fox farm question

I know this is probably a stupid question, but here goes. Is there just one type of fox farm big bloom. Or are there different ones for soil and hydro. I'm using soil. If there are more than one type can they be substituted.

I'm also a newbie starting with soil first...and using all FF products. Any FF tips and info would be appreciated.

FF= Good. Use any of there products.

i believe only grow big has a separate hydro/soil solutions....you can use the hydro in both but you cant use the soil in hydro.....
