Over this frame goes our strongest 200gsm triple layered heat bonded ripstop translucent cover. it is waterproof and UV treated both inside and out and provides excellent illumination designed specifically to enhance plant growth and provide maximum protection. The cover is kept firmly in place with the 4 tie-down metal ratchets that ensure a tight and secure tensioning of the cover to the greenhouse frame and features a roll-up door measuring 1m x 2m high which has a strong and secure double zip for easy access. The sides roll up and are kept in place by bungee fasteners to allow a clever airflow system to operate inside the greenhouse to control the temperature. it also has front and back netted windows which help further control the temperature whilst also keeping out unwanted flying
