I want to build my own soil. I bought some peat moss today with cocoa chips , I have to get some perlite today. 1st Can I use those ingredients to make good soil ? If so what’s the ratio of mixture?
Adding those will assist in drainage, but not really add anything NPK wise.
If you are growing outdoor, you can mix those things with fertile farm soils and compost, possibly some well rotted manure and a cup of lime… and make a real nice soil. Ideally I make stuff up like that in the fall and let it stand over winter, but you could do a hot mix and be ok too.
Conversely, if this is for indoor, you will want to follow a suoer soil recipe and not use any outdoor soil products.
I agree with cannabian you need at least some compost unless you plan on feeding them salt based nutes from day 1 like hellraiser ,I would think a ratio of roughly 50% peat 30% compost and 20% chips would get you going for the first 2-3 weeks then start your fert regiment
Do you want a medium to grow plants in or do you want a medium to feed and support the plants. Very different approaches.
The first is pretty straight forward. What substrate do you want to use, what drainage characteristic do you want, and the nutrient regime to match the first two. The latter can run the range to very complex soil building with many different possible routes or, on the other end, open a bag of this and that, follow prescribed formulas that have been tested and proven.
You’ve got what you need to start putting together a soilless mix.
I agree that anything you’re mixing yourself you wanna plan to let it mellow out for 6 weeks or more before you use it.
All winter I have been dumping my used soil and run off water in the backyard where I will be putting my out door plants this summer. Hoping it charges the soil in my garden.
Not much in that used soil that’s gonna charge anything up… it’s used. Till in various poops with that used soil and you’ll have something good. Earthworm castings, composted cow manure and a few good scoops of composted chicken poo will do ya right
Was all miracle grow soil. Figured there’s gotta be something left to it. And with using miracle grow I figure there’s also gotta be some in the runoff. Better in the garden than down the drain. Just less top soil I gotta get to fill in the removed grass.
There was a member of the forum that made his own soil. A lot of people have used it with success. If you look up garrigans soil recipe you can find it pretty easy. Mr Garrigan recently died from Cancer. He is greatly missed. To find his recipe, up at the top there is a magnifying glass. Click on it and enter “Garrigan” and you will see the thread with his recipe, and there’s another thread with a tea recipe too. Good luck! Peace…

Do you use this recipe? I may have to switch. My two tries with build a soils’ recipes are not producing for me. Peace…
This is the mix that I have used the last couple of times. When transplanting into it I use some starter mix to provide a transition buffer to this “hot” mix. I started using advanced nutrients Iguana organic line. I still started pretty early with it despite the ability of the soil to carry them longer. At transplant to 5 gallon bags I fed at 600-700 ppm and increased to 800-850 in early flower and stayed in that range through out the grow.
Why no composted manure indoors? I’m currently using 60% composted manure mixed with 20% perlite 10% vermiculite and 10% peat, there’s peat in the bags of composted manure too.
I’m getting good quality and good yields, but I’ve had some bumps on the road too. I’m up for a change if it will improve my results.
So why are outdoor products not recommended for indoor?
Well primarily because of bugs like fungus gnats… and other critters that might be in the mix. I really would rather not have to worry about bugs indoors. That way when I transfer my
when the light hours are good… the plants have a good start with no setbacks. They dont mind peat based soiless mix for the first while… that plug essentially is inert… void of any nutrients by the time I plant em in May. Then they go into straight organic soil and only organic foods from May to Nov…that gives the plants more than enough time to go from synthetically made nutrients to being fully organic. I dont do synthetic weed!
