Glad to know you’re getting the information you need! That’s correct, a majority of the biomass on the market right now contains seeds. If you wanted to get super picky about it, you could have a grass seed cleaning facility clear your batch or purchase the equipment yourself. Try it this year and see for yourself which works best for your circumstances. That’s a good bit of acreage to harvest with little experience. Be careful. I’m not exaggerating when I say harvest will be MUCH harder than you probably imagine.
