The 49x38x37 raised bed greenhouse is well made and quictent customer service is excellent.. I have 4 of these greenhouses for several years and one tube and one green house cover became damaged I contacted quictent by email and a response with directions for replacement was received by the next morning. The parts were out of warranty but the cost was really reasonable and included shipping..the process from start to finish was 5-6 days..during the process quictent kept in touch and also notified me it was delivered and does everything fit and function.. Definitely recommend Quictent customer service and product are 5 stars...
