    Default Subcool's super soil (UK measurements) - Just add water

    Hey gang,
    So I've been planning out my year on the growing side of things. I'm just getting back into it after a hiatus so I'm starting from scratch.
    I like to grow on soil and as organically as possible. I've tried other mediums and soil really is my favourite so this year I'm looking at making some of SubCool's super soil and cooking it up over the summer (save waiting 60-90 days in this cold weather.
    So I've been looking up the recipe, pricing things up and trying to locate everything so when I'm ready I can have it all arrive at the same time.
    All the measurements are imperial and mean very little to me. Therefore I've converted it to metric for those in the rest of the world haha.
    I'll list the direct conversion and the rounded up version also
    Remember with Organics it doesn't need to be 100% accurate, you're not baking a cake haha, so the rounded recipe should work just as well;

    SubCool's super soil (UK Measure - exact)

    382.2 litres high quality base soil
    22.68kg high quality work castings
    1.134kg fish bone meal
    2.268kg high phosphorus Bat guano
    2.268kg blood meal
    1.134kg bone meal
    0.7litre/700ml oyster shell
    0.7l kelp meal
    0.7l alfalfa meal
    0.177l/177ml Epsom salt
    0.237l/237ml Dolomite lime
    0.473l/473ml Azomite
    2tbs powdered humic acid

    SubCool's super soil (UK measure - rounded)

    400 litres high quality base soil
    23kg high quality work castings
    1.2kg fish bone meal
    2.5kg high phosphorus Bay guano
    2.5kg blood meal
    1.2kg bone meal
    0.7litre/700ml oyster shell
    0.7l kelp meal
    0.7l alfalfa meal
    0.2l Epsom salt
    0.25l Dolomite lime
    0.5l Azomite
    2tbs powdered humic acid



    For the record, this is not my recipe, it's an old recipe from Subcool which has been modified by sub and others over the years. When using this soil, fill pots 1/3 to 1/2 full with super soil (can use 3/4 for super heavy feeders but always test on lower amounts first) . Top with a Standard light mix and then just add water until the end. Teas can be added if yellowing occurs earlier than you'd like.
    Never put plants directly into super soil, the roots will find it and use the nutes as required

    You'll need a large area to mix all of that

    You're not wrong, I mixed; 100l compost, 50l coco and 50l perlite a couple days ago and took a good chunk of my garage floor, had to keep sweeping it back together, needed a bigger space, even for that.
    It is very tiring too, mixing those 200l really took it out of me. I'm running biobizz for now until I'm ready to invest in this mix.
    I'll put the smaller batches up for you too guys, you can do just one bag equivalent and I've got it book marked somewhere

    Thanks for taking the time to round it up to UK measurements etc..

    Smaller batch numbers would be great

    Forgot to say;
    After thorough mixing, wet the soil
    soil needs to be put into bins with lids on and either cooked in the sun for at least 30 days
    Otherwise it should be left for 60-90 days to mature
    Once cooked/matured, it will need another mix

    I'm going to give it a go as it produces some incredible results by what I've seen and by all accounts produces some of the best smelling and tasting smoke.
    It's the 'just add water' side that I'm really looking for, if I get good results and don't need to spend time mixing nutes, then I'm happy. I'm also aiming for perpetual harvest on mixed strains that'll be varying a lot, so the ease is doubled but I appreciate your input.
    I'll be doing a diary, in a few months haha and will link here when I start it, we'll be able to compare then
    What mix are you using yourself?

    Hi mate I would use a
    Peat alternative, my preferred would be Canadian sphagnum Pete Moss, you can use WELL rinsed coco too.
    Aeration 50/50 rice hulls and perlite
    50/50 bio char compost and earth worm castings from the worm bin
    Inputs are All per cublic foot of soil

    1 cup neem meal
    1 cup kelp meal(ascophyllum nodosum)
    1 cup crab/ crustacean meal
    1 cup malted Barley powder(enzymes)

    2 cups volcanic rock dust
    1 cup gypsum
    1 cup oyster shell powder
    Humic ag6
    I would inoculate a first soil mix with some kind of mycorrhizae

    Do you let your soil 'cook' or are you mixing and using straight away?

    I agree with redisiel, mostly because a lot of the listed ingredients are very hard to find where I live but I do really appreciate the time and effort you put into sharing all this with us and putting all those breakdowns for smaller volumes up

    I use it pretty much straight away mate and on another note I wouldn’t be putting any salts in my soils,
    if you do a bit more reading you’ll see there’s no need for all them additives, also you’ll find a lot of unwanted elements in your canna, azomite has high amounts of heavy metals, bat guano is unsustainable and contains certain things I don’t like but good luck with it mate

    So you add no nutes once the grow is underway?

    That is correct yes, the idea with super soil is that you have all the nutrients in the soil already and the plant takes as required, the soil comes alive and the plant literally tells it what it wants through the root system.
    You can add sucanat on day 30 and 45 for an extra boost but you can just run super soil from veg to finish

    If you find plants yellowing early, you can top dress with super soil

    Im going to try filling a pot half way with an amended mix, and the top half a potting mix to see how it goes with an auto. That's mephistos suggestion. I'll be a guinea pig
