite, both bound with 10% benzinite. My theory is to break down S slowly without throwing off pH.

    Have you used elemental sulfur in your mix? A recommendation on levels in cubic feet or actually gallons for me. I generally mix one at a time.

    And thank you for videos.

  18. I like the fast talking, I feel that the other videos are quite slow. But some places do get a bit faster. For everyone who's having problems following, you can always reduces the play speed to 0.75x or even 0.5x speed.

  19. Do you have any books to recommend?? I just started a grow tent with circulated irrigation and am using 100% soil and pure water. Obviously a noobie. What supplements should I add to the water reservoir in my system? Appreciate ANY help!

  20. Can you touch on Compost Teas with super soil? The benefits of them..if they are needed…how they are used WITH super soil.


  21. oh fuck i spelt it wrong…."hilarious"……dunno if its correct this time but u know what i mean yr a funny man

  22. could you make up the base soil mix then just use organic liquid nutrients like biobizz instead of adding all those individual nutrients into the mix?

  23. if you use a lighter mix supersoil for your cuttings then once the plant is a bit bigger and you are transplanting do u transplant into something like vermifire straight?

  24. I mean, can you add supplemental liquid nutrients to a mix like this? is it safe to? how about foliar feeding? im pretty new to gardening and your channel has a lot of info btw. thx for the effort!

  25. Thanks for another great video. Im afraid you just lost two subscribers however: Uncle Ben and homebrewer :/ Oh well, they obviously dont need any new tips

  26. I wish somebody would do a UK super soil version. We can't get all the products you guys get and unable to complete the steps.

  27. My only input would be: for cannabis, less peat, more coco. Peat is very acidic. The dolomite lime will buffer the ph to some extent.

  28. hey everest, you're the man. I'd love to see what you could with a no till indoor bed. a lot of people say no till is an absolute no for inside. What's your opinion?

  29. Question why no Bio Char? hopefully you can help explain if this will help or hinder in a heavy feeder like cannabis. Thank you.

  30. Alfalfa also has potent allelochemicals that can inhibit plant growth; better to use in already well-established hardy plants 🙂

  31. Suppose you could make a video talking about custom tailoring a top dressing fertilizer for outdoor plants in this same manner? My google fu is coming up empty.

  32. Love the Info we love That SoilKing BIGROOTZ. Especially with all the nasty bugs floating around in the bag soil now days.

  33. or just buy some coco coir and some bottled nutes and cut out all of this mixing crap. great for outside…but indoors under lights…just go peat mixes or coco and some simple a and b bottled fertilizers.

  34. What might have been a very informative video is unwatchable, because for some reason you feel the need to spew 300 words/min. FAIL.

  35. how to keep seedlings alive!! after germination each seedling dies in about 2 weeks period.!! 😥😥 can anyone help,why🤔🤔

  36. Lolol … 3-4 weeds of vegetative growth then 8-10 weeks of flowering … WHAT COULD YOU POSSIBLY BE TALKING ABOUT?!?!?!

  37. I've used 1 part worm castings, 2 part perlite, 4 part coir, gaia green power bloom at 40g per gallon, and a tbsp of dolomite lime in a 5 gal pot. Works great. Lately I've been playing with high brix. Check out docbudhighbrix.

  38. for the dear love of whatever you cherish the most, please talk S L O W E R. I'm sure you're speeding the audio part. I'm autistic and it's difficult to stand. That's a pity because you have good content and production.

  39. Since when do you have to have a doctorate to make some fucking soil… 17 ingredients… Fuck your mother…
