fire sacrifice

[Guest guest]

I have a question, with regards the fire sacrifice:

 

Do u have to do it at a set time during the day or can u do it at night?

Also where I am it is difficult to get different types of wood as

recommended by shastra is it ok to use other wood?

Is the any resource on the internet where I can get the ingredients

for the fire sacrifice sent to me?

How can I find out which ingredients are for which purpose?

Are there any resources where we can learn different fire sacrifices

with transliterated texts?

How can one learn is there a school where one could learn this?

 

Thank you.
