Can I use the dry start method to create a carpet with only the flourite substrate? ?

[gikas1]

I'm starting a new tank and I'm planning to make a carpet out of Hemiamthus Callitrichoides... I heard online that the dry start method is a good way to get a carpet going but I read that you need a nutrient rich soil to do it... Can adding some liquid fertilisers(spraying them maybe?) achieve the same result or it would be pointless?

Many thanks in advance for any advice!!
