Sporekill is great for cleaning wooden trays. Although plastic can line and protect the bottoms of the trays there is no good way of controlling the moulds on the sides of the boxes. Many of these contribute to spotting and quality loss during the crop.
Sporekill has high detergency for penetrating wood and when it dries it seals and traps mycelium and spores in wood thus reducing spores forming on the sides during cropping.
1.5-3 L Sporekill in 200L of water (0.75-1.5%) depending on cleaness of trays.
Plenty of volume is important as can be seen on the video.
In this farm, the trays are thoroughly wetted down after emptying and left on the yard for a week before reuse. Trays remain ‘cleaner’ during cropping.
