Save $36 on one of the best indoor greenhouses when you purchase this growing rack on sale. This no-frills greenhouse provides four sturdy shelves that hold up to 24 pounds each. Lock the wheels in place or remove them for extra stability once you’ve wheeled the rack into place.
A clear PVC cover protects plants from the elements while outside and traps in heat when inside. We love a greenhouse that does double duty.
For those who have several plants that need a home, this walk-in greenhouse—on sale for $20 off—is the next step up from one on wheels. It’s still a portable greenhouse thanks to easy-to-move anchors and a lightweight PVC cover—but 12 strong steel shelves and a durable frame ensure longevity. Stakes help secure this greenhouse to the ground to resist wind, giving it an edge on simple plant covers.
UV-Protected Mini Greenhouse
Even raised flower beds require a little TLC sometimes. This mini greenhouse fits over most standard-sized garden beds and offers protection against the wind, dust and curious animals. It’s affordable and portable, and the included UV-protected cloth cover is waterproof and easily rolls up to increase exposure to air and improve ventilation.
