PYEF CRAFTS DIY Closed Terrarium Kit, 34 oz
A complete kit for building a self-sustaining closed terrarium in a 1-liter cork-lidded glass jar, with soil, moss, charcoal, stones and bamboo tools (plant not included).

This Back to the Roots kit grows organic oyster mushrooms straight out of its box. Place it near a window with indirect light, mist with the included sprayer daily, and the listing says you'll be harvesting in about 10 days. Each crop yields three to four servings, and each box can grow up to two crops. It's organic, non-GMO and made in the USA, and it comes in giftable packaging.
Watching mushrooms visibly grow day by day is weirdly exciting, and you get to eat the result. It's one of the best under-$25 gifts for a foodie.
