'm trying to to make my first supersoil. For 50l of used mix of 3 parts of peat moss, 3 parts vermicompost 2 parts perlite and 1 part vermiculite. I'm using a bag of lurpe earth vibes, 400g kelp, 2,5kg bokashi seaweed, 600g volcanic basalt, 70g of dolomite, 150g palm tree ash and 2 handfulls of veg perl. Going to fill the bottom of 4 bags os 25l and let some to mix with the rest of my base soil and fill up the rest. What do you think of this mix?

That bag of lurpe earth vibes has biochar in it. But yes, I would add more quality charged bio char.

Perlite is inorganic does not break down I would never use it in a supersoil, much better to completely replace the perlite for something like rice hulls that do break down that your plants and the microbes in the soil will love.

I never recommended perlite. Why you quoting me? i was just pointing out that theres bio char in what hes using already.
In a No-till situation, aeration that does not break down is ideal. The issue with perlite is that it floats to the top over time. This is NOT ideal for a No till situation. It should be fine for ROLS. Especially if you run short cycles. Lava rocks are also a good substitute. Adds minerals to your mix.
The problem with rice hulls is you must boil them and when they break down, you must re amend with more aeration which requires tilling the soil.

I use lava rock and perlite in my rols. I don't think there is a better bang for your buck than lava rock 
Whatever you use, use more! I started out similar to your mix ratio. A year later and I'm closer to 30% peat, 30% compost/ewc, 40% aeration.
If I was to make another batch of soil, I'd run the same 3/3/4 ratio, but I'd just throw a couple bags of Dr Earth dry ammendments and basalt in the mix, and be done. Simple and effective

I was but I needed some phospher so I mix 70g of seabird guano and some amino acids (L form and from organic source) to help the uptake of calcium. Trying not to put Neem. Want to let micro life balance it self
Biochar it's good already as some accumulation from past use
Like perlite it doesn't go a way. Yes it comes to the top but just the first layer. The compaction doesn't let it move a lot
Like the lava rock idiea
Don't think so. Kelp and seaweed bokashi it's a must have in my soil. Like the idea of having a 110% soil . But a get you reused soil needs more areation to compensating the peat moss compactionI use lava rock and perlite in my rols. I don't think there is a better bang for your buck than lava rock
