Buildasoil recipe. Opinions?

Hello! I’m interested in coots recipe. I’m running no till indoors in 25 gallon fabric pots. They have three recipes based off of Coots recipes. Since I’ll be sourcing local compost which is crumbly, light and texture like coffee grinds(composted wood, bark fines). Through searching the web I believe that composted wood are naturally really high in potassium which could cause imbalance and prohibiting the growth of mycorrizhal fungi. So my train of thought is to use the recipe I’ve posted and top dress if deficiencies occur. The second recipe is much lighter in amendments and the base soil mix is different from the original coots recipe. Also most likely going to add the full amount of basalt(2 cups per cubic feet), add oyster flour(1 cup per cubic feet), and gypsum(1 cup per cubic feet). Possibly thinking of reducing the peat and adding a bit more aeration and compost. What’s your thoughts?? Thanks!

Here’s the link

I just build my own but this looks decent.

I use a variation of coot's mix. Done it with worm casings, and with compost separately.
Be careful with the amendments if you are using good compost. Easier to re amend than it is to correct too much

Does anyone know why the second recipe doesn’t call for oyster flour or any type of lime?

Maybe;

Some bros have Hard Water with tons of dissolved calcium (and a "high" pH), and a low calcium (low pH) soil works better with the high calcium water.

I actually fit in this category, I use well water. I guess I’ll try it out, I wonder if I could top dress if I run into ph issues

@kratos015 was telling me about his soil recipe to deal with hard water/calcium in another thread. Hopefully he'll see this and explain more fully.

Post #4 and #11 have some info.

Need a little help guys

Running my normal biobizz reg I’ve used for a long time.just started getting issues tho.my water quality is different at my new location it has a EC of 0.6 and ph is 7.4 to 7.5. bennies Are the only thing I use outside of the biobizz line and my soil is ocean forest.its worked great for years...

Hey, sorry, life has been hectic.

As I always preface this, ensure you know the contents of your well water before committing to this.

But personally, when I removed liming agents and sources of calcium (OSF, Crab Meal, Gypsum) from my soil, I solved my pH problem immediately. Some of the most healthy plants I've ever had.

Only reason I caught this issue was I use fabric pots, and at the bottoms of the fabric pots (which I reuse) were scaling that was reminiscent of the faucets in my house.

I eliminated all Calcium/buffering inputs from my soil and used my well water as a source of Calcium/buffer and problem solved.

This for sure will not be everyone's case, but still worth mentioning IMO. Not everyone lives around limestone like I do, so please be sure to take that into consideration. Due to all the limestone in my location where my well water is sourced from, my water is practically liquid dolomite lime. But, that's just me. Your mileage my vary and such.

You grow outside too right? So you get rainwater sometimes, or am I confused? And how big are the pots you use? Thanks.

Mostly outdoors, yeah. Living in the desert, I rarely get rain unless its monsoon season. I do get rainwater sometimes, but not enough to account for it in a grow. Especially since I don't go out of my way to collect it.

I only use pots for winter outdoor grows. Veg in 5g pots, then put the pots in holes in the ground.

For a normal outdoor, I actually don't use pots and plant straight in the ground. I dig a hole big enough to fit 20g of soil in it, then plant the seed straight into that soil. Roots will eventually grow out of the soil and straight into the dirt.

This way I get a large root mass without having to produce a large amount of soil. Top dressing religiously with my amendment mix and compost gives the plants all they need.
