Two compact Grower's Select 28 quart cube monotubs in one box. Run two strains side by side, stagger your harvests, or keep one tub fruiting while the next one colonizes. Each tub has extra-thick polypropylene walls, a reinforced bottom, 4 pre-drilled air exchange holes, adhesive filter disks, hole plugs and a pre-cut liner. Each 12" cube takes one grain jar or half a spawn bag, so a single spawn bag split between the two tubs is a common setup. 2 x 28 qtVolume 12" cubeEach tub 4 per...

The Grower's Select 28Q is a compact 12" cube monotub, molded for mushrooms rather than drilled out of a storage tote. Extra-thick polypropylene walls and a reinforced bottom keep it from flexing, and it comes ready to load with 4 pre-drilled air exchange holes, adhesive filter disks, hole plugs and a pre-cut liner. It's the tub for testing a new strain before you commit a big tub to it, using up an extra jar or half bag of spawn, or growing in a space where a wide tub won't fit. 28 qtVolume...

The Portable Humidity Tent is a 12" x 12" x 24" cover for one ready-to-fruit block or grow kit. It holds moisture around the block so you mist less, and its 16 vent holes let you set the airflow with clear stickers and filter disks. It's the simplest upgrade for kits fruiting in dry winter air. 12" x 12" x 24"Size 4 milPoly 16Vent holes 6 x 1.5"Filter disks 10Clear stickers Why use a humidity tent Mist less The tent traps moisture around the block, so the surface stays humid between mistings...

Agar slants are the long-term home for your best cultures. Each slant is a pre-poured test tube of malt extract agar set at an angle: transfer a clean piece of mycelium, let it establish, then refrigerate it. A colonized slant keeps a culture viable for up to 12 months, far longer than an agar plate, so your master cultures stay safe without constant replating. Every tube is a 15 mL polypropylene test tube of agar, light malt extract, potato dextrose and locust bean gum, pressure-sterilized,...
