Reusing indoor soil outdoors

I have about 60 gallons of Roots Organic soil I used for my indoor grows this fall and winter, with 40 more gallons almost ready to dispose of. Can I till this into the outdoor soil? I can imagine it is somewhat hot, but after all of the flushing, I wonder how hot it is? I have some "stuff" called rapid flush, used to remove the salts that build up (although I have never used it).
Last year I used the old soil on my lawn to reseed the grass in various spots and it did well.
Last year I used the Roots Organics, but at $25 a bag (using 30 or so bags) is a huge cost factor in planning my outdoor grow. I like growing outside, but don't want to spend $2,000 on soil mix (last year I got horrible bud rot).
So I have (I am guessing) 10 bags of used soil which would reduce my cost by 1/3.
Any ideas?

Yes till in
It will benefit from being tilled in. Throw in Epsom salts if you like and you use this for foundation planting soil, mulch, etc
Recycling here in my garden is ez
