Groceries are up 24%. Your garden pays in food.

The average U.S. household now spends $6,224 a year on groceries. Harven prices every harvest against real grocery data, so you know by the pound what your bed is actually worth.

24% grocery price increase: USDA ERS, 2025. $6,224 average: BLS Consumer Expenditure Survey, 2024.

No credit card. Works offline. 3 minute setup.

The grocery math

A single tomato plant grows $50 of tomatoes. Most people never count it.

Cherry tomatoes at the store: $5.44/lb. A healthy plant puts out 8 pounds a season. Do the math on a full 4×8 bed and you are looking at $300 to $500 of produce you already grew and never priced.

Harven prices every harvest using real grocery data from the BLS and USDA. You see what your bed is worth, down to the dollar.

What one 4×8 bed grows in a season

$0

Grocery equivalent value of 46 pounds of produce from one well planted 4×8 bed. Priced against BLS retail averages, not a hype number.

Based on 2 cherry tomatoes, 1 roma, 2 bell peppers, basil, lettuce, radish, carrot, green bean. Yields bounded by peer reviewed ceiling (Algert 2016, Dorr 2023).

Food prices are nuts. You grow to save money. Harven proves it with real BLS prices, not vibes.

Where our numbers come from

We don’t make this stuff up.

Every number you see comes from real government data and real science studies. Here’s where.

Our data comes from:

U.S. Department of Agriculture sealUSDA
Bureau of Labor Statistics logoBLS
UCANR
UC Cooperative Extension
Peer reviewed

BLS CPI retail prices

Grocery prices come from the BLS. They update every month. Same agency that tracks inflation.

USDA AMS / ERS

Farm and market price reports from the U.S. Department of Agriculture.

UC Cooperative Extension

81 peer-reviewed studies

Companion pairs, yield ceilings, and Learn articles link directly to their studies inside the app. Pest remedy research backs our recommendations behind the scenes.

Real questions, real answers

Do I need to give you a credit card to start?

No. Free tier is forever. If you upgrade later, it's monthly with a one click cancel.

Does this work without signal in my garden?

Yes. Harven is offline first. Log harvests underground, in the back of the yard, on a plane. It syncs when you reconnect.

Where do your numbers come from?

Prices from the BLS and USDA. Yields from peer reviewed garden trials. Every source is linked in the app. Planting dates from UC Extension. Nothing made up.

What happens if I cancel Pro?

Your data stays. You keep your savings history and 5 plants on the free tier.

What exactly is the $50 / 90 day guarantee?

Use Pro for 90 days. If the total harvest value Harven tracks in your garden doesn't cross $50 in that window, email hello@harven.app and we refund every dollar you paid. Applies to Pro monthly, Pro annual, and Founding. One refund per customer.

Who owns my data?

You do. Everything lives on your device first. Export your whole garden to CSV in one tap. If you ever walk away, take it all with you.

Does Harven know my growing zone?

Yes. Every US zip code maps to a USDA growing zone. Planting dates adjust so you plant at the right week, not a guess.

What can I actually grow in it?

80 plus crops at launch. Tomatoes, peppers, squash, greens, roots, onions, beans, herbs, melons, potatoes, berries, and a few fruit trees. Staples first, oddballs later.

Plant something this week. Know what it's worth by fall.

Takes three minutes to set up your first bed. No card. No email gate. Works offline forever.
