2 qt bag of semi-hydro substrate consisting of 5050 chunky perlite & fluval stratum. Perlite has been washed, rinsed & strained to remove as much dust and fine particles which can cause compaction, leading to root suffocation. Perlite is then dried in high heat to disinfect. Fluval stratum is then added and all ingredients are sifted one more time to remove dust and fine particles before being bagged for customer distribution.

*Ingredients: Fluval Stratum & chunky perlite
