We will be offering hydro seeding this season. My question is how do you pre-prepare multiple loads. We have a 500 gal. Turbo Turf unit. I see that a lot of folks soak there seed in trash cans. Is this practical/best? Can you prepare multiple cans and take them with you for a days worth of sowing. I'm getting ready to start playing with different methods and thought you guys may be able to help me eliminate the useless ones. Thanks.
