What should I put my plants in next?

[Ghawdex]

Hello all,

My plants are starting to get a bit bigger now and will need bigger pots to be placed in.

They are all indoors as of right now, as the weather is still iffy here, and probably will be until the end of April.

I plan on putting them in a gallon pot, but I am unsure of what to plant them IN, as in what kind of soil/mixture to use. I have been told not to buy the 'brand' name 'junk' and the local nurseries still don't have anything in yet, was told in a week or two.

Anyways, what kind of mixture should I be looking for? I will eventually be putting my plants in a raised plant bed, once the weather is proper.

Thanks!
