Winter is the hardest time for plants in your greenhouse. You should clean insulate your greenhouse to give your plants as much heat and light as possible.
Brush, Detergent, Bubble-wrap, Plastic Clips
Clean the panels of the greenhouse with a brush or sponge, warm water and detergent.
Clean algae from the joins between the panels. Be careful not to damage the edges of the panels.
Place bubble-wrap inside the panels to add a layer of insulation and to keep out draughts.
Hold the bubble-wrap in place using plastic clips. Make sure to leave the ventilator free so that you can lower the temperature in the greenhouse if you need to.
