New Grower Biobizz Light Mix - perlite recommended?

[zombiedeath]

I am starting a soil grow in 'Biobizz Light Mix' and am considering adding Perlite in at 25% [weighted towards the bottom of the pots]. I am going to soil germinate and will attend to nutrients as required. Any thoughts?

I'm not familiar with biobizz soil,but almost everybody adds some perlite to their mix being ffof or promix or whatever.It helps retain water an makes the mix more airy so the soil doesn't pack down.Unless your soil has alot of perlite already,it wont hurt to add 25 or35% perlite to the mix.

Thanks - its Dutch Organic compost and I think it does not contain perlite in the seedling mix I am going to buy.
