how much to apply 30gal of soil mix..

hey guys am about to mix 30gals of native soil,i have with me chicken compost,dolomite lime,azomite,perlite,epson salts.

how much of each do i need to apply for this mix of 30gal,and whats the best apparatus to measure??

thanks for your patients & time.

ok buddy mixing your own is little hard .................i tried this and my mix was way off i had red stems/veins tho out the whole grow
perlight u are looking at about 30 to 40% mix so 10 lbs of perlite

your best bet is going to be to fallow this

personally i would order myself like 20 gallons of Fox farms ocean forest and 10 gallons of the light warrior mix those 2 up and call it a day ( i am using ocean forest and blackgold mixed this time and loving the results i have a 17 day old female auto with branches if it is anything like my last grow i am happy happy happy )

ok kool got some potting soil instead
