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. Book a slot →
Upcoming dates
The next few weeks of classes and clone Fridays are below. One-off events — vendor days, demos, open houses — get added here as they are booked.
