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 44 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 1 spawn bag (or two 32 oz grain jars) with 7.5 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: one spawn bag (2.25–2.5 lb) to 7.5 lb of substrate is roughly 1:3 grain to substrate. Go heavier on spawn if you want faster colonization.
Restock and upgradeReplacement medium pre-cut liners and 2.5" filter disks, and the Canopy Cutter for harvesting. Other sizes: Small 28Q cube | Large 66Q.
1 spawn bag (or two 32 oz grain jars) with 7.5 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.
Overall awesome tubs. They work perfect and are not only superior but more affordable than competitors websites that I have tried.
Got it quick...and about a week later they were pinning. The week after that I was eating them.
High Quality products with an ever helpful, extremely reliable and helpful team, we could not be more pleased. We recommend Midwest Organics to any one serious about growing the right way.
I ordered two monotubs from different sellers on the same day. If you wnat your items fast order from Midwest... It arrived pronto! teh other tub from competitor i orderd is still not here weeks later.
I really love the design of these. I just bought my second. The black base is nice to help keep light from entering the sides and causing fruits to grow in to the side of the tub. The tall lid is also great because it allows you to easily access your mushrooms when harvesting. No reaching down in to a deep 56q bin to try and reach your delicate little specimens.
