The beautifully crafted Large Timber Cold Frame from Forest Garden has a generous amount of room that will house any plants that are ready to be moved out of the greenhouse and into your garden. Cold frames are used as the stepping stone for young plants between growing in a greenhouse to be 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. The cold frame is manufactured using timber that has been Pressure Treated to give it a 15-year guarantee against rot. Comes with full instructions for easy self-assembly.

Every year prices for plants at local nurseries are rising, whilst the quality seems to have fallen. This permits the growing on for seedlings started indoors under glass. Solid construction. Easy to assemble with moderate DIY skills and tools.. Colin. Bournemouth, GB. Wed Jun 12 2019

Very hard to put together. You have to screw it all together, but there is no second holes to screw the screws into. So you have to make sure you line every piece up correctly. Also there is a gap at the side of the door (door is not big enough) which is not ideal for a greenhouse. More Brown than grey. Whilst in my basket deciding on whether to purchase, the price went up twice from £101 to £108. Really not worth the price.
