Who this case is for
If you're going through 50-packs faster than you'd like to reorder them, this is the same bag without the repeat checkout. The 3.0 mil film is built to take aggressive sealing and repeated handling through filling, sterilizing and incubation without micro-tears, and it stays pliable after a sterilization cycle instead of stiffening.
Not sure yet? The 50-pack is the identical bag in a smaller commitment.
How to run a grain bag
- Fill with hydrated, drained grain, keeping the filter patch clear of wet grain.
- Fold the top over and clip it — do not heat-seal before sterilizing, since the bag needs to vent.
- Pressure sterilize, typically 90 minutes to 2 hours at 15 psi. Keep bags off the bottom of the pot and away from direct element contact.
- Cool completely to room temperature before inoculating. Warm grain kills culture.
- Inoculate through the filter patch with an alcohol-wiped needle, or add a self-healing injection port.
- Break and shake once the grain shows even colonization, then incubate until fully run.

How our spawn bags compare
We stock both Unicorn and Blue Myco. Here are the filtered grain bags side by side — the specs, so you can pick on the numbers that matter to your process.
| Bag | Size | Thickness | Filter | Pack |
|---|---|---|---|---|
| Blue Myco Large 3T (this bag) | 8" x 5" x 19" | 3.0 mil (80µm) | 0.2 micron, 1.5" x 1.5" | 50 or 800 |
| Blue Myco Medium 10T | 5" x 4" x 19" | 3.3 mil (85µm) | 0.22 micron, 1.5" x 1.5" | 100 |
| Blue Myco XLS-T | 10" x 5.5" x 24" | 3.3 mil (85µm) | 0.22 micron, 2" x 4" | 50 |
| Unicorn Large 3T | 8" x 5" x 19" | 2.2 mil | 0.2 micron, 1.5" x 1.5" | 50 |
| Unicorn Medium 10T | 5" x 4" x 18" | 3.0 mil | 0.2 micron, 1.5" x 1.5" | 50 or 1,000 |
On the T numbers: 3T and 10T are bag-type designations, not thicknesses. In our catalog 3T is the large 8" x 5" x 19" format and 10T is the medium 5" x 4" format. Check the thickness column above rather than reading it off the name.
Frequently asked questions
Is this the same bag as the 50-pack?
Yes, identical bag and identical filter. The only difference is the quantity and the price per bag.
How should I store a case of bags?
Keep them sealed in the case, indoors, out of direct sunlight and away from dust. The bags are not sterile until you sterilize them, but clean dry storage keeps the filter patches free of debris before use.
Can I pressure sterilize these bags?
Yes, that is what they are built for. The polypropylene stays flexible through the cycle rather than stiffening. Keep bags off the bottom of the pot and away from direct contact with the heating element, and fold the top rather than sealing it so the bag can vent.
Can I use these for bulk substrate instead of grain?
Yes. The 3T format is commonly used for both grain spawn and substrate. If you intend to fruit directly out of the bag, a double patch fruiting bag with 0.5 micron filters moves more air and is the better choice.
Should I buy Unicorn or Blue Myco?
We carry both and use both. Unicorn is made in the USA by the company that invented the filter patch bag, and it is the bag most growers are used to. Blue Myco is the line we run in our own lab. The comparison table above lays out the sizes, thicknesses and filter ratings so you can decide on the specs rather than the branding.
