Blue Oyster Mushroom Harvest
★★★★★
“Bountiful First Flush!”
“Picked up two spray-and-grow oyster kits directly at the Fourth Plain showroom. The staff gave great humidity advice, and within 9 days I harvested over 2 lbs of fresh clusters! Exceptional local resource.”
Lion's Mane Harvest
★★★★★
“Dr. Myc Additives Are Game-Changers”
“I was battling contamination in my Lion's Mane tubs until using Dr. Myc TrichEVICT from Fern Prairie. Mixed it during spawning with their sterile bulk substrate—zero green mold and massive secondary flushes.”
Sterile Flow Hood & Monotub

“Midwest Monotub & Grain Perfection”
“Top-shelf equipment from Midwest Grow Kits delivered quickly with clear instructions. The 5-grain spawn colonized vigorously without any stall. Having local in-store pickup for replacement filters is a huge plus.”
