How much Perlite & Vermiculite for a 5 gal smart pots?

[SiamBuds]

Hey, local store sells nice soil from NL, its with nutrients that lasts weeks, its good price and big bags, so decided to use that. Will order Perlite & Vermiculite, and that should be all it needs.

Question, how much Perlite vs Vermiculite do I need to add to soil for 5 gal smart pots.
How do I measure that.

They sell 4L bags of it.

so 4L for how many pots?

thx

I use about 1/4 to 1/3, depending on what else I put in and if I'm adding to new soil or re amending used soil.

I don't use vermiculite in my super soil but I do use perlite at a rate of 20ltr into 70ltr of soil. About a 1/4 to 1/3 seem to be the common ratio.

Just remember, no nutrients in perlite so you going to have to start using nutes from the start.

I use 30% perlite by volume, I make sure to pre-soak the perlite in ph'd water before measuring/mixing.

Soil comes with nutrients for 8-12 weeks thats whats it says on it

Its some organic soil from NL, 40L bags and good price, so going with that, best I could find here

I will add CalMag to water in later stage.

i use the 40L bags here in the netherlands, I mix 5l of perlite per 40l bio soil, I dont feed for the 1st 4 weeks at least, if the plant look as if they require food after the 1st 4 weeks I start with half strength nutrient solution and build up as the plants grow. I have never used calmag.

that's what I was responding to about the nutrient thing. but after thinking about it you could mean NOT adding vermiculite..srry.
