Grow blocks are alive. We ship Monday, Tuesday, and Wednesday from Carthage so a box is not sitting in a warehouse over the weekend.

You pay shipping at checkout. The price is based on where the box is going. Orders of $150 or more ship free.

• Grow blocks ship fast (usually 1–3 days) because they are alive. We do not send live blocks by slow ground shipping.
• Freeze-dried jars keep in the pantry. They ship standard, which is cheaper.
• Start growing within 7–10 days of arrival for the best first harvest.
• If you will be out of town, wait to order — or keep the unopened bag in the refrigerator for a short hold (not the freezer).
• Very hot or very cold weather: we may hold a ship date and tell you why.

Local Smith County and Middle Tennessee pickup can be arranged — email Team@harmonixhome.com.
