Fifty blocks in a passive container.

Welcome. What kind of mushrooms are you growing now?

Good one. What stage are they in — grain, block, or fruiting?

How many jars or bags are you running per turn?

Two hundred per turn. What's your current fruiting setup look like — tent, shelf, room?

A shipping container. That changes the pressure profile. What's your ventilation setup — passive or active?

Passive in a sealed metal box is a hard constraint. How many fruiting blocks are you running per turn?

Fifty blocks in a passive container. That's a tight oxygen window. What's your current contamination rate look like?

That's the first thing to track. Start logging it — even a rough count per turn. What's your grain spawn source — are you making it or buying it?

Who are you buying from?

That's a good arrangement. Do you know their contamination rate?

That's a gap worth closing. A bad batch from them can lose you a whole turn. What's your fruiting stage look like right now — any blocks pinning or harvesting?

How's the flush looking — weight, density, any signs of stress?
