The counter calculators, online.
Two sums we run over the counter every week — how hard your air is working on your plants, and how much air your room actually needs to move. No signup, nothing collected.
How hard is your air working?
Temperature and humidity pull water through your plants together — this number (VPD) says whether they're coasting, cruising or struggling. Set your room's readings.
An infrared thermometer reads leaf temperature in a second — we stock them.
The sweet spot for healthy vegetative growth in most crops.
How much air does your room need?
Under-sized extraction is the most common mistake we see — especially once summer hits. Enter your space and we'll estimate the airflow your exhaust needs to move.
Room volume 2.9 m³.
A guide, not gospel — long duct runs, bends and summer heat shift the answer. The gear that moves these numbers lives here, and the counter does the fine-tuning.
