Cold frames are used as the stepping stone for young plants between growing in a greenhouse and being transferred outdoors: if a plant is moved straight outside into the cold it can stunt its growth, so a cold frame is a great way to ease it into life in outside. The acrylic glazing of this practical cold frame is a safer alternative to glass that still lets plenty of light and warmth through. The two independently opening lids each have a prop so you can work without completely opening the cold frame and exposing your plants. We recommend using a weed block fabric to prevent weeds from growing in your cold frame and capture even more warmth. If using to grow food produce we recommend lining the bed with a membrane before adding the soil. Features and Benefits Long-lasting - The cold frame is manufactured using timber that has been Pressure Treated to give it a 15-year guarantee against rot. Easy self-assembly - This cold frame comes with full instructions for easy self-assembly. All year round use - For increased insulation and to deter weed, we recommend using a weed block fabric in the base of the cold frame Specifications Treatment: Pressure Treated Colour: Natural Timber Perfect as a transitional stage between the greenhouse and planting outside Manufactured from Pressure Treated timber for a superior build Two independently opening lids allow you to easily access your plants Acrylic glazing is a safer alternative to glass Guarantee: 15-year Anti-Rot Dimensions: H38 x W109 x D63cm Weight: 16.5kg Material: Mixed Softwood Manufactured from timber from sustainable sources Delivered flat packed for easy self-assembly Guarantee: 15-year Anti-Rot You will be contacted towards the end of your lead time by Forest Garden or their Courier with a delivery date.
