Greenhouse Soil

I've just bought multipurpose compost, top soil and perlite. I also found a box of bonemeal in my shed. What ratios should i mix them together at?

Ill probably be using the soil in about 2 weeks after ive recieved and sprouted my seeds.

Since alot have looked an no one has replied......

Just do a search for soil recipes there are so many different ones. .
Id guess i would go 5O % SOIL, 25% COMPOST, 25 % PERLITE an (also in the bottom of your pots for drainage).
Then mix in the bone meal acordin to its directions.
An any other amendments u decide on.

Thank you for the reply. I only needed a quick answer just like that. Thank you.
