I have just bought a Strawberry Tub. In the instructions under the heading
Compost it make a point regarding the composition of the compost being very
important. It says" The mixture should consist of two thirds by one third
of perlite(20 litres) or coarse grit(20 litres/25kg). There should be no
deviation from this mixture otherwise there could be plant failures"

Can anyone please explain to me what this means. I understand that the Tub
hold 80 litres of compost/

Many thanks in advance

2/3 of compost and 1/3 perlite or grit.
80x2/3 =53L of compost
80x1/3 =27L of perlite or grit.
That seems a reasonable mix but it is not critical to the nearest litre.
