Calculate bags, volume, and substrate weight for your crop and growing system
Step 1 — Select Your Crop
Step 2 — Growing System
🪴
Open Top Grow Bag
🌱
Hydroponic Growbag Slab
🏗️
Substrate Trough
Step 3 — Polyhouse Details
Major Aisle Deduction (optional)
Deduct the area of any major walkways or aisles running through the polyhouse. For ginger/turmeric, inter-cluster walk paths are already included in your row spacing — only enter major aisles here.
Enter your trough dimensions and total number of troughs. Substrate volume is calculated at 85% fill factor — leaving headspace for irrigation and drainage.
