How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Powered fans and roll-up sides are different ventilation choices

Backyard Discovery Poppy combines a cedar frame, 4-wall polycarbonate covering, 1 exhaust fan and 2 casement windows. Savannah keeps cedar and 4-wall polycarbonate but adds 2 exhaust fans and 4 casement windows. Read that equipment as the maker's arrangement, not a prediction of indoor temperature.

ShelterLogic pairs steel frames with polyethylene fabric. Its larger Grow It designs describe roll-up sides and screened end vents, while the smaller backyard design describes screened end vents. Frame and cover choices are linked in this comparison; they are not independent ways to predict insulation.

The site plan comes before the kit order

The fields cannot determine temperature control, insulation or wind performance.

Check assembled footprint, working clearances, foundation, anchoring and local rules in the exact kit manual. Powered fans need suitable electrical provision. Follow the maker's ventilation guidance and monitor conditions for your plants rather than assuming that a fan-and-window count delivers the climate you need.

Before you buy

Will these filters tell me which kit fits my yard?

No. This finder compares construction. Check the exact assembled footprint, clearances, site preparation and local requirements on the linked product page and manual. Select a frame material, covering and ventilation arrangement to narrow this limited sample of greenhouse kits. These construction fields do not establish plant temperatures, insulation performance or weather resistance at your site. Check footprint, foundation, anchoring, local permits and the exact manual before buying. Powered fans need suitable electrical provision; monitor temperature and provide adequate airflow.

Does a powered fan guarantee temperature control?

Sun exposure, outdoor temperature, planting, openings and installation affect conditions. Monitor the greenhouse and follow the maker's ventilation guidance.
