Better hay for the barn
Hay steaming, without the hassle
Horse owners steam hay to cut down on dust and mold spores. The trouble is that today's options are either expensive, messy, or a weekend project with no way to know if it worked.
Soaking is a chore
Heavy wet nets, dripping hay, and dirty water to dump every day.
DIY is guesswork
A tote and a wallpaper steamer can work, but you're drilling, sealing, and hoping the middle got hot.
Commercial units cost a lot
Store-bought steamers often run well over $1,000, which is a lot for a one-or-two-horse barn.
How the ready-made version works
Same idea as the DIY build, but it arrives assembled and leak-tested. No tools needed.
Load
Stack hay flakes loosely on the stainless grate.
Fill & plug in
Fill the steamer with water and plug it into a GFCI outlet, or schedule it with the Smart Add-On.
Check the core
The long-stem gauge shows when the center of the hay is hot. Add-On users get a phone alert.
Feed & drain
Feed, open the drain, and rinse the lift-out grate.
Made for the barn you already have
Built by a horse owner who got tired of soaking hay. Whether you keep one horse out back or run a full boarding barn, cleaner hay should be simple.

Built around the four things that matter
Core temperature, not guesswork
A long-stem gauge reaches into the middle of the hay, where it matters most. Probes on the Smart Add-On measure two spots at once.
Wi-Fi tracking
Watch the temperature climb from the house or the truck, get an alert when it's done, and look back at past cycles.
Timers
Schedule steaming so hay is ready at feeding time, and have it shut off on its own.
Easy cleaning
Open the drain, lift out the stainless grate, and rinse. No hidden seams where mold can hide.

Questions
Is the guide really free?
Yes. Enter your email and download it right away. We'll send occasional build tips and news about the ready-made version, and you can unsubscribe anytime.
When will the ready-made version be available?
We're testing prototypes now. A small beta with local barns comes first, then pre-orders for list members. We'll email you before anyone else hears about it.
How much hay does it hold?
Ready-to-Steam is sized for a typical daily ration: several flakes at a time. Exact capacity will be confirmed after testing.
Do I need Wi-Fi?
No. The core temperature gauge works without power or Wi-Fi. The Smart Add-On is optional for phone alerts, history, and schedules.
Is it safe?
The steam generator is a safety-listed unit used as intended, and the cooler itself has no electrical parts. Every Ready-to-Steam unit is leak-tested before it ships. Always use a GFCI outlet and follow the included guide.
Will the DIY Kit work with my cooler?
We'll publish a list of coolers that passed our heat tests. Tell us what you have in the form above and we'll let you know.
Where will you ship?
We plan to start in the US, with local pickup or delivery near our home base and shipping beyond that. Your ZIP code helps us plan.
