From a single tent to a commercial facility.

01 · Plants

Every plant gets a life story.

Seed vault, germination, nursery, veg, flower, harvest, dry and cure — one continuous record per plant. Feedings, training, photos, observations and scores all land on its timeline, so you always know what happened and when.

02 · Environment

Your room, not a zip code.

Temperature, humidity, VPD, light and weather from the sensors actually in your space, per zone, with history you can read in a glance. Know when a room drifts before your plants tell you.

03 · Water

Water with a reason.

Each plant's own soil probe shows when it's actually dry, so you water the plant that needs it — not the whole row. Valve control is next: confirm-before-water first, then automatic schedules once you trust them.

04 · Genetics

Pick keepers on evidence.

Track crosses, lineage and clones. Score every pheno on the traits you care about and compare across runs, so the plant you keep is the one the data backs.

Commercial operations · private beta

Your whole operation.
One command center.

Plants, growing spaces, connected equipment and the people doing the work. Keep the grow record and the daily operation in the same system.

Meet Kai · live in the beta

Tell Kai your day.
Kai does the paperwork.

Kai is the assistant inside Monster Command. It works from your plants, your journal and your seed stash — so its answers are about your grow, not the internet's.

  • Talk your day. Put the whole day in one message. Kai splits it into entries for the right plants — fix anything, then log them all in one tap.
  • Log as you go. "Watered 08, about a quart" lands in your journal, on the right plant.
  • Seed to pot. Add packs to your stash, record taproots, move sprouts to the nursery and transplant them to pots. Kai asks before it moves anything.
  • Answers with sources. Grow questions draw on a curated grow library and live research papers, with citations you can check.

Kai comes with every plan, including free Scout. Chat is text today — your phone's dictation works fine.

Devices

Keep your hardware.
Get one source of truth.

Brand-neutral by design. Your weather station, soil probes and climate controller push to Monster Command, or we pull from their cloud — and readings land where they belong: on the plant, or the room it grows in.

Privacy

Your grow is your vault.

What you grow, how you grow it and what it yields is yours. Monster Command is built so that stays true.

Never sold

We don't sell your data or share it with advertisers. Your records exist to run your grow, full stop.

Walled off by account

Every account is kept separate from every other. Your team sees only what you grant them.

Your gear's keys stay locked

Device logins are stored encrypted and used only to fetch your readings. Or connect a station by push and share no password at all.

Questions

Straight answers.

Who is Monster Command for?

Anyone growing where it's legal to grow — from a single tent at home to multi-room and outdoor operations, breeders and research teams. The free plan covers a small personal grow with every feature turned on.

Do I need special hardware?

No. You can run Monster Command entirely by hand and add devices later. When you do, it connects to gear you may already own — Ecowitt sensors and other weather stations, AC Infinity controllers, and Home Assistant — with cameras, water timers and smart plugs next.

Is Kai included?

Yes. Kai comes with every plan, including free Scout. It logs your day, walks your seeds from stash to pot, and answers grow questions with sources. Chat is text for now.

Is it an app I download?

It runs in your browser and installs to your phone's home screen like an app — no app store required. It's designed phone-first and works on desktop too.

What happens to my data?

It stays yours. We don't sell it, each account is walled off from every other, and logins for your gear are stored encrypted.

How do I get in?

Monster Command is in private beta, and it's invite-only for now. If you've been invited, create your account with the email address you were invited with — you'll start on Scout, free. If you haven't been invited yet, check back here as the beta opens up.
