A grow bag is not an instant mushroom. Here is the real timeline, so you can decide whether it fits your space and your patience before you buy.

All-in-one bags. You inject liquid culture through the port, 3 cc for a 2 lb bag, 5 cc for a 4 lb, 10 cc for a 6 lb, then set it somewhere warm and out of the way. The grain turns white over about three weeks. You break it up, mix it through the substrate sealed in underneath, and wait about three more. When the surface is fully colonized you unfold the top and let the bag breathe. Fruit follows in roughly another three weeks. Start to harvest is about two months, and almost all of it is waiting rather than working.

Monotubs. Spread two to three inches of hydrated substrate across the bottom, mix in colonized grain spawn, then cap it with a quarter to half an inch more. Lid stays on with the filters in place, for gas exchange rather than full fresh air. At 70 to 78F the surface is usually white in 10 to 14 days. Keep it warm and dark, out of direct sun. Harvest when the veil under the cap starts to tear away from the stem.

What you supply. Clean liquid culture, a still space to work in, and alcohol wipes. We do not sell cultures or spores and never have, so every bag ships uninoculated. That is also the single biggest variable in whether a grow succeeds. A contaminated culture will fail in a sterile bag just as surely as in a dirty one.
