What Is The Best Soil For Growing Cannabis?

Marijuana growers need to make many different decisions when they are planning out how to grow their plants. It starts with whether to grow indoors or outdoors. Indoor growers need to choose whether to use soil or a hydroponics system for their indoor setup. In case you haven’t used hydroponics before and are willing to dedicate the money to it, it can be a very practical option to choose.

 

Generally speaking, newer growers decide to grow their plants in soil at first. Taking this step allows them to get a feel for the undertaking of growing marijuana plants without risking huge amounts of money and extra time spent researching. Either route can be useful, but in this article we will cover information for people who want to grow their marijuana plants in a soil-based system.

Growing marijuana in soil

marijuana soilMarijuana roots extend deeply into the soil as they hunt for the best sources of water and nutrients. This is why indoor growing requires a different technique that will compensate for this lack of space. To put it simply, the root systems of indoor marijuana plants need to be smaller. The water and nutrients come from the grower rather than natural sources in wild soil, so root systems should be able to thrive without extending out too far.

The main thing you need to worry about with root systems is that the temperature stays relatively warm – around 68 degrees Fahrenheit. You will also want to check that there is plenty of water and oxygen throughout the soil. Make sure to download my free marijuana grow bible at this link here for more growing tips.

marijuana soilPros and cons of soil growing

Irrigation is more easily done in soil because mistakes are more easily made with hydroponic systems. Fertilization is also simpler, if only because people have been growing plants in soil for thousands of years, meaning there is tons of information and advice out there. Soil types can make a big difference in the taste of the resulting marijuana, which is an added bonus.

Soil isn’t perfect, however. It requires lots of space and weighs a lot, making things rather difficult for people growing indoors. Pests and insects are more likely to be found in soil as well, not to mention the fact that some people simply don’t have the “feel” required for growing any plants in soil. Read the article ‘How To Grow Marijuana Hydroponically‘ if you don’t want to grow in soil.

marijuana soilMarijuana soil container size

The size of your plants’ containers will alter the size of your plant’s root system. If the roots have more space, they will fill out their space even more quickly – making growth easier. Problems occur when the plant outgrows its container.

Regular sized marijuana seedlings do well in a container that is 10x10x10 centimeters until it reaches the height of between 25 and 35 centimeters. At that point, you will need to transplant it to a container that is two times the size of the first one (15x15x20 centimeters). When the plant surpasses the 80-centimeter mark, you will need to transplant it to a container that holds 10-12 liters. The container size keeps increasing as the plant exceeds the 1-meter mark, and so on.

marijuana soilMarijuana soil nutrients

Soil already has lots of nutrients naturally, since it is made up of organic materials. Materials like rotting vegetables and animal manure cannot be placed directly on your plants as fertilizers – they need to be broken down additionally before they are able to be absorbed by the plants’ roots. Worms and insects are useful “tools” when breaking down these materials, as is rain. Water dissolves these and other materials allowing them to be absorbed by the marijuana roots.

While these things happen easily and naturally in the wild, it is not so in indoor growing systems. That is why beginning with soil that is rich in nutrients (as well as sterilizing it before planting) is so important for indoor growers. The best way to sterilize soil is to use heat, which is not 100% effective but will help ensure the safety of your plants nonetheless.

Nutrient-rich potting soil mix can be found at your local garden center, and it can also be made on your own. Oxygen, a lukewarm environment (approximately 20 degrees Celsius), plenty of water, a balanced pH value, and lots of nutrients will create an environment that encourages healthy growth in any marijuana plants.

As an indoor grower, you will have to be especially aware of what your soil needs to contain. The pH value, humidity, and nutrients will make a bigger difference than you might expect, so keep tabs on these things. Additionally, if your soil doesn’t retain water well, plants won’t have time to “drink” as much as they need to. Too much water retention, however, can encourage fungal growth, which would lead to devastating root damage. Use vermiculite, sphagnum moss, turf, or perlite to alter the retention of your soil.

marijuana soilMake marijuana soil yourself

Soil is pretty easy to mix, as long as you pay attention to the ratios. These ratios also will change according to which stage of life your marijuana plants are in. Early stages of life, for instance, require balanced amounts of turf, perlite, and worm meal. Vegetative and flowering stages need balanced amounts of turf, worm meal, and compost instead.

To decrease a too-high level of compost, simply add chalk. You can also use liquid fertilizers as a way to add nutrients to your soil, and they can be made yourself. Just be sure that the liquid is homogenous and has equally balanced nutrients, thus preventing it from “burning” your plants. For nervous beginners, a store-bought option is probably your safest choice.

Watering marijuana soil

Watering in soil can be difficult because it varies according to the soil type and environment. Hot environments need more water while cool environments require less. Water works to move necessary nutrients and minerals to the roots, where they are then transported to the rest of the plant. Water also works to cool down plants when they are too warm and to keep the structure in line. Perhaps most important of all, water is a necessary ingredient for the process of photosynthesis to successfully be carried out. As a general rule of thumb, simply water until the soil is moist but not wet to the touch, unless you want fungi to grow and harm your marijuana plant’s roots.

    When my ex grew…..he would use, cow manure mixed with black dirt, bone meal, and bat (guava) poop. 5 gallons of water per day. And the holes for the plants were approx. 4X4X5′ deep.

  • Mugen

    Greenies? Seriously? I unsubscribed from HMJ to get away from their juvenile BS and desperate attempts to appear relevant, very disappointed to see it getting reposted here.

    Also, if you really want to know about good soil mix for growing high-quality cannabis, one vague paragraph isn’t going to do any good. FFOF might do okay for some dude growing a single (not very healthy) plant in his closet, but there’s simply no substitute for doing a little research, and there are some pretty great resources available that are completely dedicated to growing.

    • Dirty Dave

      Fox farm is the best dude I don’t know what you are talking about I look at this site everyday and some of the bestest articles are hailmaryjane ones you are smoking too much crack

          aye?

  • hellarella

    So what do you do after 2-3 weeks? Have to use a bunch more stuff to finish the growing cycle?
    If it is so good then why will the neut only last for 2-3 weeks?

    • smarterthanyou

      dumbass youre supposed to use nutrient supplements via water after the first two to three weeks, not add more soil you fucking idiot

  • refurr

    fox farm ocean forest hasn’t let me down in the three years i’ve been using it. it is basically set up for vegg cycle, that’s why it needs nothing for at least 3-4 weeks. 4th to 5th week start using nutes to prepare for flowering. have mixed several variations of my own soil over 20 years and after side by side grows, found ocean forest to be as good if not better than anything. one thing is, never had problem with ph using ffof during vegg or flower. fox farm products are great, however i prefer advance nutrients for flowering stage. big bud powder is the SHIT!!!!

    • Miff

      Just guna start a grow mate. I have took ur advice on the soil . But when watering them do u still need neutrions in the water. And if so which? Do u change the soil after 3-4 weeks . Could u give a breif description on th stages if ya could.

    i just finished my first grow it went great but i had some help first i started with some great seads i orderd from everonedoesit.com.planted 5 only 1 male but the soil my friend said to use is a coco base named sunshine advanced mix#4 i never had a ph problem it is about as close to hydro u can get without the headach of the hydro system

  • olkev

    I’m new at growing. I want to use soil and you all have made my head spin. Makes me want just to use MG. I know you all said don’t, buy good stuff. I want to make this easy. So, someone please tell me what kind is the best but don’t cost big bucks. I also have another question for all you pro’s. My grow closet is 4’x3’deep and 7’feet tall. I want to use CFL lamps. How many and what wattages. Please help this 1st grower…Thanks

  • Aga Khan

    @olkev Growing in soil is not that hard. You do have to be a little more patient and little screw ups that get fixed in a day using hydro can take days to fix using organic methods. If you are overly confused just start small and keep it simple. Buy a good quality organic potting mix. groworganic.com is a great place to start. They have plenty of how to videos regarding organic farming. If you need to talk to someone they have never failed to help when I have called.

    Once you have settled on the mix you will need to fertilize as the standard mixes don’t have much nutrients in them. Make a tea it is very easy to do. Just make enough for what you need and mix a new batch every third watering. You can make the tea from worm castings and bat guano in a 5 gallon bucket and water.

  • bling bloom

    Just lookin for new knowledge first time grower at 2 and a half weeks leaves yellowing should I give them nutes already what kind

    • doesnt know sht

      ive read that it can be salt build-up, too many nutrients, too little nutrients, or just a plain unhealthy seed, im sure there can be more but thats just off the top of my head, i’d look around a bit yourself though, youtube has alot of educational clips
      good luck

    • The yellowing of the leaves early on in the grow period indicates that there is a lack of nitrogen. About a month in you should have already started using nutrients.

      • The best I have ever seen grew wild there are nutrients all around you, if leaves start turning yellow not only is there a lack NO2 there is a CO2 defficiency.

  • doesnt know sht

    hey guys can i use “hydroponic” nutrients in a soil growed plant??
    also another question, i bought fox farms tiger bloom for my nutrients during flowering but im wondering if i fucked up and should use something like big bud powder like reffur mentioned having a higher potassium content instead of phosphorous
    i havent started my first grow yet btw, just gathering supplies and knowledge b4 i attempt so any advise appreciated muchly thanks

    • No dont use hydo nutes in soil settings bra.  

    • Cliffyscuts

       Yes you can if you use sand and rock  see above post pure sand is just like indoor hydro taste with outdoor ease…..   hard to over water or over feed  drains so good …try it I have grown alot out doors and I have never got the indoor taste like I do with until I started this program…

      • Alex v

        Why would u want indoor taste from outdoors? The best thing about outside is the taste.. indoors u get potency and outside u get that earthy inhale.. Ibjust dont get it u straight delivered an oxy moron

  • Matthias

    what is the best solution for spider mites tried every remody, dont say neme oil how ever spelled but i cannot get my hands on that right now im asking the quick fix

    • Valerie7075

      Molasses water. 1 tsp per gallon

    • Midnight train

      Floramite . From australia. The ONLY THING THAT KILLS MITES AND EGGS. DONT FUCK AROUND. GET FLORAMITE DONT SPRAY SUGAR ON UR PLANTS THAT WONT DO SHIT BUT HURT EM

    • Chisna

      I’ve tried them all. Including neem. Best solution I’ve found is blast em off with water or a air compressor. Do this every 3 or 4 days until you don’t see them any more. Spray down your empty room or tent with Lysol or a strong bleach water solution. Wipe down…And repeat process as soon as you see them come back. Which you will… I have seperate veg. and flower rooms. And between rotations I spray down the room even if I don’t see mites. Others may have things that work for them. This is what I found works for me.

    • lady bugs or praying mantis is a good way just put 1 mantis or couple (6) or more lady bugs that will get them

  • PermaFry

    how much of all this stuff will I need if I plan on growing only 1-4 plants?

    • PermaFry

  • Nathanwest66

    PLEASE HELP- first time grower here, i have germinated some seeds and started them out in Miracle grow soil, they are only about 5 inches right now, in 3 days im going to try a good soil mix like the one u have up above in 5 gallon pots, would they be ok to transpant them after that long from miracle grow soil to one like whats above??

    • Cliffyscuts

       When you harvest you will see that it tastes like commercial weed…….. See the post above about growing in sand and rock, I will never use soil again!!!!      Indoor taste outdoors , its all in the chemicals you feed it…… 

  • Floridabadger

    I’m trying out using a cow manure type of soil! W/the knowlege + growing tomatoes & watermelons last year w/fantabulous results till sun got too hot outdoors here in FL! Now I’m utilizing a newer bulb, cfls/real curly type that is next best to sunlight! Mixed in perlite for aeration! w/rocks in bottom also! So far so good! Would like replies as to wether thid is a good Idea/plans for closet! Starting out w/bulb 24″? or so above to be pulled uo as plants grow! Also have a mirror w/Al on walls! We’ll see! Going from an old Conniseurs telling me that u can never use too much coe poop! Am looking forward to replies! Thanx!!

    •   cow manure is good,but,yes you can use too much of it, high in nitrogen,it will stunt the growth and turn the leaves a sickly yellow/green..

  • Floridabadger

    Another trick was germinating till leaves were fully exposed, then I made a hole w/finger, and put all the way so after filling hole just tops were out in hopes to keep plants low & full!! Kinda new@f9f11c2b173827b3ef69cd59107a6646:disqus  this so only time will tell!! Would enjoy corrective criticism please! From a fellow Head!!! THANX!! Happy tokin to all eho can! I.m doing all I can to get Medical cuz I could come offa Too Many pills! To pursue what I KNow is best to make me smile while being comfortable!! Happy Mothers Day to ALL Moms out there!!

  • Mark

    I have an outdoor garden and would like to know what the best ratio of fertilizer is. I found miriclae grow and it is, 12-4-8
    is there a better one?

  • Tollion

    Nothing like good old ‘Volcanic soil’, have grown the strongest of weeds in this natural dirt..This is the most balanced soil know to man…

  • Gwcliff

    WHAT WORKS GREAT FOR ME!,COST NEAR TO NOTHING, EASY, NO WORK TO SPEAK of.. You should know about the stages of plants and have some basic knowledge…  I use 7gal or ten gal plastic pots with holes   Fill half with hydro rock… the rest with sand plant and use under 75$ in hdryo chems I feed it 3 different type 1 each day 4 day water only you can water as much as you want.. Dont let chems build up. Add 2 chemicals for budding. Mix just like hydroponics, the water drains good, be sure to  clean chems out for 3 days for taste brfore harvest..  Sunlight!! no ele cost… Hydro taste   but better Hands down the cheapest and easy way outdoors I have ever done with the indoor taste and outdoor kill factor…This all = great taste all for under a 100 bucks and I have spent 1,000 s on all the indoor crap   Try this and you will not grow indoors.. 

    • Cliffyscuts

       Each plastic container is half rock half sand… just for clarification… gets the all nutrients from hydro chemicals just as a   indoor system 

      • John Cottam

        half sand half rock? mixed? or sand on top?

  • mirren

    hey troops, have 4 cuttings rooted and ready to pot, whats the best soil for this early stage?

  • Tyler Durden

    Try some Fox Farm soil, it should have enough nutrition to last you for about a month before you need to supplements with additional nutrients.

    • Goodpif

      Which fox farn nutes should i use after a month

  • Jwilliams198708

    Im a first time grower I need someone with good knowledge to give me suggestions on how to setup an outside garden measuring about 12″7 what equipment will I need suggestions are helpful

    • Jwilliams198708

      12″3 sorry

  • Xhapoch

    Above, there are directions for preparing soil and goes like “Once placed in the containers I water it slightly adding 3 gallons of water to a large garbage can full. It will make the stirring harder next week but it will activate the Mycorrhizae and I think help all the powders dissolve.So now we add water and let it cook in the sunshine. 30 days is best for this concentrate.”  I am confused here about the water being added when, how much, etc.  Seems like there is some missing information here.

    • Dave

      also how much Mycorrhizae do you add?

  • DEUCE DIME

    ^Can’t U Juhz Grow Reggie Wit Juz Soil??

  • Billybaggz

    I found a round egg on the top of my soil then I squeezed it and it popped like a lil ball or something…what is it and should I be worried

  • The Real Grower

    Just use Scotts Miracle Grow Soil. It feeds for 3 to 6 months and no need to check the ph level since its already good dirt.

    You might kill a plant giving it that much food.

    You don’t want to kill your tomato plants.

  • So what about using fine sand for after the germination but before the bigger pot transfer? Do you think this will help retain the initial moisture and guides the root to dig deep for the soil?

    COMPOST! worms

    The best soil is only 1 part of the equation. How fast the soil drys , how much nutrients to give .
    Jorge Cervantes has some good books ,websites ,youtube.

    Another good source is “bio-dynamics” Stieners belief that herbs and weeds removed by man actually regulate molds ,diseases. re-introducing these organic plants or applying to garden compost helps plants thrive in an organic environment

    SubCool has some great vids on youtube and I have only heard good things on his Vids

    back in the day , we had to hide this, We parked our cars miles away from the hydro shop ,paid cash ,told no-one.
    Now information flows freely on the Net
    To all Newbies the best advice I have heard was “whatever keeps it green”

  • FEDupWITHstupidity

    2-4 people can easily mix large quantities by laying it all on a drop cloth or heavy plastic square shaped tarp. Have each person stand on one of the sides of the tarp. Each person grabs on and one at a time take turns lifting their side high enough to push the dirt to the center and beyond if possible. This is easy and there is no need to jump in and get dirty. You can use your legs to help with pushing your side to the middle. After 5 minutes of mixing, it is thoroughly combined

I need help pls ???

    • Jay Millz

      What the fuck? If you’re going to depend on the sunlight from outside to give them light then plant them outside for god sake. You need to buy some lights if you want to grow them indoors or otherwise you’re going to end up with dead plants. Also your light schedule should be 18h on and 6h off.

    • Nick

      I would reccomend germinating your seeds in a glass of water for only 24 hours or until the seed splits and you are able to see the taproot. Germinating in soil takes much longer and can be much more tedious.

  • Dave

    You said ”I will use this mix for a full year just adding like 30-50% in the lower
    potion of the container and plain base soil in the top portion.” Do you reuse the soil after the plant is done or you use the left over mixed soil in the trash can for a year?

    How much Mycorrhizae do you add?

      Looks lile the soil has burnt the plants. What you should look for is the NPK of the fert that has been added to the used soil*. Different plants have different needs, one soil mix does not accomodate to all plants.

      *I just assume it is used with ferts already in it.

      i have heard that 2nd hand soil is absolutely useless as it is full of burnt out nutrients,. We have been told never to use it twice.

    I realize this thread may be inactive, but if there is still someone on the other end, I have 2 questions – one about scaling and the other about procedure.

    1) Do you end up using all 8 bags of base mix? Meaning that if someone wanted to make smaller batches, they could divide all other ingredient quantities listed by 8 to obtain a per-bag recipe.

    2) Is the 30 day ‘cook’ period mandatory? Can it be reduced within an acceptable range?

    THANKS!

      In answer to your 1st question, yes of course you can, the 2nd is mandatory, it needs time to brew as it were.

  • All of 12 soil textural classes loam soil is the best for most of the plants cultivation. Because loamy is the intermediate mixture of sand, silt and clay. In loamy soil the three major components of soil remain in suitable amount for plants well growth.

    Hello, I accidentally bought soil which contained wood chippings. I also read that it is not a good thing to grow weed with wood chippings. Can someone tell me why it is bad? I might have to buy more soil :(

    Has anyone tried BuffaLoam? I heard the buffalo compost can be used without nutrients.
