To all of our customers — thank you!

The last few years have brought a lot of changes to our industry with new regulations, legislation, and constant shifts in the market. Through all of it, your support has kept us here, growing and adapting instead of shutting our doors. We genuinely appreciate every person who shops local and continues to support small businesses like ours.

Because of that support, we’re expanding and evolving to become more of a true one-stop shop. We’ve added new convenience store items, drinks, snacks, and a larger disposable v**e selection, while also continuing to grow our glass, vaporizer, and headshop inventory with more options and better variety coming in regularly.

We’re committed to keeping the shop stocked, improving the selection, and continuing to bring in products people actually want — all while staying compliant and pushing forward in a changing landscape.

Thank you again for sticking with us and helping keep local business alive. More new products and upgrades are on the way. 👊

Mothers day is right around the corner!

Before you plant a single seed this spring, pick one up and squeeze it between your fingers.

If it's firm and resists pressure, the embryo inside is likely intact. If it crushes hollow or crumbles between your fingertips, that seed was dead before you opened the packet. That took two seconds. Here are three more tests that cost nothing.

🌱 The scratch test:
Take a larger seed — bean, pumpkin, sunflower — and nick the outer coat with your fingernail. White or green underneath means the embryo is alive and holding moisture. Brown or dry and hollow means the seed lost viability long before you found the packet in the back of the drawer. This works on any seed large enough to nick, and it tells you something no printed date ever will.

The sniff test:
Open the packet and breathe in. Healthy seeds smell like almost nothing — faintly earthy, mostly neutral. Seeds with high oil content — sunflower, corn, squash — go rancid as they age. If the packet smells stale, sharp, or off, the oils inside have broken down and germination will be poor.

The paper towel test:
This one settles every argument. Lay ten seeds on a damp paper towel, fold it over, slide it into an unsealed plastic bag, and leave it somewhere warm for seven to ten days. Count the sprouts. Eight or more means the packet is still strong. Five or fewer means it's time to compost the rest and buy fresh.

🪴 Every one of these tests reveals the same truth: viability depends less on the date on the packet and more on how those seeds were stored. A cool, dry, dark spot keeps most varieties alive for years. A hot garage or a humid drawer kills them in a single season. The seed hasn't changed — the environment around it did.

Everything you need is already in the kitchen drawer. 🌿

A black pot in July afternoon sun gets hot enough inside to damage the fine root hairs that absorb water and nutrients.

The plant above ground wilts. You add more water — but the roots can't use it. You blame the sun or the watering schedule. You never look at the pot.

Dark containers absorb heat through the walls and transfer it directly into the soil. The thin plastic of a standard nursery pot — the container most plants come home in — offers almost no buffer. A tomato in a black pot on a south-facing patio in July is sitting in soil far hotter than the air around it.

Dark green and dark brown run only slightly cooler. Not enough difference to matter in peak summer.

White pots reflect most of the incoming light instead of absorbing it. Internal soil temperatures stay dramatically lower — close to air temperature in the same sun. The roots stay functional. The plant performs.

Terracotta falls in the middle and adds a bonus — moisture wicks through the porous clay and evaporates on the outside, pulling heat away from the soil the same way sweat cools skin.

🌿 Three fixes, no transplanting needed:

- Double-pot — set the dark container inside a slightly larger light-colored pot with an air gap between the walls. The outer pot reflects heat, the air gap insulates, and soil temperature drops significantly with zero transplant shock

- Paint it — a coat of white exterior latex paint on a black pot changes its thermal behavior completely. One coat, ten minutes, and the pot reflects instead of absorbs

- Mulch the soil surface — two to three inches of straw or wood chips inside the pot reduces surface heating and slows evaporation between waterings

The plant you lost last summer may not have been under-watered. It may have been overheated by the container you never thought to question 🌱
