First time mixing organic super soil , help please

I searched all the different threads in rollitup and didn't see a section for such a question so I hope I'm posting it in the right location .


So here is the recipe I found , and I have everything I need (except pro-mix HP , I'll have that Friday I live in a small county and they had to special order it and I'll be mixing everything then )

The recipe is:
6 parts pro-mix HP(only one I can get)
2 parts EWC
2 parts perlite
2TBSP/gal dolomite lime

Nutes :
1/2 cup blood meal per cubic foot
1 cup bone Meal per cubic foot
1/2 cup kelp meal per cubic foot

I also have high P jamaican bat guano , should I use that instead / substitute it for the bone meal ? I haven't actually picked up the blood meal yet but do have high P guano from a previous grow . Didn't want to buy it until I knew for sure the guano wouldn't be as good a choice .

I've only ever mixed my own soil once , I forget the recipe , was just soil , blood meal, and bone meal and used it on veggies and they grew amazing .

Now my issue is, I only have 20 pounds of EWC and 2 parts in the recipe would be 35 pounds :/ . I paid 56$ for this 20 litre bag and don't have the funds to spend more . Would this 20 litre bag do okay, or should I lessen everything else in the recipe to make the ratios the same as the recipe calls for ?

And my other question is, I mix all the amendments in the soil , moisten it and let it sit for 1-2 weeks right ? Some sites say to put it in a sealed container when doing this , is that necessary or would doing so on a tarp in a shed be okay?

Sorry if this is all total noob questions , I just want to make sure I get this right . Got myself some AK-48's and OG kush auto's and bagseeds, never grown more than a few plants at once so I'm hoping all goes well this year.
I have chemical nutes and couldnof been lazy and just used those with some store bought Mixed soil, but I've read a ton of good things about organic super soil.

RIU members were very helpful in my last post about plant problems I was having , so I'm sure someone will be very helpful for this one too. Thanks in advance guys !

There is a organic section just for this type of thing. My problem with your mix is it mainly pro mix = just peat moss..So it is going to compact even with the perlite witch will likely float to the top, and it hold a lot of water = root problems. The small amount of ewc you have i dont think is going to break the mix up enuff. I would try to source some local compost or even use your natural soil in the mix if it is viable, and add more perlite or whatever aeration..Try to hit a 1:1:1 ratio for your base

And your nute mix only has Nitrogen-Phosphorus, and a little Potassium, The kelp is great but .. your missing calcium, magnesium and a few other micronutrients. The ewc will give you cal,mag but not enuff..this is my mix

10 cuft horse manure compost
10 cuft pro mix bx
10 cuft rice hulls

NUTES - 5 pounds = 15 cups
1cup to 1 cu ft
kelp meal, alfalfa meal, neem meal, fish bone meal, crab meal, gypsum, azomite, And when you mix it it needs to sit for 2-4 weeks keep it moist and turn it maybe once a week. It needs to be covered not air tight but no direct light.

For you i would recommend bio tone starter plus, happy frog bulb food, and epsom salts along with a teaspoon of urea if you are able Mixed 1 cup per cu ft.. This is a all around all in one nute mix that a very good grower here uses. O and bat guano is pretty quick to release so it will need replaced more often bone meals can last years.. Hope i helped

Also i added worms into my pots so they keep my soil aerated and make my nutes easier to be taken by my plants so i have a ewc farm in my pots.

My growing season here is very short (ends in early October ) and from what I'm reading you need to cook your soil for 30-60 days right ?

Can I just buy a soil and add a few additives to it and make a decent soil? That can be ready within about a week?

I have already boughten ewc,
Blood meal , high P guano , kelp meal and dolomite lime .
There is a local grocery store that sells "super soil " do you think that stuff is any good ? Is it something I can buy and just add some guano and blood meal and lime to? Or does it still need to cook.

Sounds like I didn't start early enough if I need to cook and start my own super soil this year . Should of done more research.

I've tried to research the stuff I'm asking and I haven't had luck . I'd really appreciate your input thanks man . Need to figure out something , babies have to go outside in a couple weeks.

30 days minimum longer is better. The premade super soil could be good see what's in it, compare it to
Foxfarm Ocean Forest. if its decent you shouldn't need to add anything expect the ewc and maybe perlite some pemaid soil it pretty hot already . and you don't need to cook it.. also check out the organic section, lots of good ifo their .

Sadly there isn't any ingredients listed on the bag lol :/ I looked everywhere , even googled the brand and found nothing on it .

Maybe I'll pick it up and add some guano and blood meal to it , doesnit need to cook to do so or is that only when your adding compost like EWC ? It's too bad I don't have time to do all the necessary prep, I have unlimited supply to fresh horse poop too lol, my cousin owns a ranch with about 15 horses/donkeys

I also posted in the organic section lastnight but haven't had luck on replies which is why I'm picking your brain a little man, haha I appreciate it

I use Jobe's Organic as a base and add to it. I always use (and have for 20 years) used 1/3 perlite. Good drainage and rapid root growth makes good. Foxfarm sucks and don't use it! It is a scam to sell you expensive bottles of additives on a schedule that cost a small fortune and isn't even organic! I don't have to feed mine anything start to finish. Foxfarm has you feeding right up to harvest which is ridiculous as should never feed a month to 3 weeks prior to harvest and always flush. Friend of mine swears by foxfarm and his stuff tastes like crap and is all brown and his seeds are wacked because Foxfarm screws with the genetics and makes seed shells impossible to pop because so thick. I did a side by side test with Ocean Forest with two White Widow clones and the Ocean Forest had so many deficiencies that had to chop it early..hard to see from pics...one on the left is straight Foxfarm Ocean Forest (with added perlite). Computer harvest pics were on crashed.

And of course Foxfarm Ocean Forest sucks straight because I didn't buy the expensive additive bottles so why would the soil be worth a crap straight!

Where do you purchase this jobes organic?only places I have to purchase from is a local gardening shop, Walmart , loses, the Home Depot and home hardware.
And when you add the additives , do you have to cook the soil? Or do you only do that when your creating your own organic soil base.

My main question is, when you add guano meals lime or anything else to a soil, does that have to sit and cook over time or can it just be mixed in really well and ready to use?

I'm a noob to mixing soil. Just not sure if cooking is only needed when using your own raw organic material / microbes like compost or EWC, or if you have to also do so when adding any additives to a soil

got the Jobe's Organic at Walmart, also Just Natural Organic at Walmart but they sell out early here so if you don't buy it early on they don't seem to reorder. Then I add worm castings, bone meal, etc. plus 1/3 perlite. Here is what they look like. Maybe you can order online and pick up in store. Walmart sells all kinds of stuff now including grow lights...mostly online.

I would stay away from Bat guano myself dolomite lime usually has to sit not sure how long as I use a premixed organic bloom booster for phosphorus instead of lime.

It's what I have these Maui in at 4 1/2 weeks in flower: No feeding just a late flower flush!

Awesome man those buds look insane for 4 and a 1/2 weeks :O

I'm from Canada, and I went to my local Walmart and all I could find for organic potting soil was miracle grow organic. Heard good things on grasscity about it, but also some bad things , heard people having issues of fungus gnats using this MG organic soil , and it even states in they're instructions that it is not made for containers .

Maybe I should just grab some black earth, mix in my own perlite and blood/bone meal and lime , and feed it teas with EWC/guano .

Does that sound like a decent game plan?

I have a bale of pro-mix HPthat I may use too , some people are telling me it isn't so great because it's peat based . What do you think of if mixing some ammendements in it?

Sadly Don't have time to add compost or anything that needs to cook , very short growing seasons here , ends the start of October

You can use pretty much any decent organic soil as a base and then add in compost and mineral inputs. Many times you'll find bagged organic soil from a home store tends to be a bit too heavy and compacted as it is intended for outdoor raised beds so you'll want to add perlite and coco or something for aeration and good drainage.
Just throwing a bunch of stuff together is not what makes a soil super; super soil means there is a high level of microbial activity. In my exp it takes a few recycles before your mix reaches the coveted supernatural status.
Cook time is only needed to normalize the ph as adding a bunch of organic materials and minerals all at once can drop the ph of the soil down a bit too acidic. Letting it set for 30 days eliminates the need to bother checking ph and by checking I mean with a good quality digital soil probe. You can add compost without needing any cook time but minerals like D-lime or azomite need time to be broken down by microbes in order to become available for absorbtion.
If you want to get started right away there is no reason you can't use a lightly amended bagged soil to begin with and supplement with a liquid fish and/or seaweed fertilizer like Neptunes harvest weekly. Brew up an aerated compost tea every few weeks to maintain microbial activity. If you want to give your plants a boost say just before bloom phase you can just push in a Jobes organic spike or 2 which feeds your plants for 8 weeks.
