A mushroom monotub molded for the job, not a storage tote with holes drilled in it. Grower's Select tubs have extra-thick polypropylene walls and a reinforced bottom, so a loaded tub doesn't flex when you move it. The 66 quart tub comes ready to load with pre-drilled air exchange holes, adhesive filter disks, hole plugs and a pre-cut liner.
Extra-dense, extra-thick polypropylene with a reinforced bottom. It holds 200 lb without flexing, so picking up a full tub won't crack the colonized surface.
6 pre-drilled holes take 2.5" adhesive filter disks for fresh air exchange. Plug them during colonization to hold CO2 and humidity, then open up for fruiting.
Filter disks, hole plugs and a pre-cut liner come in the box. No drilling, no measuring, no tote to modify.
Stick a filter disk over each hole and fit the liner. Put the plugs in for colonization.
Mix 2 spawn bags (or three to four 32 oz grain jars) with 10 lb of pasteurized bulk substrate and level the surface.
Keep the lid on and plugs in at 72–76°F, out of light, until the surface is fully colonized.
Pull the plugs, give it 12 hours of light a day and keep humidity up with misting and fanning.
Spawn ratio: two spawn bags (about 5 lb of grain) to 10 lb of substrate is roughly 1:2 grain to substrate, a heavy spawn rate that colonizes fast and resists contamination.
Restock and upgradeReplacement large pre-cut liners and 2.5" filter disks, and the Canopy Cutter for harvesting. Other sizes: Small 28Q cube | Medium 44Q.
2 spawn bags (or three to four 32 oz grain jars) with 10 lb of bulk substrate. That gives a good spawn rate for fast colonization and an even surface for pinning.
No. The 6 air exchange holes are molded and pre-drilled. Stick the included filter disks over them and you're ready.
Plugs restrict airflow during colonization, when mycelium prefers higher CO2 and humidity. Pull them when you switch to fruiting conditions.
Yes. Clean and sanitize it between runs, and use a fresh liner and filter disks. Replacements are sold separately.
Grower's Select tubs are custom molded with thick walls and a reinforced bottom rather than thin storage-tote plastic. They hold 200 lb without flexing, which protects the substrate surface when you move a loaded tub.
All products are the best ones I have ordered never a problem
Comes exactly as described. Very well made and accommodating to what it's supposed to be used for.
Great product for home growers. Better than I could have made myself and much cheaper. Highly recommend.
Not my first purchase. Super nice and very efficient sellers. I’m not usually much a fungus grower, but at least for me times are tough. These people make it much easier.
I liked the old Sterylite mono tubs, but these new Microppose tubs are better. They are sturdy and less brittle that the old ones. The black bottom helps reduce the number of mushrooms that will sprout on the bottom. No complaints… I have nine of them and will continue using them! Great product at a very reasonable price!!! Joe
