Capacity & Chambers Needed Calculator
Capacity planning answers a simple question: how many fruiting chambers do you need to hit your production target? This calculator computes blocks per chamber from shelf area and block footprint, cycles per year from your cycle length, and the number of chambers required for your target annual output — a block calculator and production-rate calculator for sizing a grow before you commit to it.
Formula blocksPerChamber = (shelfArea / blockFootprint) × shelves · cyclesPerYear = 365 / cycleDays · chambersNeeded = ceil(targetAnnual / (blocksPerChamber × cyclesPerYear))
