Help with my spawn math

I want to make a shoebox. It's 6 liters (little over a quart). I'm not supposed to fill it to the brim, right? So I need 3 liters of spawn and coir (plus more coir for casing)
I think I've read here that the spawn to coir ratio should be 1:4. So it's .6 liters of spawn an 2.4 liters of coir (that'd br like 540 g of dry coir, if I'm not mistaken). And, since rye doubles in volume, I'd need .3 liters of rye.
Plus of course, I don't know, 200g of coir for casing.
Does that check out?

Youre way overthinking it. Stick to 1 quart of spawn for shoeboxes. Prep your coir then add anywhere from 1 to 6 quarts. Id stick to 2 quarts if I were you. Mix it up, compress with a rubber grout float or something similar. Put the lid on and forget about it.
Btw 540 g of dry coir is about 10 quarts. Way too much. 650 g is a brick and will normally make 12 quarts.

But what's wrong with them? They sound like good training for bigger monotubs and allow you to try more varieties, no?

Lc needs to be tested before being put to grain. If youre new then learn agar first before messing with lc.

Man, I would have sworn that I read five minutes ago that 1g of coir equals 4.44 ml at field capacity, but I can't find the thread
Thanks for the heads up!

Last time I checked my skill level was at minus 56. I'll check the basic bucket Tek but already got the shoeboxes, the rye (I live in a 3 million people metro area and took me two weeks to find a shop that carried the magic stuff!) and some mycelium in agar that's begging me to inoculate it.
Is the basic bucket Tek considered more noob friendly than shoeboxes?

I´m sure it´s 4,3492 ml at field capacity. Damn mate, don´t make brains about these numbers. All brick brands behave different in expansion and whatever. The brand i use barely needs 3 quarts of water to a brick of 650gr, it´s more like 2,75 qts. I also don´t care for the exact volume, as i compress the sub a bit, i always want to have enough coir ready at hand. If you really need it just for one single shoebox, take about a third from the brick. If shoeboxes, i like them this way, three in a row in a big tub makes great microclimate.
Besides that you can store leftovers, if you prepped too much

Just a suggestion: if you were aiming at only .6 liter of spawn: make more spawn jars than just for the .6 liter of spawn. Better a bit more jars to pick in case of contamination.
Also maybe an idea to use weight when you want to be specific on ratios. Measuring volume exact is tuff, unless what you're measuring fills all air pockets and has a flat surface. Like liquid fills all air pockets and is flat. Rye is tuff to volume measure. But it also is not a solid and strict science. But if you want to make notes for a next time, better to switch to (also) weights.
Further I think you math seems fine. 
Regarding filling to the brim: depends on your 'shoebox'. I remember I've read long time ago that coir substrate should not be more than 10cm thick. But I can be faulty in that memory. In reality I think it is not per se about 10cm, but about pressure in/on the substrate. PS: I myself aim at 4-7 cm (including the pseudo layer). It kind of depends on how much spawn I have. And with 7 cm, then there are still a few centimeters left for air and the holes.
