Yield Estimator & Production Planner

Estimate dry yield, a realistic range, key efficiency metrics (g/W, g/ft²), and your harvest timeline. Prefer help? Talk to a Grow Expert.

Yield Estimator

Enter your space, lights, plants, and training. We’ll estimate total dry yield and efficiency. Use realistic entries for best results.

Tip: g/W improves with uniform PPFD, good VPD, and stable CO₂. Training (LST/SCROG) increases canopy efficiency.
Advanced mode: Adjust canopy efficiency and (optionally) DLI proxy inputs.

Frequently Asked Questions

Is this accurate?

It’s a planning tool. Expect a range, not a guarantee. Genetics, environment, and technique drive outcomes.

What is a good grams‑per‑watt (g/W)?

With modern LEDs and a dialed‑in environment, many growers see around 1.0–1.5 g/W; advanced setups can exceed this.

How can I increase yield per ft²?

Improve light uniformity, train for an even canopy, enrich CO₂ if feasible, and maintain optimal VPD by stage.

Does CO₂ always increase yield?

CO₂ enrichment is most effective when light intensity and environmental controls are already optimized.

How do you convert wet to dry weight?

We assume a typical ~4.5:1 wet‑to‑dry reduction for trimmed flower.
