A production room is not an enlarged grow tent. Scaling up changes the nature of the problems: what was a detail in one square metre becomes a structural constraint across thirty, and a design mistake is paid for at every cycle for years. This step covers what gets decided before the first piece of equipment is bought.
Start from the usable area, not the total area
The area that counts is not that of your premises, it is the area your plants actually occupy under the lights. Between the two sit the circulation aisles, the work zones, the plant room, the storage of inputs and the drying area. In a hundred square metre unit, the genuinely cultivated area rarely exceeds sixty to seventy.
The first trade-off concerns bench width. A bench accessible from one side only must not exceed the length of your arm, meaning around seventy usable centimetres. Accessible from both sides, it can go to double that. Beyond that, you can no longer reach the middle without climbing onto the bench or crushing plants, and maintenance becomes a chore you keep putting off.
