Events at Matt's Hydroponics

What's on at the stores

Everything we run is free. Classes, Free Clone Fridays, and whatever else we put on through the year — it all shows up here. Tap any event to open its details: what it is, who is running it, who will be there, where it is, and a link to the full page.

Every week, both stores

  • Free Clone Fridays — every Friday during store hours. Clones come from The Clone Foundry, our partner, so what is on the bench is whatever they brought in that day. How it works →
  • Grow classes — every Saturday, 11 AM to 1 PM, free. The Master Class series is four classes following a grow from start to finish, running in rotation, so you can join on any week and have all four inside a month. Pizza afterwards. Full syllabus and RSVP →
  • Mushroom class — once a month, free. Substrate and spawn, sterile technique, fruiting conditions, harvest. The next date goes on the calendar below as soon as it is set.
  • Meet With Matt — a free 30-minute grow consultation, booked whenever suits you rather than on a fixed date. Request a time →

Our big days

We used to run a seed vendor showcase every month. We are swapping that for a handful of much bigger days a year — more vendors, better deals, and a proper reason to come down and hang out.

  • Sunday, December 20, 2026 — Customer Appreciation Christmas Party & Seed Sale. Seed vendors, a few of our other vendors, and deals worth filling a stocking with.
  • Sunday, April 18, 2027 — 420 Bash. Our biggest sale day of the year, a full slate of vendors, and pizza.
  • Sunday, October 3, 2027 — Croptober Customer Appreciation & Harvest Day. Seed vendors, speakers, and everything you need to finish and put up a crop.

All three are at the Webster store, 11 AM to 3 PM, free to walk in. A summer date is still to come.

Looking for events beyond our stores?

We also keep a community events calendar — cannabis and cultivation events across Massachusetts, Connecticut, Rhode Island and Maine, with a link through to each one.

Running an event we should list?

If you are putting on something growers in the area should know about, tell us and we will put it on the community calendar. Call 508-461-5850 or send us a message with the date, the venue, who is running it and a link.
