The 66 cubic Jiffy germination tray measures 53x31.5 centimeters and is therefore suitable for the measures of the most common serrette on the market.

Each plug is 5.5 cm high to ensure a better and more complete development of the root system.

The substrate is added with a polymer that guarantees the classic spongy porosity, so as to guarantee a minimum of 30-35% of air even at water saturation.

The plugs arrive wet and ready to use, with the addition of wetting agent (WA) for easy rehydration and to increase the entry of air inside them.
